CREATION AND APPROPRIATION OF THE CONCEPT OF FULL EVALUATION OF ENERGY, ENVIRONMENTAL AND ECONOMIC EFFICIENCY OF ENERGY CONSERVATION MEASURES IN BUILDINGS
Array
Abstract
The concept of an integrated assessment of the effectiveness of energy saving measures in buildings has been created, which allows determining the indicators of energy, environmental and economic effect from the implementation of these measures: the absolute and relative value of the amount of thermal energy saved, the amount of decrease in the amount of fuel, greenhouse gas emissions into the atmosphere CO2 and pollutants, the magnitude of the reduction in fees for used fuel and the amount of consumed thermal energy. An approbation of the proposed concept was carried out with a comprehensive assessment of the effectiveness of using the HERZ Smart Comfort automated system to control the thermal conditions of the premises of a 3-story fragment of the O.M. Beketov National University of Urban Economy in Kharkiv with a total heated area of 225.3 m2. The efficiency indicators of the studied energy-saving measures for the heating period were determined: saving heat energy - 3734 kW·h or 17%, reducing the consumption of natural gas for heating - 406.4 m3, reducing CO2 and NOx emissions - 789.1 kg and 0.86 kg, accordingly, the reduction of fees for the consumption of thermal energy - 4041 UAH and fuel - 4441 UAH. On the basis of the investigated natural object, which was considered as a physical model of large buildings and other types of buildings, the HERZ Smart Comfort system was assessed in the premises of the administrative building (heated area 5821 m2), all buildings of the university (heated area 51186 m2) and fragments of hospital and residential buildings, the heating areas of which are the same as those of a natural object. The results of approbation of the concept of integrated assessment of the effectiveness of energy saving measures in buildings demonstrated its practical suitability and ability to use it when conducting research on field objects, performing mathematical and physical modeling and forecasting.
Keywords: heat consumption, energy saving, natural object, thermal regime, energy efficiency, environmental friendliness, economic effect.
