Computational and experimental characterization of building envelopes based on autoclaved aerated concrete

摘要

Hygrothermal performances of three types of building envelopes based on autoclaved aerated concrete (AAC) provided with different thermal insulating materials (expanded polystyrene, hydrophilic mineral wool, AAC with extended thermal insulation capability) are compared. The simulations are accomplished using the computer code HEMOT based on the finite element method. Results of the simulation are the moisture and temperature fields across the building envelope, which in combination with mechanical parameters present a sufficient data source for service life analysis.
