2012 EWU Energy Efficiency &amp
Executive Summary
In keeping with Eastern Washington University’s new strategic theme, “Inspiring the Future”, the Facilities
team aims to motivate future students, staff and faculty through the University’s ongoing leadership in energy
efficiency and sustainability.
Continuing a long legacy of sensible investments in infrastructure and operational efficiency, Eastern
Washington University’s Facilities team has partnered with energy efficiency design/build firm McKinstry to
develop a comprehensive campus-wide Energy Efficiency and Sustainability Plan, carefully identifying
opportunities to reduce energy consumption and carbon emissions while improving campus operations.
This plan charts a course towards helping the University achieve its vision for a carbon neutral campus.
The Plan:
1. Establishes quantifiable methods to reduce greenhouse gas emissions
2. Develops ways to incorporate energy efficiency and sustainability into every aspect of the institution
3. Supports the University’s 2007 adoption of the American College and University Presidents’ Climate
Commitment (ACUPCC)
4. Accumulates audit findings of 16 buildings, identifying opportunities for energy and operational
savings
5. Assesses campus infrastructure for additional water and energy savings
6. Paves the way for actions to reach goals
Much has already been accomplished. This document describes past successes as well as current initiatives
and best practices. It also details opportunities for improvements to facilities and operations that can enhance
the campus master plan.
To implement the recommendations, the University has a range of financing options to consider:
•
Projects could be financed all at once, through a construction bond, paying for these investments with
savings in energy and operations.
•
Projects could be implemented in a phased approach over many years, as similar projects have been
since 2001. Table 1 below shows how this approach might be applied.
Whichever options the University pursues in coming years, implementation of the plan and completed projects
will yield quantifiable reductions in carbon emissions and improvements in energy efficiency, while continuing
stakeholder involvement will aid the University’s progress towards a sustainable, carbon-neutral campus that
instills environmental responsibility as a core value among students, faculty and administrators, and that
serves as a model for campuses nationwide.

project section of this document.
The Campus Energy Efficiency and Sustainability Study focuses on eight key areas:
1. Campus Energy Efficiency Projects & Greenhouse Gas (GHG) Emissions:
Eastern Washington University has been proactive in boosting energy efficiency and reducing
greenhouse gas emissions. This section highlights activities to date and gives an overview of campus
emissions.
2. Reducing Scope 1 & 2 Emissions:
As part of the study, Eastern Washington University directed McKinstry to audit 16 key facilities on
campus in an effort to drive energy efficiency and reduce emissions. This section highlights the
findings of this analysis, summarized in specific improvements recommended by McKinstry for each
building.
3. Reducing Scope 3 Emissions:
This section focuses on reducing Scope 3 Emissions; emissions directly or indirectly related to
transportation and waste stream management for the campus community.
4. Efficient and Sustainable Campus Systems:
In addition to buildings, we recognize that the physical campus environment has a big impact on our
overall sustainability impact. This is the most visible element. In this section, we explore
improvements to the physical campus environment.

Executive Summary
5. Renewable Energy and Offsets:
We explore renewable energy options in this section, with a focus on solar and wind. We also look at
the option of using different fuel sources for campus heating.
6. Energy Efficiency and Sustainability in Campus Culture:
This section focuses on Eastern Washington University’s commitment to communication and
stakeholder involvement as we continue to define a path to carbon neutrality.
7. Sustainability in Curriculum:
Eastern Washington University is committed to incorporating sustainability across the curriculum. The
University is working with faculty to achieve desired student learning.
8. Funding Energy Efficiency and Sustainability Projects:
As Eastern Washington University moves forward with implementation of various energy efficiency and
sustainability strategies, a key component of the University’s ability to affect these changes would be
funding strategies to accomplish this important work. Because this work involves addressing
infrastructure, deferring maintenance and upgrading existing systems, various approaches can move
the organization toward its goals. However, continuing the Facilities team’s plan requires the
University’s continued diligence in maintaining infrastructure, as well as ongoing commitment by the
administration to meet ACUPCC carbon emission reduction guidelines.

SUSTAINABILITY PROGRAMS
• In April 2011, Eastern Washington University’s Recycling Department celebrated Earth Day by calling
attention to present campus sustainability practices and accomplishments.
• The Recycling Department actively educates the University community on sustainability practices, promoting
programs such as self-service recycling, energy conservation, and sustainable foods (working with the
Sustainable Food Project student group).
• In June 2011, we began a compost collection pilot program in Dining Services, diverting food waste to the
Barr-Tech Composting facility and reducing our conventional waste stream in the process. In addition, the
dining operation is actively moving toward biodegradable, compostable take-out containers.
• Custodial Operations continues to integrate greener cleaning products.
• Installation of the artificial red turf on Roos Field has significantly reduced our irrigation needs.
• The University chips tree-pruning waste to create a springy, well-drained surface on the cross-country
running trail, reducing the waste stream in the process.
• Planting beds are top-dressed with composted grass clippings and mulched with pruning waste chips, which
reduces the waste stream, conserves irrigation water and cuts the need to buy mulch.
Campus Lighting Upgrades
• In the late 90s Eastern Washington University implemented a campus wide Lighting System Retrofit. This
project consisted of retrofitting energy inefficient T12 fluorescent lamps and standard magnetic ballast
fluorescent fixtures with energy efficient T8 lamps and electronic ballast, and replacing incandescent bulbs
with compact fluorescents. Most buildings on campus had their lighting retrofitted.
Eastern Washington University has been proactive in improving construction standards and specifications for
energy efficient equipment and systems. These facility improvements save roughly $365,540 in energy costs
and $281,461 in operational costs each year.
Currently, five major sustainable building projects have either been completed, are underway or are in various
stages of planning. Projects feature high-level leadership in Energy Efficiency and Design (LEED) certification
either approved, pending or projected:
•
•
•
•
•
Hargreaves is complete and certified LEED Gold
Patterson Hall is in progress and anticipating LEED Gold
Martin/Williamson pre-design report indicates potential for LEED Gold
University Recreation Center is complete and certified LEED Gold
University Science Center, Science I, is pre-design complete with LEED Gold as minimum
McKinstry and Eastern Washington University have created this Energy Efficiency and Sustainability Plan to
accomplish even more. As part of this, McKinstry completed facility audits on 16 campus buildings to identify
additional opportunities for Eastern Washington University to save energy, cut emissions and reduce costs.
This report details projects that will reduce emissions by a combined estimate of 6,650 MT CO2e. These FIMs
are detailed in Sections 2, 4, and 5 of this report.

MCKINSTRY’S ENERGY SAVINGS PERFORMANCE CONTRACT
Beginning with Eastern Washington University’s 2001 hiring of McKinstry as Energy Services Company
(ESCO), numerous energy efficiency projects have been completed, in four major phases:
PHASE ONE: 2002-2004
• Complete HVAC upgrades at Kingston and Isle Halls
• Controls upgrades at Martin, Tawanka, and Huston Halls
• Installation of variable frequency drives at buildings including Science Hall, JFK Library, Sutton Hall, and the
Art Building
• Installation of a new Computer Room Air Conditioning Unit in Huston Hall
• Rozell Central Chilled Water Plant improvements including installation of a 200-ton plate-and-frame heat
exchanger; replacement of a 750-ton cooling tower with a new 1,000 open-circuit, induced-draft cooling
tower, installation of Delta Digital Controls.
• Replacement of roll filters with filter banks in several air handing systems across campus
PHASE TWO: 2005-2006
• Aquatics Building: Structural analysis showed that a high humidity and chlorine environment had caused
excessive damage to the structural integrity to roof trusses. McKinstry replaced the existing HVAC system
with an energy efficient dehumidification system, installed a more efficient pool pump, improved lighting
throughout the building, repaired and painted the natatorium roof and associated trusses, installed a new
pool liner, and refitted the steam station with new steam valves.
PHASE THREE: 2007-2009
• Physical Education Activities Buildings: HVAC controls and lighting system upgrades in the Physical
Education Activities Buildings, Jim Thorpe Fieldhouse and the Pavilion (Reese Court). McKinstry replaced
eight air handling units, plus controls and installed ductwork throughout the gymnasiums.
• Physical Education Classroom Building: HVAC and lighting system upgraded, with construction staged to
keep half of the building occupied and running during construction. McKinstry installed a new variable air
volume air handling unit with fan wall technology in the basement and installed new ductwork, VAV terminal
units and piping distribution systems, digital controls, and energy efficient lighting fixtures throughout the
building.
PHASE FOUR: 2011-2012
• Rozell Central Steam Plant: Began replacement of the boiler feed water pumps to improve pump efficiency,
reliability and redundancy.
• Tawanka Hall: Began replacement of all electrical ovens with gas ovens, and the complete replacement of all
walk-in and reach-in coolers and freezers. This project improves the overall energy efficiency and
redundancy of the refrigeration and food storage systems.

