Overview: 

The compilation of Swiss building case studies shows one of the lowest energy consuming buildings in Europe. The projects exhibit integration of innovative passive and active Heating Ventilation and Air Conditioning (HVAC) systems.  The project team used Integrated Design Process (IDP) and of state-of-the-art energy simulation tools for developing project specific energy efficiency concepts.
