On June 1, an important strategic move in our management has

taken effect: After 37 years at the company, I have decided to hand over operations management, that means the position of the Chief Executive Officer (CEO), to Joachim Janssen. Mr. Janssen has been a member of Viessmann's Executive Board since

Changes in Viessmann management

Supervisory board reorganization

2007, and he has been Chief Digital Officer and my deputy since 2015. My son Maximilian is postponing his plans to prepare for his later responsibilities in the company to take over the CDO position from Mr. Janssen for a limited period of time. He has already been a member of the Digital Steering Com-mittee alongside Mr. Janssen and me,

and played a significant role in advanc-ing the digital transformation. As for myself, I will focus on my role as Presi-dent of the Executive Board, the hig-hest management body of our Group, and will devote myself more to stra-tegic responsibilities. In addition to me as President, the following delegates belong to the Executive Board:

Joachim Janssen (Group Chief Executive Officer)

Dr. Ulrich Hüllmann (Group Chief Financial Officer)

Klaus Gantner (Group Chief Administration Officer)

Maximilian Viessmann (Group Chief Digital Officer)

As part of the changes in the Executive Board, we will be strengthening the divisions further. The "Division CEOs" Dr. Klaus-Peter Kegel

(Division 1 – Heating Systems) Dr. Tino Weber

(Division 2 – Industrial Systems) Dr. Frank Schmidt

(Division 3 – Refrigeration Systems)

and the Executive Board together make up the Executive Council.

I am convinced that these changes are setting the right course for the future at just the right time, particularly in the context of the current challenges posed by the digital transformation.

The challenge of digitalization

Digitalization is an immense challenge that our industry has to face, but it also represents a great opportunity. To take advantage of it, we have begun the process of digitalizing the company on all levels. On the one hand, it applies to the organization, which we are bringing into line with digital transformation in

the sense of Industry 4.0. Furthermore, we are adding appropriate talent to this end. On the other hand, and as already announced at ISH 2015, connectivity will also be one of the core product characteristics in all Viessmann heat generators. We are also pushing digital-ization in marketing and sales, in order to use their potential in concert with our market partners: Viessmann repre-sents a well-known, domestically recognized German brand that has an extensive online reach, comprehensive online marketing expertise and the requisite IT resources. The market partners contribute a local presence on the ground, the required expert know -ledge and the necessary installation and service resources.

The challenge of the sustainable

energy era

The second major challenge is the ener-gy transition. It can only succeed if the backlog in the modernization of existing heating systems is eliminated, thus allowing an energy efficiency increase in the heating market and growth in the share of renewable energy. Viessmann not only provides the necessary tech-nology for it, but all associated services as well. In addition, we have found two cooperation partners in BMW and Audi, with whom we can access new ap-proaches in the area of energy efficien-cy, develop sector-linking opportunities for power, heat and mobility and unlock the potential there.

Exploiting opportunities jointly

We will not only help to shape the on-going changes in our industry, dear cus-tomers, we will also take full advantage of the opportunities that accompany them in partnership with you.

GUEST ARTICLE

46 German men and women biathletes have stood on the winners' podium at Olympic Games and world champion-ship contests over the past 25 years. Four women and two men were also able to celebrate World Cup overall victories.

"The current team will not be able to continue this tradition." This and similar

Support for emerging talents is worthwhile

In sports as well as in the company

by Sven Fischer

predictions were uttered by a number of experts three years ago when a ma-jority of the established athletes retired from active participation.

Apart from the fact that it makes little sense to compare current athletes based on the successes of the retiring ones and that it should always only be about the current competition, the fears proved to be wrong. Laura Dahlmeier, Franziska Preuß, Vanessa Hinz and Franziska Hildebrand unex-pectedly won the title at the world championships in Kontiolahti in 2015, and another athlete from the Viess-mann team, Maren Hammerschmidt, joined the ranks of world-class athletes.

Their success continued at the 2016 World Championships in Oslo: Laura Dahlmeier became the world champion in the pursuit discipline as well as win-ning silver in the mass start and bronze in both the sprint and individual com-petitions. She also secured the bronze in the relay race along with her Viessmann teammate Franziska Preuß, Franziska Hildebrand and Maren Hammerschmidt. The silver went to the German men's team with the Viessmann athletes Benedikt Doll and Arnd Peiffer.

This fortunate development, which gave lie to all doubters and naysayers, would not have been possible without the committed, specific support for youth in the German Ski Association (DSV). Viessmann already began sponsoring

the junior team during the 2007/2008 season and has ensured that all DSV C-squad athletes receive professional support ever since. The company's support guarantees that training camps are carried out, technical materials are on hand and top trainers are hired. And that pays off!

Fostering young people is not limited to sports at Viessmann. The apprentices and combined work-and-study program students benefit from hands-on voca-tional training that goes far beyond the defined curriculum requirements. Pupils are inspired to pursue pro -fessions related to engineering through programs offered by the Young Engin-eer Academy or the Young Technician Academy.

Viessmann's commitment to young people creates the environment for giving their best performance every day: at venues for sports competitions as well as inside their own company.

Personal detailsSven Fischer is one of the most successful biathletes of all time. The native of Germany has stood on the winners' podium more than 150 times – at world champion-ships, the Olympic Games as well as World Cup contests. He cap-tured four Olympic gold medals and was a world champion seven times. He ended his sports career in 2007 and became a Viessmann brand ambassador. He is a popular and informative expert for TV audiences during live coverage of biathlon events on ZDF.

