Analytical Method of Calculation of the Reflected Solar Radiation From the Facade of the Opposing Building
In normative documents the calculation of heat input in the building from solar radiation is presented without the influence of development. Meanwhile, in the presence of an opposing building, there may be additional heat gain from solar radiation reflected from the opposing façade to the studied façade. This article proposes a method of calculation of the reflected component of solar radiation from the façade of the opposing building. It discusses the theoretical basis of this method, is adapted to construction practice due to the coefficient of reflected solar radiation calculated for various parameters of the building. The calculation is held by the formulated method for the heating period on the example of the building in the presence of the opposing building, the results are analyzed and the necessity of the influence of the opposing building on the heat gain of the reflected component of solar radiation is shown.
