How much can I save in heating over different time periods?
The lower the original level, the higher the savings. Energy prices will raise significantly faster than other prices in the future, which means that all repairs will have better payback. The profitability of an improvement investment must be calculated case by case. Heating costs can easily be halved by improving the insulation of the building’s shell and efficiently recovering the heat from exhaust air. Mr Sakari Pulakka, Special Researcher, VTT, has calculated that the savings will amount to 30,000–50,000 euro in 25 years. In addition, he estimated that the resale value of such a house will be 10–30 per cent higher than normal houses.