Detailed Report
1. Energy Efficiency Projects To Date
Eastern Washington University has been one of the more progressive higher education institutions when it
comes to energy efficient and sustainability design of new buildings on the Cheney Campus as well as
aggressively pursuing energy conservation projects in their facilities. The design and construction standards
that the university employs are centered on having the most energy efficient systems possible installed for the
amount of money spent.
CAMPUS WIDE LIGHTING SYSTEM RETROFIT
In the late 90’s the university implemented a campus wide lighting system retrofit. This project consisted of
retrofitting fluorescent fixtures that had T12 lamps and standard magnetic ballast with T8 lamps and
electronic ballast, retrofitting energy efficient incandescent bulbs with compact fluorescent screw-ins. For the
most part a majority of the buildings on campus were done at this time. There were a few however that still
had T12 lamps and magnetic ballast, and energy inefficient HID lighting. Many of these remaining buildings
and facilities would be addressed later.
ENERGY SAVINGS PERFORMANCE CONTRACT
In 2001, the university sent out a Request for Qualifications for Energy Services Companies (ESCO) for
performance contracting services. Many ESCOs responded but only a few were shortlisted for interviews.
McKinstry was awarded the Performance Contract. The last part of 2001 and most of 2002 were spent
performing the energy audit and formalizing the contact. In late 2002 and all of 2003, the Phase 1 group of
projects consisted of complete HVAC upgrades at Kingston and Isle Halls, controls upgrades at Martin,
Tawanka, and Hustan Halls, installation of variable frequency drives at several buildings on campus (Science
Hall, JFK Library, Sutton Hall, and the Art Building to name a few), Computer Room Air Conditioning Unit in
Hustan Hall’s computer room, installation of a 200 Ton Plate and Frame Heat Exchanger in the Rozell Central
Chilled Water Plant, and replacing a 750 Ton cooling tower with a new open circuit, induced draft cooling
tower at Rozell. The central chilled water plant at Rozell also had the existing Staeffa Digital Controls replaced
with Delta Digital Controls. Several air handing systems across campus had their roll filters replaced with filter
banks as well. The first phase of work at EWU was successfully wrapped up in 2004.
In 2005, EWU and McKinstry entered into a second phase of work for several energy retrofits in the Aquatics
Building. The retrofits performed in this building were quite extensive. The existing false ceiling in the
Natatorium, spectator section, and lobby areas were rotting out and starting to fall. This was due to the high
humidity levels in the natatorium and the inability of the existing HVAC system to control the humidity in the
natatorium. An independent structural analysis was done on the roof trusses. It had been found that over time
the content of chlorine in the air had done significant damage to the trusses. McKinstry replaced the existing
HVAC system with an energy efficient Dehumidification system, new energy efficient pool pump, new lighting
system throughout the building, the natatorium roof was repaired and a special primer and paint for
Natatoriums was applied. A new pool liner was installed, and the steam station and steam valves were rebuilt
or retrofitted with new steam valves. The project was implemented over the summer of 2006 and was back up
and operating in time for the fall quarter. This project was one of the more notable projects McKinstry had
done on EWU’s campus.
In 2007, EWU and McKinstry embarked on a third phase of work that involved the upgrade of the HVAC and
Lighting systems throughout the athletic facilities. This third phase of work was broken up into 2 separate
phases of work. The first phase of work included work to be done throughout the Physical Education Activities
Buildings, Jim Thorpe Fieldhouse, and the Pavilion (Reese Court). The second phase of work would eventually
include the Physical Education Classroom (PEC) building. The work that was done in the first part of the third
phase of work included McKinstry replacing (8) air handling units and ductwork throughout the Physical
Education Activities (PEA) buildings and their respective pneumatic controls, with New air handling units,
CAMPUS ENERGY EFFICIENCY PROJECTS & GHG EMISSIONS
EASTERN WASHINGTON UNIVERSITY | ENERGY EFFICIENCY & SUSTAINABILITY REPORT
Energy Efficiency Projects & GHG Emissions
ductwork distribution systems, and digital controls. McKinstry also implemented lighting retrofits throughout
the PEA buildings, as well as the Pavilion and Jim Thorpe Fieldhouse.
In 2008 and 2009, McKinstry started the 2nd half of the third phase of work. This included the entire HVAC and
lighting system upgrade at the Physical Education Classroom (PEC) Building. The work was staged in a way
that allowed one half of the building to be worked on while the other half of the building was occupied and
running. A new variable air volume air handling unit using fan wall technology was installed in the basement
of the building while all new ductwork and piping distribution systems were installed throughout both floors of
the building. New variable air volume boxes with reheat coils were installed as well as new hot water
baseboard fin tubes on both floors of the building. New digital controls were installed as well as all of the
casework on the second floor. All new energy efficient lighting fixtures were installed throughout the project.
In 2011 McKinstry developed fourth phase projects to replace the boiler feed water pumps in Rozell’s central
steam plant as well as replacing all of the refrigeration and food storage systems and the electrical ovens in
Tawanka Hall. These projects are under contract and slated to be implemented in late 2011 and the first half
of 2012. The boiler feed water project will give the university an energy efficient means of pumping feed water
while offering a level of redundancy they have not had before. The Tawanka Hall project will have all of the
walk-in coolers and freezer getting replaced with more energy efficient refrigeration equipment and
compartment walls. The same will be done with the reach-in coolers and freezers. The electric ovens will be
replaced with gas fired ovens.
A lot of great energy efficiency projects have been implemented over the last 10 plus years, but there are
many more energy efficiency projects to do on campus. McKinstry and EWU have developed a very close
working relationship over the last 10 years and have developed an energy efficiency master plan with their
sights set on implementing more of this work in the future. The body of the work is presented in this report
represents the fruit of their labor. It is our hope that this acts as a compass for accomplishing this work.

2. 2007 Greenhouse Gas Inventory (GHG) Results
A. DATA COLLECTION
A team of Eastern Washington University faculty and staff compiled the 2007 Campus Greenhouse Gas
Inventory, reporting their findings to the ACUPCC. That inventory serves as the baseline for this report.
To ensure consistency and transparency, the greenhouse gas analysis follows the World Resources Institute
Greenhouse Gas Inventory Protocol; the accepted standard for emissions reporting, which groups emissions
into three categories, or “Scopes”:
• Scope 1: Direct Emissions – exhaust from campus buildings and vehicles, and fugitive emissions from
refrigerants.
• Scope 2: Indirect Emissions – from purchased electricity, purchased steam or chilled water, for example.
• Scope 3: Tertiary Emissions - business air travel, commuting by students, staff and faculty, solid waste
disposal and water consumption.
Eastern Washington University uses the Clean Air Cool Planet Campus Carbon Calculator, a campus-specific
inventory program that allows annual data updates, so as Eastern Washington University uses the calculator
over time it will show trends and identify opportunities to address emissions. Eastern Washington University’s
full 2007 GHG inventory report can be viewed on the ACUPCC website:

A. WEDGE GRAPH OF CARBON EMISSIONS
The wedge graph shown above details one potential course for reducing campus emissions. This initial
representation assumes an annual 3% emissions increase to account for University growth and the impact
that the following strategy implementation could produce. The scenario includes a 5 year implementation
schedule of all facility improvement measures (FIMs) identified in McKinstry’s facility study; a 1% annual
reduction of transportation (based on Scope 3 campus policies and programs); and a 0.75% annual emissions
decrease from regional transportation policies stemming from efficiency standards and expanded transit
options. The graph also illustrates the potential impact of a heavy future investment in renewable energy as
the technology becomes more affordable. The mitigation reduction levels shown in this graph will be updated
to accurately reflect Eastern Washington University’s goals and approach to carbon mitigation as they are
quantified. The red wedge represents the remaining balance in carbon offsets in any given year that Eastern
Washington University would need to pursue to mitigate emissions to claim carbon neutrality.
Note: this graph will evolve to reflect the impact of programs, measures and goals defined by campus stakeholders.
B. DISCUSSION OF GOALS - PERSPECTIVE ON PRIORITIZING PROJECT IMPLEMENTATION
Before beginning any capital facility improvement at Eastern Washington University, each building or
improvement will be evaluated for cost, impact, need and available funding. The facilities team and
stakeholder group can prioritize projects with consideration to their impact on campus carbon neutrality goals.
The stakeholder team will report to the university president and executive staff, to ensure that all
sustainability and emissions reduction strategies are in alignment with University goals.

Reducing Scope 1 & 2 Emissions
Executive Report
B. SUMMARY OF FINDINGS BY BUILDING
McKinstry believes that air handling systems and their controls present the best opportunity for energy
savings in these buildings. Each buildings’ air handling system and its current condition are summarized
below.
ART BUILDING
The building is served by three air handler units. AHU-1
and AHU-2 serve the second floor and the middle of the
first floor through a variable volume, dual duct system
with 100% OSA. AHU-2 has a dedicated exhaust fan
system. The two units share a glycol run-around loop to
recover energy from the tempered exhaust air,
transferring heat to the incoming air. The air is then
heated by a face-and-bypass steam pre-heat coil or
cooled by a chilled water coil. The air leaving either coil
is 55 degrees before going to the hot duct or cold duct.
The hot duct has two low-pressure steam coils (5 pounds
per square inch) that heat the air depending on what the
duct reset temperature specifies. The final tempering of the air is accomplished at the zone level by dual duct
Variable Air Volume (VAV) mixing boxes. This air handling unit and its respective boxes are controlled with
Staeffa digital controls.
AHU-3 serves the Lithographic Studio. It is a constant volume air handling unit, ventilating and tempering
100% outdoor air. This unit tempers the outdoor air with an air-to-air heat recovery unit with a rated
efficiency of 85%. The air is then heated to 55 degrees by a face-and-bypass steam preheat coil. This unit
serves three duct coils each, with a hot water coil and a chilled water coil. The final tempering of the air is
performed by the duct coils. The AHU and its coils are controlled with Staeffa digital controls.
AHU-4 serves the Woodshop and Studio. It is a constant volume air handling unit, ventilating and tempering
100% outdoor air. This unit initially tempers the outdoor air with an air-to-air heat recovery unit in the air
handler with a rated efficiency of 85%. The air is then heated to 55 degrees by a face-and-bypass steam
preheat coil. This unit serves three duct coils each, with a hot water coil and a chilled water coil. The final
tempering of the air is performed by the duct coils. AHU-4 and each duct coil are controlled with Staeffa digital
controls.
Due to the use of paint and other volatiles, this building has a large number of constantly-running exhaust
fans, even in spaces where there are no people working and no exhibits that require fresh air.

FIELD NOTES FROM PRELIMINARY ENERGY AUDIT
The Fine Arts Complex of the Eastern Washington University is comprised of five buildings: Art, Music,
Theater, Radio and TV, and Communications on the south side of the EWU campus in Cheney
Washington. McKinstry installed some variable frequency drives on the main air handling unit serving
the Art Building as well as its dedicated main building exhaust fan. A preliminary energy audit was
conducted on August 4, 2010 by McKinstry.
The Art Building (ART) was completed in 1972, and is
the center of the Fine Arts Complex. It is a two story
35,000 square foot building. The exterior walls have
red face brick over concrete masonry block walls. The
Art Building houses a Digital Lab, a ceramics and
sculpture studio, photography dark room, as well as
studios for painting, drawing, and printmaking. In
addition there are classrooms, exhibition area, and
faculty offices and a lecture hall. The window areas
are relatively small in square footage. The roof is
comprised of a built up membrane roof. The
occupancy rate is approximately 180 faculty/staff
members and students, Mondays through Fridays
throughout the school year. Operating hours are 7:00
AM to 8:30 PM through the school year. The summer has a reduced amount of hours and a much lower
occupancy rate.
PREVIOUS ENERGY RETROFITS
No previous mechanical retrofit work was completed by McKinstry; however there was a lighting retrofit and
HVAC upgrade in 97.
HEATING SYSTEM
Heating is provided to the Art Building by the Rozell Central Steam Plant. High pressure steam enters the
building through the utility distribution tunnel and comes into the steam station at 110 psi. The steam is then
reduced to 50 psi (medium pressure) which is used for the domestic hot water heater. The steam is reduced
even further to 15 psi. The 15 psi steam is used in the steam pre-heat coils in the air handling units (AHU-1,
3, and 4) serving this building. The 15 psi steam is used to heat water that is used in duct heating coils 1
through 6. The hot water is heated through steam/water converters. The hot water serves the fin-tube
convection heaters as well.
COOLING SYSTEM
Chilled water from the central plant is used in the cooling coils of the AHU’s serving the Art Building.
AIR DISTRIBUTION SYSTEM
The building is served by (3) Air Handler Units. AHU 1 and AHU 2 serves the 2nd floor and the middle of the
1st floor. It is a variable volume, dual duct system with 100 % OSA. The unit has a dedicated exhaust fan
system, AHU-2. AHU-1 has glycol run-around loop with AHU-2. This heat recovery coil recovers energy from

the tempered air getting exhausted and transfers the heat to the outdoor air getting introduced to AHU-1. The
air is then heated by a face and bypass steam pre-heat coil or cooled by a chilled water coil. The air leaving
either coil is 55 degrees before going to the hot duct or cold duct. The hot duct has (2) low pressure steam
coils (5 psig) that heat the air to the desired temperature depending on what the duct reset temperature is
calling for. The final tempering of the air is accomplished at the zone level by dual duct VAV mixing boxes.
This air handling unit and its respective boxes are controlled with Staeffa digital controls.
AHU-3 serves the Lithographic Studio. It is a constant volume air handling unit ventilating and tempering
100% outdoor air. This unit tempers the outdoor air with an air to air heat recovery unit in the air handler
with a rated efficiency of 85%. The air is then heated to 55 degrees by a face and bypass steam preheat coil.
This unit serves (3) duct coils each with a hot water coil and a chilled water coil. The final tempering of the air
is performed by the duct coils. Each duct coil served by AHU 3 and the air handler itself are controlled with
Staeffa digital controls.
AHU-4 serves the Woodshop and Studio. It is a constant volume air handling unit ventilating and tempering
100% outdoor air. This unit initially tempers the outdoor air with an air to air heat recovery unit in the air
handler with a rated efficiency of 85%. The air is then heated to 55 degrees by a face and bypass steam
preheat coil. This unit serves (3) duct coils each with a hot water coil and a chilled water coil. The final
tempering of the air is performed by the duct coils. Each duct coil served by AHU 3 and the air handler itself
are controlled with Staeffa digital controls.
Due to the use of paint, and other volatiles, this building has a large number of exhaust fans. It is believed
that the exhaust fans running 24/7 is what is causing such an issue with the air balancing between the supply
and exhaust. While on site and performing this survey, it was noted that all exhaust fans were running even in
spaces where there weren’t any people working or had exhibits that require the exhaust fans to be on.
SEQUENCE OF OPERATIONS:
1. The AHUs are running 6:00 am to 8:00 pm, Monday through Friday, Night setback is 55°F. Upon
request the unit will run on weekends and when the outdoor air temperature is 20°F and below the air
handlers will run 24/7.
2. Most of the exhaust fans are running 24/7 365 days a year.
3. There is no Cold Duct / Hot Duct Reset control strategies in place. This would be difficult to do on
AHU-1 with the steam coils serving the hot duct.
AREAS OF INTEREST
1. AHU 1 is the Supply Fan and AHU2 is the Exhaust Fan. The face and bypass damper does not close
tight.
2. A number of EF fans were not working: EF 8,9,11, 14, 16, 17 and 18. SF1 -possibly no belt.
3. An air balance of the entire system must be done in order to ensure that the system is working as
intended. The Kiln exhaust fans should only operate when the Kiln’s are in operation.
4. Additional Energy Saving control strategies could be employed.

