How to get compliant and accessible data for the energy rating calculation of a building
The Energy Performance Certificate (EPC) of a building will only be able to serve its purpose if it is considered trustworthy while minimising the risk of non‐compliance of the actual building with the minimum energy performance requirements of the regulations. In doing so, two are the key parameters to be fulfilled:
- the input data for the energy performance calculation are compliant, i.e. the data have been obtained in accordance with the definitions and procedures of the applicable legislation, and there is an evidence of this compliance;
- the input data for the energy performance calculation are easily accessible, i.e. can be found, seen and used by the relevant experts by taking reasonable time, effort or money.
This QUALICHeCK report presents interesting approaches from different EU countries that could contribute to possible solutions towards compliant and/or easily accessible input data for building energy performance certificates. The approaches include among others:
- on line databases of product characteristics;
- procedures for generating reliable data for innovative products;
- qualification schemes for certain professions;
- sets of pre‐calculated values for certain technologies/aspects;
- rules for a consistent announcement of product performances;
whereby the proof that the data is compliant may come e.g. via one or a combination of the following ways:
- third party control
- declaration by the product supplier
- proven competence of experts in charge.