NEWS

A new thin sheet production line has been put into operation in the pro -duction department of Viessmann Industriekessel Mittenwalde GmbH. This has greatly reduced the turna-round time of many components. The variety of different thermal insulations for Vitoplex, Vitocrossal and Vitorond boilers required a client-oriented reorganization of the production depart-ment. The thermal insulations are now manufactured as a set directly from the coil, and, if required, lot sizes of 1 are also possible. The goals of reducing set-up and turnaround times and imple-menting a production department with-out forklift trucks were also achieved. Altogether, the turnaround time in the fine sheet production department was shortened by more than 80 percent.

Viessmann Mittenwalde: New thin sheet production line

The Viessmann IT Service GmbH, in co-operation with the Norwegian team from the Norpe Group, developed a new e- commerce system. This enables clients in Norway to order ready-to-use refriger-ation cabinets and online services.

The system guarantees rapid ordering and intelligent logistics management. The new e-commerce system opens up a new business area and offers clients a complete all-round service.

Norpe: New e-commerce system

Stock-taking, maintenance and servic-ing as well as the transportation of re-frigeration and freezing cabinets are now all possible from a single source. The age, condition and location of the refrigeration and freezing cabinets are clearly presented, and the logistical processes are simply and efficiently organized. This gives the clients, too, constant access to all data. An exten-sion of the e-commerce system to other countries is planned.

The "Best apprentice idea in Germany 2016" comes from a Viessmann appren-tice. Christian März, who qualified as a product designer at the company's headquarters in Allendorf (Eder), won over the international jury at the annual conference of the German Institute for Ideas and Innovation Management in Berlin.

His award-winning suggestion was to re-construct the soldering units in the heat pump manufacturing department, so that wear and tear on them was greatly reduced. This reduced repair costs by almost 90 percent. In the last three years, Christian März has sub-mitted a total of almost 100 ideas.

Award for "Best ap-prentice idea"

Boilers older than 15 years will be marked with a new label from 2016 on-wards, giving information on their ener-gy efficiency. The first efficiency labels were given out by Uwe Beckmeyer, Parliamentary State Secretary at the German Federal Ministry for Economic Affairs and Energy, during a joint event with the Federation of German Heating Industry (BDH), the German Central Association of Plumbing, Heating, and Air Conditioning (ZVSHK) and the Fed-eral Association of Chimney Sweeps – Central Trades Association (ZIV).

The old-boiler label is a way of inform-ing consumers about the inefficiency of their old heat generator and about existing requirements and energy con-sultancy possibilities. This is meant to motivate people to conserve energy and replace their old heat generator. Ex-pert tradesmen, chimney sweeps and energy consultants are entitled to attach the labels. From 2017 onwards, local chimney sweeps will be obliged to attach them.

Launch of labels for old systems

Award ceremony: Business administration graduate Christiane Kersting (German Institute for Ideas and Innovation Management), Martin Hirsch (Trainer for the profession "Technical product designer"), Christian März (technical product designer) and Peter Becker (Head of Ideas Management).

Turnaround time is considerably reduced with the new thin sheet production line.

HEATING IN THE BUILDING SECTOR

The West European heating technology markets grew last year by 1.6 percent to 5.1 million heat generators. Market

development was much more difficult in some parts of Eastern Europe. The heating market declined sharply in Russia as well as the Ukraine. Development outside Europe was inconsistent: While the North American market was particularly stable, the momentum in China dropped off con-siderably.

Growth of four percent on German heating market

The heating market in Germany has increased by four percent, which is equivalent to a volume of 710,000 heat generators. According to information from the Federal Association of the German Heating Industry, this increase in turnover is due solely to increased demand for condensing technology, while systems using renewable energy once again had to suffer losses. Now that the market incentive program (MAP) has been augmented, the turnover situation for 2015 has improved slightly compared to the previous year, but the urgently needed turnaround is not in sight.

Modernization backlog remains

Although politicians have declared energy efficiency to be the second pillar of the energy transition and have better targeted the heating market with respect to its huge potential for effi-ciency, the long overdue elimination of the modernization backlog for existing heating systems has not really got going.

Climate conference offers new impetus

The Climate Conference in Paris has brought a new impetus for the further development of the political framework. Since then, there has been a lot of talk about "decarbonization" and "sector coupling", that is, the urgently needed linking up of heat, electricity and mobility.

Slight recovery in the heating market

Special effect due to the low price for heating oil

This single-family home on Lake Constance has an innovative system solution consisting of heat pump, photovoltaic system and electricity storage system as well as a charging station for electric vehicles, making it almost self-sufficient for energy.

It is clear that the necessary technol-ogies and concepts for achieving the political goals are definitely available, even for sector coupling and especially for the use of surplus wind and solar power.

Positive effects expected for 2016

There is still a huge modernization backlog: Three quarters of all houses were built before the first Heat Insu-lation Ordinance in 1977. Many build-ings are scarcely insulated, and the average age at which heating systems are replaced is 25 years.

The Federation of German Heating In-dustry is pleased that politicians no longer see the energy transition as simply a turnaround in electricity gener-ation. They have recognized the pivotal importance of the heating market for

their success. For example, the National Plan of Action for Energy Efficiency (NAPE) was initiated (see also a full article on the next page).

As a result of these measures, the sub-sidies for heating technology based on renewable energy have been increased in the course of the last year, for example, for heat pumps, biomass boilers and solar heating systems. For this reason, the association expects positive effects for this market seg-ment in 2016.

