An energy certificate is available for the property offered. In addition you receive low past consumption figures and the prospect of additional living space later. These are various pieces of information for your purchase. You must determine which condition is actually described and how it fits with the living you intend.
Start with the complete referenced object
Our editorial recommendation: Request the complete certificate version including recognisable calculation bases and recommendations. Reconcile location, building assignment, issue date and stated areas with the acquisition documents. A single photographed key figure does not answer which building parts were considered.
The official information describes the energy certificate as information on overall energy efficiency and points to the regional legal implementation. It names, among other things, building and reference data. [AUSWEISINHALT] This article concerns Austria. The version and regional basis applicable to your certificate will be clarified on the specific document.
Read key figure and definition together
Transfer a number important for the purchase only with its full designation, unit and recognisable reference. Have it explained which area, which climate reference and which calculated condition lie behind it. A value is not comparable merely because another offer also contains an energy figure.
The official explanation describes the heating demand (Heizwärmebedarf) as the calculated amount of heat required for space heating. It also emphasises that the certificate does not guarantee a specific personal energy consumption. [AUSWEISINHALT] A private calculation from a key figure, an arbitrary living area and an assumed price is therefore not used as a confirmed heating cost forecast.
Link the certificate to the building as it is today
Collect information and evidence on heating, the building envelope and works carried out after issue. Planned measures and actually completed works remain distinguishable. A more recent equipment offer is not a building key figure newly determined by you.
Present recognisable differences to a suitable specialist. What does the existing certificate describe, which information about the current condition is missing and which in-depth inspection is necessary for your decision? The article does not provide a remote diagnosis of the heating and does not derive a specific remaining useful life from a single key figure.
Treat past consumptions as a separate data series
Have it explained which periods, users and measured areas underlie the submitted consumption documents. Is it a complete year, were rooms unused and which energy positions are included? A low payment amount can also answer a different question than a documented energy quantity.
Note your planned use alongside. Describe additional rooms and foreseeable changes explicitly. This information is incorporated into an appropriate technical cost estimate. It is not converted into an apparently accurate forecast by a self-chosen flat safety margin.
Hypothetical case: Unused rooms are to be used daily in future
A family wants to buy a house and regularly occupy an area that has been hardly used until now. They receive past bills and initially adopt their amount unchanged as their own annual requirement. At the same time it is still unclear how the additional area was recorded in the existing certificate.
The family first has the object assignment and intended use explained. Afterwards past consumption basis, current condition and their personal demand are assessed together. The example process does not predict a specific cost increase. It shows that a favourable past bill can have a different usage context than the planned own dwelling.
Also obtain the legal significance of the key figures
§6 EAVG regulates, when presented before submission of the declaration of contract, the energy key figures as a warranted characteristic taking into account the legally named unavoidable ranges. It also deals with the direct liability of the preparer for the correctness of the certificate. [RECHTSBEZUG] The boundary to a personal consumption forecast therefore does not mean that the document is legally meaningless.
Have contradictory or purchase‑decisive information checked before commitment and treated appropriately in contract advice. This article does not establish any concrete inaccuracy or any claim. The separate article on handover goes into greater detail on obtaining the document; here its full scope of statements is integrated into the acquisition decision.
Your final status combines the clarified certificate, the building condition today, past data and your own housing plan. Remaining technical or economic points remain visible as such.
