| 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. |
| Learning Outcomes of the Course Unit |
|---|
| Student will acquire basic knowledge and skills in building thermal technology. He will learn to assess structures and buildings according regulative and standard requirements. He is able to solve elementary computational tasks using approximate and exact methods using special softwares and he will get the ability to design and evaluate the building structure in terms of thermal technical requirements. |