Slight increase thanks

to improved subsidies

Last year, improved subsidies led to a slight recovery for biomass boilers. The loss was still 30 percent in the first half of the year, but in the second half the situation eased noticeably so that alto-gether market losses of 18 percent were recorded.

Heat pumps, now common in new builds, were suffering from the high price of electricity. This technology kept more or less to the level of the previous

In this large residential building in Barsinghausen that was designed as a passive house, the photovoltaic system provides electricity for the home ventilation system with heat recovery.

The gas adsorption heating unit Vitosorp 200-F efficiently supplies enough power to a single-family home in Rosenthal/Hesse for heating the living space and for DHW generation.

Gas condensing technology and a solar thermal system for auxiliary heating and DHW generation supply the energy needs of a completely modernized residential home in Voerde/Niederrhein that is more than 150 years old.

This attractively integrated new build in the Frankfurt district of Sachsenhausen is supplied with electricity and heat from a micro CHP unit.

Currently planned legislation

The Federal Government has tar-geted the issue of increasing ener-

gy efficiency as a second pillar of the energy transition, against the back-ground of the National Plan of Action for Energy Efficiency (NAPE). Stock labeling, as described in the action plan, and the new energy efficiency incentive program of the German Fed-eral Ministry for Economic Affairs and Energy are providing a new impetus for eliminating the modernization backlog.

Stock labeling is aimed at increasing awareness among homeowners about the sizable efficiency potential of heat-ing modernization, that is to say, that they are wasting money with their out-dated systems.

The energy efficiency incentive pro-gram is funded with 165 million euros and is meant as a further motivation for the replacement of old boilers. It com-prises investment grants for fuel cell

heating systems, as well as special subsidies for combined measures when the heating system and heat dis-tribution system are modernized at the same time. In this way, the positive ef-fects negated by the failed tax depreci-ation allowance can be at least partially achieved.

year, with a market volume of 57,000 devices and a loss of two percent. Thanks to improved subsidies as part of the market incentive program (MAP), solar heating was able to re-cover in the last quarter of 2015. How-ever, it closed the year with a loss of ten percent, and a total of 100,500 systems were sold.

The Vitotwin 300-W takes up very little room because it is mounted on the wall.

Regulatory law not appropriate for

existing buildings

As a matter of principle, all energy policy measures should be planned so that the specifications are fuel-neutral and technology-neutral. Regulatory law, such as the obligation to use renewable fuel sources, is acceptable for new builds, but can be counter-productive in existing buildings. There is a good reason why the Federal Government's German Renewable Energies Heat Act (EEWärmeG) applies only to new builds. A clever, reliable subsidy policy with attractive incentives will be needed to eliminate the modernization backlog in existing buildings.

Anticipatory effects through

compulsory regulation

The example of Baden-Württemberg showed some years ago what can happen when regulatory law is used to intervene in existing buildings. The directive of the German federal state of Baden-Württemberg concerning re-newable heat with mandatory use in new and existing buildings has been in force since January 1, 2010. In 2009, this led to strong anticipatory effects and then to a wait and see attitude on the part of investors. Approximately 4,500 systems were modernized in advance so as to avoid mandatory use regulations. These systems are now inacessible to renewable energy for a further 20 years. Between 2010 and

2012, Baden-Württemberg had 20,000 fewer modernization projects com-pared to the development in the rest of the Federal Republic. The German Fed-eral Ministry for Economic Affairs and Energy aims to pass the amendment to the EnEG by the end of the year. The presentation of the draft to the Federal Cabinet is planned for this month.

Review of European regulations

As well as dealing with ErP labeling, the EnEG or the efficiency package, the legal system also has to deal with a whole series of further provisions that come from different sources. By January 2017, evaluations and reviews of existing EU-buildings guideline (Di-rective on the Energy Performance of Buildings, EPBD) and the Energy Efficiency Guideline (EED) will follow.

With the National Plan of Action for Energy Efficiency (NAPE), the Federal Government has set in motion a com-prehensive strategy for achieving this goal and increasing total energy efficiency. Moreover, the German Federal Ministry for Economic Affairs and Energy is already working on further proposals for more energy efficiency. The new proposals will be open for consultation by the publicin a "Green paper on energy efficiency". The green paper is also meant to serve as a discussion paper for the subsidy measures.

One of the most cost-effective measures for increasing energy efficiency in single- and two-family homes is to replace old boilers with modern heat generators. The picture shows the compact gas condensing boiler Vitodens 343-F.

Merger of German Energy Saving

Ordinance (EnEV) with German

Renewable Energies Heat Act

(EEWärmeG)

The political stakeholders consider the merger of the German Renewable Energies Heat Act (EEWärmeG) with the Energy Saving Ordinance (EnEV) in the Energy Saving Act (EnEG) to be a particularly important energy policy pro-ject for this year.

This merger is aimed at creating clear, uniform regulations for energy quality and the use of renewable energy in the construction industry. Up to now, crite-ria for the building envelope were de-fined by the EnEV and the integration of renewable energy into new buildings was regulated by the German Renew-able Energies Heat Act (EEWärmeG).

A heat pump driven by green electricity is a good solution for those who want to avoid fossil-based energy.

The ViCare app gives homeowners control over their heating system at all times and wherever they are.

Digitalization has changed our lives fundamentally, and digital

technology will continue to permeate our everyday professional and private lives. This is made possible by the widespread availability of rapid internet connections for both stationary and mobile applications, and the possibility this opens up for an exchange of in-formation at any time and from any place. Calling a taxi with an app on your smartphone or the electronic flight ticket that makes it unnecessary to stand in line at the check-in counter are just the beginning.

