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.
We want to make you aware, that in a few weeks, March the 8th and 9th 2018 our WUFI® 2D workshop held in English starts in Holzkirchen, Germany. Find more information here.
Please contact firstname.lastname@example.org for registration.more
There are still places available for our WUFI® Pro workshop for advanced users in April 19th and 20th.
Find more information here.
The new version 4.0 of our hygrothermal simulation software WUFI® 2D can now be obtained at the online shop. Version 4.0 shows many new features and improvements:more
When purchasing a product from the WUFI® family, only technical support is included (questions about installation, program errors, etc.). Now we have extended this offer due to multiple requests from our clients!
As of now you can also purchase WUFI® support packages in our online shop.more
Moisture management in buildings is a trending topic, as moisture related problems not only affect old buildings, but energy efficient new ones as well. In the United States, roughly 50% of all households reported the prevalence of dampness and mold. European households discovered these same issues, reporting them in about 20% of households.
The Fraunhofer Institute for Building Physics IBP has conducted research in this field for many years, and is dedicated to solving to these problems by providing software, experience, and solutions to organizations such as ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers). With contributions of Fraunhofer experts, a new chapter on moisture management in buildings was developed for ASHRAE’s Handbook of Fundamentals.more
