The construction of the Edward-Steichen-Gymnasium, commissioned by the Administration of public buildings and planned by Jonas Architectes, is integrated into the state of Luxembourg's concept for sustainable building.

The total primary energy demand as well as the environmental impact in terms of CO2 emissions is equivalent to class A. It is therefore a highly efficient building.

The materials used comply with the principles of sustainable development: the thermal insulation of the envelope is made of recyclable materials such as mineral wool and wood fibre panels. 

The provision of natural light reduces the operating hours of the artificial lighting.

The grey water recovery system from the showers for the toilets and the recovery of filter water from the swimming pool are also installed in the building.

An intelligent control system for the blinds reduces the heat input in summer and reduces the primary energy requirement for cooling energy.

Drees & Sommer supported this project with Commissioning Management.
