“…Currently, Ukraine has signed memoranda with foreign countries, in particular with China and Iceland, on cooperation in the field of geothermal energy and research into the geothermal potential of Ukraine, and the development of geothermal energy takes place only at the research and industrial stage (Yurkevych et al, 2022).…”

“…The geothermal waters of the Lviv region are characterized by a temperature of 90-95°C, a mineralization of more than 30 g/dm 3 , and a high content of hydrogen sulphide (Ivanov et al, 2022;Yurkevych et al, 2022). It is advisable to consider the possibility of using these waters to generate heat, in particular for heat supply systems in housing estates.…”

“…For the parameters of the well, such as: reservoir diameter equal to 500 mm, energy recovery factor 10% and the well's exploitation period of 50 years, it was determined that for a 1 MW installation, the area should be approximately 2 km 2 during year-round operation. of surface depending on the formation temperature (Yurkevych et al, 2022) When developing geothermal heat supply systems of the Lviv region, the maximum value of the coefficient of efficiency of thermal water intake should be ensured. The value of the coefficient depends on the type of heat energy consumer and amounts to: for the heating system -0.05-0.34; for the ventilation system 0.15-0.45; for a hot water supply system -0.7-0.92.…”

The development of energy based on RES is an important element of the policy of sustainable development and maintaining energy security. The difficult situation in the energy sector is turning more and more countries towards alternative energy sources. The feasibility of obtaining energy from renewable sources is linked primarily to the resources that are also economical. The main advantage of geothermal waters is that they can be used to produce heat or electricity, regardless of the time of day or climatic conditions. Data from geological research allows us to conclude that both Ukraine and Poland have favorable conditions for the use of energy from low and medium temperature geothermal waters. Ukraine is also turning to the possibility of using geothermal energy to produce electricity. Examples highlighting the possibility of using the energy potential of geothermal waters in the Lviv region and the Czestochowa poviat were presented.

The introduction of renewable energy sources makes it possible to expand the possibilities of development of branches of the national economy, in particular heat energy, to accelerate economic growth and reduce the release of greenhouse gases into the environment. Spatial analysis of renewable energy sources contributes to their effective use and allows for planning the local development of renewable energy. In this article, a spatial analysis of renewable energy sources in the Lviv region, such as wind energy, solar radiation, fuel wood, agricultural animal manure, and sewage sludge, is performed. It was established that the most promising district in terms of the availability of renewable energy sources is the Stryi district, since the amount of solar radiation and the amount of forest land in it are higher than the same indicators for other districts, in addition, the amount of sewage sludge is also one of the highest in the region. For the possibility of increasing the total share of renewable energy sources, the districts of the region can cooperate with other districts of both Lviv region and neighboring regions.

In this article the specific heating and cooling capacity of the ceiling TABS was determined. The step of tube laying varied and was 10, 15, 20, 25, and 30 cm. Determination of the specific heating capacity was carried out for th /tc = 35/31; 36/32; 34/30 oC. The determination of the specific cooling capacity was carried out for tcold /theated = 15/18; 16/19; 16/20oC. The radiant heating system based on ceiling TABS allows providing the necessary heating capacity to fully cover the heat loss of the room. The maximum values of the carrier temperature are th /tc = 34/30 oC. In the warm period, the ceiling TABS does not allow to provide the necessary cooling capacity of the room. Thus, the greatest cooling capacity of TABS is observed at coolant parameters tcold /theated = 15/18оC, which allows covering about 70% of the estimated heat gains of the room. Therefore, during the hours of peak heat gains an additional cooling device should be used in the room.