COMMUNICATION BUILDING
A single air handler, AHU-3, serves this entire
building. The AHU is a constant volume, dualduct system that serves 76 mixing boxes in the
crawl space below the first floor and above the
false ceilings on the first and second floors.
The air handler and its mixing boxes are
pneumatically controlled. There is a Staeffa
Control System interface with the pneumatic
controls, however it appears that the dampers
are not sealing completely, and the system is
very limited in its energy management
capabilities.
The chilled water coil has a 3-way valve which
has been converted into a 2-way valve. There
were several small exhaust fans for the toilets.
The overall condition of this system is poor. Constriction of outdoor ductwork shows that the air intake must
be enlarged. The system has outlived its useful service life and should have the major components such as the
air handler and the mixing boxes replaced.

COMMUNICATION BUILDING
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT AUGUST 4 2010
The Fine Arts Complex of the Eastern Washington
University is comprised of five buildings on the south
side of the EWU campus in Cheney Washington.
McKinstry has not previously completed retrofits of
these buildings. A preliminary energy audit was
conducted on the Communications Building, Art
Building, Music Building, Radio & TV building, and
Theater Building on August 4, 2010 by McKinstry.
Due to the complexity of the buildings and their
respective HVAC systems this survey took several
days.
The Communications Building, completed in 1966, is
a two story 19,000 sf cement masonry block
building, with red face brick. Half of the building has
a basement. The building consists of classrooms and
faculty offices and is in operation from 8:00 AM to
8:00 PM during the academic year (September through May) and from 8:00 to 5:00 PM during the summer
(June through August). The occupancy ratio is 50 faculty/staff and 500 students.
PREVIOUS ENERGY RETROFITS
No previous retrofit work was completed by McKinstry in this facility. There was a lighting retrofit done
campus wide in the 2000 to 2001 time frame. The hallways in the Communications Building seem to be
inadequate and under lit.
HEATING SYSTEM
The facility is heated by steam from the Central Plant at Rozell Hall. The steam from the plant enters the
building at 110 psi and is reduced to medium pressure at 46 psi and then to low pressure at 12 psi through
pressure regulation stations. The low pressure steam is used in the air handling unit steam coil via 1/3-2/3
steam control valves. There is currently no steam to water converter. The condensate return system employs
a single pump Condensate pump.
COOLING SYSTEM
Chilled water from the central Plant at Rozell Hall is used in the Air Handler to provide cooling. The AHU has a
tertiary chilled water booster pump for circulating the chilled water through the AHU’s chilled water coil.
AIR DISTRIBUTION SYSTEM
There is one Air Handler, AH-3, which serves the entire building. The AHU is a constant volume, dual duct
system that serves (76) mixing boxes located in the crawl space below the first floor and above the first floor’s
false ceiling. There are a few mixing boxes located above the 2nd floor’s false ceiling. The air handler’s outdoor
air opening is too small and will need to be made larger. This is evident by the outdoor air ductwork
constricting.
The air handler and its mixing boxes are pneumatically controlled. There is a Staefa Control System interface
with the pneumatic controls, however it appears that the dampers are not sealing completely, and the system
is very limited in its energy management capabilities. The chilled water coil has a 3-way valve which has been

Reducing Scope 1 & 2 Emissions
converted into a 2-way valve. There were several small exhaust fans for the toilets.
The overall condition of this system is not very good. The system has outlived its useful service life and should
have the major components such as the air handler and the mixing boxes replaced.
SEQUENCE OF OPERATIONS
The air handler operates Monday through Friday, 6:00 am to 8:00 pm. The air handler will operate on
weekends on request. When the outdoor air temperature is below 20°F, the air handler will run 24/7. It is
believed that the AHU sometimes operates continuously during the cooling season. This is due to the
operating schedules not being re-implemented. The air handler has a night setback temperature of 55°F.
The air handler doesn’t have a morning warm-up / cool-down sequence or a morning purge sequence. When
the unit starts up in the morning the dampers go to their minimum position.
There is no Cold Duct/Hot Duct Reset control strategy or economizer control strategy in place. Over all the
controls capability for energy management is very limited.
FURTHER INVESTIGATIONS
Jim Butler, the EWU Plumbing supervisor noted that the steam station and the steam traps were in poor
condition. They components of the steam station such as the gate valves and steam traps need to get
replaced.
The condensate receiver next to the steam station has had and currently does have a leak which results in the
condensate running out onto the floor in the mechanical room.

EASTERN CHILDREN’S CENTER (ECC)
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT AUGUST 4, 2010
OVERVIEW
The Eastern Children’s Center (ECC) of the Eastern Washington
University is on the south side of the EWU campus in Cheney
Washington on the corner of Washington and Seventh Street.
McKinstry has not previously completed any retrofits at this
building. A preliminary energy audit was conducted on August
4, 2010 by McKinstry.
The ECC is a single story structure, 14,000 square foot red
brick façade/stucco building which was completed in 2002
following the Phase 2 Campus Expansion. The Mechanical
Room is in the attic and there is no basement. It currently
provides full time, part time and after-school child care for 194
children from ages 6 weeks to 10 years old. The operating
hours are 7:00 AM to 6 PM Monday through Friday all year. The
security of the children is very important and access to the
building is limited.
PREVIOUS ENERGY RETROFITS
The building was built in 2 phases with the first phase starting in 1999. The other phase started in 2000.
Construction was completed in 2002/2003 time frame.
HEATING SYSTEM
The facility uses low pressure steam from the central Steam plant for the heating. The steam enters the
building at 110 psi and is reduced to 33 psi and then to 12 psi through the steam steam station, which has 2
pressure reducing valves. The low pressure steam is used for AHU’s preheat coil and for the steam/water
converter for the reheat valves in the VAV boxes. A single pump in the condensate receiver is use for
pumping the condensate back through the utility tunnels back to the central steam plant in Rozell. Heating hot
water is circulated through-out the building by (2) redundant hot water pumps, HWHP 1 and HWHP 2 are
COOLING SYSTEM
Chilled water from the central chilled water plant is used in the cooling coil of the AHU. There are two fully
redundant pumps that circulate the chilled water through the coil, CWP 1 and CWP2.
AIR DISTRIBUTION SYSTEM
There is one variable air volume air handling unit that serves the entire building. The air handler is a Pace
custom air handler. The unit has a dedicated supply and return fan that utilize econo-disc for varying the
volume of air. During our site survey McKinstry was informed that the econo-disc in the supply fan was not
working as intended and thus the entire ventilation system has been operating in a constant volume mode of
operation.
The air handler serves (18) VAV boxes that vary the volume of air according to what their respective zone is
calling for as determined by its respective digital thermostat. Each VAV box has a hot water reheat coil. The
HVAC systems serving the ECC are controlled and monitored by Staeffa Digital Controls, which are no longer
supported.

JIM THORPE FIELDHOUSE
The HVAC system consists of four AHUs. AHUs 1 and
2 serve the Fieldhouse; AHU-3 serves both racquetball
courts; AHU-4 serves the hallway area between the
Fieldhouse, Aquatics, and the Pavilion.
AHU 1, 2, and 3 each have return air capabilities, a prefilter bank, and a steam pre-heat coil. AHUs 1 and 2
(referred to as H&V Units 1 & 2) supply tempered air
through their respective rotating turret diffusers. The air
from the Fieldhouse air handlers is unevenly
distributed, causing problems with NCAA competitions
when the high-velocity airflow actually interferes with
game play, altering the trajectory of balls. The air
handlers are pneumatically controlled. AHUs 1 and 2
each have just one control valve for their respective
steam pre-heat coils. AHU-4 has a dedicated return
fan.

JIM THORPE FIELD HOUSE
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT JULY 29, 2010
OVERVIEW
The Athletics Complex of the Eastern Washington
University is comprised of several buildings on the
west side of the EWU campus in Cheney
Washington. McKinstry has previously completed
retrofits of the HVAC, Controls, and Lighting
systems in the Aquatics Building, most of the
Physical Education Activities Buildings, Jim Thorpe
Fieldhouse, The Pavilion (Reese Court), and the
Physical Education Classroom (PEC) Building. A
preliminary energy audit was conducted on the
remaining systems not retrofitted in the PEA
Building, Jim Thorpe Fieldhouse, and the Pavilion on
July 29, 2010 by McKinstry.
JIM THORPE FIELD HOUSE
The Jim Thorpe Field House currently houses various
indoor athletic activities such as various sports
camps, ROTC, baseball team practices, golf, NCAA
Tennis, and track and field all year long. The building is west of the PEA building complex, and can be
accessed through the PEA building. It is a single story structure that has quite tall possibly 30 feet or higher.
The facility, built in 1976, resembles an airplane hanger with neither basement nor windows. The conditioned
floor space is 51,316 square feet. The walls from the exterior appear to be poured concrete and the roof is a
built-up membrane roof.
PREVIOUS ENERGY RETROFITS
Previous retrofit work completed by McKinstry in this facility consisted of retrofitting (84) 1500W indirect HPS
fixtures with energy efficient (6) lamp T5HO high Bay fixtures in 2007. Needless to say this single lighting
retrofit resulted in a significant reduction in the electrical load.
HEATING SYSTEM
The heating system serving the Jim Thorpe Fieldhouse is provided by the Campus Central Steam Plant. The
steam pressure coming into the building is 100 psi and is reduced to 15 psi steam at the steam station. The
heating system serves (4) air handling units with steam pre-heat coils or a steam hot deck coil. Steam is also
used for heating hot water via a converter, and then the hot water is used throughout the hallways between
the Aquatics Building, the Pavilion, and the Fieldhouse. Low Pressure steam is also utilized by (3) steam unit
heaters and (1) fan coil unit on the far south end of the field house. The steam traps for the main AHUs
serving the Fieldhouse itself are not easily accessible. There is a reset schedule on the Hot water heating
system. ATS controls the converter and hot water system. The horizontal condensate pipe has been reported
to be in rough shape and thinning.
COOLING SYSTEM
There is only one air handling unit that has cooling capabilities. AHU 4 which serves the hallway area between
the field house, Aquatics, and the Pavilion uses chilled water from the central chilled water plant in Rozell.
REDUCING SCOPE 1 & 2 EMISSIONS
EASTERN WASHINGTON UNIVERSITY | ENERGY EFFICIENCY & SUSTAINABILITY REPORT
Reducing Scope 1 & 2 Emissions
AIR DISTRIBUTION SYSTEM
The HVAC system consists of four AHU’s. AHU’s 1 and 2 serve the Fieldhouse while AHU-3 serves the (2)
Racquetball Courts, and then AHU-4 serves the Hallway area between the Fieldhouse, Aquatics, and the
Pavilion.
AHU 1, 2, and 3 each have return air capabilities, pre-filter bank, and a steam pre-heat coil. AHUs 1 and 2
(referred to as H&V Units 1 & 2) supply their tempered air through their respective rotating turret diffusers.
The air from these air handlers is not evenly distributed which causes problems with NCAA competitions when
the high velocity of air interferes with the trajectory of the balls getting used in the particular competition
taking place in the fieldhouse. The air handlers are pneumatically controlled. AHUs 1 and 2 each have just one
control valve for their respective steam pre-heat coils.
AH-4 has a dedicated return fan.
SEQUENCE OF OPERATIONS
1. All (4) air handling units operate 24 hours a day seven days a week. Their energy management
control capabilities are significantly limited to nonexistent.
2. No economizer controls or demand control ventilation control strategy.
AREAS OF INTERESTS
1. Replace all (4) air handling units with new air handling units and associated ductwork distribution
systems for the fieldhouse area. Install all new digital controls on all (4) new AHUs and implement
energy saving control strategies.
2. Replace all steam station valves and traps.

