Summary
The course deals with building thermal technology (thermal protection of buildings). Students will learn the main thermal technical requirements and computing procedures according to European and Czech standards. They will be able to propose additional measures to improve the thermal properties of buildings and to improve the energy efficiency of existing buildings.
