Abstract: Nowadays energy- and comfort-conscious design approach of buildings necessitates the development of the masonry blocks as well. The building blocks with different internal structures and various fillers are rapidly spread the market. The study deals with heat and moisture migration problems within these blocks. The aim of the research is to analyse selected 30 cm, 38 cm and 44 cm thick hollow and filled ceramic masonry blocks, using different filler materials, such as stone wool, expanded perlite and polyurethane foam. The comparison based on multi-dimensional HAM simulations of the building blocks, in which case the material properties are specified by laboratory tests. The steady-state models are compared to measurements and simulations performed on masonry blocks’ sections also. For the transient conjugated heat, air and moisture transfer simulations, different climate conditions (Budapest, Espoo, Lisbon) across Europe are used. During the research, 4 different masonry block types and 5 different fillers were analysed and compared.
