Measuring Methodology and Results of Heat-Air-Moisture Performances at Building Envelope Levels

The contribution is focused on the design, selection and implementation of methodologies for monitoring the heat-air-moisture performances at building envelope levels in the experimental chambers. The chambers are located in the outdoor environment - installed samples of building fabrics are exposed to dynamic boundary conditions. Indoors consists of a constantly maintained air temperature and relative humidity - a quasi-stationary state. The chosen methodology determines the purposes of data evaluation and it is a tool for controlling the scientific, theoretical and practical results and conclusions of measurements in real outdoor conditions. The results obtained at an early stage suggest differences of material properties at building envelope levels.
