As part of a research project supported by the Swiss Federal Office of Energy (SFOE) and in collaboration with representatives from the enforcement authorities (EnDK, EnFK, Minergie, AHB Zurich), universities, SIA and planning offices, Building Simulation Switzerland was able to develop specifications for the documentation for official verifications with building simulations.

This QSSIM project (quality assurance of thermal building simulations for official verification) aimed to increase the acceptance of building simulations as a verification method among all those involved. To this end, specific tools were created that can support the inspection authorities, planners and clients in recognising or ensuring a high-quality simulation.

The tools developed are a catalogue of criteria with the associated guidelines, in which the requirements for thermal building simulations for the most common verifications and the input and output data required for the verification are defined. These requirements are illustrated in three sample reports.
