As a family business in its third generation and a leading international manufacturer of
heating and cooling technology systems, we are committed to the principle of sustainability.
It guides our activities and is securely anchored in our company principles:
"We are committed to fulfilling our economical, ecological and social responsibilities. We
ensure that all our processes are environmentally compatible and encourage the use of
renewable forms of energy. Our aim is to protect the climate and preserve the natural
basis for life. We value and involve ourselves in the scientific, artistic and cultural life of
our society."
Sustainability will be a crucial success factor for every company in the future. It is essential
that we conserve the environment, use resources more efficiently and avoid waste. The
growth needed to maintain our current level of prosperity must be generated from intelligent
value creation in the future, not from the overexploitation of resources, the environment or
the climate.
As the largest consumer of energy in Germany, the heating market offers tremendous
potential for saving energy. Energy is still wasted in 80 percent of buildings because they are
heated with obsolete technology. In addition, up to 40 percent of final energy consumption
could be eliminated in the industrial and manufacturing sectors.
The necessity to protect the climate and save energy has led to a greater use of renewable
energy and particularly energy-efficient products, both in the heating technology sector and
other industries. In cooling and refrigeration technology, the implementation of economical,
environmentally friendly systems can also greatly help to achieve the efficiency objectives
defined by policymakers. Integrated solutions, which comprise heating, cooling, and air
conditioning systems combined with customized energy management, are becoming
increasingly important.
The structural shift towards efficient technologies and renewable energy has given rise to
risks and challenges, opening up great opportunities. The environmental and energy sector is
on its way to becoming a flagship industry. It has the largest rates of growth in investments
and jobs. Climate protection, innovation and economic success go hand-in-hand today. Or, to
put it another way: "Sustainability pays off."
However, sustainability must be actively practiced. Therefore, the current Sustainability
Report of the Viessmann Group provides information about our strategic approach to
sustainability and the individual steps we are taking to implement our concepts.
This report has been drawn up for our most important stakeholders: our customers, our
employees, suppliers, policymakers and public administrations, the media, organizations
and associations, as well as the general public. Together with these partners, we want to
make sure that sustainability continues to be a guiding principle for our business activities in
the future. Therefore, we are looking forward to constructive discussions and a cooperative
dialog with all groups in society.
Prof. Dr. Martin Viessmann
Balancing ecology, economy and
social responsibility
Climate change and the scarcity of natural resources are the major challenges of our
times. Sustainable development is becoming increasingly important in all areas of life.
Preserving the Earth was called for as early as
in the Bible. But the concept of sustainability
as we know it today was not established until
the 18th century. At that time, Europe was
on the edge of a resource collapse: The main
resource of that era, wood, was becoming
scarce. Trees were cut down to build homes
and ships or they were burned for heating. It
was not until the very existence of large parts
of the population was threatened by these
practices that people began to consider how
they could use the forest without ruining it.
Greatest challenge for mankind
Today, we are living in a time when natural
resources are becoming increasingly scarce.
This is most apparent in the dwindling reserves
of fossil fuels, the consumption of which has
doubled since 1970. It will in fact triple by 2030
and, due to the resulting emissions, have a
serious impact on the climate. Establishing
an environmentally compatible and resource
efficient as well as commercially viable energy
supply for the future is more important than
ever before.
This question embodies the essence of
sustainability as defined 200 years later by
the Brundtland Commission: how to meet the
needs of the present without compromising
the ability of future generations to meet their
own needs. In this sense, sustainability is an
intergenerational contract about economic,
ecological and social fairness. These three
dimensions of sustainability do not stand alone:
They make up the three sides of a triangle,
the geometric archetype that symbolizes
sustainability, and are contingent on one
However, the often-cited transition to a
sustainable energy era based on 100 percent
renewable energy is not done easily. In
Germany, fossil fuel sources account for nearly
90 percent of the energy supply. In the long
run, the theoretical potential of renewable
energy will not be enough to meet the current
level of energy demand.
A well-balanced mix of all available resources is
required to cover the remaining demand. This
ranges from the efficient use of fossil fuels,
solar energy, wind, geothermal energy through
to producing energy with biomass. The very
basis of life for future generations is at stake

Sustainable energy era – A challenge and
an opportunity
The EU member states, however, have set for
themselves concrete and ambitious goals. Until
2020, energy consumption is to be reduced by
27 percent, the share of renewable energies is
to be increased to 27 percent and CO2 emissions are to be decreased by 40 percent.
Achieving these objectives will require huge
efforts from some countries. So far, only Italy,
Malta, Sweden, and Cyprus have fulfilled their
obligations to report to the EU Commission on
how they plan to meet their energy-efficiency
targets on time.
Germany has now developed specific
measures for this purpose – albeit with some
delay – which include improvements of the
political framework: the National Plan of Action
for Energy Efficiency (NAPE) and the Climate
Protection Action Program. The NAPE
encompasses the most important measures
for the heating market:

German development bank (KfW) program
and the market incentive program (MAP)

UN climate conferences largely
unsuccessful so far
Policy at the global level has not yet adequately
dealt with the challenges of climate protection
and a sustainable energy supply. Twenty years
after the first United Nations Conference on
Sustainable Development, the international
community has committed itself to
establishing a green economy, but no concrete
targets have been agreed upon, even at the
"Rio 20+" follow-up conference.
The same holds true for the Kyoto Protocol.
Although policymakers are expected to decide
on a follow-up regulation at the World Climate
Conference at the end of 2015 in Paris, the
UN does not anticipate a binding agreement to
take effect before 2020.

