Original Abstract
The improvement of thermal technical properties of insulation layers is a crucial point of reconstruction of all building objects, in the first place of the large block of flats from the socialistic period in Czechoslovakia, with the aim to extend their lifetime. However, a typical phenomenon of such reconstruction is the occurrence of algae on the outer surface of the new insulation system and conse-quently their surface degradation. This phenomenon can be explained by the night condensation of vapour from porous material structures, driven by the heat radiation. The mathematical model of evolu-tion of temperature and moisture fields is based on the physical laws of conservation of mass and energy. The numerical simulation of this process, coming from the method of discretization in time and from the finite difference method, makes use of the original software, written in the Pascal code. The comparsion of result from numerical simulation and laboratory experiments leads to some recommendations, how to avoid the algae coatings.
