Dresdner Bank, Freiburg In the 70 ies in Germany our people didn´t mind to Dresdner Bank, Freiburg In the 70 ies 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 % !! solar info center www. solar-info-center. de

Brauhaus Riegel Building conception: Reduction of the space heat requirement Installation of a thermic Brauhaus Riegel 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. solar info center www. solar-info-center. de
