Programme: Development of Regions Programme 2021-2027

The project proposal includes introduction of energy efficiency measures and provision of an accessible architectural environment to the entrances of a residental building block 38, in Republika district, Sliven.
The premises of the building are entirely used for residental purposes. The builing was constructed in 1962, according to the monolithic construction system. It is a 2-section massive building with basement (underground floor), 4 residential floors with load-bearing brick walls, pillars, girders, beams and inter-floor reinforced concrete floor constructions and a usable attic floor. It consists of 3 residential entrances - A(4 floors), B(4 floors), C(4 floors). Total number of apartments - 48. The roof is constructed with reinforced concrete and covered with voalite, and its drainage is external with gutters and downpipes. The slope of the roof surface is 2%. In the attic space there are usable attic rooms and terraces. There are storage rooms in the basement. Each entrance has a separate stairwell, there is no elevator. The access to the apartments is via double-arm ladder, which serves to access both the basement and the attic space. The building doesn't have a central heating system, and there is no local one. Most of the apartments are heated with electricity and some with solid fuel.
The current state of the building is energy consumption class D. The proposed energy-saving measures are the following:
1. Replacement of windows and doors
2. Thermal insulation of external walls
3. Thermal insulation of roof
4. Thermal insulation of floor
5. Replacement of lighting in the common areas
After the implementation of the project activities the building will aquire energy consumption class B, as well as reduction of the required energy costs by 694 572 kWh per year with an ecological equivalent of 101.36 t of CO2 emissions saved. The persantage of energy saving in the annual consumption of primary non-renewable energy is 58.79.
