Abstract

Building heating requires up to 45% of all energy resources of this country. The quality and cost of heat supply is the most important condition for social stability and the formation of comfortable living conditions. A level of the thermal energy consumption even in residential buildings of the same type is extremely inhomogeneous. To plan and carry out work aimed at improving efficiency of heat supply of residential buildings, we need cheap and quick tools to identify the causes, having a major effect on the heat consumption of a residential building. Regarding such tool, it is proposed to use the dependence between heat power for heating a residential building and various factors. Source data for the analysis are taken from history logs of common building heat metering stations and data on average daily outdoor temperature and wind speed. When plotting the curve, we used methods of mathematical statistics, building thermal physics and utility networks of buildings and structures. The research revealed that the heating characteristic of the building varied during the heating period, indicating that the specific quantity of thermal energy for heating depended not only on the heat protection properties of the cladding, but also on other factors. The result of the research is a regression equation used to determine the quantity of thermal energy for heating depending on outdoor temperature, wind speed, heating medium temperature and available pressure drop at the input to the building.