particular those generated by the energy
economy, as well as by industry, households,
and transport.
Energy consumption must decrease by
40 percent
Ultimately, the sustainable energy era will
only be possible if we succeed in quickly and
effectively reducing how much energy we
waste. Nearly 40 percent of current energy
consumption could be eliminated by improving
efficiency. In this sense, efficiency is our most
important resource.
The heating sector offers favorable conditions
for the consistent translation of the political
twin strategy. In Germany, approximately
75 percent of all houses were built before the
first Heat Insulation Ordinance of 1977 and
have hardly been insulated since. At least
75 percent of the 20 million heating systems
in Germany need to be modernized. Heating
systems are only replaced after 25 years on
average. According to calculations by experts,
at least 30 percent more energy is used than
necessary. The current rate of modernization
has to increase more than fourfold to bring
energy systems in existing buildings
completely up-to-date by 2020.
More than 30 percent of fossil fuels could
be conserved in the heating sector if all the
energy systems of existing buildings were
modernized. This figure corresponds to twelve
percent of total energy consumption and is
significantly higher than the share of nuclear
power in the energy mix (7.6 percent).
In order to achieve the two-degree
goal, CO2 emissions must be
reduced as soon as possible.

Leading-edge technology that saves valuable resources and thus contributes to
preserving the environment for ourselves and for future generations.
Vitodens 300-W
Vitoladens 300-C
Viessmann offers a comprehensive program
of innovative heating, cooling, and ventilation
systems which sets benchmarks in terms of
Top marks from consumer organization
"Stiftung Warentest"
These characteristics have also been verified
in comparison tests conducted by the German
consumer organization Stiftung Warentest, in
which Viessmann products outperform the
competition and finish in first place on a regular
basis. For its special "Saving energy" issue
published in 2012, Stiftung Warentest took into
consideration the further development that
has taken place at all manufacturers since the
previous round of tests. The results of these
comparisons impressively confirmed Viessmann
heating systems as winners.
The heating market holds the key to the
success of the sustainable energy era. To
achieve this goal, policymakers are calling for
essentially all buildings to be CO2- and energyneutral in the future. With its comprehensive
program, Viessmann supplies the necessary
technology to achieve this, including the right
system solution for every demand – wallmounted or floor-standing, modular,
sustainable, and cost-effective. Areas of
application include single-family and two-family
homes, large residential buildings, commerce/
industry and local heating networks.
It does not matter whether the system is
installed in a new construction or in the course
of modernization. Viessmann develops and
produces innovative heating systems that stand
for top quality, energy efficiency and durability.
Test winner in the category "Gas
Condensing Boilers"
In the test of gas condensing boilers for
example, Viessmann’s Vitodens 300-W came in
first place with an overall rating of "Good" (1.7).
The current Vitodens 300-W features a number
of improvements compared to its predecessor
that underwent testing in 2010. An extended
modulation range and automatic flow balancing
have increased efficiency. Operation is even
more convenient thanks to new radio remote
controls and mobile remote control via iPhone,
iPad or iPod Touch.
Vitosol 200-F, Vitocell 340-M
One of the best oil boilers in the test
As "one of the best oil boilers in the test", the
Viessmann Vitoladens 300-C was given an
overall score of "Good" (1.6) in Stiftung Warentest's current ranking. It therefore occupies a
top spot among the ten oil condensing boilers
ranked by the test. Like all Viessmann
boilers, the Vitoladens 300-C now comes with
new Vitotronic control including a large lighted
graphics-capable display to make it even easier
to operate.
Overall score of "Good" for solar power
In the current test, the Viessmann solar power
system for combined auxiliary heating and DHW
generation was awarded one of the top spots
with an overall score of "Good" (1.8). Comprising
six Vitosol 200-F flat-plate collectors, a
multi-mode Vitocell 340-M combination
cylinder, and a Vitosolic 200 solar control unit,
the solar power system was even rated "Very
good" in the individual assessment of energy
efficiency and DHW heating convenience.
4 Products and Processes

