Features of the calculation of heat losses through the filling of window openings

The article is devoted to the calculation of heat losses through the filling of a horse aperture. The scheme of formation of the "cold bridge"through the filling of the window opening was presented. Two window designs were calculated and analysed using numerical simulation. It was calculated to reduce the cost of the project by changing the constructive solution. The article examined various ways to take into account the position of the window opening when calculating heat losses. A formula was proposed for the correct calculation of heat losses through the filling of a window opening. Separately highlighted issues that need to be considered in further research. © Published under licence by IOP Publishing Ltd