Countless opportunities thanks to

increased networking

More and more, things such as televi-sions or cars have also been connected to the Internet, not just computers and smartphones. That's why we talk about the Internet of Things. Forecasts as-

Digitalization changes a person's professional and personal life

A huge challenge, but with great opportunities

sume that by the year 2017 more than one trillion things, that is, more than 1,000 billion, will be connected to the Internet. When they are working in a network, there are many possible appli-cations. For instance, a car could in fu-ture reserve a table in a restaurant along the planned route or a parking place at the destination.

Completely new procedures in

industry and commerce

This trend is being accelerated by further technical developments: So-called cloud solutions (i.e. access to computer facilities and storage without a computer center of one's own) allow even small businesses or start-ups to develop their own applications and to offer them to a wide circle of recipi-ents. New sensors convey many kinds of information on the user's environ-ment and direct communication be-

tween machines is the basis of com-pletely new procedures in industry and commerce. Enormous amounts of data are generated in this way and 90 per-cent of all available data has been created in recent years. Evaluating this data can be the basis for new business models. Because, in addition to this, a sharp drop in costs has made it much easier to enter the market, businesses that penetrate existing areas of busi-ness or create completely new areas of business are popping up almost daily.

Opportunities of digitalization

Digitalization represents a huge chal-lenge for businesses, bringing with it opportunities as well as risks. That is why at Viessmann we are taking it very seriously. On the following pages, we will describe some examples of practical applications.

PRODUCTS

Heating systems will be Internet-capable in the future. Viessmann

now offers a solution allowing the com-pany's market partners to connect heat generators to the web via wi-fi using a simple plug-and-play installation.

Homeowners will be able to set tem-peratures or individual heating times very easily on a smartphone. Once cleared by the homeowner, trade pro-fessionals also have the option of viewing heating system operating parameters online to identify servicing needs and plan visits in good time.

Vitoconnect 100 – the Internet

interface

Vitoconnect 100 establishes a WLAN connection from the heating system to the homeowner's router. Available for both new appliances and for most existing systems, Vitoconnect 100 is connected to the control unit for gas or oil condensing boilers, heat pumps or biomass boilers and put into operation quite simply using the ViCare or Vitotrol Plus app.

ViCare – the new app for homeowners

This new app gives operators control over their heating system from any-where at any time using their smart-phone. The following functions are operated intuitively: Temperature settings Daily routines – including an

all-mounted and compact gas condensing boilers in the Vitodens

200 range up to 35 kilowatts (Vitodens 200-W, 222-W, 222-F and 242-F) are effi-cient heat generators for single- and two-family homes and apartments. Innovative technology now makes them even more convenient and more installation- and service-friendly than ever with all changes in the gas supply and air and exhaust gas conditions adjusted automatically.

Lambda Pro Control Plus

Lambda Pro Control Plus is the result of consistent further development of the time-tested Lambda Pro Control com-bustion control. No matter whether systems are switching between LL or natural gas or liquid gas, this new com-bustion control automatically adjusts the condensing boiler to the gas con-cerned without any manual help. The self-calibrating combustion control was already able to detect and compensate for fluctuations in gas composition be-fore now. Combustion remains perma-nently stable while maintaining the same, high degree of efficiency.

Vitodens 200 optimized

Wall-mounted and compact gas condensing boilers with new combustion control, automatic exhaust gas tract adaptation and innovative plug-in technology

Changeover to natural gas

Many parts of north-western Germany will be changing their gas supply from LL to natural gas over the next few years. Whether affected by the change or not, homeowners will be optimally equipped for the future with Lambda Pro Control Plus in Vitodens 200 range devices, so they should upgrade now. They then needn't worry about future changes to gas composition and will also benefit from an efficient heating system in their home.

Automatic exhaust gas tract

adaptation

Automatic exhaust gas tract adaptation auto-adjusts the burner fan to the resistance in the exhaust gas line concerned. To do so, it calculates the real combustion air volume and then modifies the burner fan speed to adjust the volume, ensuring optimum com-bustion conditions. This means that there is no need for manual adjustment on site by installing restrictors or setting the controller.

Space-saving, versatile and quickly installed, the new cascade system can operate up to six Vitodens 200-W wall-mounted gas condensing boilers (from 45 kW). Despite its capacity, it requires very little space. A triple cascade is now only 2.3 meters wide, and a ceiling height of 1.9 meters suffices – 40 centimeters less than usual cascades.

In the new dual pipe system, the feed and return lines run through a split collective pipe. This halves the number of seal points and thus also installation times.

VitochargeNew modular electricity storage system increases self-generated electricity usage and profitability of power generation

Increasing prices for mains electricity are making cheap electricity from an own CHP or photovoltaic system increasingly more attractive. The new Vitocharge electricity storage system is the ideal complement for own power generation. It stores self-generated electricity from CHP or photovoltaic systems not currently needed, ready for use at a later stage. This reduces de-pendence on public power supplies and increases the profitability and propor-tion of self-generated electricity used. Electrical appliances can also continue to run in the event of an outage in the power grid.

PRODUCTS

Viessmann and Schott are pres-enting a pioneering feature for

retailers: innovative smart access doors on new Leho refrigeration units. When a customer draws their hand near the door, the door quickly slides open silently with no need to touch the door. The system offers a variety of benefits for both market operators and customers.

