Full title and description

Energy performance of buildings — Overarching EPB assessment — Part 1: General framework and procedures. This International Standard establishes a systematic, modular framework and common procedures for assessing the overall energy performance of new and existing buildings using calculation and/or measurement, enabling assessment in terms of primary energy and other energy-related metrics.

Abstract

ISO 52000-1:2017 provides a comprehensive, modular structure to produce consistent overall and partial energy performance (EPB) indicators for buildings. It defines assessment routes (calculation and measurement), normalization and reporting rules, and the interfaces to other EPB standards so that building energy performance can be evaluated for design, “as built” verification, in‑use operation and renovation contexts.

Scope

ISO 52000-1:2017 defines the overarching framework and procedures required to assess overall energy performance of buildings. It is applicable to both calculated and measured approaches, supports results expressed in primary energy or alternative energy-related metrics, and covers multiple applications including design-stage assessment, “as-built” verification and in-use performance and renovation. The standard also defines how individual EPB modules and related standards interconnect within a modular assessment structure.

Key topics and requirements

• Modular, overarching EPB assessment framework that integrates multiple EPB standards and modules (interfaces to more detailed calculation and measurement standards).
• Procedures for both measured energy performance (metering) and calculated performance (modelling), and guidance for comparing the two.
• Definition of output indicators, normalization rules (e.g., reference floor area), categorization by building and space types, and reporting formats.
• Provision for reporting and documenting choices needed to complete an EPB assessment (e.g., primary energy factors and CO2 coefficients — see companion parts for detailed procedures).
• Support for use in regulation, certification, design optimisation and in‑use verification of building energy performance.

Typical use and users

Used by building energy assessors, architects, mechanical/electrical engineers, energy modelers, certification bodies, regulators and policymakers. Typical uses include producing comparable overall energy performance indicators, supporting building energy certification schemes, regulatory compliance checks, design optimisation, and harmonizing national/regional assessment methods with an international framework.

Related standards

ISO 52000-1 is the lead document of the ISO 52000 series and is connected with several companion parts and technical reports, for example ISO 52003-1 (indicators, requirements, ratings and certificates), ISO/TR 52003-2 (explanatory report), ISO 52000-3 (primary energy factors and CO2 reporting principles), and the ISO 52016 series (calculation procedures for heating and cooling energy needs). These related documents provide detailed procedures, reporting tables and supplementary calculation rules that complete the modular EPB assessment chain defined in ISO 52000-1.

FAQ

Q: What is this standard?

A: ISO 52000-1:2017 is an international standard that provides the general framework and procedures for assessing the overall energy performance of buildings in a consistent, modular way, supporting both calculated and measured approaches.

Q: What does it cover?

A: It covers the structure, procedures and output definitions for EPB assessments — including normalization and reporting rules — and how to interface with more detailed calculation and measurement standards to deliver overall building energy performance indicators (e.g., primary energy consumption).

Q: Who typically uses it?

A: Practitioners such as energy assessors, engineers, architects, certification bodies, regulators and policymakers who need a harmonized method to evaluate, compare and report building energy performance.

Q: Is it current or superseded?

A: ISO 52000-1:2017 was published in June 2017 (Edition 1). The ISO bibliographic record shows it was reviewed and confirmed during the ISO review cycle and remains the current edition; companion parts in the ISO 52000/52016 families have been published subsequently to provide complementary procedures (e.g., parts addressing primary energy factors and updated calculation procedures published in 2023).

Q: Is it part of a series?

A: Yes — it is the lead/overarching document of the ISO 52000 series of EPB standards and links to multiple related standards (for indicators, calculation methods, primary energy factors and explanatory reports) that together form a modular EPB assessment system.

Q: What are the key keywords?

A: Energy performance of buildings, EPB, primary energy, energy indicators, modular assessment, measurement and calculation, reporting, certification.
