Overview

EN ISO 52003-1:2017 - Energy performance of buildings - Part 1: General aspects and application to the overall energy performance - provides a framework for interpreting and using outputs from the EPB (energy performance of buildings) assessment standards. Published by CEN and aligned with ISO 52003-1:2017, this standard explains how to convert EPB indicators into requirements, ratings and energy performance certificates for regulatory and voluntary schemes while preserving national/regional flexibility.

Key topics and requirements

• Relation between EPB features, indicators, requirements and ratings: clarifies how overall EPB indicators (and their normalization to building size) relate to statutory requirements and rating procedures.
• Tailoring and project-specific values: discusses the use of tailored (project-specific) reference values for requirements or ratings depending on building characteristics.
• Reporting templates and standardized tables: provides standardized, non-restrictive tables for transparent reporting of choices related to overall EPB requirements (note: partial EPB tables are covered in other documents).
• EPB labels and certificate content: contains example label models and guidance on the information and graphical presentation of energy performance certificates.
• Certification scheme steps: lists procedural steps and content needed to establish an EPB certification scheme including quality control and compliance checks.
• Input and output data management: templates (Annex A normative; Annex B informative) for input/method selection and default choices to support consistent post-processing of EPB outputs.
• Quality control and compliance checks: guidance for ensuring reliable use of indicators in regulatory and certification contexts.

Practical applications

• Use EN ISO 52003-1:2017 to:
  • Convert building simulation or measured outputs into legally meaningful EPB requirements and ratings.
  • Design or harmonize national/regional energy performance certificate schemes and labels.
  • Define reporting and documentation rules for building energy assessments.
  • Support policymakers in aligning EPB indicators with the EU EPBD (2010/31/EU) and national transposition.

Who should use this standard

• Public regulators and authorities setting building energy policy
• Certification bodies and scheme operators
• Energy assessors, building energy modelers and auditors
• Architects, engineers and building owners seeking compliance or certification
• Researchers and consultants developing EPB rating scales or labels
