ESCO project marks first renewable central domestic hot water system in an apartment block in Bulgaria
Vista Konsulting EOOD is a real estate developer from Burgas, Bulgaria specialising in building and managing energy efficient residential buildings, primarily in Burgas. Their bankers, Pireaus Bank, directed them to the REECL consultants to discuss REECL sustainable energy financing options.
The REECL facility offered an opportunity to implement more efficient technologies to achieve higher energy performance of the apartment building. Under the initial design, the building achieved energy rating of B grade with a specific annual primary energy consumption of 167 kWh/m2. Following the recommendations of the REECL team, the energy performance of the building reached grade A, and improved to 90 kWh/m2.
The REECL team developed a detailed energy model and carried out a comprehensive energy analysis to ensure the completed building met all the REECL eligibility criteria. The Kozloduy International Decommissioning Support Fund (KIDSF) supported the project by providing investment incentives and technical assistance.
The modern energy technologies will save each apartment tenant at least €800 a year in energy costs. The innovative CDHW solution will reduce the cost of domestic hot water by 90% while the new apartment building led to a reduction of the CO2 emissions by 157,773 kg per year.
Mr Stamatov, Vista Konsulting EOOD was very pleased with the results and the opportunity to operate as an ESCO by supplying the tenants with domestic hot water utilising the first renewable central domestic hot water system in an apartment block in Bulgaria.
REECL Facility in Bulgaria was developed by the European Bank for Reconstruction and Development (EBRD) and is supported by the Kozloduy International Decommissioning Support Fund (KIDSF).
