| Abstract: |
| A measuring system for determination of temperature, moisture, relative humidity, capillary pressure and salinity profiles in building envelopes is presented in the paper. The system makes it possible to analyze the hygrothermal performance of either particular materials or the whole building envelopes in the conditions of difference climate. Both the spatial dimensions of the specimens and the applied exterior and interior climatic data are chosen to be as close as possible to the conditions in the particular building site, so that the system can simulate the hygrothermal processes in the envelopes in quite a realistic way. A sophisticated technology for the determination of moisture, relative humidity, capillary pressure, temperature and salinity in the analyzed specimens based on the application of time-domain reflectometry, mini-tensiometry and mini-hygrometry is employed, which guarantees obtaining reliable data for validation of sophisticated computational models. |
