The Public Housing Fund of the Municipality of Koper intends to carry out energy rehabilitation of the Cesta na Markovec 1c building in Koper. Energy refurbishment will include additional thermal insulation of the entire envelope of the building, replacement of all joinery including replacement of exterior and interior window sills to increase the thickness of the facade layer and thermal insulation of the roof panel against the attic. A new entrance door will be installed in the stairwell towards the basement floor. To improve the efficiency of the heating system, the system will be hydraulically balanced, reducing the working power of the boiler plant and reducing the temperature of the heating water.
