Full title and description

St ISO 52010-1-2017 — Energy performance of buildings — External climatic conditions — Part 1: Conversion of climatic data for energy calculations. This International Standard defines standard procedures to convert measured or synthesized climatic data (especially solar irradiance) into the formats and components needed as input for building energy, thermal, solar and daylighting calculations.

Abstract

ISO 52010-1:2017 specifies calculation procedures for converting climatic data for energy calculations. The principal element is a method to compute solar irradiance on surfaces with arbitrary orientation and tilt; a simple procedure for converting solar irradiance to illuminance is also provided. The standard supplies a consistent set of converted climatic inputs for Energy Performance of Buildings (EPB) assessment modules and indicates how other climatic parameters (wind, temperature, humidity, long-wave radiation) are to be obtained or passed through from established meteorological procedures.

Scope

ISO 52010-1:2017 provides standardised procedures to convert hourly climatic data to the forms required by energy-performance calculations for buildings and building components. It covers calculation of solar irradiance on inclined and oriented surfaces, basic conversion from irradiance to illuminance for daylighting assessments, geometric/shading procedures, and metadata/reporting templates for climatic time series. Other meteorological parameters required by EPB standards are referenced to established ISO/WMO procedures and passed through or documented as input without conversion where appropriate.

Key topics and requirements

• Method for calculating solar irradiance on a surface with arbitrary orientation and tilt (direct, diffuse and ground-reflected components).
• Simple conversion method from solar irradiance to daylight illuminance for use in lighting and daylighting calculations.
• Procedures to account for external shading geometry, object heights and distances, and surface reflectivity.
• Required climatic input data, time-step conventions (hourly basis), and aggregation rules for daily/monthly/yearly values.
• Templates and reporting requirements for documenting the origin, processing and intended use of climatic time series.
• Interoperability and intended role as the single climatic-data conversion source within the ISO EPB (Energy Performance of Buildings) suite.

Typical use and users

Primary users include building energy modelers, daylighting and HVAC designers, simulation software developers, national authorities and conformity assessment bodies, researchers and consultants involved in energy performance assessments, building component testing (PV, solar thermal, glazing) and the preparation of reference climatic datasets for regulation or certification. Typical use cases: preparing weather input files for simulation tools, calculating incident solar gains on façades and roofs, estimating illuminance from irradiance for simple daylight checks, and documenting climatic-data provenance for EPB assessments.

FAQ

Q: What is this standard?

A: ISO 52010-1:2017 is an International Standard that specifies methods to convert climatic/weather data — primarily solar irradiance — into the formats and components needed for building energy, thermal and daylighting calculations.

Q: What does it cover?

A: It covers calculation of solar irradiance on surfaces of arbitrary tilt and orientation (direct/diffuse/ground-reflected components), a simple irradiance-to-illuminance conversion, shading geometry procedures, required input data and hourly time-step conventions, and reporting templates for climatic time series used in EPB calculations.

Q: Who typically uses it?

A: Building energy modelers, daylighting designers, simulation software implementers, national regulators and assessors, researchers, and consultants preparing or validating weather inputs for building performance simulations and component energy assessments.

Q: Is it current or superseded?

A: ISO 52010-1 was published in June 2017 (Edition 1) and was reviewed and confirmed as current in 2022. There is no indication of a superseding version as of March 1, 2026, so the 2017 edition remains the valid edition.

Q: Is it part of a series?

A: Yes. ISO 52010-1 forms part of the Energy Performance of Buildings (EPB) set of standards (ISO 52000 series). It is complemented by ISO/TR 52010-2 (explanatory technical report) and related EPB standards such as ISO 52000-1, ISO 52016-1, ISO 52018-1 and others.

Q: What are the key keywords?

A: Climatic data conversion, solar irradiance, illuminance conversion, inclined surface, EPB, weather file, hourly data, shading, ISO 52010.