Market launch of new battery technologies
Relaunch of Smart Home systems
The best of several technologies: Hybrid
Condensing technology continues to play a
dominant role on the German and many other
European heating technology markets. The
essential benefits of condensing boilers are
that they are compact, reliable and lowmaintenance units, which are characterized
by economical fuel consumption, clean
combustion and a quiet operating mode.
The Vitocaldens 222-F gas hybrid compact
unit intelligently combines the advantages of
condensing technology with the strengths of
a heat pump module.
Vitocaldens 222-F consists of a time-tested
gas-condensing module with a stainless steel
radial heat exchanger and modulating MatriX
cylinder burner, a heat pump module with an
intelligent hydraulic connection to integrate a
modulating external unit and a DHW cylinder
with a capacity of 130 liters. In the past, gas
condensing boilers and heat pumps could only
be installed separately. Combining them into a
single unit reduces the installation outlay and
saves space.
In the summer period, the unit typically
operates using the heat pump module with
low flow temperatures. The integrated
condensing boiler is only used in the case of
peak loads, for example for heating up water
High temperatures are necessary in the
heating system during the colder seasons.
This is when the condensing boiler
demonstrates its benefits. It ensures the
reliable heating of rooms and DHW
generation. The result is that both of the
systems operate under ideal conditions. This
saves energy and reduces the impact on the
Vitocaldens 222-F gas hybrid
compact unit, consisting of an
internal unit with a heat pump
module and a gas condensing boiler
The intelligent energy manager decides which
system needs to run and when. It optimally
uses the strengths of the two technologies,
combining maximum convenience with bestpossible efficiency.
The compact design and simple hydraulic
connection make Vitocaldens 222-F suitable
for both new construction and for
modernizing old buildings. It is therefore
possible to modernize heating systems with a
reasonable financial outlay and limited
construction measures, implementing a
system that combines fossil energies and
renewable energy.
as well as separate external unit.
4 Products and Processes
Fuel cells as innovative CHP solution
To be suitable for single-family homes with
relatively low heat demands, CHP technology
needs to achieve as high an electrical
efficiency as possible and thus produce a
smaller amount of heat when generating
power. Fuel-cell-based CHP systems are a
suitable complement.
Focusing on using less power from the grid
Using self-generated electricity in your own
home reduces the need to acquire expensive
electricity from the public network. By
reducing dependency on power supply
companies, operators will not be hit as hard
by the rise in electricity prices expected in the
Viessmann has developed the Vitovalor 300-P
fuel cell heating unit for implementation in
newly built single- and two-family homes,
redeveloped old buildings with low heat
demands and in passive houses. It was
launched on the market in April 2014.
Fuel cell units serve as decentralized power
generators, operating in smart grids to reduce
demand on the electricity grids. Last but not
least, the environment also benefits from
this technology: Up to 36 percent of primary
energy is saved when heat and power are
generated simultaneously in a fuel cell
compared to conventionally generated
electricity from a power plant.
The unit has been jointly developed with the
Panasonic Corporation. Fired by natural gas,
the PEM (polymer electrolyte membrane) fuel
cell has already been installed in over 50,000
locations in Japan, where it has proven to be a
great success.
High-temperature fuel cell (SOFC)
In addition to the low-temperature fuel cell
Vitovalor 300-P, Viessmann is also jointly
developing a high-temperature fuel cell (solid
oxide fuel cell, SOFC) with its Swiss partner,
Hexis AG, to complete the product program of
micro CHP solutions in the future.
Micro CHP system based on a Stirling
The Vitotwin 300-W micro CHP system
was launched in autumn 2011 and has been
continuously refined ever since. It combines a
free-piston Stirling engine with a highly
efficient gas condensing boiler. The free-piston
Stirling engine operates without a crankshaft
in a hermetically sealed, maintenance-free
system with helium as the working fluid. The
movement of the piston is transformed into
electricity, while the waste heat of the engine
is used to heat living space and generate
domestic hot water. The overall efficiency is
97 percent (HS).
Fuel cell unit
Vitovalor 300-P
Micro CHP units Vitotwin 300-W
and Vitotwin 350-F
With a base thermal output of 5.3 kW, this unit
is perfectly matched to the heat demand of
single- and two-family homes and is especially
well suited for modernization. The Stirling
engine covers the base heat load, ensuring
long runtimes and excellent economy. The
integrated gas condensing boiler with an
output of up to 20 kW is only additionally
activated when the heat demand is higher, for
instance on cold winter days. Long runtimes
ensure high power yield. The electrical output
of the micro CHP is between 0,6 and 1 kW.
Hence, the unit covers the electrical baseload
of a house; surplus electricity is fed into the
electricity grid.
Whether consumed on site or fed into the grid,
in Germany, the electricity thus generated is
generously subsidized by the federal
government’s Combined Heat and Power
Generation Act. Moreover, the Vitotwin 300-W
has an integrated electricity meter and a builtin gas flow meter. In case of higher power
demand, for instance when a washing machine
runs, the Stirling engine can be turned on via
time switch or wireless remote. The heat
generated in parallel is stored in a buffer
cylinder for later use. The range of products
is rounded off by the compact micro CHP unit
Vitotwin 350-F, which has an integrated
heating water buffer cylinder with a capacity of
175 liters.

Gas adsorption heating unit
The gas adsorption heating unit Vitosorp
200-F consists of a zeolite heat pump module
and a gas heating unit. The heat pump module
provides the baseload of building heating with
ambient heat from the ground. The integrated
gas heating unit powers the heat pump
process and covers demand peaks on
particularly cold days. It also fulfills the
function of a booster, providing rapid and
convenient DHW generation.
Vitosorp 200-F consumes up to 40 percent
less energy than traditional gas heating units.
As a pure gas unit, the heat pump module is
not powered by electricity, but by natural gas
or liquid gas.
Vitosorp 200-F, gas adsorption
heating unit, with DHW cylinder
Vitosorp 200-F has been designed to meet
the heat demand of single-family homes. It
operates highly efficiently in new buildings,
in particular. Its use of environmental energy
makes it a particularly sustainable solution.
Indeed, it meets the stricter requirements for
new builds set out in the 2016 German Energy
Saving Ordinance (EnEV). Vitosorp 200-F is
also an efficient solution for modernization
projects, as flow temperatures of up to 75 °C
are possible (recommended < 55 °C).
It is easy to transport and install, saving time
and expense. Thanks to its compact size and
width of only 600 millimeters, the gas
adsorption heat pump easily fits into a
standard kitchen grid (minimum room height
of 2.20 meters). As it generates low operating
noise and is powered by harmless
operating materials – zeolite and water – it can
be installed close to living areas.
Heating with ice – the ice storage
system Vitofriocal provides the
necessary energy
The ice storage system – an alternative
to geothermal probes and collectors
The usual heat sources available for heat
pumps are ambient air, the ground, or
groundwater. The Viessmann ice storage
system Vitofriocal, on the other hand, uses a
heat source that has not been used for brine/
water heat pumps to date.
One or several 10-cubic-meter concrete
cylinders filled with water are buried in the
ground. They are each equipped with a
withdrawal and regenerative heat exchanger.
Using a brine/water heat pump, the energy
released by the water as it is transformed into
ice is used in the ice storage system. The
additional energy yield generated in an ice
storage system with a capacity of some 10 m3
during this transformation phase is the
equivalent of approx. 100 liters of fuel oil.
Special solar air absorbers on the roof collect
heat from the ambient air and solar radiation
and feed it into the cylinder, while additional
heat is directly absorbed by the ice storage
system from the surrounding earth. Even when
the cylinder is freezing, heat still flows from
the ground.
The ice storage system therefore serves as
a full heat source for brine/water heat pumps
when combined with the solar air absorber.
This solution is particularly suitable in areas
where drilling for geothermal probes is not
authorized for environmental reasons or is
considered to be too expensive.
Cooling with the Vitofriocal ice storage
In summer, the ice storage system can be
used to naturally cool rooms. For this purpose,
it is completely frozen at the end of the heating
season by interrupting the regeneration of the
cylinder using the heat source management
system. The ice formed in this process is
therefore available as a natural source of cold.
Heat is withdrawn from the heating system
using the withdrawal heat exchanger and fed
into the ice storage system. This causes the
ice to melt and heat up the water. The heat
created during passive cooling is stored in the
ice storage system and is available as energy
both for DHW generation and for heating
purposes at the beginning of the heating
season. Ice storage systems can be
implemented with all of the Vitocal brine/water
heat pumps.
Innovative heat source for brine/
water heat pumps: The Vitofriocal
ice storage system can be used
with all of the Vitocal brine/water
heat pumps.