JOHN F. KENNEDY L IBRARY
There are 10 air handling units that serve
this building. AHU 1 through AHU 7 are dual
fan, dual duct VAV fan systems, each with a
dedicated return fan. The hot duct supply
fan, cold duct supply fan, and the
corresponding return fan are all controlled
with variable frequency drives. The VAV air
handlers serve 193 dual-duct, VAV mixing
boxes. These air handlers serve the general
reading areas and offices throughout the
library. The hot duct fan and the cold duct
fan each have a heating hot water coil,
while cold duct fans have chilled water coils.
The hot duct fan receives 100% outdoor air while the cold duct fan mixes the outdoor air with the return air.
AHUs 8 and 9 serve the archive areas. Both of these air handlers are constant-volume, variable-temperature
units that maintain humidity in their respective areas they serve. They have a direct expansion coil for cooling
and dehumidification purposes. They also have heating hot water coils and humidifiers.
AHU-10 is a constant-volume, variable-temperature air handler serving the Auditorium. The air handler has a
dedicated return fan, a hot water heating coil and a chilled water coil. It has the same operating hours as the
other AHUs serving the library building, even though the auditorium sees intermittent use.
All of the HVAC systems are currently controlled by dated Staeffa digital controls, which are a growing
maintenance burden due to the difficulty of finding replacement parts.

JOHN F. KENNEDY LIBRARY
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT - AUGUST 10, 2010
OVERVIEW
The John F. Kennedy Library of the Eastern
Washington University is in the center of the
EWU campus in Cheney Washington.
McKinstry has previously completed minor
retrofits in this facility. A preliminary energy
audit was conducted on August 10, 2010 by
McKinstry.
BUILDING NAME
The John F. Kennedy Library is a 153,000
square foot facility, originally completed in
1968 and was expanded and remodeled in
1998. It is widely viewed as one of the
nicest facilities on the EWU campus. The exterior walls are comprised of red face brick and large areas of
energy efficient Low E glazing. The exterior walls help give the building it’s character. This building operates
year round, but has reduced hours during the Summer and between session periods. There are 43
employees, and can serve up to 300 to 400 students/visitors daily. Normal operating hours are as follows:
Monday-Thursday: 7:30am to 8pm, Friday: 7:30am to 6pm Saturday: Closed, and Sunday: 1pm to 8pm.
PREVIOUS ENERGY RETROFITS
McKinstry replaced all of the econo-disc in each of the Dual Fan Dual Duct VAV systems with VFDs in the JFK
Library Building in 2003.
HEATING SYSTEM
High pressure steam comes into the building at 110 psi and then gets reduced to 50 psi and then again down
to 15 psi. This is done at the steam reducing station. The medium pressure steam is utilized at the
instantaneous DHW heater.
COOLING SYSTEM
Cooling is provided by the campus chilled water system. Chilled water is circulated from the Rozell building to
the campus distribution loop. Chilled water is pumped at AHUs 1 through 7 and AHU-10 via small coil pumps.
AHUs 8 and 9 use direct expansion coils for dehumidification purposes.
AIR DISTRIBUTION SYSTEM
There are 10 Air Handlers. AHU 1 through AHU 7 are Dual Fan, Dual Duct VAV fan systems. Each of these
AHUs has a dedicated return fan. The Hot Duct supply fan, cold duct supply fan, and the corresponding return
fan are all controlled with variable frequency drives. The VAV air handlers serve (193) dual duct variable air
volume mixing boxes. These air handlers serve the general reading areas and offices throughout the library.
The hot duct fan and the cold duct fan each have a heating hot water coil. The cold duct fan has a chilled
water coil. The hot duct fan receives 100% outdoor air while the cold duct fan mixes the outdoor air with the
return air.
AHU-8 and AHU-9 serve the archive areas. Both of the air handlers are a constant volume, variable

temperature air handler. These units maintain the humidity in their respective areas they serve. They have a
direct expansion coil for cooling and dehumidification purposes, heating hot water coil and humidifiers.
AHU-10 is a constant volume, variable temperature air handler that serves the auditorium. The air handler has
a dedicated return fan. The AHU has a hot water heating coil and a chilled water coil. It has the same
operating hours as the other AHUs serving the library building, even though the auditorium sees intermittent
use.
All of the HVAC systems are currently controlled by the existing Staeffa Digital Control system. The Staeffa
controls are becoming an ever increasing maintenance burden. It is becoming increasingly difficult to find and
acquire replacement parts.
SEQUENCE OF OPERATIONS
The air handlers 1 through 7 and 10 run from 5:30 am till 10 pm Monday through Sunday year round. The
Dual Fan Dual Duct VAV systems reset their respective hot ducts and cold ducts. EWU uses the economizer
control strategy as well.
1. Implement a morning Warm-up / Cool-down and morning purge control strategy.
2. Implement a Demand Control Ventilation Control strategy in areas served by AHUs 1 through 7 and
#10.
3. Event Scheduling on AHU#10.
AREAS OF INTEREST
1. There are very limited switching capabilities of the lighting. The light switches are in four quadrants.
2. There are a significant amount of HID fixtures at the north and south end of the building.
3. Retrofit the existing Staeffa Controls System with one of the approved controls contractors on
campus.

MARTIN HALL
Approximately 80% of the conditioned square footage in
Martin Hall is served by the dual-fan, dual-duct VAV air
handling system. The cold duct supply fan is located on
the first floor of Martin Hall while the hot duct fan is
located directly above the cold duct fan on the second
floor. Both air handlers bring in outdoor air and mix it with
return air from the plenum. There is one return air fan
that serves both supply fans. The cold duct fan has a
chilled water coil but no pre-heat coil. The hot duct fan
has a steam heating coil that heats the mixed air to the
desired set point of the hot duct. This air handling system
serves VAV mixing boxes throughout the areas served by
this air handling system. The cold duct fan is labeled AHU1 and the hot duct fan is labeled AHU-2.
The lab area on the 2nd floor is served by AHU-3, which
ventilates and tempers 100% outdoor air. The AHU has an
air-to-air heat exchanger that tempers the outdoor air
with the exhaust air, the air is then heated with a steam
coil, and cooled with a direct expansion coil. The
corresponding condensing unit is on the roof by AHU-4’s penthouse mechanical room.
The Auditorium is served by AHU-4, a constant volume, variable temperature air handing unit with return air
capabilities but no return fan. This air handler has a chilled water coil and a steam heating coil. There have
been ongoing comfort complaints. The zones at the end of the duct run appear to be starved for air.

MARTIN HALL
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT AUGUST 18, 2010.
OVERVIEW
Martin Hall is located in the center of Eastern Washington
University campus in Cheney, Washington. McKinstry has
not previously completed any retrofits. A preliminary
energy audit was conducted on August 18, 2010 by
McKinstry.
MARTIN HALL
Martin Hall is a two-story, 57,000 square foot masonry
brick structure which was completed in 1937. It houses the
departments of Education and Counseling, as well as
Educational and Developmental Psychology and has
classrooms and faculty offices. The operation hours are
from 7:00 am until 7:00 pm, Monday through Friday during
the academic year and reduced operating hours during the
summer. The occupancy is 31 faculty/staff to 750 students.
PREVIOUS ENERGY RETROFITS
In 2003, McKinstry implemented some energy efficiency
retrofits. Variable frequency drives and digital controls
were installed on the HVAC equipment serving Martin Hall.
Energy saving control strategies were implemented.
HEATING SYSTEM
Heating is provided to Martin Hall by the Rozell Central Steam Plant. High pressure steam enters the building
through the utility distribution tunnel and comes into the steam station at 110 psi. The steam is then reduced
to 50 psi (medium pressure) which is used for the domestic hot water heater. The steam is reduced even
further to 15 psi. The 15 psi steam is used in the steam pre-heat coils in the air handling units (AHU-1/2, 3
and 4) serving this building. The hot water is heated through a steam/water converter. The hot water serves
the fin-tube convection heaters as well. There are (2) hot water pumps that circulate water throughout Martin
Hall.
COOLING SYSTEM
Chilled water from the central plant is used in the cooling coils of the cold duct supply fan. There is a single
chilled water pump that circulates chilled water to AHU-1 and AHU-4.
AIR DISTRIBUTION SYSTEM
Approximately 80% of the conditioned square footage in Martin Hall is served by the dual fan, dual duct
variable air volume air handling system. The cold duct supply fan is located on the first floor of Martin Hall
while the hot duct fan is located directly above the cold duct fan on the 2nd floor. Both air handlers bring in
outdoor air and mix it with return air from the plenum. There is one return air fan that serves both supply
fans. The cold duct fan has a chilled water coil but no pre-heat coil. The hot duct fan has a steam heating coil
that heats the mixed air to the desired set point of the hot duct. This air handling system serves variable air
volume mixing boxes throughout the areas served by this air handling system. The cold duct fan is labeled
REDUCING SCOPE 1 & 2 EMISSIONS
EASTERN WASHINGTON UNIVERSITY | ENERGY EFFICIENCY & SUSTAINABILITY REPORT
Reducing Scope 1 & 2 Emissions
AHU-1 and the hot duct fan is labeled AHU-2.
The lab area on the 2nd floor is served by AHU-3. AHU-3 ventilates and tempers 100% outdoor air. The AHU
has an air to air heat exchanger that tempers the outdoor air with the exhaust air, the air is then heated with
a steam coil, and cooled with a direct expansion coil. The corresponding condensing unit is on the roof by
AHU-4’s penthouse mechanical room.
The auditorium is served by AHU-4. AHU-4 is a constant volume, variable temperature air handling unit with
return air capabilities but no return fan. This air handler has a chilled water coil and a steam heating coil.

