Peneder Holding, a general contractor for business buildings, constructed a new company building in Atzbach in 2010. The office building has an energy performance indicator of 24.8 kWh/m2a. Heating and cooling for the site, where 280 employees work, are supplied by two wood chip boilers of 500 kW each. The cooling of the building is produced by a 420 kW biomass-fuelled absorption cooling machine. The office building is heated and cooled via thermoactive components, using an energy efficient, low temperature heat distribution system. All ventilation systems are equipped with high-efficiency heat recovery units.

The electricity demand is reduced to a minimum by using daylight control, a shading system, presence sensors for the regulation of room climate and a centralised switch-off for all stand-by appliances. Special attention was also paid to comfort and to minimising the maintenance demand of all systems. A total of 20 million Euros was invested in the 8,800 m2 office building.