Bioenergy villages – sustainable energy
in rural areas
Bioenergy villages will play a key role in the
success of the sustainable energy era.
Households in these villages are provided
with heat by a local heating network, which
is fed by an energy center. Resources such
as biogas produced locally from agricultural
waste or wood from sustainable forestry are
used. In this sense, every bioenergy village is
a strategic sustainability project.
Viessmann is a competent partner
for the development and the construction of bioenergy villages.

bioenergy village supplied 100 percent with
renewable energy was founded in Wettesingen near Kassel, Germany. In both cases,
Viessmann not only supplied the system
technology. The company also provided
assistance with the project from the initial
idea to actual implementation.
Etanomics – integrated energy concepts for
industry and the manufacturing sector
Due to long-term rises in energy prices, companies are increasingly focusing on the
highest possible energy efficiency and the best possible cost structure.
Annual energy consumption is approximately
2,500 TWh in Germany. The manufacturing
sector and industry account for about onethird of this consumption. The Federal Ministry
of the Environment has calculated that
40 percent of this could be eliminated by the
year 2020 by modernizing energy systems.
This is the equivalent of EUR 19 billion.
However, the long-term rise in energy prices is
not the only cost factor for the manufacturing
sector and industry. In addition, according to
the German Renewable Energies Act (EEG),
only companies that have a certified energy
and environmental management system can
benefit from tax breaks. For this reason, it is
essential that companies strive to maximize
energy efficiency and optimize their cost
Wood can be used to generate power as well as heat.
Viessmann is pleased to share the expertise in
energy efficiency and management obtained
in its strategic sustainability project with other
industrial companies and SMEs. For this
purpose, Viessmann founded Etanomics
Service GmbH. Etanomics develops and
implements integrated energy concepts for
the industry and the manufacturing sector
as well as for services such as the hotel and
catering industry.

New wall-mounted gas boiler production in Turkey
With an investment volume of several tens of millions, Viessmann constructed a new plant
in Manisa (Turkey) for the production of wall-mounted gas boilers.
Viessmann has been doing business in Turkey
for more than 20 years. A Turkish Viessmann
sales subsidiary was founded as early as
1994, and has been very successful on the
market ever since. The company now has ten
sales offices throughout the country. The
positive development of the company in
Turkey and the steady growth of the sales
organization there were the main reasons for
investing in the construction of the new plant.
This makes Viessmann a local producer.
Sustainable building concept
The Manisa plant meets the latest standards
of sustainable construction. Ambitious targets
were set as early as in the planning phase.
On the basis of these targets, available
technologies were used to produce a building
that fulfills the highest efficiency standards.
CO2-neutral provision of heating, cooling,
and power
Only environmentally friendly, minimalemission, and recyclable building materials
were used for the construction. All working
areas, including the production area, have
natural light. The large glass surfaces offer
a high level of transparency. A photovoltaic
system provides 60 percent of the required
Five Viessmann air/water heat pumps are
used to heat and cool the building, and the
factory uses no fossil fuels – such as gas,
hard coal, or oil – at all. The walls and
windows are thermally insulated; cold
generated by the heat pumps reduces the
temperature within the whole building by
up to 10 degrees Celsius compared to the
outside temperature in summer.
With an investment volume of
several tens of millions, Viessmann
constructed a new plant in Manisa
for the production of wall-mounted
gas boilers.
The manufacturing process is designed according to the
most recent lean production standards and the Viessmann
VITOTOP production system principles.
VITOTOP: Continuous improvement process
in all areas
The VITOTOP concept is based on the principle of continuous improvement.
It increases productivity in the company from the supplier to the end consumer.
Initial stage of change management
VITOTOP forms the initial stage of change
management, which steers the optimization
processes of the entire group. Change
management is very important in Viessmann’s
environmentally oriented, sustainable
The aim of VITOTOP is to increase
productivity along the entire process chain.
By cutting out activities that do not add value,
efficiency is increased in production areas,
administrative departments, sales and all
the way through to the suppliers. Activities
that do not create value include unnecessary
transportation, production errors and the extra
work associated with them, overproduction or
excess stock.
Change management incorporates all tasks,
measures and activities intended to achieve
extensive change in the company. For
example, it includes the implementation of
new strategies, structures, systems,
processes and actions.
99.99 percent error-free
Quality is both method and target.
Continuous improvement is a permanent
element of Viessmann’s company culture and
is expressed in the motto: "Nothing is so good
that it cannot be improved." This sets high
standards – products and processes have to
be 99.99 percent error-free.
The objective of VITOTOP is to
concentrate on value creation in
every manufacturing process and to
eliminate wastefulness.

