The current paper presents an energy storage system that stores the excessive energy, provided by a hybrid system of renewable energy sources, in the form of compressed air and thermal heat. Using energy storage systems together with renewable energy sources represents a major challenge that could ensure the transition to a viable economic future and a decarbonized economy. Thermodynamic calculations are conducted to investigate the performance of such systems by using Matlab simulation tools. The results indicate the values of primary and global efficiencies for various operating scenarios for the energy storage systems which use compressed air as medium storage, and shows that these could be very effective systems, proving the possibility to supply to the final user three types of energy: electricity, heat and cold function of his needs.

Problem statement. The building materials choice is usually based on non-environmental criteria, such asfunctionality, technical characteristics, aesthetics, cost, etc., and the environmental and human health impact is rarely takeninto account. Greenhouse effects, climate change, and energy issues remain a key issue at both European and internationallevels. Today, energy-efficient and eco-friendly areas are gaining more and more popularity in the construction industry, sothe design and construction of energy-efficient and environmentally friendly buildings in Ukraine, considering the worldexperience, including European, remains a live issue today. The purpose of this article is to explore the concepts ofenergy-efficient buildings and so-called "green" construction, as well as to analyze and explore the experience of usingenergy-saving resources in Ukraine and France. Results. Ecological and passive houses in Ukraine, energy-efficient andecological buildings in France, Hitachi technologies have been analyzed. Scientific novelty and practical significance. Theanalysis of the problem of improving the energy efficiency of buildings and ways to solve it allowed to identify ofpromising areas of green construction in Ukraine, which will form the basis for further improvement of methods offormation, evaluation, justification, and selection of rational organizational and technological solutions for energy-efficientconstruction and reconstruction.
