A METHODICAL APPROACH TO REDUCING HEAT ENERGY EXPENDITURES FOR BUILDING HEATING

Abstract

The work provides a method of preventing the consumption of heat energy for heating the building. It is noted that the energy statistics of Ukraine foresee an increase in the use of primary energy resources in the period 2020–2030 mainly due to energy saving, which, in turn, will ensure a 30-40% reduction in emissions of harmful substances into the atmosphere and stabilize greenhouse gas emissions. In order to substantiate the ways of reducing money costs for electricity and heat consumption, certain measures are proposed in the work, which demonstrate the greatest economic effect in the shortest time. The evaluation of the quality of thermal protection of the building's enclosing structures was carried out. The analysis of thermograms of enclosing structures based on infrared scanning of surfaces is presented. The thermal imaging survey was carried out in two stages. With the help of a thermal imager, at the first stage, a scan of the enclosing structures was performed in order to identify areas of the enclosing structures that have different temperature fields. Based on the analysis of the thermograms of the previous scan, a program of detailed examination of the areas with temperature anomalies is planned and the reasons for their appearance are clarified. Based on the conducted research, recommendations are given to increase the combined heat transfer resistance of enclosing structures in order to prevent heat energy costs for heating the building.
