Studies of the reflective properties of glazing with energy-saving coatings

Translucent facade systems with a high percentage of glazing are currently being designed. During the warm season, buildings with such facades experience overheating of the premises and increased energy costs for air conditioning. Energy-saving glazing with various coatings is used in such facades to regulate heat gain from solar radiation. Energy-saving glazing reflects part of the heat gain from solar radiation both in the cold and in the warm season. In the construction calculations of the coefficient of natural illumination of the premises of buildings, the reflective properties of the facade decoration are also taken into account. Domestic and foreign researchers are developing methods that take into account the influence of the reflected component of solar radiation on heating and lighting of rooms. Due to the fact that data on the reflection of solar radiation by energy-saving glazing are widely used in these calculations, it is necessary to update the background information on their properties in a timely manner, as well as to have an indicator for assessing the applicability of a particular type of coating in a given climate, which is considered in this paper.
