Abstract: Combined experimental and computational approach is used for the analysis of hygrothermal performance of a building envelope on ceramic brick basis provided with the novel interior thermal insulation system. The hygrothermal study is performed in the difference climatic conditions in order to access the hygric and thermal behavior of the interior thermal insulation based on hydrophilic mineral wool. The experimental testing is realized within the semi-scale experiment that presents a logical bridge filling the gap between the laboratory measurements of material properties combined with computational analysis of hygrothermal behavior, and full-scale test house measurements of field variables of heat and moisture transport in-situ. For the experiment presented in this paper, sophisticated semi-scale device is used. It uses the climatic chamber system consisting of two climatic chambers, connected by a specially developed tunnel for testing of fragments of building structures. Here, the fragment of the brick wall with the hydrophilic mineral wool on its interior side is placed into the testing tunnel, and provided with sensors for continuous monitoring of relative humidity, temperature, and heat flux. For the climatic data on the exterior side, the TRY (Test Reference Year) data for Munich are used. Constant temperature and relative humidity is assumed on the interior side.
The climatic loading of the studied structure begins with the climatic data for January 1 and proceeds for 62 days. In this way, the winter period of the year is simulated. The measured temperature, moisture and relative humidity fields are then used for calibration of the numerical computer code HEMOT based on finite element method. Finally, the calibrated HEMOT is used for the long time simulations of the studied structure performance.
