Geometry and Building Technology Guarantee Sustainability

In 2007, E.ON Kraftwerke GmbH, based in Zolling, Upper Bavaria, commissioned the Munich architects Boesel Benkert Hohberg to draw up the energy concept for its administrative building. The goal was to achieve a better office climate and to reduce CO2 emissions. The complex geometry of the building put high demands on the building physics and structural design, which was the responsibility of engineering office Walter Muck. The new administrative building impresses with a form inclined 26 degrees to the south. This makes extra use of non-glare daylight in the north and reflects the heat radiation in the south by making use of physical laws. The building’s heat supply is provided solely by the company’s own remote heat from combined heat and power. An air exchange system with heat recovery, supply air distribution via flexible plastic pipes and a refrigerating machine provide pleasant working conditions and ensure low energy costs.
