Abstract
Energy efficiency is a very important factor in the Building sector. Building sector consumes about 40% of the world total energy. At present, new buildings in Poland and other European countries are designed according to very strict requirements. The problem arises when we take into consideration large number of the existing buildings. These buildings, especially the ones built in the last century, consume a lot of heating energy. Thermal protection requirements for the existing buildings subjected to thermo-modernization are specified in the technical regulations. Thermal protection requirements for thermo-modernized buildings in different countries are different. In Poland, a thermos-modernized building must meet the requirements for thermal protection of external partitions. In Ukraine, the requirements of thermal protection are modelled on European regulations. In Ukraine’s, thermos-modernized buildings must meet the requirements for thermal protection of external partitions and primary energy requirements. However, in Poland thermo-modernized buildings do not have to meet the requirement for a non-renewable primary energy factor – EP. [kWh/(m2y]. The existing buildings do not always have the option of converting a non-renewable heat source into renewable heat sources. In the article, the authors presented the energy analysis of adapting an existing building to the current technical requirements in Poland (WT 2017) and to the level of requirements for buildings of "almost zero energy consumption NZEB" (WT 2021) and adapting an existing building to the current technical requirements in Ukraine.
