Implementation of RES through the construction of a geothermal heat pump installation and reconstruction of a heating installation at Nursery №3, Burgas

Burgas Municipality (BM) has implemented a number of renewable energy projects in municipal buildings, but mainly solar energy for DHW. On the territory of the municipality, the existing thermal waters in Vetren quarter is mainly used for spa and health tourism, and a reconstructed day-care centre for children uses the mineral waters for heating. Given the limited deposits of thermal waters and in order to increase the share of renewable energy to 32% by 2030, it is necessary to use the existing potential of geothermal energy (Renewable Energy Utilization Program for BM 2021-2030) and one of the goals is to build 30 new installations using renewable energy for heating and/or hot water in municipal buildings. In table 7 of the EE Programme of BM 2021-2030, the building of Nursery No. 3 is included in the priority list of buildings with the highest specific final energy consumption that need to be renovated. The building of Nursery No. 3 has basic EE measures in place and the implementation of the main activity of the project will increase the share of energy from renewable geothermal energy in the final energy consumption of the building and reduce the costs of conventional energy used for heating and cooling. The project foresees the construction of a geothermal heat pump installation for heating and cooling and the implementation of an energy consumption monitoring system. The partner is Norsk Energi, together with the municipality, will implement activities to exchange experiences and best practices in the field of sustainable energy supply and the use of RES. Target groups are 130 nursery children aged 1-3 years and their parents; 43 nursery staff; municipal employees working in the field of Energy efficiency-10. Project implementation will result in 174,7053 kWh/yr primary energy savings; 276.61 tCO2 emissions saved; 171.6 kW installed capacity for heating and cooling, including hot water supply; 234,414 kWh estimated annual energy production from RES.
