Objective. To analyze the problems of implementation of modern energy efficient systems in Ukraine. The advantages of modern technologies over outdated ones are presented. The results of the study should form the basis for the development of recommendations for improving energy efficiency in civil engineering. Problems. Today in Ukraine, solving the problem of energy saving in civil engineering remains a constant priority. Overcoming this obstacle largely determines Ukraine’s recovery from the economic crisis. According to estimates, energy consumption for heating budgetary institutions in Ukraine is 2 … 3 times higher than in the EU countries for the same needs. This is based on the obsolescence of Ukraine’s building stock from the time of intensive construction in the 1960s and 1980s. Analysis. Many countries are already successfully implementing new technologies, materials, and designs that help improve the energy efficiency of buildings. Examples include: a construction concept based on the idea of creating a building that does not require active heating and cooling – a «passive house», the use of SIP panels made from recycled materials, the use of double-glazed windows with «warm edge» technology, the creation of energy-efficient envelope structures such as the construction projects «The Edge», «ZEB Pilot House», «BedZed». Scientific novelty. Analysis of current problems of energy efficiency policy implementation in Ukraine in terms of various aspects, such as legal, economic, technical, social, etc. Cases of successful implementation of energy efficient measures and technologies in civil engineering in European countries are considered. Practical significance. The analysis of the real energy status of the country’s building stock is the basis for the development and support of energy efficiency policy. The considered cases of energy efficient technologies implementation can become an important source of information for Ukrainian construction specialists, which will significantly improve the energy efficiency of new buildings, reduce energy dependence on critical infrastructure, save money for civilians and improve the comfort of living conditions.