Sustainable purchasing ensures supplier quality
and reliability
Viessmann works together with suppliers who are committed to high standards of quality
and environmental and social responsibility.
Viessmann does not evaluate suppliers
according to quality and price alone. In
accordance with our company principles,
Viessmann has developed sustainable,
international purchasing processes and
methods for all its main suppliers that include
social, ecological and ethical standards.
Due to the high share of material costs, it is
essential to consistently work in close
cooperation with all key suppliers worldwide
to ensure product quality, competitiveness
and supply reliability. Quality, costs and
logistics are considerably optimized thanks to
this close interaction. The Viessmann Group's
principal supplier strategy is analyzed regularly
and standardized by the Procurement
Department together with all principal
suppliers in meetings and workshops. The
purpose of the meetings is also to identify
joint improvement potential, set targets and
define execution. The primary goals are:
Improving quality
Enhancing supply performance
Boosting efficiency in all key purchasing
Increasing flexibility
Raising reliability of supply
Integrated supplier development,
especially in terms of compliance with
environmental and ethical standards
To ensure efficient procurement processing
and guarantee that targets are consistently
met worldwide, it is necessary to
standardize and systematically apply the
processes, guidelines and content of the
commodity strategy with all suppliers. This
necessitates a close, ongoing, open
relationship of cooperation between the
supplier, the purchasing departments and
related business units.
Regular audits
Viessmann conducts supplier audits on a
regular basis to ensure that quality capacities
and awareness remain at a high level. In a
standardized procedure, all suppliers are
subject to the same criteria and can be
objectively compared with one another.
Precisely described processes are adhered to
for this supplier management system,

EMAS and ISO 14001 certificates
attest to the high standard of
environmental protection
maintained by Viessmann.
For decades now, Viessmann has
implemented a concept of integrated
environmental protection throughout its
manufacturing, logistics, administration,
research and development.
Viessmann Group environmental
management system
Viessmann has already been implementing an
environmental protection concept, which is
integrated into all of the relevant processes,
for decades. From product development
to purchasing, production, distribution, and
product use – the company’s guiding principle
of sustainability is applied to all processes. In
addition, Viessmann has set up a voluntary
return system for used equipment to close the
material cycles at the end of a product's life
and, in turn, boost resource efficiency within
the sustainable heat supply.
Processes impacting the environment are
subject to a uniform standard throughout the

Energy management according to
DIN ISO 50001
The aim of energy management is to
systematically record and analyze energy
consumption and derive suitable measures to
increase efficiency from the results. This
approach is used to define measures to
achieve the long-range goal of a sustainable,
CO2-neutral heat supply at the Allendorf
(Eder) site.
In March 2011, the energy management
system in Allendorf (Eder) was certified
according to DIN EN 16001. This European
standard, which was replaced by the
internationally valid DIN EN ISO 50001 in
December 2011, serves as a guideline for a
standardized system for continuously
improving energy performance. The
company's headquarters in Allendorf (Eder)
have been certified according to ISO 50001

Viessmann’s sustainability project for resource efficiency, climate protection, and job
As part of Viessmann's sustainability
strategy, the sustainability project for improved
efficiency is based on an integral concept for
resource efficiency, climate protection, and
job security. The project serves as an example
of best practice and is designed to motivate
other companies as well as political and
administrative decision-makers to advocate
or implement similar measures to improve
energy, work and material efficiency.
The main purpose of improving the
efficiency of work processes was to increase
the competitiveness of jobs and, in doing so,
to contribute to securing the Allendorf (Eder)
site. Manufacturing structures and processes
were redesigned according to efficiency
criteria when lean production was introduced,
resulting in a complete reorganization of
the production concept. As a result,
productivity was increased by up to
20 percent, while space efficiency was
improved by about 30 percent.
The other factor of material efficiency involves
the economic use of raw materials in the
production process. In concrete terms, steel
and water consumption has been reduced by
half and the recycling rate has now reached
99 percent.
Innovative energy concept
The energy concept for the Allendorf site
pursues a dual energy strategy that combines
improving efficiency and replacing fossil fuels
with renewable energies. This encompasses
the new construction of an energy center and
measures to decrease the energy used by the
manufacturing process. These include:
 New high-efficiency machines and systems
 Needs-oriented management of pumps,
engines, and lighting
 Improvement of system hydraulics
 Heat recovery center to exploit the waste
heat generated by the industrial processes
 Insulation of the building envelope
Viessmann grows
The energy center of the future
The energy center operates on both fossil
fuels and renewable energy, including oil, gas,
biomass, solar energy as well as ambient and
geothermal heat. Innovations such as
condensing technology and CHP solutions
ensure that the fuels are used efficiently.
When it comes to renewable energy,
Viessmann is committed in particular to
biomass obtained locally from the company’s
own short-rotation plantations. Over an area
of 170 hectares, poplars and willows have
been planted, which are harvested every
three years and used as an energy source in
the form of woodchips. A dry fermentation
biogas plant delivers an additional 2.7 MWh of
heat and power annually.
Accolades for strategic sustainability
Viessmann’s sustainability project was
recognized with the 2009 German
Sustainability Award in the category
"Germany’s most sustainable production",
the 2010 Energy Efficiency Award from the
German Energy Agency (dena), and the
internationally acclaimed ENERGY GLOBE
World Award. In 2011, the company also
received the German Sustainability Award in
the category "Germany’s Most Sustainable
Brand" and in 2013 in the category "Exemplary
Resource Efficiency".

