Foreword

Issue 4 12 Issue 4 13

I would like to welcome everyone to the fourth issue of the EcoCommercial Building Network’s Global EcoConstruc-tion Newsletter. Through these articles, we aim to highlight opportunities and developments in sustainable building that are occurring worldwide. As the ECB program continues to develop, more experts and partners worldwide are coming together to combine their resources and knowledge in order to meet the challenges of developing sustainable technologies and innovative designs to achieve high performance and efficiency.

With 65 uniquely positioned members worldwide, ECB program strives to ensure that energy-efficient and sustainable buildings are globally viable and cost-efficient. Our regional net-works are tapped into local building trends, allowing each one to leverage experience and innovative technology to suit various local conditions and business needs.

The ECB Network continues to build upon success through mutual collabora-tion and cooperation with the construc-tion industry and high-level business leaders. In its home nation of Germany, the ECB program has been deeply involvedrecently conducted a study of a sustainable supermarket that has projected its performance.Combining cutting edge designs and technologies, the supermarket has recorded an astonishing 75 percent reduction in energy consumption and 50 to 75 percent reduction in hazardous gas emissions.

The ECB Network also continues to expand worldwide. In June, the ECB Program officially launched in Brazil,

which expects rapid growth of sustain-able buildings in anticipation of the 2014 FIFA World Cup and 2016 Olympic Games. This marks a momentous occasion for the ECB program, as the Brazil program is the first in Latin America and certainly not the last.

Japanese building designers are faced with many constraints, due in part to the island nation’s unique topography. Nevertheless, the ECB program and Tokyo University have partnered togeth-er to develop a building prototype that achieves an 80% reduction in energy use compared to that of the common building. This is a very encouraging development, as it signifies not only that the ECB concept is applicable in Japan, but also that there are experts eager to work together with the ECB Network.

These are indeed exciting times, as ECB program continues to expand throughout the globe and partner with experts in environment-friendly sustainable construction. We look forward to a constructive dialogue and invite you to talk to us about our network, these articles, our technology and, above all, your needs.

Sincerely yours,

The prestigious award for "Best Practice of Global Green Building" highlights the ECB program’s global commitment to sustainable development in the building construction sector.

Bayer Initiative for Sustainable Building Honored at Rio Summit.

Rio de Janeiro, June 18, 2012 - A network of experts managed by Bayer Material-Science has been honored at the Earth Summit in Rio de Janeiro as a worldwide model for sustainable building. The award was presented to the EcoCommer-cial Building (ECB) program by the Global Forum on Human Settlements at a conference it is co-hosting with the United Nations. The award for "Best Practice of Global Green Building" was presented in recognition of numerous

Bayer-owned buildings built according to the ECB concept.

A climate-neutral administrative building opened near New Delhi in 2010 achieved a positive energy balance in just its first year of operation.

The global program established by Bayer MaterialScience in 2009 bundles the expertise of experts in various disciplines revolving around sustainable building. It counts over 65 partners, including compa-nies such as ThyssenKrupp, Stiebel Eltron and Philips. The objective is the planning and erection of tailored, energy-optimized buildings according to a holistic concept.

"The award demonstrates that the ECB initiative is the right tool for the global task of enabling sustainable living and building," said Dr. Thomas Römer, Head of Industry Platform Building & Construction, Industrial Marketing, Bayer Material-Science AG."Existing standards for climate protection, energy consumption, comfort and cost-effectiveness can be far exceeded

simply through the intelligent combination of existing technologies and solutions."

The Bayer buildings in the United States, Germany, Belgium and India are exemplary in this regard. For example, a climate-neu-tral administrative building opened near New Delhi in 2010 achieved a positive energy balance in just its first year of operation. Another CO2-neutral construc-tion project in the Brazilian metropolis of Sao Paulo is also following the ECB con-cept.

The most recent Lighthouse project in Qingdao involves the construction of a new office building which, when complete, will be Bayer’s first zero-emission building in China, and will be 100% carbon neutral. The project was developed under Bayer’s ECB program and takes full advantage of the program’s ability to deploy a wide range of innovative technologies in the area of sustainable building construction thanks to its local network of expert partners.

Bayer’s EcoCommer-cial Building Program (ECB) Wins “Best Practice of Global Green Building”Award

Cover picture description:

The Bayer MaterialScience EcoCommer-cial Building Conference Center is the first showcase in North America for the EcoCommercial Building Program. Located on the U.S. headquarters campus, this 800-ft2, solar-powered prototype incorporates a profusion of energy-con-serving and environmentally friendly technologies based on Bayer Material-Science innovations.

