Estimation of Insolation of the Mirror Hall of a Unique Building

Abstract

For studying of insolation of architectural objects with mirror walls, reflected solar radiation shall be accounted for. Most ways of insolation duration estimation are based on geometry of visible solar path, namely the geometrical model of the process of insolation of a point of Earth surface. This model is the daily cone of sunrays. At the same time, there is a daily cone of reflected sunrays in a point of a reflective surface. Using this model, insolation of a mirror reception hall in a unique building in the Russian South was studied. Geometric modelling has shown that on the floor of the hall of mirrors in some areas there is an addition of three reflected from the faces and the corresponding direct beams of solar radiation. The shots made by means of the thermal camera testo 882 have confirmed reliability of the proposed geometrical model.