5 Protection of the Environment & Resource Efficiency
Increased efficiency, greater share of biomass and
green electricity reduce CO2 emissions even further
In order to tap further potential for increasing efficiency and protecting the climate,
Viessmann‘s strategic sustainability project is being developed on an ongoing basis.
The retrofitting of the energy center
completed in 2012 has increased the share
of biomass in the heat supply from 50 to
80 percent. The long-term goal is to supply
all energy using this climate-friendly fuel
source. This is governed by the principle of
sustainability, in other words only using as
much biomass as can be regrown in the same
period of time.
Second biogas plant in operation
Moreover, a second biogas plant in Allendorf
(Eder) is in operation. It is a wet fermentation
plant from Viessmann's subsidiary Schmack
Biogas GmbH, which produces 1.6 million
cubic meters of biogas from 15,000 tonnes of
substrate annually. In concrete terms, using
this biogas can provide 1,650 households with
electricity and 370 households with heat.
Furthermore, in 2014, an ice storage system
was installed as energy source for a brine/
water heat pump with a heat output of
27 kW. The heat pump's output is 21 kW
when performing cooling operations. The
next step is to reduce energy consumption
even more. Additional efficiency measures
are planned for manufacturing, for example
optimizing the sheet metal powder coating
Using a technology developed by Viessmann
Group member Carbotech GmbH, the biogas
is upgraded to natural gas quality and fed into
the public gas network. This means the gas
can be used to produce electricity and heat
anywhere there is a gas connection,
regardless of where it was generated in the
first place. Furthermore, the gas network can
be used for storage purposes, making the
generation and use of gas independent of
one another over time. Like the first biogas
plant, the new system will be supplied with
substrate from local farmers and the
Maschinenring Waldeck-Frankenberg.
CO2 emissions reduced by 80 percent
In order to further reduce CO2 emissions,
exclusively environmentally friendly
hydroelectric power generated in Germany
has been used at the Allendorf (Eder) site
since January 1, 2012. CO2 emissions have
decreased by 80 percent compared to 2005
as a result.

Viessmann has developed an innovative
concept for an energy-saving, environmentally
friendly supply of heat and electricity at its
sales offices, as part of which sustainability
goals are defined early in the planning phase.
By implementing technology already available
on the market today, these cutting-edge
buildings have been constructed according to
the gold standard of the German
Sustainable Building Council (DGNB) and
meet the requirements of the Energy
Performance of Buildings Directive (EPBD) for
the year 2020.
Complete supply from renewable energy
This concept provides a complete supply with
electricity and heat from renewable energy
sources. High-efficiency heat pumps are used
for heating and cooling the rooms in the
summer months. Solar energy is also used;
vacuum tube collectors mounted on the
facade supply the buildings with domestic
hot water. Photovoltaic panels installed on the
roof generate electricity, which is fed into the
In addition to the modern industrial solutions,
the buildings are constructed with tripleglazed windows and an insulated building
envelope. In this way, the generated heat is
used as efficiently as possible. The energy
concept also incorporates environmentally
friendly electricity from renewable sources
such as biomass, water and wind power. This
means that the overall heat and power supply
of the buildings is CO2-neutral.

Challenges of demographic shift
Economic success at our company is linked to welfare of society as a whole and the
preservation of an intact environment for generations to come.
This attitude is reflected in the loyalty and
dedication of our employees who often stay
with the company for decades.
It is becoming increasingly difficult to find
well-qualified new employees in Germany.
According to a survey conducted by the
German Federal Statistics Office (Statis­
tisches Bundesamt), the number of people
in employment will drop by 11.6 percent by
2030. At the same time, the share of over50-year-olds in the workforce will increase to
33 percent.
Competition for talented workers is already
fierce today. More than 33,500 apprenticeship
positions could not be filled in 2013 alone.
One out of two companies perceive problems
in meeting its needs for qualified employees.
There will be a shortage of roughly 6.5 million
skilled workers in Germany by the year 2025.
Maintaining and improving business
Targeted measures are necessary to
counteract this development and to maintain
and improve the company’s competitiveness
regardless of these demographic shifts and
their consequences. These include:
 Flexible working time models and phased
 Continuous improvement of further
 Targeted personnel development and
The way to successfully achieve these
measures is to cultivate a culture of

More than 3,000 young people have started
their careers with an apprenticeship at
Viessmann in the past decades. Currently,
approximately 500 apprentices are being
trained in 16 different vocations, and another
90 bachelor students in eight combined
work-and-study courses are employed by the
company. Furthermore, the company provides
11 places every year for trainees in the EQ
scheme (entry qualification).
Viessmann offers the part-time bachelor
courses of study in cooperation with the
University of Applied Sciences of Central Hesse
and the Baden-Württemberg Cooperative State
University in the following fields:
 Accounting & controlling

Integrating theory and practice
Viessmann supports the part-time bachelor
program at the University of Applied
Sciences Central Hesse (THM) as a member
of the "Competence Center Duale Hochschulen e. V.", a combined work-and-study
program. The combination of a university
program with work placements in the
company guarantee close links between
theory and practice. And, as a result, the
program not only produces highly qualified,
practice-oriented technical and managerial
personnel, it also fosters a direct transfer of
knowledge between universities and
The "Apprenticeship Plus" project is another
initiative designed to combat the general
shortage of highly qualified technicians. This
innovative training concept is designed to
help school leavers with average attainment
to qualify for university study. In parallel to a
three-year apprenticeship, participants qualify
themselves to attend a university of applied
sciences. It is thus possible to complete not
only an apprenticeship within just six years of
leaving secondary school, it is also possible to
complete university studies.
Viessmann offers a broad range of
training and education courses for
all employees.

