Extensive experimental investigations have been carried out in the passive house in Boruszowice for several years. The building foundation interface consists of a 25 cm reinforced concrete slab situated on a 40 cm layer of Styrofoam. The analysis of experimental results as well as theoretical calculations made it possible to determine the thermal performance of the applied slab on grade with floor heating during the whole yea.
