Energy renovations are worth carrying out because they benefit homeowners. The energy efficiency of nearly all blocks of flats in Helsinki can be improved in a financially viable manner.
In blocks of flats, energy renovations can potentially cut heating costs by as much as half. This translates to a significant decrease in the maintenance charge and living expenses as well as savings over time, as heating is the single largest expense item of housing companies. Energy renovations also have a positive impact on the value of dwellings.
Some energy renovations also improve comfort of living. Improving the thermal insulation of windows and walls and making ventilation more efficient means that you no longer have to endure excessively hot or cold indoor temperatures or draughts at home.