Human resources development and internal
training secure continuous improvement
Long-range competitiveness in international markets and job security necessitate the
systematic promotion and development of the workforce.
These overarching objectives can only be
reached when they are broken down into
smaller goals to be achieved by the individual
For this reason, participating in task-specific
training is compulsory for all Viessmann
employees. Depending on functions and
responsibilities in manufacturing or
administration, training may include:
Management qualifications
Method-related qualifications
Social qualifications
Specialist qualifications for sales
Other qualifications
HR development system and management
The system of human resources development
is based on the company’s brand values and
management principles and supports their
execution. It consists of the following
 Tools for goal orientation
 Feedback and evaluation systems
 Tools for personnel development
Supervisors and staff use the tools together.
Competition for talented workers
is already fierce today. Viessmann
counters this process with a
targeted human resources
development strategy.
Respectful interaction for mutual
Tools for goal orientation
The key component of goal orientation is
the Management by Objectives (MbO). At
the beginning of the year, each employee
agrees with his/her supervisor on specific
goals and objectives. In May and September,
they review together to what extent those
goals have been attained. In between status
reviews, employees can count on supervisors
for assistance and request a coaching
meeting at any time.
Feedback and evaluation systems
The feedback and evaluation systems consist
of regular performance assessments and
development meetings. To determine an
employee’s potential for development,
management compares the achievements of
the employee with clearly defined job
descriptions with the help of a qualification
matrix. This ensures a standardized
Safety and health – our most important assets
Sustainable business means accepting responsibility – for the environment, for all
stakeholders and therefore for all employees.
To permanently ensure employees‘ safety,
health and performance, extensive measures
for occupational safety have been integrated
into all essential company processes. They
range from preventive measures such as
assessing workplaces and training managers
and staff, to investigating accidents.
By obtaining certification in accordance with
OHSAS 18001 (Occupational Health And
Safety Assessment Series), Viessmann
reinforces its leading position in the industry.
The initial inspection in 2011 was followed by
the first recertification in September 2014.
Reportable accidents well below industry
The number of reportable accidents at work
per million working hours ("quota per million
working hours") at the Allendorf Werke has
remained below the average of the
employers’ liability insurance associations in
Germany for many years.
No apprentice in Allendorf (Eder) has had a
reportable accident for over five years – an
outstanding achievement considering that
young people between the ages of 18 and
25 are statistically at highest risk. As a result,
Viessmann trainers were honored by the
wood and metal employers’ liability insurance
association for operating 1,000 days without
an accident in 2012.
Viessmann regularly takes part in
preventive campaigns.
Avoiding accidents also a topic in ideas
Avoiding accidents also plays an important
role in Viessmann’s ideas management
system. Since 2012, safety-related
suggestions for improvement, for example
after "near accidents", can be submitted as
"quick ideas". Already in the first year, more
than 1,900 suggestions regarding
prevention were submitted and implemented
with this new system at the Allendorf (Eder)
plant alone. In 2014, more than 2,300 "quick
ideas" were submitted.
A health promotion day is held
annually at the Viessmann Werke
Whereas the average number of accidents
reported by the employers’ liability
insurance associations was approximately
14.91) per million hours in 2014, the same
figure at Viessmann Deutschland GmbH was
6.2 and at Viessmann Logistik GmbH 3.3. Six
member companies at the Allendorf site have
a quota per million hours of zero,
including the production companies
Viessmann Wärmepumpen GmbH and
Viessmann Elektronik GmbH. The accident
quota per million hours at the entire Allendorf
(Eder) site is 5.0.
Apprentices more than 1,800 days without
Viessmann has a number of preventive
measures in place to continuously reduce its
accident rates. This especially applies to the
area of technical apprenticeships.
Viessmann trainers were honored
by the Wood- and Metal-working
Professional Association for
operating 1,000 days without an
accident. In the meantime, the
Allendorf-based apprentices have
even worked for more than 1,800
days without a reportable accident.

Getting involved is worthwhile: Viessmann Award
open to all employees
At Viessmann, top performance and the continuous pursuit of improvement have always
been encouraged and rewarded.
More than 50 years ago, Viessmann
introduced a system for submitting
suggestions, which led the way to today’s
ideas management. The annual sales
competition held since 1980 provides strong
incentives for increasing sales and turnover.
In 2014, an innovation award was sponsored
for the fifth time to recognize projects with
strong innovative potential. This team
competition is designed to identify and
capture innovation potential within the
Viessmann Group and promote cooperation
between employees, departments and
member companies.
These three pillars – ideas management, the
sales competition and the innovation award –
make up the Viessmann Award.
It is not limited to specific business areas,
such as
manufacturing or sales, or to specific
locations or Group members; all employees
are entitled to take part, as their daily work is
essential to the company’s success.
Category "Continuous Improvement
Good ideas are an investment in the future.
They help refine products and services,
strengthen the company’s competitiveness
and secure jobs. Viessmann employees have
a wealth of experience and knowledge and
are a source of powerful ideas.
Independently of the bonuses or "idea points"
awarded by the ideas management system,
there are two ways of taking part in the
"Continuous Improvement Process"
category – either on the basis of the number
of improvement suggestions submitted or on
the basis of the total savings potential.

