Hello JanBana,
even though the post is already older, an energy certificate or the calculated heating costs should not be the decisive factor in buying a house. As €uro rightly said, the values of an energy certificate serve merely as a guideline. Furthermore, it must be clarified whether the values come from a demand certificate or a consumption certificate. A demand certificate represents a kind of "standardized" energy demand, whereas the consumption certificate almost exclusively reflects user behavior. Therefore, the roughly determined consumption based on the energy certificate can differ significantly from the actual consumption.
The house is relatively new, but unfortunately several amendments to the Energy Saving Ordinance have come into effect in the meantime, so that the building physics of the property has already somewhat diverged from the current technical standards. Nevertheless, I would not buy a house without expert advice. This includes reviewing the documents (plans, calculations, land register, building encumbrances, etc.) as well as an inspection, which can be conducted for a small fraction of the property purchase price. It is important to already consider investments in the coming years when buying. For example, heating systems are assumed to have a service life of around 20 years. Thus, in about 5 years a system replacement would be necessary and approximately €5,000 should be planned, more depending on the scope of further measures. This, in turn, will significantly reduce heating costs, regardless of user behavior.
Best regards, Erik
