Installing WUFI Plus

The menu-driven PC program WUFI® (Wärme und Feuchte instationär - Transient Heat and Moisture), developed by IBP and validated using data derived from outdoor and laboratory tests, allows realistic calculation of the transient hygrothermal behaviour of multi-layer building components exposed to natural climate conditions. WUFI® is based on the newest findings regarding vapour diffusion and liquid transport in building materials.

WUFI® only requires standard material properties and easy-to-determine moisture storage and liquid transport functions.

WUFI® can use measured weather data - including driving rain and solar radiation - as boundary conditions, thus allowing realistic investigations on the behaviour of the component under exposure to natural weather.

WUFI® can be used for assessing

• the indoor climate conditions depending on how the building is used
• the energy consumption for heating, cooling and ventilation
• the danger of interstitial condensation
• the effect of repair and retrofit measures to the indoor climate
• the hygrothermal performance of roof and wall assemblies under defined use or in different climate zones.

Computer Requirements:

• IBM-compatible Pentium-class computer. High speed is recommended for performance.
• At least 512 MB of random access memory (RAM).
• Microsoft Windows XPTM
• Hard disk drive with at least 100 megabytes of available disk space.
• Additional 500 megabytes for the calculation results

Installing the Program:

In order to install WUFI-Plus you need to have the system administrator rights. Put the program installation CD in the appropriate CD drive and follow the instructions.
