Full title and description

Energy performance of buildings - External climatic conditions — Part 2: Explanation and justification of ISO 52010-1. This ISO technical report (ISO/TR 52010-2:2017) provides explanatory material and justification to support correct understanding and practical application of the methods given in ISO 52010‑1; it contains only guidance and no normative requirements.

Abstract

ISO/TR 52010-2:2017 contains information to support the correct understanding and use of ISO 52010‑1 (Conversion of climatic data for energy calculations). The report is non‑normative and intended to clarify concepts, provide examples and background rationale for the procedures specified in Part 1.

Scope

ISO/TR 52010-2:2017 provides explanatory guidance and justification for the calculation procedures and data‑handling conventions given in ISO 52010‑1. It is intended to help users interpret and correctly apply Part 1 in building energy calculations; it does not introduce normative requirements and should be used as supporting background material alongside ISO 52010‑1.

Key topics and requirements

• Explanation and justification of the methods presented in ISO 52010‑1 (conversion and processing of climatic data for energy calculations).
• Clarification of assumptions, parameter definitions and practical implications for modelling solar irradiance and related climatic inputs.
• Worked examples and illustrative information to support consistent application of Part 1 procedures.
• Guidance on the relationship between climatic inputs for thermal performance, daylighting and system component calculations (references to complementary standards where relevant).
• Non‑normative advice to help software developers, analysts and standards bodies interpret Part 1 correctly in national/regional implementations.

Typical use and users

Used by building energy modelers, simulation software developers, consultants, researchers, national standards bodies and authorities responsible for energy performance regulations. Typical uses include interpreting ISO 52010‑1 procedures, validating climatic input preparation in simulation tools, and harmonizing national datasets with ISO guidance.

Related standards

Directly linked to ISO 52010‑1:2017 (Energy performance of buildings — External climatic conditions — Part 1: Conversion of climatic data for energy calculations). It also complements other standards on climatic data and building performance (for example standards addressing long‑term meteorological data and moisture/wind procedures such as ISO 15927‑4 and regional EPB-related guidance).

FAQ

Q: What is this standard?

A: ISO/TR 52010-2:2017 is a technical report that provides explanatory material and justification to support correct understanding and use of ISO 52010‑1 (conversion of climatic data for energy calculations). It is guidance only and contains no normative clauses.

Q: What does it cover?

A: It covers explanations, background rationale, illustrative examples and clarifications of the procedures given in ISO 52010‑1 — primarily the conversion and handling of climatic inputs (solar irradiance, illuminance and related parameters) used in building energy and daylighting calculations.

Q: Who typically uses it?

A: Building energy analysts, simulation software developers, consultants, researchers and standards or regulatory bodies that implement or interpret ISO 52010‑1 for national/regional energy performance assessments.

Q: Is it current or superseded?

A: ISO/TR 52010‑2 was published in 2017 and is listed as published by ISO. There is no public indication on the ISO catalogue that it has been withdrawn or superseded; users should check the ISO catalogue or their national standards body for any later review or confirmation actions.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 52010 series. Part 1 (ISO 52010‑1:2017) provides the normative calculation procedures for conversion of climatic data; Part 2 supplies the explanatory and justificatory background for those procedures.

Q: What are the key keywords?

A: Climatic data conversion, solar irradiance, illuminance, building energy performance, external climatic conditions, ISO 52010, guidance, technical report.
