Full title and description

STB DIN EN ISO 15927-4 E 2001-02 — Hygrothermal performance of buildings — Calculation and presentation of climatic data — Part 4: Hourly data for assessing the annual energy use for heating and cooling. This publication is a national/adopted version designation (DIN/EN/ISO) with the E 2001-02 edition identifier; it defines a procedure to construct a representative reference year of hourly meteorological data (a Test Reference Year / Typical Meteorological Year) for use in building energy and hygrothermal assessments.

Abstract

This part of ISO 15927 specifies a statistical procedure for selecting 12 representative months and assembling them into a synthetic year of hourly meteorological data suitable for estimating average annual heating and cooling energy needs of buildings. The method is intended to produce a representative “reference year” for energy simulations and related hygrothermal assessments but is not designed to create extreme or design-years for rare-event analysis.

Scope

The standard establishes a stepwise procedure to create a representative hourly reference year by selecting the most typical month for each calendar month from a long-term measured record and concatenating those months. The produced reference year is intended for use in annual energy and hygrothermal performance assessments of buildings, building services and HVAC systems — not for extreme-event or design-load analyses. The procedure requires multi-year hourly meteorological datasets and includes quality checks and selection criteria for temperature, humidity, solar radiation and wind parameters.

Key topics and requirements

• Procedure for selecting representative months from long-term hourly meteorological records to build a Test/Typical Reference Year (TRY/TRJ).
• Parameters considered: dry-bulb temperature, relative humidity (or dew point), global/solar radiation, and wind speed/direction as required for energy simulations.
• Quality-check and data-completeness requirements for input time series (recommendation to use at least ~10 years of data where possible).
• Instructions for assembling hourly data into a continuous synthetic year suitable for annual energy calculations for heating and cooling.
• Limitations: not intended for constructing extreme or semi‑extreme years for rare-event or worst-case moisture/energy scenarios.
• Output intent: a standardized hourly dataset (TRJ/TMY) that reduces computational effort and permits consistent energy-simulation comparisons.

Typical use and users

Primary users are building simulation engineers, HVAC designers, energy modelers, façade and envelope consultants, researchers in building climatology, and national/regional bodies creating climatic reference datasets. Typical uses include generation of input weather files for annual energy simulations, comparative assessments of building designs, and preparing representative climate data for product and system testing. The method is also used by meteorological data providers to create TMY/TRJ datasets for engineering applications.

Related standards

ISO 15927 is a multipart series on hygrothermal performance and climatic data presentation. Related parts include ISO 15927-1 (monthly means), ISO 15927-2 (data for design cooling loads), ISO 15927-3 (driving rain index), ISO 15927-5 (design heat load data) and ISO 15927-6 (degree-days). National and regional procedures for typical meteorological years (TMY) and other reference-year methods are often developed alongside or using ISO 15927-4 as a reference.

A: It is a national/adopted edition (STB DIN EN ISO 15927-4 E 2001-02) of the ISO 15927-4 specification describing how to construct an hourly reference year for annual heating and cooling energy assessments. The international standard most commonly associated with this part is ISO 15927-4:2005.

Q: What does it cover?

A: It covers the statistical selection and assembly of representative months from long-term hourly meteorological records into a continuous synthetic year suitable for annual energy simulations; it sets out required input parameters, selection criteria and limitations of use (not for extreme-year analysis).
