Buyers can only meaningfully classify energy information if the origin and time period are clear. Therefore, collect evidence of heating, consumption and work carried out before you make blanket promises of efficiency.
What owners can gather
Write down the heating system, installation and maintenance data, existing consumption bills and documented work on windows, roof and building envelope. A single year of consumption says little about the building alone: usage and weather influence numbers. Unknown values remain marked as open.
What the GEAK does
The cantons' building energy certificate describes the energy quality according to a uniform system. A GEAK Plus supplements this with a consulting report with variants. Loud official GEAK FAQ Only certified GEAK experts are allowed to issue a GEAK. IMLU does not issue such an ID card.
Whether there is an obligation or a subsidy requirement for your property must be clarified on a cantonal and property-specific basis. It is not possible to derive a uniform rule for all six IMLU cantons from a general website.
In the sales dossier
Separate measured or documented data from a planned renovation. An existing GEAK can be attached; a measure that has not yet been carried out can be described as intentional. If anything is unclear, a technical examination is the right next step. To decide on work.
