ÖNORM H 5056-1

Issue date: 2025 10 15

Energy performance of buildings – Heating energy demand – Part 1: Principles and determination

This document defines the principles for calculating the heating energy demand based on user profiles for the heat requirement for hot water and room heating. Calculation is done by evaluating the loss of heat emission, heat distribution, heat storage and heat provision. The yields from solar thermal and photovoltaic systems are also determined, both for hot water and for room heating. These calculations are based on monthly balancing. The determined results are used to create the energy certificate in accordance with OIB Guideline 6.

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
