Nowadays we have increasingly important impact on the environment. That can be significantly improved by changing the way constructions are designed and built. After 2020 energy efficient constructions will be the only proper way of designing new constructions.
Thermal bridging represents significant part of heat loss in building envelope. For energy efficient construction, we need building envelope that insures thermal and energy performance. The thesis illustrates thermal loses through foundation slab due to poorly designed and executed details. Nevertheless, we cannot forget the negative impact of frost on foundation slab in winter time, which can produce serious construction damages. To that end the thesis presents findings of new solutions and materials for structural assembly of foundation slab with external wall. For more detailed calculations of thermal bridges, THERM 7.4 software was used, which is based on the finite-element and can model the complicated geometries of building products.