Appealing staging of products

Rapidly advancing technological change, the increase in online sales channels and a growth in consumer experience and service orientation have made a great impact on consumer behavior, requiring great creativity and willingness to innovate from traditional store retailers. An attractive staging of products and integration of technology and design are becoming increasingly more important for in-store display.

Leho refrigeration units with smart access doors

Viessmann Kühlsysteme GmbH presents pioneering new feature for retailers

More convenient and hygienic

A joint project by Viessmann, Schott and other development partners for pilot client Rewe, the smart access doors are equipped with opening and safety sensors, which prevent the auto-matic opening and closing system triggering accidentally. Automatic open-ing is also more hygienic and more comfortable – the customer always has both hands free to take out products. The glass doors slide to one side in a pivot-swivel motion and do not project into the aisle, preventing open doors blocking the way for shopping trolleys, pushchairs or Zimmer Frames. The design brings another advantage with frameless product presentation behind barely noticeable, anti-reflective glass.

Up to 60 percent energy savings

Food retailer members of staff also benefit: a special operating mode holds

doors open, making it easier to fill or clean the shelves. Most importantly, these smart access doors contribute to climate protection since they make energy savings of up to 60 percent compared to open refrigeration units.

Reference project in Berlin

The many advantages of Viessmann Leho refrigeration units with smart access doors have also impressed man-agers at H.R. Ullrich Handels GmbH in Berlin. 21 Leho refrigeration units were installed over 55 square meters at the new Hit Ullrich Market in the district of Charlottenburg. After positive experi-ence from both the supermarket's members of staff and customers, the innovative doors will now also be used in the two other Hit Ullrich supermar-kets at the city's famed Zoo station and in Berlin Mitte, both scheduled for re-modeling over the next few months.

The moment a customer places their hand near the door, it quickly slides open silently with no need to touch the door.

"Digital Energy Solutions": tailor-made solutions for energy management

A Viessmann and BMW joint venture supports industrial companies in the identification, creation and marketing of energy efficiency and flexibility

Efficiency and sustainability are two of eight Viessmann brand

values, and an environmental protec-tion concept that is integrated in all relevant processes has been reality for decades. The sustainability project for improved efficiency, which is based on an integrated concept for resource efficiency, climate protection and job security, has resulted in a flagship pro-ject at the company headquarters in Allendorf (Eder), which is intended to

motivate other companies to take steps or push advancement in in -creasing energy, work and material efficiency.

Integrated energy concepts

Etanomics Service GmbH was founded to make the expertise acquired in re-gard to energy efficiency and energy management accessible to industrial and medium-sized businesses. Etanomics develops and implements

integrated energy concepts for the industry and the manufacturing sector as well as for services such as the restaurant sector. The aim of the con-sulting services on energy efficiency and energy management is to raise the efficiency potential in companies.

based system that supports SMUs in identifying, creating and marketing energy efficiency and flexibility. "Digital Energy Solutions" bundles the expert-ise and technologies of the two Groups, while drawing on the know -ledge of the Etanomics Service GmbH in the process, which acts as a service provider. "Digital Energy Solutions" follows an overarching approach that encompasses heat, cooling, power and electrical mobility.

Offers to companies from industry

and business

Both companies have a 50 percent stake in the joint venture based in Munich, and each provides a managing director. At first, the Digital Energy Solutions products will be geared towards customers in Germany and Austria.

Sustainability as a core

company value

The Viessmann Group already defined sustainability as one of their core company values decades ago. CO2 emissions were reduced by 80 percent, the consumption of fossil fuels reduced by 70 percent and percentage of re-newable energy utilized was increased to more than 60 percent within the scope of a flagship project at the company's headquarters in Allendorf (Eder).

Creation of an integrated,

measurable energy concept

In Viessmann's opinion, consulting, planning and implementation belong together when developing similar forward-looking energy concepts for other companies. In practice this essentially means that complete

solutions from a single source are always offered. Viessmann considers the entire company with all of its ener-gy consumption – from individual manufacturing processes to the entire location. That is how an integrated, measurable energy concept is created.

Comprehensive expertise of both

Groups

The BMW Group has been a pioneer in electric mobility with its BMW i con-cept and represents the world's largest service in access and utilization of public charging infrastructure. Further -more, the company plans to develop the integration of new and used high-voltage batteries into intelligent, stationary electricity storage systems as an independent business field. It is inevitable that the need for intermedi-ate power storage will increase dramatically due to the global trend towards renewable energy. Electric mobility will play an increasingly signifi-cant role in the process.

Energy systems management

The joint venture will use an IT system for intelligent management of energy systems (Smart Energy Backbone) that was newly developed by the BMW Group as a key building block. The BMW Groups has already been successfully relying on its proprietary energy data management in its global production network, leading to less power consumption, more production security and higher product quality.

Considerable potential for conserving energy in production was identified following a detailed load curve analysis.

Reference project Otto Spanner GmbH

Otto Spanner GmbH in Bayerbach, Lower Bavaria, serves as an out-standing reference for successful work completed by Digital Energy Solutions. Energy efficiency plays an important role as a possibility to re-duce the medium-sized, metal-work-ing company's business costs in a difficult competitive environment. After detailed load curve analyses were conducted by Etanomics Service GmbH, considerable energy

savings potential was identified. Fur-thermore, a transparency tool was developed that enabled centralized live capture and live visualization of the energy data at all company sites, thereby facilitating uninterrupted ener-gy controlling. That way all energy effi-ciency measures and the resulting cost savings can be monitored at a central location. That is also how cer-tification of ISO 50001 energy man-agement systems can be supported.