This past June, Bayer MaterialScience announced the launch of the EcoCom-mercial Building program in Brazil. The initiative, led by the German multina-tional corporation, expands the ECB program's integrated network of partners into South America for the first time with the goal of developing innovative solutions together with Brazilian experts and providing efficient solutions in the construction of sustain-able buildings. Already, the ECB program has connected with nine new local partners, which is a very promising start and bodes well for the future of “green development” in South America. A number of projects are also on the horizon, including a new ECB Light-house, which is to be the operation’s headquarters and will be located in São Paulo.

As one of the world’s major producers of greenhouse gases, Brazil presents a unique and interesting challenge for the ECB program and its partners. “The search for sustainable practices is a reality in the global construction market today and we are conscious of the role we have for the development of the best solutions”, said Thomas Roemer, Head of Industry Platform Building & Construction, Industrial Marketing, Bayer MaterialScience AG. According to Mr. Roemer, “This [Brazil] is a market of US$ 80 billion with a huge potential for growth. In the last 5 years, there was an increase of 300% in projects like that”. Bayer, with the EcoCommercial Building program, is a member of the Sustainable Buildings & Climate Initiative (SBCI), led by the United Nations Environment Programme (UNEP).

This subject is also under discussion in Brazil. "Currently, only about 1% of the Brazilian buildings are built according to

sustainable concepts. With the coming FIFA World Cup and Olympic Games and with the increased investment in the domestic market, this number will surely receive a great boost in Brazil and will approach the levels of more engaged countries, increasing to about 5%", says the head of Bayer MaterialScience for the Latin America region, Ulrich Ostertag.

The first ECB program in América Latina

In Brazil, Bayer MaterialScience set up an exclusive new business platform for identifying potential partners in the local market who are capable of developing sustainable projects. “ECB program will be the leader of a ‘green chain’ of representa-tives of all construction phases - from architectural design and construction to the reuse and disposal of materials and resources”, said Fernando Resende, the local executive responsible for the Eco-Commercial Building program in Brazil.

The program launches with nine partners: AcquaBrasilis, which specialises in waste-

water management and water treatment and rainwater harvesting; Andaluz Acessibilidade, a manufacturer of accessibility products for the visually impaired; Artecola, a manufacturer of adhesives, special laminates and engi-neering plastics; Command Commission-ing, a mechanical, electrical, plumbing and special systems commissioning company; Cushman & Wakefield, which specialises in infrastructure management and the LEED certification of enterprises; Grupo FCC, a manufacturer of thermo-plastic adhesives, sealants and polymer mortars; NS Brazil, which specialises in technical resin flooring and coating, anticorrosive products, and functional and decorative products for the industri-al, commercial and architectural sectors; Thermopol, a reference in roofing insulation; and Schneider Electric, a global specialist in energy management. In addition to promoting the program globally, Bayer MaterialScience also supplies raw materials to a number of sustainable building segments, and participates directly with an end product,

the Makrolon® high performance polycarbonate sheets. This sustainable building group is constantly expanding, accumulating new specialties and gearing up for large-scale construction of commercial projects such as supermar-kets, shopping malls and office buildings.

A new ECB Lighthouse

Bayer will also break ground later this year on a new company headquarters in São Paulo, in the city’s South side Socorro. The building will be the sixth ECB lighthouse in the world and the first one in Latin America—the others are in Germany, Belgium, United States, India, and China.

The 600 square meter building, sched-uled to be inaugurated in the first quarter of 2013, will be a mixed-use area for 1,800 employees containing a cafeteria, spaces for cultural and well-being activities as well an area for presentations. It also will be a showcase for Bayer MaterialScience and ECB partners’ technologies. The architectural design is by architect, Roberto Loeb, and was developed with the very latest in sustainable construction features, with special attention to aesthetics and occupant comfort. Innovative technologies will include a reflecting pool connected to a rainwater collection and treatment system, which will maintain comfortable temperature and humidity levels and help to reduce the use of air conditioning, in addition to

providing an aesthetic touch. The building will also utilise thermal insulation and transparent materials, which further contribute to thermal comfort and reduce energy consumption. The exterior perme-able areas will be constructed of wood decking, which will allow the flow of rainwater and allow better absorption by the soil. Furthermore, an innovative automation system will be responsible for the real-time monitoring and manage-ment of all of the building’s water and energy consumption, as well as of the variation of internal lighting according to the daylighting conditions.

