Why Choose BS EN 17423:2020?

As the world moves towards more sustainable practices, the construction industry plays a pivotal role in reducing energy consumption and greenhouse gas emissions. The BS EN 17423:2020 standard provides a structured approach to calculating and reporting energy performance metrics, which are critical for achieving energy efficiency targets and complying with regulatory requirements.

Primary Energy Factors (PEF)

Primary Energy Factors are essential for understanding the total energy input required to deliver a unit of energy to the end-user. This standard outlines the methodology for calculating PEFs, enabling stakeholders to make informed decisions about energy sources and consumption patterns.

CO2 Emission Coefficient

The CO2 emission coefficient is a vital metric for assessing the environmental impact of energy use in buildings. By providing a clear framework for determining this coefficient, the standard helps professionals quantify and reduce the carbon emissions associated with building operations.

BS EN 17423:2020

This standard BS EN 17423:2020 Energy performance of buildings. Determination and reporting of Primary Energy Factors (PEF) and CO2 emission coefficient. General Principles, Module M1-7 is classified in these ICS categories:

• 13.040.01 Air quality in general
• 91.120.10 Thermal insulation of buildings

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.

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.
