The results of a comprehensive assessment of the energy, environmental and economic effects from the use of an alternative source of heat supply - a heliosystem, which consists of 180 solar collectors of the SKT 1.0 type, on a natural object - a communal institution "Kharkiv Palace of Children's and Youth Creativity of the Kharkiv City Council of the Kharkiv Region" (CI KPCYC) are presented. The strategy of development of energy sectors of the EU and Ukraine in the period of 2020-2030 was analyzed and significant growth of the relative share of renewable sources in the energy balance of primary sources of energy was noted. In the course of the research, a method of integrated assessment of the efficiency of energy-saving measures was created, which allows to determine the indicators of energy, environmental and economic effects, namely: the absolute and relative value of the amount of saved thermal energy, the value of reducing the amount of fuel, greenhouse gas emissions and pollutants, the magnitude of the reduction in fees for used fuel and the amount of consumed thermal energy. Based on the established methodology, it has been established that the use of the recommended solar system at the on-site facility allows for an additional annual effect to be obtained: energy - additional heat energy - 376.7 Gcal or 20.2%, from which it can be used: 212.3 Gcal or 11.4%, by other buildings (in the period from May to September) - 164.4 Gcal or 8.8%; at the same time, the requirement of the CI KPCYC for heat energy is provided: in the period from May to September - by 100%, during the heating period - by 2.8 ... 35.6%; environmental - reduction of natural gas consumption - 47.7 thousand m3, reduction of CO2 and NOx emissions into the atmosphere - 92.6 tons and 0.101 tons, respectively; economic: reduction of payment for thermal energy - 721.3 thousand UAH; The estimated payback period of the event is 5 years.
