Ukraine is an energy dependent country. The largest energy consumer in Ukraine is the household sector and industry. The technical characteristics of most existing serial buildings in Ukraine do not meet modern requirements for energy consumption. One of the tools to influence the reduction of consumption of construction resources is the introduction into the regulatory framework of requirements for improving energy efficiency. With the entry into force of the Law of Ukraine "On Energy Certification of Buildings", the development of an energy certificate has become mandatory for new buildings, state-owned buildings, local government buildings and in case of attracting public funds for thermal modernization of buildings. The energy certificate is developed by a certified energy auditor and entered into an open database in the Unified State System in the field of construction. The energy certificate contains an energy efficiency class determined by calculation according to the methodology of the national standard, which is developed taking into account European approaches to the calculation of energy
consumption for different needs of buildings. The generalized analysis of the data from the available certificates is of considerable interest for estimating the characteristics of enclosing structures, engineering systems and equipment and the actual and estimated specific energy consumption of different types of buildings. In this study, the authors focused on the energy efficiency of new buildings (starting in 2019). The following indicators of residential and public buildings were analyzed: heat transfer resistance of external walls and translucent structures, specific energy consumption, primary energy, specific CO2 emissions, energy efficiency class. It was determined that the potential for energy savings compared to similar buildings in the European Union is significant, so improving the energy efficiency of the construction sector is an extremely important issue in Ukraine.
