What is a WUFI Model?
WUFI (Wärme Und Feuchte Instationär, which translates to Transient Heat and Moisture) is a computer software program used for simulating and analysing heat and moisture transfer in building materials and assemblies.
It was developed by the Fraunhofer Institute for Building Physics in Germany and is widely used by building professionals, researchers, and manufacturers around the world.
Do I require a WUFI Model?
Whilst there is no current criteria, regarding moisture, that requires a WUFI Model within the Building Codes of Australia. However, this criteria is said to be tightening to ensure built developments have a higher degree of condensation and moisture management. A WUFI Model can help to assess performance against the current requirements and ensure a highly optimised solution.
What does the WUFI Model measure?
The WUFI model is based on a detailed analysis of the physical processes that affect heat and moisture transfer in building materials, including mass transport, phase changes, and capillary effects.
The software uses a finite-difference numerical approach to solve the equations governing heat and moisture transfer in building materials over time.
This allows for the prediction of how moisture content and temperature within building assemblies will change under different environmental conditions, such as temperature, humidity, and rainfall.
What are the benefits of the WUFI Model’s application to commercial buildings?
Some of the key applications of WUFI in commercial buildings include:
Do you need to use a WUFI Model?
In summary, the WUFI model can be a powerful tool for assessing the performance of building materials and assemblies in commercial buildings, helping to optimise building envelope design, improve energy efficiency, and ensure long-term durability. It is recommended to consult with the qualified energy assessor’s at Certified Energy, to determine the most suitable use of the WUFI model to achieve a code compliant solution for your commercial building project.
