Computer Simulation of the Heat Transfer Process through Multilayer Building Envelopes

The process of non-stationary heat transfer through multi-layer enclosing structures of buildings is considered on the basis of the thermal conductivity equation with asymmetric boundary conditions of the third kind and with an unknown indoor air temperature. The Cauchy problem is considered to determine the change in temperature inside the room over time, which is the basis for the choice of materials for the enclosing structures. Numerical methods are used together with the method of establishment to solve the problem. The modes of heat transfer through various multilayer enclosing structures have been studied based on computer modeling.
