In-Situ Monitoring of the Effect of External Environment on a Contemporary Building in Prague: The Performance of the Additional Thermal Insulation System

摘要

Experimental assessment of the hygrothermal performance of an office building in Prague, which was recently provided by an additional contact thermal insulation system (TIS), is done in the paper, in order to evaluate the contribution of the applied TIS to the moderation of the interior climate. At the long-term in-situ analysis of the building, the measurement of relative humidity and temperature profiles along the cross section of a selected part of the building envelope is carried out. The measurement is realised for 1.5 year on the non-insulated wall at first, and after the application of the exterior TIS it continues for another 1 year. The obtained results show an improvement in the hygrothermal function of the analysed building envelope due to the application of TIS that reduces significantly the thermal response of the investigated building to the changes of environmental conditions.
