Full title and description

ISO 52018-1:2017 — Energy performance of buildings — Indicators for partial EPB requirements related to thermal energy balance and fabric features — Part 1: Overview of options. This International Standard provides an overview of options for using partial energy performance of buildings (EPB) indicators as the basis for requirements and reporting related to building fabric and the building thermal balance (heating, cooling and indoor thermal excursions).

Abstract

ISO 52018-1:2017 describes how outputs from the EPB assessment standards can be used as partial indicators for regulatory, decision-making and information purposes. The document focuses on indicators related to the building fabric and to the thermal balance (heating need, cooling need and free-floating temperatures, including overheating and excessively cold conditions). It provides structured, standardised tables for reporting the choices made when setting partial EPB requirements while preserving flexibility for regulatory implementation.

Scope

This part of ISO 52018 addresses the use of partial EPB indicators as the basis for requirements or choices related to thermal energy balance and building fabric features. It covers indicators that can be used to express heating and cooling needs, the risk/occurrence of overheating or excessive cold (free-floating temperature indicators), and fabric-related performance attributes that affect these thermal outcomes. The standard supplies reporting tables and an overview of possible options so that regulators and other stakeholders can document and compare the choices made when defining partial EPB requirements.

Key topics and requirements

• Definition and categorisation of partial EPB indicators related to thermal balance and fabric features.
• Indicators addressing heating need and cooling need as partial performance metrics.
• Indicators addressing free‑floating indoor temperatures and overheating / underheating risks.
• Structured tables for reporting regulatory choices and options (to enhance transparency and comparability).
• Guidance for “post‑processing” of EPB assessment outputs to derive regulatory indicators.
• Emphasis on non‑restrictive options—standard supplies formats and choices without prescribing a single regulatory approach.

Typical use and users

ISO 52018-1 is used by national and regional regulators developing partial EPB requirements, by policy makers and public authorities assessing regulatory options, and by consultants, energy assessors, building designers and researchers who need to report or compare partial energy performance indicators. It is also a tool for stakeholders who prepare documentation to support regulatory impact assessments or who perform building stock analyses using standardised indicators.

Related standards

ISO 52018-1 sits within the ISO EPB (energy performance of buildings) family and is intended to be used alongside related documents such as ISO 52000-1 (EPB assessment — general framework), ISO/TR 52018-2 (Part 2: Explanation and justification of ISO 52018-1 — technical report), ISO 52010-1 (external climatic conditions), ISO 52016-1 (calculation of energy needs for heating and cooling), and standards addressing solar, daylight and component properties (e.g., ISO 52022‑1). Many national and regional adoptions (EN ISO / national identical publications) exist.

A: It covers the types of partial indicators that relate to heating and cooling needs and indoor temperature excursions (overheating or excessive cold), and supplies standardised reporting tables and options to document regulatory choices.

Q: Who typically uses it?

A: National and regional regulators, policy makers, energy consultants, building designers, assessors and researchers use it to design, document or compare partial EPB requirements and to post‑process EPB assessment outputs.
