We can note that the centralized thermal energy supply systems provide about 95% of the population of Chisinau and 90% of the population of Balti. In 13 other localities, the centralized systems have been fully or partially restored, but they deliver heating agent to a limited number of the population, ensuring practically only objects with a social purpose. Coverage area of centralized systems The construction sector accounts for about 45% of the total energy consumption in the Republic of Moldova, followed by the transport sector with 23% and the industry sector with 10%. The construction sector is in continuous expansion, which will inevitably lead to an increase in energy consumption. A large part of the housing stock, totaling 78.9 million m2, is between 20-60 years old, its thermal characteristics being low. The potential of reducing the consumption of an old building is estimated between 30 and 50%. The construction sector is responsible for achieving energy savings of approximately 10-12% in the national target of 20% by 2020. A significant part of the energy consumption belongs to the housing fund. Accordingly, greenhouse gas emissions in this sector are also significant. An important feature of the sector in question is the waste of energy. At the same time, compared to other energy-consuming sectors, the final energy users in the housing sector are characterized by the greatest potential for energy conservation. Increasing energy efficiency in the residential sector can be achieved by ensuring the reduction of energy consumption, without compromising the well-being of tenants or the environment.
