The communal and living sector, to the extent that it is the sub-sector of buildings with a majority share of residential buildings, on average, account for approximately 41% of total energy consumption in the European Union. Due to a large share in the total energy consumption, the buildings sector has a significant potential to improve the energy efficiency of existing buildings and thus significantly reduce emission of air pollutants. One way is through thermal modernization. The article

It has been assumed that the energy demand for heating buildings will be limited to the level of 55 kWh/(m2year) for multi-family residential buildings and 60 kWh/(m2year) for single-family residential buildings. The calculations show that it is possible to reduce energy consumption for heating of residential buildings by over 70%, which will result in a reduction of the total air pollutant emissions from housing heating, in relation to the situation in 2011. The article indicates existing reserves in thermal modernization activities and related problems based on the analysis of selected parameters of residential buildings.
