Sustainable development economy: determination of energy efficiency of private houses on the basis of data on heat gas consumption

In this article the statistical data on gas consumption for heating by private households in the CIS countries are analyzed. The questions of quantitative estimation of heat energy and energy resources spent on heating of a private house are determined. The authors also point out the distribution of private houses for the heating area; distribution of data on gas consumption for heating depending on the period of observation; averaged relative intensity of use of the heating system for the season. The methodology for assessing the energy efficiency of a private house based on average gas consumption during the heating season and the method of conversion of hourly, daily and monthly indicators into seasonal are proposed. As a result of this study, the authors propounded a classification of houses according to their degree of insulation based on data analysis of average monthly unit consumption. The authors of the article came to the conclusion that about 20.5% of the houses that got into the sample have very heavily and even unacceptable heat loss from an economic point of view. It should be noted that the main factor determining the level of gas consumption for heating is the degree of insulation of a private house. It is important to note that the maximum energy saving can be achieved only in the case of integrated approach to heat insulation that is not available economically to all consumers. This circumstance plays an important role in providing energy independence of Ukraine as a guarantee of sustainable economic development.
