WUFI® is a family of software products that allows realistic calculation of the transient coupled one- and twodimensional heat and moisture transport in walls and other multi-layer building components exposed to natural weather. WUFI® is an acronym for Wärme Und Feuchte Instationär—which, translated, means heat and moisture transiency. WUFI® software uses the latest findings regarding vapor diffusion and moisture transport in building materials. The software has been validated by detailed comparison with measurements obtained in the laboratory and on IBP’s outdoor testing field.
Component simulation and building simulation
The various versions of the WUFI® software family perform coupled heat and moisture calculations under local climate conditions and for materials, multilayer components, and even whole buildings. Through WUFI® simulation of heat and moisture transport, users can, while still in the planning phases, optimize designs and identify risks and problems.
The fundamentals required for practical application of heat and moisture transfer calculations and the application of WUFI® software for building physics investigations are presented in numerous publications by staff at the Fraunhofer Institute for Building Physics (IBP) and by other institutions. The numerous examples of applications that use WUFI®, together with many publications on the topic of hygrothermics, are located here.
Instruction manuals and handbooks
This link leads to numerous instruction manuals and handbooks for users who are just starting with WUFI®, as well for advanced users with specific questions.
The Fraunhofer Institute for Building Physics offers general workshops on WUFI® at regular intervals. There is one workshop for WUFI® beginners and for those with a general interest in WUFI®, and there is another workshop for existing users who want more advanced training. There are separate workshops that focus on WUFI® 2D, WUFI® Plus, and WUFI® Passive. Since WUFI® developers themselves teach the workshops, a high quality experience can be expected.
The FAQ section provides numerous answers to our most frequently asked questions – especially those relating to purchasing and getting started with WUFI®. There you will find, for example, extensive information on what WUFI® programs and licenses are available, what databases they use, how to purchase and pay for the software, and what the system requirements are.
If you already use WUFI® and have specific questions about the software, there are a number of help sources available, such as instruction manuals, tutorials, and the WUFI® forum. An overview of these sources can be found under support.more
The new versions WUFI® Plus 3.0.1 and WUFI® Passive 3.0.1 have now been released. Please find an overview of alterations and setup instructions in the update overview.
Free-of-charge updates are listed on the WUFI® online shop in the section „my orders“. The displayed link allows you to download the respective latest version which can be update to for free. Please extract the file and install the software using your existing licence number (usually identified automatically). Earlier versions don't have to be uninstalled. Chargeable upgrades will be displayed at the online shop when you log in with your WUFI® account.more
20 years ago, in fall of 1995, the first WUFI®-Seminar was held in Holzkirchen, Germany. By that time the selling of WUFI® 1D (nowadays WUFI® Pro) started. We want to celebrate this anniversary by giving you 20% discount on all WUFI® software and all WUFI® upgrades within the next two months.
The campaign runs between October 15 and December 15, 2015.
During the campaign, the upgrade of WUFI® Pro 5.3 to WUFI® Pro 6.0 will be included in the new purchase price of 2300€. You will be informed via E-Mail as soon as the upgrade is available (expected release at the end of November 2015).
For further information, please visit the online shop from October 15 onwards.
As part of the launch of the updated versions of WUFI® Plus and WUFI®Passive, the no-cost WUFI® Plus Free and WUFI® Passive Free packages and the WUFI® product website have been updated. The updated software and website offer new and enhanced content and features.more