EASTERN WASHINGTON UNIVERSITY/THE PAVILION
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT JULY 29, 2010
OVERVIEW
The Athletics Complex of the Eastern Washington
University is comprised of several buildings on the
west side of the EWU campus in Cheney Washington.
McKinstry has previously completed retrofits of the
HVAC, Controls, and Lighting systems in the Aquatics
Building, most of the Physical Education Activities
Buildings, Jim Thorpe Fieldhouse, The Pavilion (Reese
Court), and the Physical Education Classroom (PEC)
Building. A preliminary energy audit was conducted on
the remaining systems not retrofitted in the PEA
Building, Jim Thorpe Fieldhouse, and the Pavilion on
July 29, 2010 by McKinstry.
THE PAVILION
The Special Events Pavilion (Reese Court), completed in 1975, is a multiuse facility which seats 5000. It is
primarily the University’s basketball court, but also houses concerts, dances, and graduations ceremonies year
round. In addition it has training rooms and locker rooms for volleyball, wrestling, and football teams as well
as business offices. The building is a two story 119,000 sf structure where the center court (107 X 171 feet) is
below grade, and seating is at grade level and mezzanine level. Most of the equipment, training and locker
rooms are located on the lower level. The walls from the exterior appear to be poured concrete and the roof is
a built-up membrane roof. The windows are tinted low-E thermo pane windows.
PREVIOUS ENERGY RETROFITS
Previous retrofit work completed by McKinstry in this facility consisted of a lighting retrofit in 2007.
HEATING SYSTEM
The heating system serving the Pavilion is provided by the Campus Central Steam Plant. The steam pressure
coming into the building is 100 psi and is reduced twice. The steam goes through a reducing station where it
is first reduced to 25 psi and then again to 15 psi steam. The 25 psi steam is used for the domestic water
system
The heating system serves five air handling units with steam pre-heat coils. Steam is also used for heating hot
water via a converter. The heating hot water is used for unit heaters, fan coil units and baseboard heaters.
There is a reset schedule on the hot water heating system.
Medium pressure steam is used for domestic hot water (DHW).
Kerry Pease’s office is heated by the unit heaters. The Eastside and the Westside offices are each served by
(4) 4-pipe return air only fan coil units.
COOLING SYSTEM
The cooling system uses chilled water from the central chilled water plant in Rozell. Chilled water is used in all
but one of the air handling units.

AIR DISTRIBUTION SYSTEM
The HVAC system consists of four (4) constant volume variable temperature air handler units and (1) constant
volume multi-zone unit. AHU 1 and 2 serves the areas on the first floor underneath the seating areas in the
coliseum. The spaces served by these units consist of meeting rooms, conference rooms, locker rooms,
bathrooms, and the training room. AHU-3 serves the equipment issue room. AHU-4 and AHU 5 serves the
coliseum court, and seating areas. All (5) of these units are controlled with pneumatic controls.
AHU-1 is a heating only air handing unit that has return air capabilities and a dedicated return fan. This air
handling unit has a pre-filter, and a serpentine steam pre-heat coil.
AHU-2 has a pre-filter, and a dedicated return fan. The air handling unit has a steam pre-heat coil and a
chilled water coil for the hot deck and cold deck. The multi-zone unit serves 2 separate zones.
AHU-3 is could be classified as a 4-pipe vertical fan coil unit. This unit serves the athletic equipment room.
AHU-4 and AHU-5 are both built up air handing units. They each have a dedicated return air system and
return fan. Their respective fans are axial vane fans on the supply and return fans. Due to the type of fan that
is installed there is sound attenuators on the supply and discharge side of each fan, which adds a significant
pressure drop.
SEQUENCE OF OPERATIONS
1. The AHUs run 24/7.
2. There are no reset schedules or other basic control strategies.
3. There is no HW reset schedule.
AREAS OF INTEREST
1. The Training areas and offices have problems with ventilation. Training Room appears to have no
ventilation, although there was ductwork in the hung ceiling. It could not be determined at the time of
the audit where these ducts ran. Which air handler serves the locker rooms also needs to be
determined.
2. AHU 1 has an OA intake source off of a parking lot.
3. The East side and West side offices are served by return air only fan coil units, which could be
replaced by air handling units on the roof.
4. AHU 4 & 5 supply and return fans are dual rated. The Supply Fan is listed with a 30 HP and a 37 HP
motor. The Return fan is listed as a 15 HP and a 20.4 HP motor. There might be some redundancy in
motor capacity.

PHYSICAL EDUCATION ACTIVITIES BUILDING (PEA)
AHU 9 and 10 hang from the gymnasium ceiling, serving the
body shop. Both are constant-volume, variable-temperature
air handler units with pre-filters and serpentine, lowpressure steam pre-heat coils, and both have return-air
capabilities. The units are loud and because they are
manually switched on and off, staff keeps them switched off
most of the time when the space is occupied. Because the
starter/disconnects for each of these units is 12 feet or more
above the gymnasium floor, a ladder is needed to switch on
these units. Meanwhile, pneumatic controls limit the energysaving control strategies of these units.

Detailed Report
EASTERN WASHINGTON UNIVERSITY/PHYSICAL EDUCATION ACTIVITIES - THE BODY SHOP (GYM 270)
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT JULY 29, 2010
OVERVIEW
The Athletics Complex of the Eastern Washington University is
comprised of several buildings on the west side of the EWU
campus in Cheney Washington. McKinstry has previously
completed energy retrofits of the HVAC, Controls, and
Lighting systems in the Aquatics Building, most of the
Physical Education Activities Buildings, Jim Thorpe Fieldhouse,
The Pavilion (Reese Court), and the Physical Education
Classroom (PEC) Building. A preliminary energy audit was
conducted on the remaining systems not retrofitted in the
PEA Building, Jim Thorpe Fieldhouse, and the Pavilion on July
29, 2010 by McKinstry.
THE BODY SHOP
The former Body Shop, recently renamed Gym 270, is located in the Physical Education Activities Building.
Gym 270 is a multi-purpose room featuring an open floor which can be used for volleyball and badminton
courts, and small to medium sized activity. The room is used all year round when classes are in session,
starting at 7:00 AM. The occupancy is from 7 am to 9 pm, Monday through Friday, and from 7 am till 7 pm
on Saturdays and Sundays. This is a two story structure with 1 foot poured concrete walls and a built up
membrane roof. There are no windows in the facility.
PREVIOUS ENERGY RETROFITS
No previous retrofit work completed by McKinstry in this facility.
LIGHTING SYSTEM
The lighting system in the body shop consists of 1000 Watt high pressure sodium fixtures. The lighting in the
Dance Studio, hallways on either side of the inside entrance to the field house, and the Raquetball Courts are
energy inefficient and should be considered for retrofits.
HEATING SYSTEM
The heating system serving the Gym 270 is provided by the Campus Central Steam Plant. The steam pressure
coming into the building is 100 psi and is reduced twice, first to 25-50 psi at the steam station, and then again
down to 10 to 15 psi. Medium pressure steam is also used for domestic hot water (DHW).
The heating system serves two air handling units with steam pre-heat coils. Steam is also used for heating hot
water via a converter, and then the hot water is used for unit heaters, fan coil units and baseboard heaters.
There is also a laundry with four steam dryers. There is a reset schedule on the hot water heating system
(180 ° F to 12O ° F). ATS controls the converter and hot water system. Three pumps are associated with the
hot water system, with one being located in the PEA building while the other 2 are in the Jim Thorpe Field
house. The pumps are lead/lagged in the Field House.
COOLING SYSTEM
The AHUs in the body shop do not have cooling capabilities. They do not have economizer capabilities.
REDUCING SCOPE 1 & 2 EMISSIONS
EASTERN WASHINGTON UNIVERSITY | ENERGY EFFICIENCY & SUSTAINABILITY REPORT
Reducing Scope 1 & 2 Emissions
AIR DISTRIBUTION SYSTEM
The HVAC systems serving the body shop consists of two (2) constant volume variable temperature air
handler units. Each unit is hung from the ceiling in the gymnasium, and has a pre-filters, and a serpentine low
pressure steam pre-heat coil. These units have return air capabilities. The units are turned on and off
manually, and one of the issues with these units is that they are loud which is why they are turned off a
majority of the time when the space is occupied. The nomenclature/designation for these units is AHU 9 and
10. These air handlers are pneumatically controlled, and the starter/disconnects for each of these units is 12
or more feet off the gymnasium floor so it takes someone with a ladder to turn these units on. The pneumatic
controls limit their energy saving control strategies.
This FIM will require and adjusted baseline like it was done for the air handling units in Gymnasiums 264 and
265.
SEQUENCE OF OPERATIONS
1. If the units were not so loud they would run 24/7.
2. No energy saving control strategies of any sort are employed.
AREAS OF FURTHER INVESTIGATION
1. The laundry dryers are run off steam, check to see if savings would result from replacing with gas
fired dryers.
2. According to Jim Butler, EWU Plumbing supervisor, the condensate return piping coming from AHU’s 9
and 10 is getting thin and will require replacement in the not to distant future.
3. Replace AHU’s 9 & 10 with a similar retrofit that was performed in Gyms 264 and 265.
4. Perform the lighting retrofit in the Gym 270, the Dance Studio, hallways on either side of the
fieldhouse, and the racquetball courts.

EASTERN WASHINGTON UNIVERSITY/RADIO-TV BUILDING
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT - AUGUST 4, 2010
OVERVIEW
The Fine Arts Complex of the Eastern Washington University is comprised of five
buildings: Art, Music, Theater, Radio-TV, and Communications on the south side of
the EWU campus in Cheney Washington. McKinstry has not previously completed
retrofits of this complex. A preliminary energy audit was conducted on August 4,
2010 by McKinstry.
RADIO/TV BUILDING (RTV)
Midnight daily.
The Radio-TV Building (RTV) is part of the Fine Arts Complex which was completed
in 1972. It is a two story 16,000 square foot concrete masonry block building with
red face brick. The facility consists of classrooms and laboratories, offices, a
campus radio station KEWU, a TV studio, and 2 screening rooms seating 50 and 30
people. The windows are double pane. The occupancy ratio is 20 to 30 faculty/staff
members and 200 students. Operating hours for the classroom area are 8:00AM to
9:00 pm during the academic year. The radio station operates 6:00 AM to
PREVIOUS ENERGY RETROFITS
No previous mechanical retrofit work was completed by McKinstry in this facility, however the lighting systems
had been retrofitted to energy efficient lighting in the 2000 – 2001 time frame.
HEATING SYSTEM
The heating system serving the RTV building is provided by the campus central steam plant. The steam
pressure coming into the building is 100 psi and is reduced twice. The high pressure steam is first reduced to
22 psi steam and then further reduced to 15 psi. The medium pressure steam is utilized for the domestic hot
water system while the low pressure steam is used for heating at the air handling unit. The components at the
steam station such as the valves and steam traps are in need of getting replaced. Jim Butler, the Pipefitter
and Plumbing Supervisor for EWU, noted that the steam station and condensate system was in poor condition
and certain components should be consid3red for replacement.
The Condensate return system has one receiver with a single condensate return pump. The steam traps were
not easily accessible.
There is no heating hot water converter, but the building has two domestic hot water heaters, one is electric
and the other is steam.
COOLING SYSTEM
Chilled water from the central plant is used in the cooling coil of the AHU.
AIR DISTRIBUTION SYSTEM
The air handler serving this building is a constant volume, dual duct air handler that serves (41) constant
volume mixing boxes. The air handler has a dedicated return fan, has a pre-filter, low pressure steam coil of
the serpentine type, and a chilled water coil. This unit and its corresponding mixing boxes are controlled with
pneumatic controls and have a Staeffa Digital controls interface. The controls are very limited in their energy
management capabilities.

