VDI 6016:2025-09 - Draft

Fluid dynamic calculations are used in various areas of building technology to analyse the properties and effects of air, gas or liquid flows. Among other things, they are used to increase energy efficiency, predict and optimise thermal and acoustic comfort as well as to test and dimension safety-relevant processes and facilities (e. g. dispersion of pollutants or aerosols, fire protection, explosion protection, hygiene). They also support the dimensioning of technical building components.This standard provides engineers and users of calculation results with guidance for the commissioning and application of CFD methods in building services engineering. It gives an overview of common calculation methods and provides information on the appropriate and reliable use of numerical flow simulations. The standard defines the requirements for carrying out computational fluid dynamics (CFD) simulations in order to improve the traceability and reliability of the results. At the same time, it takes into account the dynamic further development of programmes and methods without hindering positive innovations through specifications.
