Abstract. In the paper, some approaches to dynamic modeling of heat transfer through external building constructions are presented. The model of heat transfer dynamics through a wall was designed on the base of mathematical describing of an energy balance for the elementary layer of a plane wall. The wall was considered as a continuum with continuously distributed thermal resistance and capacity. Based on the designed analytical mathematical model, a simulation model in MATLAB/Simulink environment was developed. These dynamic models of heat transfer through the wall with real materials parameters and also through the window with real thermal parameters were simulated and some simulation results are presented in the paper.

Keywords: dynamic modeling, mathematical model, heat transfer.
