scope:

This document provides a transparent framework for reporting on the choices related to the procedure to determine primary energy factors (PEFs) and CO₂ emission coefficients for energy delivered to and exported from the buildings as described in EN ISO 52000-1.

This document specifies the choices to be made to calculate the PEF(s) and CO₂ emission coefficients related to different energy carriers. PEFs and CO₂ emission coefficients for exported energy can be different from those chosen for delivered energy.

This document is primarily intended for supporting and complementing EN ISO 52000-1, as the latter requires values for the PEFs and CO₂ emission coefficients to complete the EPB calculation. But it can also be used for other applications.

NOTE The CO₂ emission coefficients allow calculating greenhouse gas emissions. According to the choices made, the CO₂ emission coefficients represent only CO₂ emissions or also other greenhouse gases.

Table 1 shows the position (marked by "X") of this document within the modular structure as set out in EN ISO 52000-1.

The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
