Full title and description

ISO/TR 52003-2:2017 — Energy performance of buildings — Indicators, requirements, ratings and certificates — Part 2: Explanation and justification of ISO 52003-1. This Technical Report provides explanatory material to support correct understanding and use of ISO 52003-1; it is informational (non‑normative) and clarifies the rationale, relationships with other EPB standards and examples referenced in Part 1.

Abstract

ISO/TR 52003-2:2017 complements ISO 52003-1 by explaining the concepts, choices and structure used in the normative Part 1. It contains guidance, illustrative material and justification for indicator selection, rating approaches and certificate presentation but does not introduce normative requirements. The report also shows the relation between the ISO 52003 series and other energy performance of buildings (EPB) standards and product‑level standards (see Clause 6, Figure 4).

Scope

This Technical Report refers specifically to ISO 52003‑1 and provides explanation and justification for the indicators, requirements, ratings and certificate concepts introduced in Part 1. It is intended to help standards users interpret the terms, choices and examples in ISO 52003‑1 and to show how the document relates to other EPB and product standards. It contains no normative provisions; users should follow ISO 52003‑1 for requirements.

Key topics and requirements

• Explanatory guidance for the concepts and structure of ISO 52003‑1 (indicators, requirement definitions, rating scales and certificate content).
• Justification of methodological choices made in ISO 52003‑1 and illustrative examples to aid interpretation.
• Discussion of relationships between building‑level indicators and product standards relevant to EPB assessment.
• Non‑normative material to support national application and alignment with regional schemes (for example CEN adoptions).
• References to the normative ISO 52003‑1 text and to related EPB standards and technical guidance.

Typical use and users

Used by standards developers, national normalization bodies, building energy assessors, certification bodies, policy makers and researchers who need authoritative explanation of the ISO 52003‑1 approach to indicators, ratings and certificates. It is especially helpful when implementing or adapting ISO 52003‑1 in national/regional EPB frameworks or when aligning certification schemes and product declarations with building‑level ratings.

Related standards

Key related documents include ISO 52003‑1 (Part 1: General aspects and application to overall energy performance), the broader ISO 52000 series on energy performance of buildings (for calculation framework and indicators) and relevant EN/CEN adoptions or national implementations of ISO 52003 parts. Users should consult ISO 52003‑1 alongside this TR for normative requirements.

Q: What does it cover?

A: It covers explanatory text, illustrative examples and rationale for the indicators, requirement definitions, rating approaches and certificate presentation described in ISO 52003‑1. It shows relationships with other EPB and product standards but does not add requirements.

Q: Who typically uses it?

A: Standards developers, national bodies, building energy assessors, certification bodies, policy makers and researchers who implement, interpret or align building energy indicators, ratings and certificates.

Q: Is it current or superseded?

A: As published, ISO/TR 52003‑2:2017 is a valid Technical Report (Edition 1, 2017). Users should check the ISO catalogue or their national standards body for any amendments or newer editions after 2017 before relying on it for up‑to‑date requirements or implementations.

Q: Is it part of a series?

A: Yes — it is part of the ISO 52000/52003 family addressing energy performance of buildings; specifically it complements ISO 52003‑1 (the normative Part 1) and sits within the set of documents that define indicators, calculation frameworks and certification approaches for EPB.