The lighthouse will also have LED lighting systems, translucent polycarbonate sheets for better use of natural lighting, thermal insulation of façades and roofs with polyurethane foams, adhesives and low VOC emission sealants, among other cutting edge “green” technologies.

Compared to a traditionally constructed building of similar size, simulation results indicate that the ECB lighthouse will consume 50% less energy and save 70% water. On-site renewable sources of energy will be implemented through photovoltaic panels and solar-thermal systems.The return on initial investment will be achieved within 7 to 10 years, an estimate which also accounts for local climate conditions and overall resource savings. The building will incorporate more durable materials and consume less energy and water throughout its life,

New Facade for Bayer Thai unveiled

Focus

Bangkok – Bayer Thai unveiled a new eco-friendly angulated façade with the 6.5 million baht renovation of Bayer Thai’s headquarters underlines the company’s environmental design principles.

Bayer Thai building, located in North Sathon road, Bangkok, functions as the headquarters of Bayer Thai. Some 400 Bayer employees work in this building in several units and departments. After 15 years serving as the landmark of Bayer Thai, the five story building has under-gone a façade renovation. “The design concept of the project is to create a more modern look for the building, to showcase our high perfor-mance Makrolon® UV-coated triplewall

polycarbonate sheet, and use environmen-tal design principles. These strategies include: improving the efficiency of the building envelope, incorporating daylight and views, enabling a speedy construction process, minimizing waste, and employing energy efficient LED lighting,” said Celina Chew, Managing Director of Bayer Thai.

The Makrolon® UV material possesses a low shading coefficient (0.35), which limits solar radiation and heat gain, and low thermal conductivity and minimal cooling loads. The new façade will create a thermal buffer zone between itself and the existing building.

In order to reduce the waste stream during construction and improve installation efficiency, the design of the façade calls for Makrolon® material sizes that are congruent with those produced during the manufacturing process. The material also achieves an area weight of only 5.0 kg per square meter making installation of the large sheets expedient without the burden

of obstructing walkways and traffic. The entire project is expected to be completed in just six weekends. The last strategy was to choose LED lighting for the Bayer signage and façade lighting because of its superior energy efficiency and long operating life. Com-bined with Makrolon’s durability, this will reduce operation and maintenance costs. Furthermore, the effect of the dynamic light of the LED on the façade material reflects its DNA or life with Bayer’s color code.

Greater Noida, May 16, 2012 – A particu-larly environmentally friendly Bayer MaterialScience office building in India has received the top ranking in the international Leadership in Energy and Environmental Design (LEED) rating system. The zero-energy building in Greater Noida outside of New Delhi was awarded Platinum in the category of New Construction, receiving 64 out of 69 possible points – the highest score anywhere in the world so far.

Located in the industrial region of Greater Noida, some 40 kilometers to the south-east of the Indian capital New Delhi, the building is approximately 1,000 square meters in size and can accommo-date around 40 workstations. This building also serves as a model for customers of a sustainable, climate-friendly building solution.

The building scored the maximum possible points in the categories of Water Efficiency, Indoor Environmental Quality and Innovation and Design. The company building, which opened in early 2011, was built according to the principles of the EcoCommercial Building program, a global network of experts under the leadership of Bayer MaterialScience and dedicated to sustainable building.

Taken over the year as a whole, the building is CO2-neutral. In other words, energy consumption for heating, cooling, ventilation and lighting is covered in full by renewable energy. A photovoltaic system on the roof generates some 88,884 kilowatt hours of renewable electricity each year while the annual consumption of the building is 78,910 kilowatt hours. That is equivalent to a reduction of approximately 81,500 kilograms of CO2 emissions.

The two-story, cube-shaped building was

designed using extensive computer simulations and adapted effectively to suit the local sub-tropical climate. The building is aligned according to the path of the sun and the walls, roof and floors are insulated with polyisocyanurate (PIR) rigid foam to keep the heat out. Over its service life, this material helps save some 70 times as much energy as is needed to produce it and a 70 percent reduction in electricity consump-tion compared with conventional buildings in the tropical region. Highly efficient air-conditioning and lighting systems are also used in the building. What’s more, the ratio of windows to walls has been calculat-ed with great precision, with transparent surfaces making up a good third of the total area.

