The dimensions of the building were calculated to facilitate reductions in energy requirements. Office buildings are customarily 18 m or 20 m deep. Yet daylight effectively penetrates only the first 5 or 6 metres of office space. It was therefore decided that for Green Office® more than half the floors would be no more than 13.5 m deep: 6 m of office space on each facade, with a 1.5 m wide corridor at the centre. On the deeper floors (18.50 m) the central area is occupied by plant rooms, washrooms, tea rooms, etc.).

The office building ENERGYbase has been erected 2007 by the WWFF Business and Service Center GmbH. The building has 10,690 m² of gross floor area and hosts besides offices also laboratories and a university of applied sciences. Due to the exceptional shape of the facade and a wide range of other measures the heating demand of the building (3.87 kWh/m³y) is 72% below the Austrian Building code. The following measures did contribute to reaching this figure: Building envelope:

Commenting on the Forum launch, Mr. Tom Vereijken – EPE President and Director Water at Grontmij said: "The Forum is a platform which enables the integration of expertise to accelerate the implementation of the estimated 38% cost-effective savings potential in existing buildings by 2020. The Forum will also help member States to coherently implement relevant EU buildings legislation at national level. The Forum will enable front-runners to get successful “bottom up” initiatives into the mainstream.
