Renovation of a multi-family housing building
A multi-family housing building was renovated by insulating its exterior walls and foundation, replacing windows and the roof, and modernizing the heating system (installing a gas boiler-house and solar collectors).
A three-storey block residential house originally built in 1958 was renovated in Panevezys town with a view to achieve a higher energy efficiency class and to reduce thermal energy costs. The project included the following works: patching of wall cracks, insulation of walls with thermal insulation plates in the thickness of 130 mm, finishing of walls, external insulation of the base and the foundation with thermal insulation plates in the thickness of 110 mm, replacement of old wooden windows and balcony doors in the flats with plastic window and door frames with insulated glazing units, insulation of the unheated attic floor, reconstruction of the heating system by installing a gas boiler-house and solar collectors, replacing radiators and installing individual heating meters.
Barriers and Drivers
The main factor for the housing owners' association was improvement of thermal efficiency of the building and reduction of energy costs
Renovation of the building resulted in lower maintenance costs
More comfortable living conditions in a higher value flat
After the renovation of the house, thermal energy consumption went down by 62,1%, energy efficiency class of the house changed from E to B
