Analysis was conducted in order to check, whether the shape of glass or metal façade that reflects light can affect the size and intensity of reflected solar glare (RSG). RSG "occurs when bright beams of light bounce off of smooth surfaces into people’s visual cone or onto surfaces" (Perry, p. 1592160). This optical phenomenon might affect large area and increase heat load on other objects (buildings, cars and humans). Boundary of Reflection Area (BRA) was
