Buildings with EPCs registered
While it is not compulsory under the EPBD to set up a central/regional EPC register, almost all Member States have moved further than the obligations and set up a system to collect EPC data voluntarily. In 11 out of 28 Member States, in order to issue an EPC, this must be uploaded to the central database to be officially approved (BPIE, 2014).
These EPC registers are the primary source of information regarding certified buildings. The share of buildings registers in the EPC database varies across Europe.
Denmark, the Netherlands and Ireland are the only countries where the share of the dwellings with Energy Performance Certificates exceeds 15%.
