Energy efficiency measures that are not included in the catalogue of standardized measures are referred to as “singular measures.” Due to their specific characteristics and technical particularities, these measures cannot be incorporated into a catalogue sheet.

Despite not being standardized, singular measures may entitle the applicant to the issuance of valid Energy Savings Certificates (CAEs), provided that certain requirements are met:
- They must have been implemented: CAEs may not be requested for singular measures that are still in the project or planning phase.
- The annual energy savings obtained must be verified by an accredited energy savings verifier: An ENAC-accredited verifier must confirm that the measure has been executed in accordance with Chapter V of Order TED/815/2023, of 18 July, and that the calculations, measurements, or energy audits are correct.
Justification of Singular Measures
In order to justify the implementation of a singular measure and request the issuance of CAEs, a specific procedure must be followed:
- Optional prior consultation: If the forecasted final energy savings exceed 1 GWh, a project description of the measure may be submitted to the National Coordinator, accompanied by a favorable prior assessment from an accredited energy savings verifier. This consultation is not mandatory but may provide the applicant with certainty as to the eligibility of the measure for obtaining CAEs.
- Documentation for the issuance request: Once the singular measure has been executed, an application must be filed with the Regional Manager, including the information and documentation required under Article 14 of Order TED/815/2023. In addition, the following specific documentation must be attached for singular measures:
- Descriptive report of the measure.
- Description of the methodology used to calculate the final energy savings.
- Energy audit report conducted prior to the implementation of the measure.
- Energy audit report conducted after the implementation of the measure.
- Where applicable, the energy performance certificate of the building or facility.
Calculation of Energy Savings
The calculation of final energy savings for singular measures shall be carried out in accordance with the principles set forth in Directive 2012/27/EU and Commission Recommendation (EU) 2019/1658. Furthermore, the specific methodology approved by Resolution of the Directorate-General for Energy Policy and Mines must be taken into account.
Basic principles for calculation:
- Additional savings: Final energy savings must be additional to any other savings obtained under other applicable legislation.
- Baseline: An energy consumption baseline prior to implementation of the measure must be established, and the savings shall be calculated as the difference between post-implementation actual consumption and the baseline.
- Normal operating conditions: Energy savings must be calculated under normal operating conditions.
- Rebound effect: Any rebound effect (i.e., an increase in energy consumption resulting from improved efficiency) must be duly considered.
- Prohibition of double counting: The same energy savings may not be accounted for different purposes.
In summary, singular energy efficiency measures, although not included in the catalogue of standardized measures, may be certified through CAEs provided that they meet the requirements of implementation, verification, and calculation of energy savings as established under the applicable regulations.