These technologies and other energy-sav-ing techniques in the building management system contribute to total primary energy savings as high as 42 percent. And so, while these new building costs around EUR 5 , the additional costs associated with the construction of this emissions-neutral eco-commercial building can be completely recovered within a few years due to very low maintenance costs and high energy efficiency.

Symbolic Significance of Bayer ECB program in India

The powerful integration of Bayer’s ECB program establishes an unprecedented interdisciplinary platform for sustainable buildings, particularly in an emerging

country like India that poses great difficulty as up, middle, and down-stream integration in the construction industry is lacking. The materials and expertise of BMS in this field have contributed to an energy-saving and cost-controlling solution that is followed by higher cost-effectiveness.

“The Platinum Award is a clear indication that the concept of ecologically sustainable building can be achieved with the right materials, regardless of whether in the developed world or in an emerging market,” said Thomas Roemer, Head of Industry Platform Building & Construction, Industrial Marketing, Bayer MaterialScience AG. “We hope that we can motivate builders and developers to engage more strongly in sustainable building.”

In the case of the ECB program in India, it is not only the first carbon emissions-neutral building of the year but also validates the notion that ECB program’s methods are applicable in not only cold climate areas such as Europe but also subtropical regions like those found in India. Outstanding building materials such as polyurethane rigid foam made of BMS's quality materials can accomplish both cold and heat insula-tion, with high performance and excellence. Looking to the future, it is exciting to consider the potential impact that Bayer MaterialScience and the ECB program can make in sustainable development in India and throughout the globe.

Great Opportunities

The "Bayer Tongji Eco-Construction & Material Academy" was jointly founded by Bayer MaterialScience, the Bayer Foundation and Tongji University in December 2011. The Bayer-Tongji Eco-Construction & Material Academy, a total five-year investment of EUR 1.5 million, was structured as a direct affiliate under Tongji’s College of Material Science & Engineering. Through this academy, Bayer MaterialScience and Tongji University made joint efforts to promote China’s sustainable construction through education, research and talent develop-

ment projects.

Bayer - Tongji Eco-Construction & Material Academy was opened in March 2012 as expected. It has made good progress in education, innovation and talent develop-ment. It is now in full operation.

Education

Sustainable, economical and efficient energy-saving building has great market potential in China. However, it is urgent that we must provide more training and education for current as well as future industry professionals in order to enhance their understanding and grow their interest in the eco-construction as an emerging industry and increase their expertise.

Education is our top priority. Since the beginning, we counseled and adopted various opinions from professionals in order to make our students apply what they have learned in class. The academy has successfully held four academic courses and seminars by the end of May

since its opening on March 4, 2012. Teachers of the academy are experi-enced experts and professors from Tongji University and Bayer Group, and seniors in the industry; the curriculums rank from the concept of ecological building, design, material, laws and regulations, project management, quality and safety to other specific themes, ways of teaching include lectures, practical training, case analysis, and visit, etc; students of the academy vary from insiders in the industry such as architects, developers, engineers, project managers, and contractors to students and teachers of Tongji Universi-ty. Case analysis and well planned visits to the ecological buildings are the most attracting subjects, which not only allow students to experience the latest design concepts and methods and enable them to explore application examples of ecological materials, but also give them a chance to talk face to face with designers to discuss the areas of further improvement of ecological building and the potential of material function. Both teachers and students benefit a lot. To

make the curriculums more attractive, we do tracking and collect feedbacks. With a high engagement, the teachers and students also raised a lot of valuable ideas. "Both audience and lecturers concentrated on the class. The interac-tions were so passionate that we wanted to go on without stop," Prof. Han Jihong, Deputy Chief Engineer of Shanghai Research Institute of Building Science said with passion after the lecture. Students also spoke highly of the teaching method combined lecture with practice. Feedbacks from students show that the arrangement of curricula is reasonable, and the classes are wonder-ful and vivid with adequate examples in a broad scope. But meanwhile, students expected to add more cases related to daily life and to increase the time of interaction. Cooperation in the industry While the academy concentrates on the work of "education, innovation and talent development", it also takes active part in cooperation within the industry. On April 10 and 11, the academy attend-ed the international forum for green building practical way held by Ecobuild China. From June 13 to 14, the academy will attend the forum for international

The college-en-terprise education model is a new exploration for sustainable development by Tongji and Bayer. After six months of working, the academy is now in full operation and has made good progress, however this is just the start of the project. There are larger amount of more challenging work for us to achieve. We need to continue exploration, practice

and innovation on the current basis. Our expectation is to make ourselves the best partner of the current and future professional training and public educa-tion, formulate a platform for technolo-gy innovation, and build a bridge of ecological building and material field for international exchange.