There is no Economizer Control Strategies.
AREAS OF INTEREST
1. There are two compressors are in the building: Devilbliss ™ serves the controls, and the other is for
theater operations.
2. The AHU serves both the building & radio station. Radio station currently does not operate 24/7 but if
the operation changes, it may be better to have a dedicated AHU for station, rather than heat/cool the
whole building.
3. Install a 4-Pipe Fan Coil Unit for the Radio Station. Demo the CV Dual Duct air handling unit and the
constant volume mixing boxes to a Dual Fan, Dual Duct VAV Air Handling Unit and VAV Mixing Boxes
and install digital controls.

ROZELL BUILDING
The Rozell building contains the central heating and
cooling generating equipment for the entire
campus.
HEATING PLANT
There are five high-pressure steam boilers located
in the central steam plant at Eastern Washington
University. All are capable of firing off of natural
gas and No. 2 fuel-oil. Boiler #1 is rated at 56,000
lbs/hr, Boiler #2 at 25,000 lbs/hr, Boiler #3 at
25,000 lbs/hr, Boiler #4 at 47,000 lbs/hr, and
Boiler #5 at 89,000 lbs/hr. With the exception of
boiler #5, which was installed and fired in 2003, all
of the boilers are more than fifty years old—and
some are more than sixty years old. Boiler #3
broke down three years ago and it remains out of
service to this day. Boilers #1, #3, and #5 have
boiler feedwater economizers installed in their exhaust stack; Boilers #2 and #4 do not. Typically during the
cooling season, only Boiler #2 operates. Boilers #1 and #4 operate during the shoulder seasons and Boiler #5
operates during the peak months of the heating season. Boiler #5 is the only boiler with a low-nitrogen-oxide
burner; the other boilers’ burners should be upgraded to low-NOx burners as well.
Condensate from the campus is pumped into a large tank in the lower level of the Rozell Building’s boiler
room. If required, make-up water is introduced into the system with the campus condensate. From this tank
the water is then pumped to the De-aerator (DA) tank which is located in the boiler room. From the DA tank
the water is then pumped into the respective boilers based on their need, using the dedicated floor-mounted
feedwater pumps. These pumps are capable of pumping the water into the boilers directly, as in the case of
Boiler #2 or Boiler #4 or into the economizers on Boilers #1 and #5. The boiler feedwater being pumped into
the stack economizers must be under an elevated pressure in order to ensure it does not flash off to steam in
the heat exchanger in the exhaust stack. After taking the heat out of the exhaust stack gases, the feedwater
is then introduced into the boiler.
The facility has three 50-horsepower boiler feedwater pumps, all taken from another system. These well-used
pumps have had several seal and impeller failures, sometimes simultaneously, placing the entire feedwater
load on the steam turbine pump—which can only operate when the minimum load is 20,000 lb/hr or greater,
thus risking complete steam plant shut down.
The methodology in which chemicals are introduced into the steam system should be analyzed as well, as this
may produce significant savings in both energy and chemicals.
COOLING PLANT
The University’s cooling system is comprised of three 1,000-ton, water-cooled Carrier centrifugal chillers and
two 500-ton water-cooled Carrier Centrifugal chillers, producing a total cooling capacity of 4,000 tons. Each
chiller has a dedicated primary chilled water pump and condenser water pump, as well as a dedicated cooling
tower. All of the towers are induced-draft, open-circuit Marley cooling towers. The three 1,000-ton towers are
REDUCING SCOPE 1 & 2 EMISSIONS
EASTERN WASHINGTON UNIVERSITY | ENERGY EFFICIENCY & SUSTAINABILITY REPORT
Reducing Scope 1 & 2 Emissions
sized to deliver 85 degree water to the chillers, while the 500-ton towers were originally sized to deliver the
water at 85 degrees as well. Due to age, the 500-ton towers can deliver only 88-90 degree water during the
peak of the cooling season.
The chilled water distribution system is a primary/secondary, variable-volume pumping system with tertiary
pumps at the building or load source. There are three secondary system pumps that serve the campus loop.
They are brought online/ offline based on being able to maintain 14 inches Water Column (WC) between the
supply and return lines. Only one of the secondary pumps is controlled with a variable-frequency drive, while
the other two have two-speed motors. For some reason, the tertiary pumps in the buildings or at the coils are
only turned on when the outdoor air temperature reaches 85 to 90 degrees. Peak-season cooling is between
2,300 and 2,400 tons.
There are two plate-and-frame heat exchangers for free cooling. The older unit is approximately fourteen
years old and has 300 tons of cooling capacity. The newer unit, installed by McKinstry in 2003, has a cooling
capacity of 200 tons. Each unit has a one-degree approach.
AIR DISTRIBUTION SYSTEM
Rozell’s office area is served by a variable-volume air handler with VAV boxes and hot water reheat coils. The
unit is mounted on the roof of next to the cooling towers. Other constant-volume variable-temperature air
handling units serve the boiler room and the refrigeration mechanical room.

Detailed Report
EASTERN WASHINGTON UNIVERSITY/ROZELL CENTRAL PLANT BUILDING
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT – AUGUST 2010
OVERVIEW
The Rozell Central Heating and Cooling Plant building
is a support services facility of Eastern Washington
University and is located on the northern side of the
EWU campus in Cheney Washington. A preliminary
energy audit was conducted on all of the systems in
Rozell.
ROZELL CENTRAL PLANT BUILDING
The Rozell Central Plant Building is a two-story brick
building which was built in 1970. The latest upgrades
and renovations were completed in the 2002 – 2003
time frame. This is a 56,000 square foot facility which
houses the Campus’s Central Steam Plant and the
central chilled water plant. It also houses the
university’s Construction and Planning Department, as
well as the Director of Maintenance and the energy
management office and Facilities Information
Technology offices. Facilities I.T. is responsible for
architecting and administering the support systems and server farm for all of Facilities and Planning. The
Central Heating and Cooling Plants provide high pressure steam and chilled water to the Utility Tunnel System
that basically brings the steam and chilled water to most buildings on the EWU campus. Condensate return is
also brought back from the buildings on campus through the utility tunnel system.
PREVIOUS ENERGY RETROFITS
McKinstry has previously completed retrofits of the Rozell Central Plant building in 2003. At that time
McKinstry installed a new 1,000 Ton Open Circuit, Induced Draft Marley Cooling Tower and its associated
condenser water pump. McKinstry installed a 200 Ton Plate and Frame heat exchanger, and associated
pumps, as well as automating the chilled water plant with Delta Digital Controls. McKinstry also installed a
small cooling only fan coil for the UPS systems in the lower level mechanical room. Prior to that, a lighting
retrofit was done throughout the building that saw all of the T12 fluorescent lamps and standard ballasts
getting retrofitted with T8 Lamps and electronic ballast. The only area of Rozell that still has an opportunity to
save energy on lighting is in the Boiler room itself, with the high bay lighting fixtures.
HEATING SYSTEM
There are (5) five high pressure steam boilers located in the central steam plant at EWU. All are capable of
firing off of natural gas and No. 2 fuel-oil. Boiler #1 is rated at 56,000 lbs/hr, Boiler #2 at 25,000 lbs/hr,
Boiler #3 at 25,000 lbs/hr, Boiler #4 at 47,000 lbs/hr, and Boiler #5 at 89,000. With the exception of boiler
#5 which was installed and fired in 2003, all of the boilers range in age from 50 plus years old to 60 plus
years old. Three years ago, Boiler #3 had significant issues which caused it to shut down and to this day it has
not been brought back on line. Boilers #1, #3, and #5 have boiler feedwater economizers installed in their
exhaust stack; boilers #2 and #4 do not. Typically during the cooling season, only boiler #2 operates. Boilers
#1 and #4 operate during the shoulder seasons and boiler #5 operates during the peak months of the heating
season. Boiler #5 is the only boiler with a Low NOx Burner. The other 4 boilers would be excellent candidates
to have their burners swapped out with Low NOx Burners.
REDUCING SCOPE 1 & 2 EMISSIONS
EASTERN WASHINGTON UNIVERSITY | ENERGY EFFICIENCY & SUSTAINABILITY REPORT
Reducing Scope 1 & 2 Emissions
Condensate from around the campus is pumped into a large tank in the lower level of the Rozell Building’s
boiler room. If required, make up water is introduced into the system with the campus condensate. From this
tank the water is then pumped up to the Deaerator tank which is located in the boiler room. From the DA tank
the water is then pumped into the respective boilers based on their need using the dedicated floor mounted
boiler feedwater pumps. These pumps are capable of pumping the water into the boilers directly, as in the
case of Boiler #2 or Boiler #4 or into the economizers on Boilers #1 and #5. The boiler feedwater being
pumped into the stack economizers must be under an elevated pressure in order to ensure is doesn’t flash off
to steam in the heat exchanger in the exhaust stack. After taking the heat out of the exhaust stack gases, the
feedwater is then introduced into the boiler.
Currently Eastern Washington University has (3) three 50 HP boiler feedwater pumps, these pumps were
taken from another system to be used for the feedwater system. As a result of making use of these (3) three
used pumps, there have been several seal and impeller failures which has resulted in simultaneous outages in
all (3) three pumps. This has placed the entire feedwater load on the steam turbine pump, a pump that can
only operate when the minimum load is 20,000 lb/hr or greater, thus placing the steam plant at risk of being
completely shut down.
The way chemical is introduced into the steam system should be analyzed. It has been McKinstry’s experience
that this usually leads to significant savings from an energy perspective as well as a capital dollars
expenditure on less chemicals.
COOLING SYSTEM
The university’s cooling system is comprised of (3) 1,000 ton water cooled Carrier centrifugal chillers, and (2)
500 ton water cooled Carrier Centrifugal chillers. In all there is a cooling capacity of 4,000 tons. Each chiller
has a dedicated primary chilled water pump and condenser water pump, as well as a dedicated cooling tower.
All of the towers are induced draft, open circuit Marley cooling towers. The three 1,000 ton towers are sized to
deliver 85 degree water to the chillers, while the (2) 500 ton towers were originally sized to deliver the water
at 85 degrees as well. The age of the (2) 500 ton towers and their ability to reject heat to the atmosphere has
deteriorated through the years and are only able to deliver 88 to 90 degree water during the peak of the
cooling season.
The chilled water distribution system is a primary / secondary variable volume pumping system with tertiary
pumps out at the building or load source. There are three secondary system pumps that serve the campus
loop. They are brought on / off line based on being able to maintain 14 in. WC between the supply and return
lines. Only one of the secondary pumps is controlled with a VFD, while the other 2 are 2-speed motors. For
some reason, the tertiary pumps in the buildings or at the coils are only turned on when the outdoor air
temperature reaches 85 to 90 degrees.
According to the Plant Supervisor, Kevin Beckwith, told McKinstry that the largest cooling load that the plant
personnel see during the peak of the cooling season is approximately between 2,300 tons and 2,400 tons.
There are 2 plate and frame heat exchangers for free cooling. The older of the 2 is approximately 14 years old
and has 300 tons of cooling capacity while the newer of the 2 that McKinstry installed in 2003, has a cooling
capacity of 200 tons. Each plate and frame heat exchanger has a 1 degree approach.
AIR DISTRIBUTION SYSTEM
The ventilation system serving the office area of Rozell is comprised of a variable volume air handling unit
with VAV boxes with hot water reheat coils. This unit is mounted on the roof of the Rozell Building next to the
cooling towers.