The power-to-gas facility at Viessmann headquarters in Allen-

dorf (Eder) was inaugurated jointly with the Prime Minister of Hesse and numerous guests from politics and industry in attendance. It is the world's first facility to utilize a biological pro-cess for methanation on an industrial scale.

"A strong part of Hesse"

"The Viessmann company is one of our internationally visible poster children. It stands for the impressive success story of a family business that com-bines tradition and innovation, thus shaping the future. Viessmann is a strong part of Hesse", said Prime Min-ister Volker Bouffier. In addition to the new power-to-gas facility, a planned re-search and development center, which the company is investing 50 million euros in, shows their commitment to their location in our state, according to the head of Hesse's government. "With that Viessmann is taking on social and

entrepreneurial responsibility and so is making an important contribution to the energy supply of the future, which is safe, environmentally friendly in addition to being affordable and socially accepted."

A new microbiological process

While methanation in other power- to-gas designs takes place on a chemical-catalytic basis, the Viessmann Group company, MicrobEnergy, de -veloped a biological process that has

been applied in Allendorf for the last year.

The first step involves using excess wind and solar power to make hy-drogen from water with the aid of an electrolyzer. In the second step, carbon dioxide from the neighboring biogas plant and the hydrogen are then con-verted to methane by a microbiological process.

Biological methanation impresses due to its optimum flexibility, making it emi-nently suitable to absorb fluctuating quantities of energy. Thanks to the use of existing biogas and waste water gas plants, the financial investment in power-to-gas plants can be reduced sig-nificantly since transformers, electricity mains connections, and gas network connections are often already installed.

Green gas for g-tron fleet

Methane can be stored in the gas grid for long periods of time because the as-sociated pipeworks and caverns have a storage capacity of several months. This serves the politically desirable linking of the power, heat and mobility sectors. The gas can be used for supplying heat, producing power or as a climate-friendly fuel for cars running on natural gas inde-pendently of where it is generated. That

is the reason Viessmann entered into cooperation with Audi and sells the bio-fuel to the car manufacturer.

Prize-winning project

The Allendorf power-to-gas facility was set up within the scope of the research project "BioPower2Gas", sponsored by the BMWi (German Federal Ministry for Economic Affairs and Energy) and was launched successfully: Performance tests showed that the gas quality goals were exceeded by 20 percent, and the TÜV-Süd (German technical supervis-ory association) verified that the quality criteria required by the "Bilanzierung Er-neuerbare Energien" standard for the sale of the gas had been met.

The facility also received certification according to REDcert-EU require-ments. With that, the requirements for sustainability and greenhouse gas re-duction as well as the traceability across the entire production and supply chain were fulfilled. The renewable natural gas is thus compliant with the basic requirements of the EU Directive 2009/28/EG.

The German Energy Agency (dena) has honored the project with the designation "Biogas Partnership of the Year 2015", thus highlighting the high efficiency and important con -tribution on the road to CO2-neutral mobility.

"A strong part of Hesse!" Volker Bouffier, Prime Minister of Hesse, on the Viessmann company.

Reiner Mangold from cooperation partner Audi AG: "Fill up gas-driven vehicles with excess wind and solar energy."

"Power-to-gas is an important pillar of the energy transition." Andreas Kuhlmann, Managing Director of the German Energy Agency (dena).

Viessmann and the Zurich-based Swiss -power AG are collaborating on the con-struction of biological power-to-gas fa-cilities in Switzerland. The objective of the collaboration is to realize the con-struction of such facilities on an indus-trial scale. Specifically, the sewage gas

generated by waste water treatment plants in Switzerland is to be converted directly into methane by means of a biological process and fed into the natural gas grid. That results in a renew-able energy plus and an increase in energy efficiency.

Successful completion of the ISO 50001 certification process

All European Viessmann locations have exceeded the requirements of the "Energy Efficiency Directive"

Germany and the EU have set ambitious climate protection

goals. An important step in achieving these is the implementation of the "Energy Efficiency Directive" (EED) into national law. Among other things, the provisions stipulate that large com-panies must carry out an energy audit every four years. An energy manage-ment system certified according to ISO 50001 releases it from this obli-gation, because the requirements profile of the system far exceed those of an energy audit.

The Viessmann company group has already fulfilled the EED requirements at all of their European locations since last year by introducing a management system compliant with ISO 50001.

Member of staff inclusion

The energy management appointees at the company's sites in Europe

implemented the project. Internal audits collected information on all energy consumers and energy gener-ators, derived savings potential from it and drew up a plan for implementing appropriate steps. Finally, executive managements were informed in management reviews and further goals jointly defined with the members of staff.

Support from Etanomics

Service GmbH

The energy management section took over the coordination of all the measures at the Viessmann head-quarters in Allendorf, with the support of Etanomics Service GmbH. A com-pany in the Viessmann Group, Et-anomics develops tailor-made solutions for energy and resource efficiency in the industry. Energy consumption is analyzed and savings potential is made transparent across the entire value-added chain.

Environmental pioneer Viessmann

As an environmental pioneer that had already anchored sustainability firmly in the company principles, Viessmann has been implementing an environmental protection concept that is integrated with all relevant processes for decades. From product development to procure-ment, production and sales to product use, all processes are geared to the company principle of "Sustainability". In addition to the certifications according to the internationally valid environ -mental management standard ISO 14001 and the DIN EN ISO 50001, Viessmann has the oldest EMAS entry in the European location registry. EMAS (Eco Management and Audit Scheme) is the most ambitious system in the world for sustainable environ-mental management.

