Division 3.12 Guidance on the development of more accurate methodologies

It is envisaged and encouraged that Member States do their own estimations for both SPF and H_HP. If improved estimations can be made, such national/regional approaches should be based on accurate assumptions, representative samples of sufficient size, resulting in a significantly improved estimate of renewable energy from heat pumps compared to the estimate obtained through the use of the method set out in this Decision. Such improved methodologies may be based on detailed calculation based on technical data taking into account, among other factors, year of installation, quality of installation, compressor type, operation mode, heat distribution system, bivalence point and the regional climate.

If measurements are only available at other system boundaries than the system boundary set out in Section 3.4, appropriate adjustments should be made.

Only those heat pumps with energy efficiency above the minimum threshold, as set out in Annex VII to the Directive, shall be included for the calculation of renewable energy for the purpose of the Directive.

Member States are invited, when alternative methodologies and/or values are used, to submit them to the Commission together with a report describing the method and data used. The Commission will, if necessary, translate the documents and publish them on its transparency platform.