Command Commissioning – www.commandcommissioning.com.brCase StudyCase Study

As part of its EcoCommercial Building program, Bayer MaterialScience and planquadrat Architects, a renowned German urban planning and design firm, have conducted a study of a sustainable supermarket located in Germany. The simulation predicted that by optimizing energy consumption and intelligently combining modern materials and technolo-gies, the 3,500 square meter retail building could potentially save EUR 60,000 annually compared to a conven-tionally built supermarket, with annual energy costs dropping from EUR 23 to just EUR 6 per square meter. In terms of environmental benefits, the simiula-tion predicted a reduction of carbon dioxide, nitric oxide and sulfur dioxide emissions by at least half. Considering this, the supermarket is set to win the Gold Certificate awarded by the German Sustainable Building Council (DGNB).

The key factor in achieving a totally

sustainable supermarket is adapting an integral plan-ning process right from the beginning, incorporating the inputs of planning experts, future occupants and owners, and product specialists. In this way, developers can determine the optimal combination of building structure, architecture, design and materials. Computer simulations and analyses provide information on future energy requirements and operat-ing costs. These are exactly the kind of services provided by the EcoCommercial Building program (ECB) established by Bayer MaterialScience: product and planning experts from over 65 ECB partners combine their expertise to provide comprehensive planning, there-by supporting developers, investors and planners in creating sustainable buildings.

Supermarket with an unforgettable design

The design of the supermarket developed by the EcoCommercial Building program is very distinctive, rising up from the ground naturally like a hill. The entrance opens to the south and the entire front of the building is a photovoltaic facade. Pools of water in front of the entry area reflect

sunlight to enhance the efficiency of the photovoltaic system. The solar modules are positioned at the optimal angle and integrated into lightweight plastic glazing made of polycarbonate. They simultane-ously serve to provide shade within the building. Because polycarbonate is roughly 10 times lighter than glass, it can generally be installed without the use of heavy machinery. In addition, it requires up to 30 percent less steel for its support structure, which has a direct financial benefit.

The green roof makes the sustainability concept visible for miles around. It contributes to climate control in the interior and to rain water retention. Proven system solutions based on welded lengths of plastic sheeting make the green roof leakproof. The north-facing skylights provide for uniform, natural interior lighting without direct sun. Their back sur-faces can be put to optimal use for additional photovoltaic modules. The multiwall polycarbonate glazing elements are filled with nanogel and combine break resistance with low weight, high transpar-ency and good insulating properties.

the building design, additional artificial light sources are essential. LED technolo-gies can reduce the energy requirement by 75 percent or more in supermarkets. Polycarbonate housings help significantly to extend the service life and efficiency of the LEDs.

Floor coverings are critical to supermarket maintenance

Building maintenance makes up a major percentage of life cycle costs (roughly 80 percent of costs are incurred after con-struction is completed). Important factors include cleaning and maintaining the floor space. Therefore, very careful consider-ation should be given to selecting the right covering. Seamless systems made of polyurethane are highly resistant and easy to clean. The intervals between scheduled maintainance can be extended, and floors can be cleaned faster and with less cleaning agent and water. This cuts costs and benefits the environment. What’s more, the floors are aesthically attractive and available in a number of custom colors.

The EcoCommercial Building program and planquadrat Architects have designed a totally sustainable supermarket with impressive results. As mentioned above, energy costs are 75 percent less than those

Building envelope forms the basis of the concept

The sustainable building concept is based on an energy- and resource-efficient building envelope that incorporates the high-performance insulation material polyurethane. Depending on the applica-tion, it can achieve lambda values of up to 0.024 W/(m*K), enabling up to 40 percent better insulation performance compared to other commonly used insulation materials, or proportionally slimmer superstructures. Polyurethane maintains a high level of insulation performance over decades and, because this material absorbs no water, it need not be replaced even in the event of a leakage. Thanks to its lower specific weight, polyurethane is also seven times lighter, meaning it supports light-er-weight building designs that save on both raw materials and costs.

