Information from energy performance certificates and about the national building stock
Article 5
1. For each calendar year referred to in Article 4(1), Member States shall transfer to the EU Building Stock Observatory the following information in relation to energy performance certificates: (a) share of buildings in the national total building stock covered by valid energy performance certificates; (b) number of energy performance certificates issued; (c) total floor area of buildings for which energy performance certificates have been issued [m 2 ]; (d) average annual primary energy use calculated from the issued energy performance certificates[kWh/(m 2 .yr)]; (e) cumulative primary energy consumption calculated from the issued energy performance certificates [MWh/yr]; (f) average annual final energy use calculated from the issued energy performance certificates [kWh/(m 2 .yr)]; (g) cumulative final energy consumption calculated from the issued energy performance certificates [MWh/yr]; (h) average energy needs calculated from the issued energy performance certificates [kWh/(m 2 .yr)]; (i) cumulative on-site renewable energy production calculated from the issued energy performance certificates [MWh/yr]; (j) cumulative operational greenhouse gas (GHG) emissions calculated from the issued energy performance certificates [tCO 2 eq/yr]; (k) average operational GHG emissions from the issued energy performance certificates [kgCO 2 eq/(m 2 .yr)]; (l) average life-cycle global-warming potential (GWP), where available, from the issued energy performance certificates [kgCO 2 eq/m 2 ]; (m) number of buildings with the capacity to react to external signals, per energy class, from the issued energy performance certificates; (n) number of buildings with a heat distribution system inside the building capable of working at low or more efficient temperature levels, from the issued energy performance certificates. 2. Member States shall transfer to the EU Building Stock Observatory the aggregated and anonymised public information on the total number of buildings or building units or total floor area in the national building stock. 3. Member States shall provide a general explanation of the national energy performance certificate schemes, using the format set out in Annex I of this Regulation. That explanation shall be provided when the first transfer of information is made to the EU Building Stock Observatory and at every time thereafter when the explanation needs to be updated following changes in the national energy performance certificate schemes.