The Polish city Wroclaw was be-stowed the title of European Capi-

tal of Culture in 2016. This city of more than 630,000 inhabitants is home to Viessmann's Polish sales company headquarters, and an in-house app development department (see also the article on the next page) was also established there in 2013. That was reason enough for "aktuell" to take a closer look at Wroclaw.

Capital city of Lower Silesian

Voivodeship (Poland)

Wroclaw lies in southwestern Poland and is the capital of the province of Lower Silesian Voivodeship. In the course of its eventful 1000-year history, it has belonged to Poland, the Czech Republic, the Habsburg Monarchy, Germany and Poland again since 1945.

80 percent of the building fabric was

destroyed

Up until shortly before the end of the war, Wroclaw sustained only minor damage, but then it was expanded to become "Fortress Wroclaw". Entire rows of stately houses were torn down at the command of the German Wehrmacht to make room for the construction of an airstrip. The relatively

short battle for the city just before the war ended ultimately destroyed up to 80 percent of the building fabric.

New construction according to his-

toric models

At the war's end, the Germans who had not yet fled Wroclaw were forcibly expelled, the city fell to Poland and was renamed Wroclaw (from Breslau). There were many professionals with aca-demic degrees, musicians, artists and architects among the new settlers, who proceeded to restore the city's Gothic and Renaissance features that had once given it the name "Venice of the East". Today most of the formerly vacant, derelict land has long since been rebuilt and remodeled according to the historic originals.

The city on twelve islands

Bridges play an important role in Wroclaw's setting – the city is located between a multitude of canals on twelve islands. Small water taxis shuttle passengers between the Oder islands and the city center.

The city is filled with life. In addition to the impressive architecture, literature, music, opera and theater enjoy a promi-nent status in Wroclaw.

Industrial center with a focus on IT

Wroclaw is Poland's second most im-portant financial center after Warsaw and has evolved into an industrial center with an emphasis on IT, KPO/BPO (Knowledge Process Outsourcing/Business Process Outsourcing), the automobile industry, electronics, household appliances and the life sciences. Just like everywhere else in the country, special economic zones and technology parks were built here, where companies benefit from favorable conditions, such as the Bukowice Industrial Park northwest of Wroclaw, the Wroclaw Industrial Park and in the Wałbrzych Special Economic Zone.

University of Science and

Technology

Toyota, Volvo and VW all have produc-tion sites in the region. Companies like LG, Philips, Toshiba and JVC have also contributed to the economic growth by investing here, as have international pharmaceutical and mechanical engin-eering companies. The Faculty of Mechanical Engineering at the Wroclaw University of Science and Technology, one of eleven academic institutions in the city, plays an important role in training qualified professionals.

PORTRAIT / DIGITALIZATION

The Viessmann F&E Center Wroclaw (Poland) was established in 2013.

A total of 60 members of staff headed by Tomasz Wroński work at the F&E Center. In addition to developing apps, the Viessmann Cloud System Estrella was also launched here. Furthermore, there is a team involved with creating a new field data management system, which is intended to help capture and evaluate the voluminous amounts of data from a wide variety of field tests conducted within the Group. This issue of "aktuell" will first introduce the app development.

Apps with big benefits

Nearly 50 million people in Germany own a smartphone with which they can access the Internet from (almost) any place. In addition, 40 percent of the population also owns tablet PCs. Since the sheer number of applications is so large, but the user's time is limited, it is important to develop apps that offer alot of usefulness and facilitate a lasting interaction with the user. A team of 20 is taking on this task at the F&E Center Wroclaw.

Vitotrol Plus and ViCare app

In addition to others, the Vitotrol Plus app was developed in Wroclaw. Moreover, the team assisted the IT department in Allendorf as well as the DBU (Digital Business Unit) during the development of the ViCare app. Vitrotrol enables con-venient remote control of the heating system via a mobile internet connection. The latest version of Vitotrol Plus as an app and energy cockpit furnishes comprehensive information on energy consumption in connection with the gas condensing boilers in the Vitodens 300

Growing importance

Against the backdrop of the quickly ad-vancing digitalization of the industry, applications for mobile terminal devices will continue to gain in significance. The next apps are therefore already in the process of being developed by the ex-perts in Wroclaw.

The committed young team in Wroclaw develops apps that help Viessmann engage in continuous interactions with the user.

High density of academic

institutions in Wroclaw

The reason that it's easier to recruit qualified members of staff in Wroclaw than anywhere else is because of the high density of academic institu-tions in the city – a majority of the eleven universities and academies offer courses of study in the IT field. The result is a continuing supply of new specialists in the labor market.

Award of the European Prize for Architecture in Berlin

Prize for Architecture "Energy + Architecture" to the winners in Berlin. Viessmann also supplied the compo-nents for the heat supply in the winning building.

"Exemplary energy upgrade"

The prize was awarded in its fourth year to the architect's firm of Freivogel Mayer Architekten GmbH from Ludwigsburg. The team won over the jury with their addition of another story to a high rise building in Pforzheim. "The project shows in an impressive manner how the transformation of existing residential buildings leads to improved living quality, especially if an exemplary energy upgrade has also been achieved", was the summing-up given by the jury.

Ice storage system and heat pumps

At the core of the energy concept is a Viessmann ice storage system with two Vitocal 300 G brine/water heat pumps. In the closed part of the south-facing wall, heat absorbers are integrated into the pre-fabricated elements over a surface of 92 square meters. They transmit their energy, ac-cording to current demand, either directly to the heat pumps or to the ice storage system situated under-neath the car park. Heating energy is stored there and is used as needed by the two heat pumps to heat the building. The high-quality thermody-namic building envelope also creates an aesthetically pleasing look for the building.

