THE VALUE OF A RATIONAL ROOF OVERHANG OVER A STAINED-GLASS FACADE USING BIM TECHNOLOGIES

Abstract

Problem statement. These days, the issue of reducing energy consumption is relevant, including due to the roof overhang formation in winter, when the sun is below the horizon and can use solar heat for heating, and in summer, when the sun rises high above the horizon and solar radiation is maximum. The issue of roof overhangs value therefore becomes relevant in reducing energy consumption. The purpose of the article is to determine the rational roof overhang value to reduce energy consumption and the dependence between stained-glass system height and roof overhang value using Revit software. Conclusions. The roof overhang value can make a significant difference to a building's energy consumption during the heating period, allowing solar radiation to enter the house due to the large open areas of the stained-glass windows. In the summer, for example, the roof overhang can provide shade inside the house during the hottest times of the day, thereby reducing the energy consumption for air-conditioning cooling. The dependence between the height of the stained-glass window and the rational roof overhang value, which provides shade inside the room in summer and does not prevent the sun's energy from entering the room in winter, was determined.
