The building envelopes with the open air layer are common in building energy-efficient houses. In such buildings, air gap is used for moisture elimination from a surface of external wall, which improves its thermal properties. To improve the thermal quality of building envelopes with open air layer and reduce the heat transfer rate during the cold period, it is necessary to conduct more in-depth study of heat exchange in the ventilated layer of air. The article presents a mathematical model of heat transfer through building envelopes with an open air layer for the cold season. In the proposed mathematical model connective and radiant heat fluxes were considered separately.
