Special Award for GRABAND Headquarters

The special prize has an honorable place on the reception counter.

The contribution we participated with in »Energetische und bauliche Sanierung eines Bestandsgebäudes Baujahr 1970« (energetic and structural renovation of an existing building built in 1970) was awarded with the special prize in the competition resource efficiency for the region.

The jurors praised the multiple measures applied in the comprehensive renovation of the building: Geothermal heating and a cooling system with heat pumps and depth probes, into which the exhaust heat of our server cooling is also fed into as well as the automated ventilation system with heat recovery, the use of the no longer required and cleaned underground (heating) oil tanks as a water storage for rainwater utilization and an infiltration system, additional internal insulation of the building, the design of the windows and the glass front with a three-pane heat and sun protection glass as well as LED lighting for the entire interior and exterior area. Additionally recycable material and bricks from the demolition works were reused or sold for recycling. Altogether we could save about 72 percent of bricks and tiles through various measures.
