Analysis of European regulatory requirements for near to zero energy consumption buildings and the possibility of implementation in Ukraine

Abstract

Efforts are currently being made around the world to mitigate the impact of human activity on climate change. The construction sector is one of the largest sources of emissions. To reduce emissions, buildings must be energy efficient and use a significant amount of renewable energy. NZEB buildings are an important part of our transition to a lower carbon future. Efficient energy consumption in buildings is one of the most affordable ways to reduce the negative impacts of climate change and health-related problems. The purpose of the study is to analyze the regulatory requirements of European countries for NZEB buildings and compare them with the current norms in Ukraine. Determining the cost of energy-efficient structural solutions with current regulatory values. Based on the calculations and research, the following scientific and practical results were obtained. Analysis of norms in European countries for NZEB buildings and compare them with current norms in Ukraine. The calculated design values for NZEB buildings in Ukraine were considered. The needs for insulation of the wall, roof, and basement floor coverings were calculated according to the current norms in Ukraine and the norms proposed by the NZEB. The economic feasibility of measures to insulate the proposed normative options of NZEB was calculated. As a result of obtaining scientific and practical results of increasing the energy efficiency of enclosing structures, it shows that in terms of indicators of enclosing structures, Ukrainian standards are not lagging behind European countries, although they require further improvement and additional changes. The results of the economic calculation of the increase in the thickness of the insulation show that the NZEB standards have a more economic and thermal insulation potential in the long term compared to the current standards in Ukraine. The obtained research results can be used, as an example, in the design or reconstruction of buildings to increase the level of energy efficiency.
