03.11.2014 -> Renovation of Protected Building into an Energy Efficient Business-Commerce Object
The company gained the eco foundation subsidy to renovate a historically protected building from 1972 into an energy efficient business-commerce centre. Since the shell had to stay the same, the thermal insulation was made from the inside and the lower part of the facade was filled with graphite Styrofoam. The renovation process followed the passive house recommendations (PHPP'07). Because of huge heat losses with old glazing, PVC windows and doors were installed. All electrical and mechanical installations were replaced. Energy saving bulbs were installed and a modern control system to optimize the use of electricity was implemented. Instead of heating with oil, the water – water heat pump with five wells was installed. 65% reuse of thermal energy was reached with exhaust air heat recuperator. Solar-tube elements were installed in rooms without windows.
