Applications
Seismic - RSF and RSFP
With changes in building codes and standards, more equipment
is being required to be seismically certified in areas of the
country not commonly thought of as being in seismically
active zones.
The International Building Code (IBC) is designed to provide
model code regulations that safeguard public health and safety
in all U.S. communities. This code is intended to improve the
performance and design of non-structural systems subject
to seismic events.
The State of California, one of the most active seismic areas in
the United
States, has the Office of Statewide Health
Un
Planning
and Development (OSHPD) to regulate the
Pla
P
design
and construction of healthcare facilities to
d
ensure
they are safe and capable of providing
e
services
to the public after a seismic event.
s
OSHPD
developed their own unique certification
O
process
to incorporate the IBC and ASCE testing
p
standards to ensure equipment remains operable
after a seismic event.
Protocols designed for seismic standards:
6
Seismic
Testing Criteria
All Greenheck seismically certified models have been tested using the most severe seismic event that is
found on the Spectral Response Map per IBC Figures 1613.5 (1-2). Our testing is performed under the
worst case scenario using the highest mapped seismic load, highest level occupancy category, worst
case site class, and highest code mandated importance factor, thereby allowing Greenheck’s seismically
certified fans to be used anywhere in the United States under any conditions.
California OSHPD
Test Protocols
The California Office of Statewide Health Planning and Development (OSHPD) requires all certified
models be shake table tested in accordance with ICC ES AC-156, in which the fans are physically
subjected to the same or greater forces than they will see during a seismic event. Subjecting Greenheck
model RSF and RSFP fans to this type of testing ensures the fans will operate without problems after a
seismic event.
OSHPD Certification
No. 0113-10
The OSHPD certification numbers and supporting documents can be viewed on OSHPD’s
website ensuring that the fan has been subjected to and passed rigorous testing standards.
State Licensed
P.E. Calculations
When using the fans in applications which are not covered by California OSHPD standards, Greenheck
models RSF and RSFP have been certified by a third party engineering firm to IBC 2009, 2012 and
ASCE 7-05 standards. These engineers hold professional engineering (P.E.) licenses in all 50 states, so
no matter where your job is located, you are backed by a P.E. signature for your state.
Certified Independent
Third-Party Testing
All Greenheck seismically certified fan models have gone through extensive testing procedures.
Greenheck models RSF and RSFP have been certified to IBC 2009, 2012, ASCE 7-05 and California
OSHPD standards through both engineering calculations and shake table testing of all models by
independent third party engineering firms.
Applications
High Wind and Hurricane - RSF
Greenheck is leading the High Wind Standard for roof top fans and
ventilators. Forceful winds and wind-borne debris are the cause of most
hurricane damage. Hurricane winds start at 75 mph and can exert a
force of 75 pounds per square foot of pressure—or over 900 pounds
on a fan and curb. Forceful winds are not the only problem, wind-borne
debris can also cause detrimental effects to objects and structures.
High winds and extreme forces are the cause of most storm damage.
By analyzing calculations, computer simulations, actual testing, and
other standards—Greenheck developed the High Wind Standard.
U.S. continent
averaged
ed
tornado frequency.
Protocols designed to protect
against wind borne debris and severe wind loads:
Atlantic, Gulf and Pacific history of major hurricane tracks.
Structural
Performance Load
A static load that is 1.5 times the design load (91.5 pounds per square foot of pressure) is applied both
positively and negatively to simulate wind force loads in each direction. Structural Performance per
Dade County Protocol TAS-202 (ASTM-E330).
Miami-Dade County
Test Protocols
Greenheck worked with Miami-Dade County to outline a High Velocity Hurricane Zone standard for
rooftop fans. Model RSF has been certified by an independent third party to the ASTM E-330 Static
Pressure Difference Standard, Florida Building Code Test Protocol TAS-201 (large missile impact),
202 (static pressure difference) and 203 (cyclic pressure) Static Pressure Difference.
Miami-Dade NOA
Numbers
The certifications can be viewed on the Miami-Dade County website under the NOA numbers listed:
Miami-Dade NOA 09-0930.10 for model RSF.
Florida Product
Approval
Florida Product Approval ensures that products which have been approved can be used anywhere in
the State of Florida which are not governed by the Miami-Dade County high wind regulations. More
information can be found on the Florida Building Code website. Florida Product Approval FL13225.2
for model RSF.
State Licensed
P.E. Calculations
Structural calculations performed by a licensed Professional Engineer (P.E.) on model RSF include
Finite Element Analysis (FEA) and a stamped P.E. report of the fans compliance to ASCE 7-05 Minimum
Design Loads for Buildings and Other Structures Standard and the Florida Building Code. The ASCE
7-05 Standard meets the IBC, Florida and Miami-Dade codes. The model has been proven to withstand
wind loads in excess of plus or minus 100 psf.
Computational Fluid
Dynamics (CFD)
All Greenheck high wind models have been analyzed using Computational Fluid Dynamics (CFD).
CFD is computer software designed to simulate the flow of high speed winds over the surface of
objects. The software records the force profile exerted on the fan so it can be utilized
in Finite Element Analysis (FEA).
Finite Element
Analysis (FEA)
Utilizing the results from CFD analysis, Greenheck can accurately predict the stress, strain,
and deflection resulting from high wind loads. Greenheck high wind units have been proven
to withstand 100 psf wind loads through Finite Element Analysis utilizing CFD results.

Typical Installation
Note: In cases where extreme snow depths may be
encountered, an extended base may be required to
raise unit or condensation pans may be required in
ductwork.
Prepunched mounting holes and 21⁄2 inch skirt
to aid in installation.
Ductwork (by others)
Duct adapter (optional) allows ductwork to be
completed prior to setting unit on curb.
Roof curb
Roof opening dimensions can be found with
the dimensional data on the performance
pages.
Service
Filtered supply fans require regular inspection and cleaning (or replacement) of filters to ensure high efficiency and
performance. Both models RSF and RSFP are designed to permit easy access to filters and other components
through the hood cover. Covers also offer complete accessibility of all fan components which can be reached for
inspection, cleaning, and service.