Sales competition
The aim of the sales competition is to
generate customer enthusiasm for
Viessmann, promote sales and increase
turnover. Points are awarded for every heat
source sold; sales revenues and reaching
targets are the criteria for winning the award.
The sales competition addresses the German
and international sales organizations as well
as the sales teams at Viessmann Kühlsysteme
Every employee can take part in this team
competition, with ideas that have been
successfully transformed into new products,
processes or services. The emphasis is not
only on technical projects, it also lies on
innovations in the areas of further education,
administration and environmental protection.
With 15 projects submitted from the areas
of manufacturing, sales and administration,
the Innovation Award met with tremendous
response in 2014. The suggestions ranged
from process optimizations in manufacturing
and logistics to new business models through
to product innovations.
Social commitment
Relationship of trust with politicians and
Viessmann works closely with policymakers and associations in a spirit of trust. This work
focuses on commitment to climate protection and the provision of a sustainable energy
supply in the future.
Viessmann is one of currently 29 members
of the German climate protection industry
group. The German Federal Environment
Ministry, the Federal Ministry of Economics
and the German Federation of Chambers of
Commerce (DIHK) launched the partnership
in 2009 together with Viessmann and three
other founding companies.
"Companies for Climate Protection" –
coalition with ambitious goals
Member companies must fulfill strict criteria.
For example, climate protection and energy
efficiency must be an explicit element of
company policy and activities in this area must
be regularly publicized. Furthermore,
consumption data and greenhouse gas
emissions must be systematically logged and
documented, and the issues of climate
protection and energy efficiency must be
anchored in the company‘s training and
professional development programs.
The purpose of the partnership for climate
protection, energy efficiency and innovation
is to develop the existing potential for climate
protection and energy efficiency in the
companies. Additional aims are to drive
forward the use of innovative technologies
to tap this potential in business practice and
to create a framework to achieve ambitious
climate-protection and energy-efficiency
goals in an affordable manner.
BDI initiative "Energy Efficiency in
The BDI Federation of German Industries
has started an interdisciplinary initiative for
energy efficient buildings. In addition to
Viessmann, 19 associations and companies
from the building sector belong to the group.
The joint goal is to capture the enormous,
largely untapped potential for energy
efficiency in buildings. Increasing efficiency
in buildings is critical to the current debate
on the future structure of the energy supply
system in Germany.
The aim of the initiative is to actively shape
the political framework for climate protection
and growth as well as to increase awareness
of the potential for improvement and its
economic repercussions. Innovative
technologies and system solutions are also
presented and the expertise of the German
industry at finding solutions is conveyed.

Sustainable energy era –
a mission for society as a whole
In Hesse, the goal by 2050 is to cover all electricity and heating needs with renewable
energy. The state administration aims to be CO2-neutral as early as in 2030.
Just a few days after the nuclear catastrophe
in Fukushima (Japan) on March 11, 2011,
Hessian Minister President Volker Bouffier
called for a Hessian Energy Summit to be
established. Four working groups met with
representatives of all organizations relevant
to energy issues – the parliamentary groups
in the state of Hesse, representatives from
municipalities, trade and environmental
associations, unions and industry – to discuss
several key topics:
The development of a viable energy mix of
renewable energy and fossil fuels
The identification of potential for energy
efficiency and savings
Requirements for a reliable energy
infrastructure and secure energy supply
Society's acceptance of changes to energy
Viessmann actively contributed its expertise
to the working groups on "Establishing a

Regardless whether condensing boiler, heat
pump, pellet boiler or micro combined heat
and power system – Viessmann‘s Energy
Savings Check calculates potential savings
for modernizing with these heat generators
by making only a few entries. It is therefore
the ideal tool for trade professionals to advise
their customers. The free-of-charge
consulting program has now been extended
to become the Building Energy Savings
Check. Thanks to the objective results it
delivers, it has been the only program of its
type to be certified by TÜV (German technical
supervisory association) Rheinland.

Awareness and orientation:
Viessmann forums
If the German federal government’s energy and climate policy targets are to be met, the
backlog of modernization in existing buildings urgently needs to be eliminated.
However, uncertainty continues to dominate
the market, on how to reach the German
government's energy and climate policy
targets can be reached. Information and
persuasive argumentation are more important
than ever in the dialog with investors and
system users.
Home and apartment owners are aware that
investing in the energy efficiency of their
buildings not only helps protect the climate
and promotes a sustainable energy supply
for the future, but it also helps in particular to
save heating costs and to increase the value of
their real estate. However, most of them have
decided to "wait and see," primarily due to the
unreliability of government subsidy programs
as well as incorrect and at times contradictory
information about the future viability of the
various energy sources.
Increasing awareness, giving orientation
Viessmann hopes to increase awareness and
provide its market partners with persuasive
arguments to give their customers orientation
and empower them to make the right
The Viessmann technical and energy forums
offer plenty of opportunity for discussion and
sharing experiences. Since their inception in
2008, roughly 3,200 market partners –
including heating contractors, designers,
architects, and engineers – have taken part in
the forum events held at the Viessmann
Academy. This shows that there is a great
need for factual information and clarification of
political and technological issues.
Renowned experts from research and
At these events, renowned experts from
politics, research and the heating
technology industry present their views,
elaborate on solution approaches and take part
in Q&A sessions. Regularly featured speakers

In the technical forums, the participants
discuss the current regulations and energy