Conventional heating, renewable energies, LEDs

A pleasant, cost-efficient and ecological indoor climate is created inside the supermarket by effectively combining conventional heat sources with renew-able energies. Heat pumps are combined with thermo-active building systems. Despite the extensive use of daylight in

of a conventional building, with hazardous gas emissions 50 to 75 percent less than the reference values. This is further proof that exceptionally sustainable buildings can be constructed today using efficient system solutions based on innova-tive materials and designs. The basic require-ment is collaborative and comprehensive planning and expert knowledge in a variety of trades and product areas, which are easily facilitated by the EcoCommer-cial Building network.

As the ECB program continues to experi-ence success across Europe and expand its network globally, eyes have turned to one of Asia’s most prominent developed nations: Japan. Foreigners and foreign businesses learned long ago that the Japanese market is very different from others, replete with cultural subtleties and nuanced business practices. The sustainable construction market has proven no different, as localized building conditions and standards are somewhat different from their European and American counterparts.

Building techniques and materials used

vary from place to place based on any number of factors, including but not limited to geography and topography, culture and tradition, and local regula-tions. In Japan, geography is a major factor since much of the land cannot be built upon (about 20% is livable, while 73% is mountains). With such a small percentage of land available for develop-ment, Japan’s real estate developers are forced to build upwards. As a result, many of these structures are quite slim and crowded, often so close that they hardly receive any daylight through the windows. These mid-sized “pencil buildings” are typical of Tokyo and much of Japan’s metropolitan areas.

Japan

Taking into account the challeng-ing conditions of the Japanese real estate market, the University of Tokyo and ECB Japan have worked together to develop a prototype that demonstrates the feasibility of the ECB concept in Japan. In a recent interview, the University of Tokyo Associate Professor Mr. Kawazoe spoke on the difficulties facing Zero Emis-sion Buildings (ZEBs) and the merits of working together with

prototype that demonstrates that the ECB concept is valid even under these demanding circumstances. The University of Tokyo associate professor Mr. Kawazoe was the lead designer and key ECB partner in the development of this building prototype.

Under Prof. Kawazoe’s direction, the design team was able to achieve a marked reduction in energy con-sumption and annual costs in their model. This prototype was created through an integrated planning approach, which took into account later energy demands during early design stages, and an innovative design that included a well-insulated building envelope and energy efficient and energy regenerative technologies.

As this data demonstrates, the prototype is capable of an 80% reduction in energy use and a recovery of the additional investment after 11 years. However, given the relatively short service life of many build-ings in Japan, some clients may feel that the time required to recover their additional investments is too long. Taking this into account, the ECB program has also designed a 2nd version of the prototype, which has left out some of the solutions mentioned in the chart above. Nevertheless, this 2nd version of the prototype still features approximately 65 % energy saving compared to common buildings, and requires only 6 years for amortization – therefore, these prototypes demonstrate the wide applicability of the ECB concept, as designers have a great number of options from which to choose.

E: How far can sustainable construction contribute to climate protection?

K: “In Japan, the energy usage for the operation of buildings reaches over 30% of the entire demand and has been continu-ously increasing. In particular, the energy demand of the commercial segment (e.g. office buildings) is difficult to reduce compared to that of residential housing, where the legal requirements on energy saving have been tightened and systemati-cally reduced, therefore efforts are required.

“The Japanese Government has set the target to reduce greenhouse gas emissions 25% by 2020 and expects all newly con-structed public buildings to mandatorily become zero energy buildings by 2030. However, as a result of last year’s events [e.g. the shut-off of many nuclear power plants in the aftermath of the Fukushima crisis], it has become increasingly difficult to realize the above-mentioned goals.

“Under this situation, architects and engineers must use their full capabilities to design buildings, which feature low energy usage but are still comfortable. The proposed design and technology by Japanese professionals will provide feasible solutions for energy saving to many Southeast Asian countries similar climate zones as Japan which typically have extremely humid and hot summers.”

E: In Japan, in terms of energy-saving, there is very much emphasis on ener-gy-efficient equipment like LED lighting, HVAC etc. (so called “active” measures), but much less on basic design consider-ing the energy demand later on and a well-insulated building envelope. How do you rate these so-called “passive” measures when it comes to the reduction of energy consumption?

K: “As you mentioned, given that highly sophisticated energy saving technologies

as appliances and air conditioning system are already widely applied, the discussion regarding energy saving often tends to concentrate solely on equipment solutions.Of course, because of the [advanced technologies] today and further potential for improvement, it is very important to consider state-of-the-art technology.

“However, the average service life of building structures is estimated to be 47 years, whereas the average service life for equipment is approximately 15 years. Therefore, economically and ecologically, we cannot afford to continue with the current scrap-and-build construction pattern.

