Thermal Protection of Buildings
FAST-BH10Acad. year: 2012/2013
Proper design of thermal technical properties of building structures, rooms and buildings ensures the prevention of thermal defects and failures, ensuring the desired state of the internal environment and low energy performance of buildings. In addition to thermal and moisture microclimate can be optimized design of the structure and the doors and windows also provide the required acoustic microclimate. The optimal design size and type of window pane can affect the thermal, acoustic and visual comfort in the interior and the overall energy balance of the building.

Learning outcomes of the course unit
Students in the course learn to perform basic thermal technical calculations. This knowledge will help them to properly design structures so as to meet the thermal and technical requirements for the design and verification of buildings with the state of the internal environment. In addition, students on the course will help in the design of structures in terms of elimination of thermal defects or failures and design of the building envelope in terms of heat transfer through the building envelope.
The students also learn to assess whether the conditions inside the building thermal comfort.
In addition to these skills will graduates of this course overview on the principles of designing buildings with low energy náročností.Také them will be briefly explained the basic principles of design of structures and buildings in terms of acoustic and visual comfort.
