prEN 17423


This document provides a transparent framework for reporting on the choices related to the procedure to determine PEFs and CO2 Emission coefficients for energy delivered to and/or exported by the buildings as described in EN ISO 52000-1:2017. Exported PEFs and CO2 Emission coefficients can be different from those chosen for delivered energy.

This document can be considered as a supporting/complementing standard to EN ISO 52000-1, as the latter requires values for the PEFs and GHG Emissions factors to complete the EPB calculation.

Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1.
