| Summary |
|---|
The course Building Environment focuses on the theoretical and practical principles of thermal and humidity behavior of building structures and buildings. It introduces students to the basic laws of heat propagation, thermal properties of building materials and requirements for thermal comfort of the indoor environment. Emphasis is placed on thermal and energy assessment of buildings in accordance with applicable standards and legislation in the Czech Republic and abroad. The course also includes an introduction to the basic principles of assessing the energy performance of buildings and the application of sustainable materials and modern construction solutions, including green facades.
Learning outcomes:
- the student will explain the basic principles and laws of heat, moisture and air propagation in building structures and buildings, thermal properties of building and insulation materials, principles of thermal comfort of the indoor environment and their mutual connections, basic requirements of standards and legislation on thermal and energy properties of buildings,
- applies the principles of thermal and energy assessment of buildings and their parts, calculation procedures for determining thermal requirements, principles of design of additional insulation and suitable composition of structures, principles of sustainability in the choice of materials and structural solutions,
- compares the results of energy assessment of residential, civil and industrial buildings, differences in the design of perimeter and roof cladding in the Czech Republic and abroad, including the influence of green facades. |
