Energy performance of buildings - Basic principles for the set of EPB standards

This document describes the basic principles to be followed in the development and maintenance of standards intended to support the assessment of the overall energy performance of a building (EPB) using a holistic approach.
This document supports the development and maintenance of a set of EPB standards that provides a systematic, clear, consistent and comprehensive methodology for the benefit of professionals and government entities. The main application is the assessment of the overall energy performance of a building in the context of building regulations, e.g. to specify EP requirements, EP rating and EP certificates.
The principles cover general and common aspects on the required quality, accuracy, usability, consistency and interoperability of the EPB standards as a set and individually. For that purpose, this document provides guidance on the process, structure and layout of these EPB standards and accompanying publications, complementary to the CEN and ISO internal regulations.
This document forms the basis for detailed technical rules given in CEN/TS 16629, in the overarching EPB standard, EN ISO 52000-1:2017, and in supporting documents.

Energieeffizienz von Gebäuden - Grundlagen für das EPB-Normenpaket

Performance énergétique des bâtiments - Principes fondamentaux pour la série de normes sur la performance énergétique des bâtiments

Le présent document décrit les principes fondamentaux à suivre dans l’élaboration et le maintien à jour des normes destinées à venir à l’appui de l’évaluation de la performance énergétique globale d’un bâtiment (PEB) en utilisant une approche holistique.
Le présent document vient à l’appui de l’élaboration et du maintien à jour d’un ensemble de normes PEB qui fournit une méthodologie systématique, claire, cohérente et complète au profit des professionnels et des organismes publics. La principale application est l’évaluation de la performance énergétique globale d’un bâtiment dans le contexte des réglementations de construction, par exemple pour spécifier les exigences de PE, l’évaluation de la performance énergétique et les certificats de type DPE.
Les principes couvrent les aspects généraux et communs relatifs à la qualité requise, la précision, la facilité d’utilisation, la cohérence et l’interopérabilité des normes PEB en tant qu’ensemble et individuellement. À cette fin, le présent document fournit des recommandations relatives au processus, à la structure et à la présentation de ces normes PEB et des publications d’accompagnement, en complément des règlements intérieurs du CEN et de l’ISO.
Le présent document constitue le socle des règles techniques détaillées fournies dans la CEN/TS 16629, dans la norme-cadre PEB, l’EN ISO 52000 1:2017 et dans les documents complémentaires.

This Technical Specification (CEN/TS) was approved by CEN on 14 July 2024 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
United Kingdom.
