4. www.solar-info-center.de solar info center In the 70ies in Germany our people didn´t mind to heat all over the whole year, and in summer time, they cooled the buildings at the same time. technical innovations: intelligent regulation systems, including an automatic control sytem for venetian blinds Use of an adiabat cooling system, which works by spraying water into the ventilation system to get a cooling effect free cooling ventiliation during the night in some parts of the building, which means to cool the building during the summer by raising the ventilation with fresh, cool air from the outside. To use this method you need heavy walls, ceilings and other materials inside to have temperature stores like cooling batteries in ice boxes. total energy saving: about 60 % !!

5. solar info center Building conception: Reduction of the space heat requirement Installation of a thermic protection insulating glazing in the restaurant as well as an internal insulation in the bar and guest area. Improvement of the room air Source ventilation: the fresh preheated supply air expands within the base range into the guest area, continues to warm up by internal heat loads and presses up used air into the air exhaust duct. > best air conditions with optimized change of air Reduction of the ventilation losses by ventilation heat recovery in the bar with a recuperation grade of 95 %. Reduction of the ventilation losses in the kitchen by use of ventilation equipment with direct admission of fresh air into the exhaust air caps: > optimal kitchen ventilation with smallest losses of energy over the exhaust air.

23. www.solar-info-center.de solar info center no Extra costs The Solar Info Center is financed on a private basis and has to work economically independent. Integral Planning saves investment and operating costs. Energy optimized building is economic, environmentally freindly and comfortable for the user.

24. www.solar-info-center.de solar info center Day light and Shading Tageslicht- quotient in % 3,0 0,9 Tageslichtsimulation Verschattungsstudien Active simulation during planning bright office space through intelligent planning No overheating in summer because of systematic shading systems The adjustment control of the blinds reacts on temperature as well as individually for each office unit

25. www.solar-info-center.de solar info center Automatic Ventilation Exhaust air ventilation, in combination with air intakes in the walls, assure constant fresh air Cooling in summer through night air cooling The massive walls store the cool temperatures from night into the day No suspended ceilings Büros 5.OG Büros 4.OG Büros 3.OG Büros 2.OG Büros 1.OG Abluftventilator (2 je TH-Kern)

26. www.solar-info-center.de solar info center Rainwater concept The courtyard is full of plants. The whole rain water of the site can drain away on the planted areas. The draining water meets the ground and goes through pipes down under the basement where it can drain away.

27. www.solar-info-center.de solar info center Minimized Energy Consumption 20 cm thermal insulation on the external walls and roof Thermal insulating glazing, U=1,2 W/m²K The need of thermal heat of the Solar Info Center is 29,8 kWh/m²a and about 30% below the by law permitted need. It is a so-called 3-Liter-House.

28. www.solar-info-center.de solar info center Reduction of Emissions There is a pipeline running through the site coming from the district heating system network at the university hospital. We use the pipeline and receive the heat from a newly installed heat recovery system at this district heating system The production of the thermal heat is emission-free by 100%.

29. www.solar-info-center.de solar info center Contracting The Solar Info Center finances part of the heat recovery system by contracting The heat recovery system delivers more energy than the Solar Info Center needs No additional cost for user and investor compared to conventional system because of the reduced energy consumption of the building.

30. www.solar-info-center.de solar info center Cooperation and competition Cooperation between the different firms in the SIC is everyday life New common projects Positive competition Quick and efficient contact with experts

31. www.solar-info-center.de solar info center Innovation and established concepts The building concept of the Solar Info Center combines mature technologies with the state of the art The applied concept reflects actual economic solutions but in some parts of the building, research and development of new technologies never stops (PV-Tec, Concentrix, PSE)
