Renovation of a school from the 1950s to plus energy level

The Uhland school in Stuttgart was undergoing renovation to plus energy level during the last 2 years. Now, the construction work is completed and the pupils and teachers can move back into the main building of the school at the beginning of 2017. The building envelope was insulated with high-efficient expanded polystyrene (EPS). On top of the basement slab and at the gable walls vacuum insulation was used. The new windows are triple glazed. All classrooms were equipped with CO2-controlled decentralised ventilation units with heat recovery.
