The use of energy-saving glazing in buildings contributes to the reduction in transmission heat losses and, consequently, energy savings for heating, but it should be taken into account that such glazing reduces the heat input to the building from solar radiation. To determine the feasibility of replacing the glazing in the building with energy-saving glazing, a comprehensive indicator is needed to assess the effectiveness of its application. This paper presents a criterion assessment based on the calculation of heat gain and heat losses for the whole building through filling light openings, introduces the concept of radiation-temperature coefficient of climate and heat transfer coefficient from solar radiation through the window unit. The calculation is made on the example of the building, conditionally located in three cities with different climates, a conclusion about the acceptable use of energy-efficient glazing, except for one option, is drawn.