SCIENCE HALL
It is McKinstry’s opinion that the re-model and retrofit of Science
Hall’s HVAC systems could potentially provide the most significant
energy savings of any project on campus. This building is due to be
remodeled after the new
Science 1 and Science 2 Buildings have been built.
Three large, constant-volume, terminal-reheat air handing units
introduce 100% outdoor air to the building. Each unit has a runaround heat recovery coil, a face/bypass low pressure steam coil, a
chilled water coil and humidifiers. They serve a wide variety of areas such as classrooms, laboratories, offices,
and administrative areas. This building has a general exhaust system and fume hood exhaust systems. The
balance between the three systems is controlled by the Staeffa digital control and pneumatic controls.
Two of the three AHUs are remotely located in below grade mechanical rooms. Due to how the outdoor air is
introduced to these AHUs, the pre-heat coils have frozen up before on more than one occasion. It is
McKinstry’s recommendation that the outdoor air intakes be addressed.

EASTERN WASHINGTON UNIVERSITY/SCIENCE BUILDING
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT – AUGUST 2010
OVERVIEW
The Science Building is the largest academic facility on the Eastern
Washington University and is located right on Washington St. in the
center of the EWU campus in Cheney Washington. A preliminary
energy audit was conducted on the building in August of 2010 by
McKinstry.
SCIENCE BUILDING
The Science Building is two-story concrete masonry building which
was built in 1962 with renovations made in 1994. This is a 148,000
square foot facility which houses most of the science departments on
campus and includes laboratories, classrooms and faculty offices. It is in the shape of square with an open
courtyard in the center. The science departments in this building are chemistry, biology, geology, physics and
natural and environmental science. The facility has a greenhouse, planetarium and a, Vivarium.
PREVIOUS ENERGY RETROFITS
In 2003, McKinstry installed replaced vari-cones on many of the air handlers and installed variable frequency
drives. Prior to 2003, a lighting retrofit was done in the 2000 – 2001 time frame.
HEATING SYSTEM
The heating system serving the theater is provided by the Campus Central Steam Plant. The steam pressure
coming into the building is 110 psi and is reduced twice in the existing steam station. First the steam pressure
is reduced to 30 psi steam at the steam station and then further reduced to 12 psi. The medium pressure
steam is used for heating the domestic water, while the low pressure steam is used for the low pressure
steam pre-heat coil in the multi-zone air handling unit, and is used for heating hot water through a steam /
water converter for the reheat coils located throughout the building.
COOLING SYSTEM
The cooling system uses chilled water from the central chilled water plant in Rozell.
AIR DISTRIBUTION SYSTEM
The ventilation systems in the Science Building are comprised of (3) large constant volume terminal reheat air
handing units that introduce 100% outdoor air to the building. Each unit has a run around heat recovery coil,
a face/bypass low pressure steam coil, a chilled water coil and humidifiers. They serve a wide variety of areas
such as classrooms, laboratories, offices, and administrative areas. This building has a general exhaust
systems and fume hood exhaust systems. The balance between the three systems is controlled by the Staeffa
digital control/ and pneumatic controls.
There are issues with the pre-heat coils freezing up that need to be addressed. 2 of the supply air handlers
are in their respective underground mechanical rooms that are only connected to the science building through
the utility tunnels. The outdoor air vents have a lot of tree dirt and snow that accumulates at the bottom of
the outdoor air intakes into the air handlers. This blockage deprives the coils to work appropriately and thus
causes some freezing problems.

SEQUENCE OF OPERATIONS
1. The ventilation systems in the Science Building are comprised of (3) large constant volume terminal
reheat air handing units that introduce 100% outdoor air to the building. Each unit has a run around
heat recovery coil, a face/bypass low pressure steam coil, a chilled water coil and humidifiers. They
serve a wide variety of areas such as classrooms, laboratories, and offices.
AREAS OF INTEREST
1. This building presents the university with its largest source of potential energy savings. This building
consumes more energy than any other building on campus. The potential retrofits that McKinstry
would recommend is momentarily limited due to the eventual plans for EWU to build Science 1 and
Science 2 in the next 4 to 6 years.
2. Create a different design for the outdoor air intake for the (2) AHUs located in their respective
underground mechanical rooms.

EASTERN WASHINGTON UNIVERSITY/SUTTON HALL
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT AUGUST 18, 2010.
OVERVIEW
Sutton Hall of Eastern Washington University is
one of the six historic buildings in the EWU
Historic District of the EWU campus in Cheney
Washington. The EWU Historic District, as it is
commonly known, was the first university historic
district in the state to receive National Register
designation. A preliminary energy audit was
conducted on August 18, 2010 by McKinstry.
SUTTON HALL
Sutton Hall is a 32,000 square foot three-story red
and brown brick structure with concrete
foundation and flat roof which was completed in
1923. It was originally the first men’s dormitory
on the campus. Its foot print is that of a wide letter "H", 133 feet long across the east facade with two 111
foot wings. Around 1978 it ceased operation as a dormitory and it was completely remodeled in 2001 as an
administrative building.
The new HVAC system was designed for a wide open floor plan to accommodate a cubicle office environment.
Over the past 10 years however, there have been many walls and partitions that have been constructed for
office space, which went against the intent of the original HVAC design. The Building Maintenance department
on campus has received many comfort complaints from the occupants complaining of their respective zones
being to warm or to cold. There are some that the main AHU serving this building is undersized.
PREVIOUS ENERGY RETROFITS
In 2003, McKinstry replaced the Vari-cones on the supply and return fans and replaced them with variable
frequency drives and connected them to the existing Staeffa Digital Controls system.
HEATING SYSTEM
Heating in this building is provided by the Rozell Central steam plant. Steam is introduced to the building at
110 psi and then reduced to 35 psi and then further to 15 psi. The 35 psi steam is utilized in the domestic hot
water system while the low pressure steam is used in the pre-heat coil in the main air handling unit and a skid
mounted steam/water converter, where the heated water gets circulated to the baseboard fin tube radiators
located around the perimeter of the building on all floors.
COOLING SYSTEM
Cooling is provided to Sutton Hall from the central chilled water plant. The chilled water is used by the main
air handling unit’s chilled water coil.
AIR DISTRIBUTION SYSTEM
The ventilation system in Sutton Hall is comprised of a central variable air volume air handling unit located in
the basement mechanical room that serves variable air volume boxes. The air handler has a dedicated st5eam
pre-heat coil and a chilled water coil, pre-filters, and final filters, and a dedicated return fan. In 2003, variable
frequency drives were installed and mapped into the digital control system, The VFDs, in conjunction with the
REDUCING SCOPE 1 & 2 EMISSIONS

Reducing Scope 1 & 2 Emissions
digital controls system, now control the volume of air. McKinstry will evaluate whether or not this air handler
is properly sized. The building’s HVAC systems are controlled with Staeffa Digital Controls.
SEQUENCE OF OPERATIONS
1. Due to the design of the ventilation system the air handler struggles with the start up loads in the
morning which translates to longer operating hours.
2. This air handler struggles with economizer operation.
3. No supply air reset strategy.
4. No Hot water reset strategy in place.
AREAS OF INTEREST

THEATER HALL
The HVAC system consists of two air handling units
AHU-1 (labeled AH-D-1) serves four zones in the
Auditorium. It has a steam pre-heat coil and a chilled
water coil for cooling (listed at 21,000 [email protected] 3” SP
with 1130 rpm). AHU-2 serves the building beyond
the Auditorium. It is a constant-volume, terminalreheat air handling unit with a dedicated return fan. It
does not have a pre-heat coil, relying almost
exclusively on return air mixing with outdoor air.
Final air tempering is performed at the zonal level by
the terminal boxes. Both air handlers rely on the
building’s original pneumatic controls. This equipment
has outlived its rated useful service life and should be
considered to be replaced with energy efficient HVAC
systems. These AHUs are limited in their energy
saving capabilities.
Note: excessive sound attenuation throughout both ventilation systems presents a great opportunity to decrease pressure
drop.

EASTERN WASHINGTON UNIVERSITY/THEATER-DRAMA BUILDING
FIELD NOTES FROM PRELIMINARY ENERGY AUDIT AUGUST 4, 2010
OVERVIEW
The Fine Arts Complex of the Eastern Washington
University is comprised of several buildings: Art,
Music, Theater, Radio and TV, and Communications
on the south side of the EWU campus in Cheney
Washington. McKinstry has not previously
completed retrofits of this complex. A preliminary
energy audit was conducted on August 4, 2010 by
McKinstry.
THE THEATER BUILDING
The Theater building is part of the Fine Arts
Complex which was completed in 1971. The facility
consists of classrooms, offices and a performance
theater. This is a three story 36,000 sf concrete
masonry block building with red face brick.
Windows are double pane. The occupancy ratio is
50 faculty/staff members and 400 students.
Operating hours are 8:30AM to 8:00 pm though out
the year. The occupancy tapers off in the summer
pretty drastically as well as weekends. Performances are held periodically throughout the year in the
evenings.
PREVIOUS ENERGY RETROFITS
No previous mechanical retrofit work was completed by McKinstry in this facility. A lighting retrofit was done in
the 2000 to 2001 time frame.
HEATING SYSTEM
The heating system serving the theater is provided by the Campus Central Steam Plant. The steam pressure
coming into the building is 110 psi and is reduced twice in the existing steam station. First the steam pressure
is reduced to 22 psi steam at the steam station and then further reduced to 12 psi. The medium pressure
steam is used for heating the domestic water, while the low pressure steam is used for the low pressure
steam pre-heat coil in the multi-zone air handling unit, and is used for heating hot water through a steam /
water converter for the reheat coils located throughout the building.
COOLING SYSTEM
Cooling in this building is provided by the central chilled water plant in Rozell.
AIR DISTRIBUTION SYSTEM
The HVAC system consists of two air handler units. AH1 (Labeled AH-D-1) is a Multi-zone unit which serves 4
zones. This unit has a steam pre-heat coil and a chilled water coil for cooling (AH1 is listed at 21,000 [email protected]
3” SP with 1130 rpm). This unit serves the auditorium.
AH 2 is a constant volume, terminal reheat air handling unit with a dedicated return fan. This air handler does
not have a pre-heat coil and relies almost exclusively on the return air mixing with the outdoor air. Final
REDUCING SCOPE 1 & 2 EMISSIONS
EASTERN WASHINGTON UNIVERSITY | ENERGY EFFICIENCY & SUSTAINABILITY REPORT
Reducing Scope 1 & 2 Emissions
tempering of the air is performed at the zonal level by the terminal boxes. This air handler serves the rest of
the building outside of the auditorium. Both air handlers are controlled old pneumatic controls.
One item to note was the excessive sound attenuation throughout both ventilation systems. This could present
a great opportunity to decrease the pressure drop across both ventilation systems if addressed properly.
SEQUENCE OF OPERATIONS
1. Both AHUs operate 24/7.
2. Very limited in energy management capabilities.
AREAS OF FURTHER INVESTIGATION
1. Convert both ventilation systems to VAV systems. Examine feasibility of using fan walls to control the
noise levels throughout the building. Install new VAV boxes with factory mounted digital controls. Install a
heating hot water coil in AHU#2.
2. Lighting system retrofit in the stage area of the auditorium.
3. The steam station needs to have certain components replaced.

