Energy Balance of AAC Building Envelopes with Mineral-Wool Thermal Insulation: Effect of Moisture Content

摘要

Computational analysis of hygrothermal performance of several building envelopes based on autoclaved aerated concrete (AAC) is presented in the paper. Based on the knowledge of thermal and hygric conditions inside the building envelope, the energy balance calculations assuming the effect of moisture content are accomplished. All the material parameters necessary for the calculations are measured within the experimental analysis preceding the computations. As boundary conditions, climatic data in form of reference year are used. The obtained results are compared and conclusions are drawn.
