Depending on the needs and budget, the energetic renovation begins with partial measures such as improving the thermal insulation on the roof and walls, including replacing windows, up to the passive house in the existing building.
According to a study by KfW, building renovation can save energy as follows:
– Fassadendämmung: 21%
– Sanierung Heizanlage: 21%
– Dachdämmung: 14%
– Dämmung Kellerdecke: 9%
– Fenster erneuern: 5%
When considering the economics of an energetic refurbishment, you should, on the one hand, consider the considerable state subsidies, as well as the future energy savings. We would be happy to advise you and work with you to develop a tailor-made renovation concept.