PEDESTRIAN AND WALKABILITY ANALYSIS
Current Condition: Traffic crossings are hazardous, public transportation and established bicycle routes are
limited, and motor vehicle traffic volume is high due to the nature of campus location from urban hub.
However, high-and-medium-traffic walks have notable lighting or accessibility issues.
RECOMMENDATIONS:
• Improve transportation and pedestrian linkages.
• Analyze areas of conflict, especially those along Washington Street identified in plan D-1.
• Improve safety of high or medium use crosswalks over major streets. Add street striping, signage,
lighting, and ADA ramps.
• Improve transportation routes to include multiple stops around campus, especially at key locations such
as the visitors center and other highly used areas.
• Consider a van pool and/or ride sharing program, specifying locations for pick-up and drop-off.
• In future development, prevent further conflict between high-traffic motor vehicle and pedestrian areas.
• Refine City of Cheney’s bicycle routes plan. Consider adding more bike racks, showers for bike users, and
a bike share program where students can borrow or rent bicycles for an allotted amount of time.
• Address areas where multiple problems occur within the same vicinity as noted on sheet D-1.
• In accordance with the University’s developing accessibility plan, consider ADA problems and areas of low
light levels along heavily used walks as noted on sheet D-1.
• Plan to address issues in areas of highest use or future development first.
• Offer incentives to use alternative transportation, especially for students and faculty who are traveling to
and from Spokane, or over ten miles.
• Establish a fleet of campus owned electric cars to replace other campus vehicles.

Current Condition: Currently many high traffic crossings are safety hazards; inadequate public transportation
causing high traffic volumes; No established bicycle routes and high motor vehicle volumes; High and medium
traffic walks have notable lighting or accessibility issues; No campus owned electric vehicles.
RECOMMENDATION OR PROPOSED CONDITION
Improve transportation and pedestrian linkages. Analyze areas of conflict, especially those along Washington
Street identified in plan D-1. Crossings of high or medium use walks over major streets such as Washington,
without adequate safety features need to be modified to reduce conflict. Improve crossings with street
striping, signage, lighting, and ADA ramps. Improve transportation routes to include multiple stops around
campus. Include stops at key locations such as visitors center highly used areas. Consider implementing a van
pool and/or ride sharing program and select preferred locations for pick up and drop off. Consider a separate
campus bus system as campus expands. Refine City of Cheney’s bicycle routes plan. Plan carefully as to not
cause conflict between high traffic motor vehicle and pedestrian areas. Consider the implementation more
bike racks, showers for bike users, and a bike share program where students can borrow or rent bicycles for
an allotted amount of time. Address areas where multiple problems occur within the same vicinity as noted

A. STORMWATER
Agricultural Property Practices
Current Condition: The Eastern Washington University campus includes approximately 200 acres of cultivated
farmland on the western campus boundary, no plans for which appear in the current campus master plan
(May 2005). Construction of athletic fields has encroached on the area, creating steep cut slopes. The
property drains towards the campus and adjacent neighborhoods, creating potential for sedimentation and
drainage facility damage in seasonal rains or during construction.
RECOMMENDATIONS:
1. Manage future development of this property to include careful evaluation of grading and erosion control,
as well as using topography and wind patterns to reduce heating and cooling costs.
2. Implement drainage-basin-level erosion control plans for permanent and temporary construction erosion
control. Carefully select sites for future development and avoid development on steep slopes. Establish or
leave native vegetation undisturbed when possible. Protect storm sewer inlets from sediment.
IMPERVIOUS SURFACES
Current Condition: The Eastern Washington University campus has more than 2.2 million square feet of
building roofs and paved surfaces impervious to precipitation, creating approximately 11,654,000 gallons of
storm water per year, which largely flows into storm drains and into the City of Cheney’s sewage lagoons.
RECOMMENDATIONS:
1. For existing developed areas of campus consider modifications to existing impervious surface and roof
drainage systems to reduce the amount of impervious surface:
• Incorporate pavers as a campus standard for major walkways to reduce storm water runoff.
• Consider green roof systems.
• Modify existing building downspouts to discharge into planting areas, rain gardens or into storm
water reuse facilities.
• Use pervious pavements in parking lots and walkways.
• Reduce street widths as appropriate.
• Increase public transit, bicycle and pedestrian use to reduce requirements for parking lots.
2. Future development: reduce impervious surface areas and impacts of building roofs.
• Require green roof systems and/or installation of solar PV systems on every new roof.
• Require all roof runoff to be utilized on site or connected to a campus wide storm water reuse
system.
• Incorporate storm water forebays that could include infiltration basins, rain gardens or other
treatment facilities prior to discharging roof runoff or storm water into water reuse facilities or storm
drains.
• Install pervious pavements in parking lots and walkways.
• Reduce street widths as appropriate.
• Increase public transit, bicycle and pedestrian use to reduce requirements for parking lots.
• Consider extending the use of pavers to reduce labor costs associated with snow removal.

STORMWATER COLLECTION AND RE-USE
Current Condition: Eastern Washington University has significant opportunities to reuse much of its annual
11.6 million gallons of stormwater and air conditioner condensate. These sources could reduce irrigation
demand, preserving the aquifer to accommodate future campus growth. Retaining and reusing stormwater
would also reduce flooding in utility tunnels, which currently require pumping.
RECOMMENDATIONS:
• Map drainage patterns, groundwater infiltration areas, flood zones and aquifer recharge zones,
paying special attention to drainage from impervious surfaces.
• Establish a plan to store, treat and reuse this storm water along with groundwater and condensate—
possibly in campus landscape irrigation, or in non-potable water uses such as building heating or
toilets.
• When possible, infiltrate water naturally into the aquifer through rain gardens and infiltration swale
systems.
Regularly inspect drain systems for blockages and pollution.

V.CAMPUS TOPOGRAPHY & RUNOFF
Ref. Sheets A.3; B.1; B.2
ROM PROJECT TR.1 – AGRICULTURAL PROPERTY PRACTICES
Current Condition: The EWU campus includes approximately 160 of undeveloped property on the western
campus boundary that is in agricultural use. Farming practices periodically leave the property without
vegetation and fugitive dust from the property is often blown onto campus.
The current campus master plan (May 2005) does not indicate plans for the western property. This area
includes steep slopes and agricultural soils. Construction of athletic fields has encroached on the area and has
resulted in steep cut slopes. The property has numerous existing drainages that have evidence of runoff
toward developed portions of campus and adjacent neighborhoods. There is potential for sedimentation and
damage of drainage facilities due to seasonal runoff or during construction.
RECOMMENDATION OR PROPOSED CONDITION:
1. Management and future development of this property (if desired) should include careful evaluation of
grading and erosion control. The effects of topography on temperature and air flow should be considered
and taken advantage of. Analysis of topography and natural wind patterns should occur in order to take
full advantage of cooling effects or avoid higher heating costs.
2. Implement drainage basin level erosion control plans for permanent and temporary construction erosion
control. Carefully select sites for future development and avoid development on steep slopes. Establish or
leave native vegetation undisturbed when possible. Protect storm sewer inlets from sediment.
Savings: Money and Labor savings from protection of storm drainage facilities; reduced energy costs and
consumption.
V. CAMPUS STORMWATER & DRAINAGE
Ref. Sheets B.1; B.2; C.1
ROM PROJECT SD.1 – STORMWATER REDUCTION
Current Condition: The EWU campus has over 1.1 million square feet of roof tops and another 1.2 million
square feet of parking lots and driveways, with about half that have tree canopy for shade. These roofs and
parking areas are exposed to direct solar radiation resulting in the heat island effect. In addition, the
approximately 2.2 million square feet of building and pavement impervious surface directly results in storm
water runoff that must be disposed of. The storm water from parking and driveways contains numerous
contaminants including oils, heavy metals, fertilizers and sediment. Much of this runoff is discharged to storm
drains without treatment. The storm drainage system apparently discharges to the city of Cheney sewage
lagoons.
The amount of storm water generated over the course of the year is approximately of 11,654,000 gallons of
storm water. (1,100,00sf x 1.42’ precipitation per year = 1,558,333 cu. ft of stormwater or 11,654,649
gallons per year. A portion of this water will be absorbed in the turf areas adjacent to walkways and plazas.
The stormwater that is not absorbed will ultimately be disposed of into the campus storm drain system
without treatment.

EASTERN WASHINGTON UNIVERSITY | ENERGY EFFICIENCY & SUSTAINABILITY REPORT
Efficient & Sustainable Campus Systems
RECOMMENDATION OR PROPOSED CONDITION
1. For existing developed areas of campus consider modifications to existing impervious surface and roof
drainage systems to reduce the amount of impervious surface with:
•
Incorporate pavers as a campus standard for major walkways to reduce storm water runoff.
•
Green roof systems
•
Modify existing building downspouts to discharge into planting areas, rain gardens or into storm
water reuse facilities.
•
Pervious pavements in parking lots and walkways
(Use of pavers as a campus standard contributes to the reduction in runoff.)
o Open cell pavers with grass for overflow parking areas and emergency access.
o Pervious or porous concrete
•
Reduced street widths, size streets appropriately for the amount of traffic.
•
Increase public transit, bicycle and pedestrian use to reduce requirements for parking lots.
2. For future development incorporate the following strategies to reduce the amount of impervious surface
areas and impacts of building roofs. Reduction of impervious surface areas can contribute to the mitigation
storm water and heat gain impacts of new building roofs and paving. Strategies include:
•
Requiring green roof systems and/or installation of solar PV systems on every new roof.
•
Require all roof runoff to be utilized on site or connected to a campus wide storm water reuse
system.
•
Incorporate storm water forebays that could include infiltration basins, rain gardens or other
treatment facilities prior to discharging roof runoff or storm water into water reuse facilities or
storm drains.
•
Install pervious pavements in parking lots and walkways (Continue the use of pavers as a campus
standard to reduce runoff.)
o Open cell pavers with grass for overflow parking areas and emergency access.
o Pervious or porous concrete
•
Reduced street widths, size street appropriately for the amount of traffic.
•
Increase public transit, bicycle and pedestrian use to reduce requirements for parking lots.
•
Consider extending the use of pavers to reduce labor costs associated with snow removal.
Savings: Reduced labor and energy costs and consumption, reduced greenhouse gas emissions, comfort and
health benefits, stormwater quality improvement, reduced use of deicer and salts, reduced heat island effect.
ROM PROJECT SD.2 – STORMWATER COLLECTION AND RE-USE
Current Condition: With 1,558,333 cu.ft. of water (11.6 million gallons) of stormwater, there are significant
opportunities to reuse storm water, ground water, and air conditioner condensate on campus. This reduces
irrigation demand and helps preserve the aquifer, both of which are potential constraints on future campus
growth. Additionally, currently groundwater is intruding into utility tunnels and basements and pumped to
storm water drains.
RECOMMENDATION OR PROPOSED CONDITION:
Additional research and identification of groundwater infiltration areas needs to occur. Identify areas of flood
zone, watersheds, stream corridors, hundred year floodplains, and aquifer recharge zones. Avoid construction
in sensitive areas such as these and consider how to reuse water. Consider storm water that is a result of
impervious areas for each drainage basin outline in Sheet A-3. Establish a plan to store, treat and reuse this
storm water along with groundwater and condensate. Examples of reuse include campus landscape irrigation
and reuse within buildings for necessities such as heating or non-potable water uses such as toilets.
