Savings are approximate and no guarantee can be given for the correctness of the results.
The savings depend on your heating habits and the structural fabric of the existing building.
The U-value was calculated from the year of construction of the building and can vary widely.
The calculation assumes a solid construction and heating with night setback.
The savings will be lower with lightweight construction and without night setback.
By increasing the surface temperatures, the room temperature was reduced without this adversely affecting comfort.
We have assumed a central apartment in the apartment block (i.e. not a ground floor or top-floor apartment). With apartment blocks, it should be borne in mind that the heating costs are split according to individual usage and standing charges. The actual savings depend on the allocation formula.
The efficiency class stated was calculated based on consumption. These details are intended for information purposes only and do not replace an energy certificate. A Demand Certificate must be calculated individually for each building and can present seriously differing results.
