Assessment of the Impact of Climate Change on the Energy Efficiency of Climate Control Systems of Buildings

The relevance of the study is related to the need to take into account climate changes in order to predict the structure of the building’s energy balance. The subject of the study is the dependence of energy consumption by building microclimate systems on the increase in the average annual temperature in the construction area. The purpose of the study is to estimate the total energy consumption for building climate control under conditions of a set degree of climate warming. The task of the study is to obtain a mathematical description of the annual change in outdoor temperature and analytical expressions for the duration of the heating and cooling periods and the degree-days for these periods. The representation of the annual course of the ambient air temperature in the form of harmonic oscillations with a certain average value and amplitude is used. By integrating this expression within the necessary limits, the dependencies for the degree-days of heating and cooling periods are obtained. Calculations based on these dependencies were made for the climatic conditions of Moscow within the limits of an increase in the average annual temperature by two degrees, and the results were analyzed. It is shown that under the conditions of the studied variant of climate parameters change, the decrease in energy consumption for building heating and heating of the inflow during the cold period is more significant than the increase in the consumption of cold for cooling in the summer. Therefore, under the conditions of Moscow, climate warming can lead to a decrease in the total annual energy consumption for providing the building’s microclimate.