Sponsored by the BMUB

Architects from Germany, Austria and Luxembourg competed for the European Prize for Architecture, with a total of 50 buildings from six European countries. The award was sponsored by the Federal Ministry for the Environ-ment, Nature Conservation, Building and Nuclear Safety.

On the former training ground of the traditional football club

Rot-Weiß Oberhausen, a residential area of single-family homes is being created for which the city has a heat supply concept that is unusual in new build areas. On 10,000 square meters in the district "Am Rechenacker", 82 detached and semi-detached houses have been built which are supplied by the Energieversorgung Oberhausen AG (evo) with heat from wood pellet combustion via a local heating network. A Viessmann Vitoflex 300 UF boiler and four buffer cylinders are in operation.

Search for alternative heating

concept

The city authority, as owner of the land, commissioned evo to look for an alter-native heating concept. Local heating supply system, fueled by pellets, was chosen. The wood pellet concept was chosen to comply with the require-ments profile of the German Energy Saving Ordinance and the German Renewable Energies Heat Act, and also with regard to the total cost com-parison with other forms of heating.

A one-kilometer local heating

network

A pellet boiler with a heat output of 720 kW was installed in the heating center so that all the houses in the new build

area could be reliably supplied with heat. Four buffer cylinders with a total volume of 20,000 liters provide the necessary security, for example, if the boiler has to be switched off for main-tenance work. The water heated by the pellet boiler is transported to transfer stations in the houses, each with an output of 15 kW, via a local heating network with a total length of approxi-mately one kilometer.

Wood pellets have good

environmental footprint

The most important reason for the decision to use wood pellets as fuel is linked to the good environmental footprint of this fuel source – the com-bustion of wood pellets is CO2-neutral. In addition, wood pellets are easy to

use. The evo organization expects an annual efficiency rate of at least 90 per-cent for the large-scale wood pellet plant in Oberhausen. The calculated demand for wood pellets is 180 tons per year. The heating center and fuel storage are situated outside the resi-dential area in a specially constructed building.

Important contribution to climate

protection

In the new build area "Am Rechen-acker", the rejection of fossil fuels means a reduction of around 140 tons in CO2 emissions every year. With its local heating network, the evo or-ganization has created an exemplary project that makes an important con-tribution to climate protection.

PRACTICE

The city of Oberhausen has chosen an un -usual method of supplying heat to the new-build area "Am Rechenacker".

down

According to the schedule, upgrading should have taken place in the summer of 2015, but it had to be delayed out of consideration for the pregnant Siberian tiger Katinka and her young. Now the two little tigers that Katinka gave birth

to are themselves almost adult, so the boiler could be replaced without any problem.

euros were set aside for the fuel cell and its installation in the zoo.

High level of electrical efficiency

With Vitovalor 300-P, Viessmann is the first heating manufacturer to bring a mass-produced fuel cell unit onto the European market. Its high level of elec-trical efficiency, 37 percent, makes it particularly suitable for use in single- and two-family new build homes and in modernized existing buildings with a modest heat demand, and not just in big cats' enclosures.

German-Japanese joint

development

Vitovalor 300-P is a joint development with Panasonic. The fuel cell module is powered by natural gas and has an electrical output of up to 750 watts. It has already been installed over 50,000 times in Japan and has proved its worth there. In the course of one day, the Vitovalor 300-P system produces so much electricity that it covers most of the demand in an average household.

The athletes from the Viessmann Team brought home a total of 15

medals from the biathlon world cham-pionships held in Oslo this year. The most successful of them and one of the brightest stars at the Holmenkollen was Laura Dahlmeier.

Laura Dahlmeier shows

impressive results

The customs agent, who is just 22 years old, secured a formidable five medals, including the world champion-ship title in the pursuit discipline. Her personal results at the world champion-ships are impressive: gold, silver and three bronze medals.

A "complete" athlete

"Laura is so complete as an athlete that she has the stuff to dominate in women's biathlon sports for the next several years", is how Gerald Honig, national biathlon coach, assesses her and gives his reasons: "She is one of the strongest skiers, even though her performance is still a bit uneven due to her young age. In regard to shooting ca-pability – there are few that are as con-sistent as she is."

Mental toughness as a success factor

The most important factor of her suc-cess appears to be her mental tough-ness. She says that even in front of 20,000 people, as was the case in Oslo, she is able to focus her thoughts on summer training at her usual facility at home. Furthermore, she gives her all on the cross-country ski trail, which she proved by winning the silver medal for the mass start event.

The name of the athlete dominating everything in the Nordic combined events is Eric Frenzel. The 27-year-old prevailed to win the overall World Cup

victory for the fourth straight time. He also won the Nordic Combined Triple for the third time in a row in three com-petitions on three successive days in Seefeld. Team mate Fabian Rießle calls him the "best Nordic combined athlete of all time". Even national trainer Her-mann Weinbuch is consistently sur-prised by Frenzel, who only weighs 57 kilograms (125 lbs): "After his Olympic win in 2014 I already thought that he couldn't get any better." Yet according to Weinbuch, Frenzel's performance is in fact improving continuously and be-coming even more consistent.

The German Nordic combined athletes can also look back on an impressive season. Here the team around star athlete Eric Frenzel (front row, 3rd from the right) is enjoying their victory in the World Cup team competition.
