Geometric Basis of the Use of “Green Constructions” for Sun Protection of Glazing

Abstract

Sun shading is one of the possibilities to rise energy efficiency of buildings. Green structures that combine structures of buildings with living plants are biotechnical elements of buildings. They can rise energy efficiency of buildings. One of the useful properties of the green constructions is sun shading possibilities especially for terrace greening. The most radical method is using the vertical façade greening, which can fully shade glazing. The main problem is that the glazing cannot perform its main function—looking through it. The terrace greening can provide the most natural shading as in a park. Impossibility of full shading gives the necessary insolation of rooms in the most of cases. In this work, there are recommendations for design of the constructions for the Sun shading. There are recommendations for plants assortment, algorithms for analyzing of the Sun position for this purpose and an example for building the figure around glazing for filling it by the plants.