“Under these conditions, it is necessary to sensitively design building structures, which have much longer service life than equipment, in order to ensure their longer service life have enough energy saving potential.

“As ZEBs will become mandatory in the foreseeable future, an integrated design process, which incorporates passive as well as active measures in a well-balanced way, is strongly required – to finally realise ZEBs, a combination of sophisticated design, carefully chosen equipment and the utilisation of regenerative energy is

indispensable.”

E: Is the type and location of the virtual prototype typical for Japan?

K: “Tokyo’s Omotesando area, which is deemed the center of fashion and IT industry in Japan, has been chosen as the site for the virtual prototype. Mid-sized buildings, which feature a small floor area and stand close to each other, are repre-sentative for Japanese metropolitan areas. In Tokyo especially we can find this type of urban shape everywhere. It is quite different from Western common practice, but in Japan our office area is relatively small and everything is rather packed.

“Recently, several large-scale redevelop-ment projects have been planned in Tokyo, and many high-rise buildings with large floor areas are being designed by large architectural firms and general contrac-tors. It is said that the energy saving measures in these large buildings are well planned and that reasonable results are being achieved.

“However, small and medium size build-ings, which are owned and managed by separate landlords, are far behind [these large-scale well-funded projects] regarding energy saving and environmental issues

because of a lack of knowledge and financial restraints.

“Buildings like the one chosen for our virtual prototype have considerable problems for reducing their energy consumption. This means that if we provide feasible solutions for these buildings, we can contribute to solving environmental issues in Japan’s large cities.”

E: Can the solutions used within the virtual prototype can be widely applied in Japan?

K: “For the time being, the maximum height for realisation of ZEB is considered to be four floors. The model used by Japanese government authorities is a three floor, center core atrium building, which is favourable regarding energy consumption – but in fact, most of the building sites in urban areas are narrow and condensed as already mentioned.

“In our virtual prototype, by giving hallway and staircase additional functions, we foster the utilisation of daylight, natural ventilation and PV panels in signboard shape, considering both the actual site condition as well as legal requirements. Our proposal can be seen as rather challenging, but well applicable.”

E: How do you rate the contribution that the Eco Commercial Building program could make towards sustainable con-struction in Japan?

K: “Sustainability is a very important concept because of its wide applicability. Conventionally, sustainability has been treated as a subject among experts and they have reached reasonable conclusions But in industrial practice, as a concept it has been treated as contradictory to profitability.

“The ECB program starts from the leading thought that ecology and cost-effective-

ness can exist without conflicts – this is the most unique aspect of the ECB program and different to conventional experts’ thinking so far. I strongly believe that the concept of ECB program has enormous potential to solve our environmental issues.”

E: Is the EcoCommercial Building pro-gram feasible for Japan, too?

K: “Even though the ECB program is based on environmental and energy concerns, it promotes economic activity and tries to harmonize different technologies instead of restricting economic activity. Therefore I expect that it will provide useful ideas in our society.”

the ECB to accomplish energy saving designs for the future.

As the ECB program continues to experi-ence success across Europe and expand its network globally, eyes have turned to one of Asia’s most prominent developed nations: Japan. Foreigners and foreign businesses learned long ago that the Japanese market is very different from others, replete with cultural subtleties and nuanced business practices. The sustainable construction market has proven no different, as localized building conditions and standards are somewhat different from their European and American counterparts.

Building techniques and materials used

The first UrbanTec China Conference at China International Fair for Trade in Services (the CIFTIS) was held in the China National Convention Center (CNCC) from May 30 to 31. Bayer EcoCommerical Building program participated in the exhibition jointly with other network members.

The conference involved key topics such as global smart city trends, market develop-ment, and intelligent investing and financing of technology. Ms. Lucy Shi, Lead manager of Bayer EcoCommercial Building Center of Excellence China developed the speech themed as “the sustainable building achievable today”.

During the two-day gathering, the exhibition of EcoCommercial Building program attracted the attention of Henriette Reker, deputy Mayor of the City of Cologne and Michael Josipovic M.A, deputy Director, head of International Business of Office for Economic Develop-ment, City of Cologne. They showed keen

vary from place to place based on any number of factors, including but not limited to geography and topography, culture and tradition, and local regula-tions. In Japan, geography is a major factor since much of the land cannot be built upon (about 20% is livable, while 73% is mountains). With such a small percentage of land available for develop-ment, Japan’s real estate developers are forced to build upwards. As a result, many of these structures are quite slim and crowded, often so close that they hardly receive any daylight through the windows. These mid-sized “pencil buildings” are typical of Tokyo and much of Japan’s metropolitan areas.

interest in the ECB program and appreciat-ed the achievements of enterprises with international influences like Bayer in actively promoting the development of sustainable building in China.

