Originální abstrakt

Energy building design concept consists in controlling the thermo physical characteristics of the building envelope such as thermal transmittance (U-value) to name one example. However, besides the U-value, the envelope thermal inertia should also be considered because it helps to create indoor thermal comfort. Therefore, in situ measuring and dynamic thermal simulation was made. Simulated calculation results were validated by measuring. In the same model were created cases. These cases varied building envelope constructions, which had different materials and thickness, but they had the same U-value. The aim of this work was to compare simulated cases and to understand, how it works. It was found that the variation of outside temperature have no significant influence. Different performance of the building envelope constructions was seen only when heat gains were considered.
