ANALYSIS OF OVERHEATING ZONES FROM REFLECTED SOLAR ENERGY

Abstract

Modern architecture uses complicated forms of facades, including parametric architecture, dynamic facades. Implementing analytical surfaces gives many advantages in construction of surface form, calculation of carrying capacity, prediction of properties of surfaces in different spheres. Surfaces with mirror properties, such as glass with various coatings, as well as polished metal, are increasingly being used as finishing materials for facades. When used as a facade, concave surfaces of zero, positive, or negative Gaussian curvature result in self-intersections of reflected ray surfaces, their coincidences, and concentration, which can lead to energy imbalance. The concentration of energy in certain places must be predicted in order to be able to build a defense against this concentration.

In construction physics, it is important to have a possibility to estimate reflective properties as for sound as light and sun. Such analyze can give not only comfort life around the building but also can prevent serious damage for people and their property. There are known cases of melting cars and burning hair of city dwellers and hotels due to the concentration of solar energy when reflected from the surface of the facades.

The article analyzes the search for overheating zones of solar energy reflected from the surfaces of building facades. Areas of reflected solar energy, according to construction experience, can cause overheating, damage and fire. Due to the construction of analytical surfaces of reflected rays, there are zones of concentration of reflected sunlight as a double line of self-intersection of reflected surfaces. From the energy point of view, it is possible to calculate the amount of reflected thermal energy. Overheating protection is selected according to geometric and analytical calculations.
