Дослідження ефективності використання природоорієнтованих технологій під час проведення енергомодернізації будівель

Abstract

The article considers technologies for ensuring comfortable indoor conditions during hot weather and reducing the negative impact of heat waves on human health. It is established that the most common technologies for ensuring comfortable conditions require the use of modern high-tech equipment, significant material resources for the purchase and installation of equipment, and ensuring its operation. It is proposed to use vertical landscaping with vine-like plants to reduce the intake of excess heat in hot weather, which in the warm season can cover the walls with a dense layer of foliage and protect them solar radiation. The exterior envelope of the buildings, which are oriented to the south, east, and west, is to be decorated. The object of research is a red ceramic brick building located in Kharkiv, part of the walls of which are densely covered with the deciduous vine Campsis. Experimental studies of the temperature of the outer surface of walls of different orientations, with and without vertical landscaping, were conducted on cloudless hot days in July-August 2023. The algorithm has been developed for calculating the reduction of excess heat in a room during hot weather as a result of the use of vertical landscaping. To determine the temperature of the outer side of the wall, the equation of energy conservation in the form of a heat balance under the conditions of a quasi-stationary process was applied. Comparison of the results of experimental studies and calculations confirms the possibility of using this calculation algorithm. The effectiveness of the use of vertical greening is confirmed on the example of the ed research object. Excessive heat entering a room in a house through a 15 m2 wall facing south during a 7-day "heat wave" under the climatic conditions of Kharkiv decreased by 19.7 kWh, or 2.5 times.
