Title: New company headquarters is first industrial building to meet passive house standard

Xolar, the full-line provider of solar systems, has its headquarters in Europe’s first factory building to meet the passive house standard. The highly dense building shell and the utilization of the earth under the building under the production hall as a heat accumulator along with the special arrangement of the collectors (which provide shade in the summer and allow direct radiation in the winter for warmth) combine to ensure efficient utilization of energy. The annual savings in operating costs compared to similar buildings of conventional design amount to €192,000. This corresponds to an amortization period of 13 years. Annual savings in CO2 emissions come to 185 tons.
