Influence of Modern Facade Coatings on The Value of the Weighted Average Albedo of the Building Façade

When designing buildings, methods are applied aimed at energy saving, with special attention paid to ensuring a comfortable indoor environment. One of the important components of comfort is a sufficient level of natural light, which is normalized by the coefficient of natural light. When calculating the coefficient of natural light, the reflection of solar radiation in the visible range from the facade of the opposing building facing the studied facade is taken into account. In addition, methods are currently being developed to take into account the reflection of solar radiation in the entire range of solar radiation. However, insufficient reference data was found on the reflection of solar radiation in the visible and in the entire range of various facade coatings. In this work, such studies are carried out, and their influence on the value of the weighted average reflection coefficient of the facade in the visible region and the weighted average albedo of the facade in the entire range of solar radiation is determined.
