1. REYNAERS, KEY DRIVER IN SUSTAINABLE BUILDING INNOVATION The time is right Fact. Buildings represent up to 35% of total energy consumption. Recent studies have shown that by 2030 energy used in building and construction can be reduced by up to 45%*. This means buildings can become a major force in reducing energy consumption. At Reynaers we truly consider sustainability as one of the fundamental trends in the building industry. Therefore we do not only systematically improve thermal insulation of our products but also integrate green technology in our solutions. Building Integrated...

2. THE FUTURE IS SOLAR ENERGY a. What are photovoltaics? Photovoltaics (PV) convert solar energy - sunlight, including ultra violet radiation - directly into electricity. With the rising demand for clean energy, their production has been doubling every year since 2002, making it the world’s fastest-growing energy technology. Solar power is pollution-free when used. PV hardly need maintenance and their efﬁciency is rapidly rising while mass production costs are falling. b. An industry destined to grow The PV industry boom is forecast to continue in the coming years. If local and...

c. The importance of political commitment There is a clear commercial and political commitment to the expansion of the PV industry. Thanks to its feed-in tariff program Germany has developed the most dynamic solar electricity market in Europe. Many European states have also implemented feed-in tariffs and have adjusted it to their needs.

3. OUR ANSWER IS BIPV a. What are BIPV? Building Integrated Photovoltaics (BIPV) combine the best of both worlds: as multifunctional solar products they generate electricity through photovoltaics while serving as construction materials. BIPV can be parts of a building’s envelope, like roof cover, wall facing and glazed surfaces. They can be solar protection devices like sunshadings, additional architectural elements such as canopies, balcony parapets and any other architectural element of a building. Today’s BIPV products come in all shapes, colors and functions. They are affordable,...

c. Types of PV panels In photovoltaic modules, the absorber converts sunlight into electricity. Mono and poly crystalline cells are the most well-known absorbers. ■ ■ Mono crystalline cells: yield 18% - 180 Wp/m² Poly crystalline cells: yield 14% - 140 Wp/m² Crystalline PV can be applied as non-transparent panels with an average yield of 120 to 180 Wp/m². As semitransparent PV you get an average yield of 50 to 100 Wp/m². ■ Amorphous cells: yield 8% - 80 Wp/m² Amorphous silicon cells may be less efﬁcient than crystalline cells, but they are cheaper and that makes them more suitable for...

d. Effective design When designing the integration of PV into a building, it is vital to orientate the panels towards direct sunlight. The balance between the shading capacities of semitransparant systems and providing an ofﬁce with maximum daylight is crucial for visual comfort. By calculating the shadow angles of a building’s façade you can determine the optimal position of a panel. Depending on your position and the season, shadow angles logically differ for different cities. As shown in this graph, the orientation of the building as well as the angle of the panels are crucial to...

This sun blind matches electricity production with protection against blinding and direct sunlight. Filling type double glass, glass/Tedlar and standard panels This type of sun blind consists of a series of different PV panels that are suited for every building, existing or new. Both practical and attractive, it protects against sunlight and avoids blinding. Filling type double glass, glass/Tedlar Non-insulated solution suited for renovation projects or new roofs, for hangars e.g., this is a great alternative for classic roof systems because they generate electricity. Filling type double...

5. PROJECTS CW 50-HL with photovoltaic panels Universitat Ramon Llul, La Salle Barcelona, Spain, 2006 The La Salle Technological and Business Innovation Park building is located in Barcelona’s uptown. The façade structure is a combination of iron and the CW 50 Reynaers Aluminium system that sustains 650 m2 of glass surface. The surface includes 195 m2 of solar panels that generate 90 mW hours per year, enough energy to illuminate 2,5 km of city streets for one year. The creation of a curtain wall as support on the photovoltaic façade allows the hot air accumulated in the air chamber to be...
