Commission Implementing Regulation (EU) 2025/1328 of 30 June 2025 implementing Directive (EU) 2024/1275 of the European Parliament and of the Council by establishing common templates for the transfer of information from national energy performance of buildings databases to the EU Building Stock Observatory

Article 1

Subject matter

This Regulation sets out common templates for transferring information from the national databases for the energy performance of buildings to the EU Building Stock Observatory.

Article 2

Definitions

For the purposes of this Regulation, the following definitions shall apply:

(1) ‘mandatory (M)’ means a category of information that Member States are required to submit to the EU Building Stock Observatory;

(2) ‘mandatory if available (Miav)’ means a category of information that Member States are required to submit only if such information is available to them at the time of submitting the information;

(3) ‘mandatory if applicable (Miap)’ means a category of information that Member States are required to submit if it is required by Union or national legislation;

(4) ‘voluntary (V)’ means a category of information which Member States submit on a voluntary basis.

Article 4

Scope and level of aggregation of information to be transferred

Article 5

Information from energy performance certificates and about the national building stock

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 [m²];

(d) average annual primary energy use calculated from the issued energy performance certificates[kWh/(m².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/(m².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/(m².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 [tCO2eq/yr];

(k) average operational GHG emissions from the issued energy performance certificates [kgCO2eq/(m².yr)];

(l) average life-cycle global-warming potential (GWP), where available, from the issued energy performance certificates [kgCO2eq/m²];

(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.

Article 6

Information from reports on the inspection of heating, ventilation and air-conditioning systems

Article 7

Information from renovation passports

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 renovation passports:

(a) number of issued renovation passports;

(b) average current energy performance of the buildings, in primary energy [kWh/(m².yr)];

(c) estimated energy performance class of the buildings after completion of all renovation steps [kWh/(m².yr)];

(d) total estimated energy savings in primary or final (²) energy consumption after the completion of all renovation steps [MWh/yr];

(e) average estimated energy savings in primary or final (³) energy consumption after the completion of all renovation steps, in percentage improvement compared to the energy consumption before undertaking the renovation [%];

(f) total estimated operational GHG emission savings after the completion of all renovation steps [tCO2eq/yr];

(g) average estimated operational GHG emission savings after the completion of all renovation steps [kgCO2eq/yr];

(h) average estimated cost savings on energy bills after completion of all renovation steps [EUR/building or building unit/yr];

(i) average estimated investment to complete all renovation steps [thou. EUR/m²].

Article 8

Information from smart readiness indicator

For each calendar year referred to in Article 4(1), the following information regarding the smart readiness indicator shall be transferred to the Building Stock Observatory from the date of application of the Commission Delegated Act referred to in Article 15(2) of Directive (EU) 2024/1275 using the format set out in Annex I and the formulas set out in Annex II of this Regulation:

(a) number of buildings that received a smart readiness indicator;

(b) average smart readiness indicator score of the buildings referred to in point (a);

(c) average score for optimising energy efficiency and overall in-use performance of the buildings referred to in point (a);

(d) average score for adapting operation to the needs of the occupant of the buildings referred to in point (a);

(e) average score for adapting to signals from the grid of the buildings referred to in point (a).

Article 9

This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.

This Regulation shall be binding in its entirety and directly applicable in all Member States.