“Germany is constantly exploring the development of new energy and sustain-able economy. We noticed that China is playing an important role in pushing forward the sustainable development,” said Michael Josipovic M.A. “We firmly believe

that there are vast opportunities for sustainable economic development. We’d like to work with the Chinese government and influential enterprises to further motivate sustainable development.”

prototype that demonstrates that the ECB concept is valid even under these demanding circumstances. The University of Tokyo associate professor Mr. Kawazoe was the lead designer and key ECB partner in the development of this building prototype.

Under Prof. Kawazoe’s direction, the design team was able to achieve a marked reduction in energy con-sumption and annual costs in their model. This prototype was created through an integrated planning approach, which took into account later energy demands during early design stages, and an innovative design that included a well-insulated building envelope and energy efficient and energy regenerative technologies.

As this data demonstrates, the prototype is capable of an 80% reduction in energy use and a recovery of the additional investment after 11 years. However, given the relatively short service life of many build-ings in Japan, some clients may feel that the time required to recover their additional investments is too long. Taking this into account, the ECB program has also designed a 2nd version of the prototype, which has left out some of the solutions mentioned in the chart above. Nevertheless, this 2nd version of the prototype still features approximately 65 % energy saving compared to common buildings, and requires only 6 years for amortization – therefore, these prototypes demonstrate the wide applicability of the ECB concept, as designers have a great number of options from which to choose.

E: How far can sustainable construction contribute to climate protection?

K: “In Japan, the energy usage for the operation of buildings reaches over 30% of the entire demand and has been continu-ously increasing. In particular, the energy demand of the commercial segment (e.g. office buildings) is difficult to reduce compared to that of residential housing, where the legal requirements on energy saving have been tightened and systemati-cally reduced, therefore efforts are required.

“The Japanese Government has set the target to reduce greenhouse gas emissions 25% by 2020 and expects all newly con-structed public buildings to mandatorily become zero energy buildings by 2030. However, as a result of last year’s events [e.g. the shut-off of many nuclear power plants in the aftermath of the Fukushima crisis], it has become increasingly difficult to realize the above-mentioned goals.

“Under this situation, architects and engineers must use their full capabilities to design buildings, which feature low energy usage but are still comfortable. The proposed design and technology by Japanese professionals will provide feasible solutions for energy saving to many Southeast Asian countries similar climate zones as Japan which typically have extremely humid and hot summers.”

E: In Japan, in terms of energy-saving, there is very much emphasis on ener-gy-efficient equipment like LED lighting, HVAC etc. (so called “active” measures), but much less on basic design consider-ing the energy demand later on and a well-insulated building envelope. How do you rate these so-called “passive” measures when it comes to the reduction of energy consumption?

K: “As you mentioned, given that highly sophisticated energy saving technologies

as appliances and air conditioning system are already widely applied, the discussion regarding energy saving often tends to concentrate solely on equipment solutions.Of course, because of the [advanced technologies] today and further potential for improvement, it is very important to consider state-of-the-art technology.

“However, the average service life of building structures is estimated to be 47 years, whereas the average service life for equipment is approximately 15 years. Therefore, economically and ecologically, we cannot afford to continue with the current scrap-and-build construction pattern.

“Under these conditions, it is necessary to sensitively design building structures, which have much longer service life than equipment, in order to ensure their longer service life have enough energy saving potential.

“As ZEBs will become mandatory in the foreseeable future, an integrated design process, which incorporates passive as well as active measures in a well-balanced way, is strongly required – to finally realise ZEBs, a combination of sophisticated design, carefully chosen equipment and the utilisation of regenerative energy is

indispensable.”

E: Is the type and location of the virtual prototype typical for Japan?

K: “Tokyo’s Omotesando area, which is deemed the center of fashion and IT industry in Japan, has been chosen as the site for the virtual prototype. Mid-sized buildings, which feature a small floor area and stand close to each other, are repre-sentative for Japanese metropolitan areas. In Tokyo especially we can find this type of urban shape everywhere. It is quite different from Western common practice, but in Japan our office area is relatively small and everything is rather packed.
