WUFI Workshops - (What does WUFI stand for? Wärme Und Feuchte Instationär) WUFI workshops - computer modeling of hygrothermal (moisture and heat) transfer through walls. These workshops, with instruction provided by Oak Ridge National Laboratory (ORNL) of the United States and the Fraunhofer Institute of Building Physics in Germany, are sponsored by the U.S. Department of Energy, the National Institute of Building Sciences (NIBS) /Building Enclosure Technology and Environment Council (BETEC) and others. Each student brings his/her own laptop, receives software with a temporary license, and will run simulations. The computer modeling enables the user to diagnose or design wall configurations within a user-specified geographic region for which NOAA has gathered weather data for decades. Even mold growth in the building can be predicted using this model.
You can download free demo of WUFI-ORNL software from the link below: http://web.ornl.gov/sci/btc/apps/m For a movie that demonstrates the WUFI Pro software, go to this link: http://www.hoki.ibp.fhg.de/wufi/Movie/Movie_Pro_E/Movie_Pro_E.htm For one architect's opinion, this is a link to an article written by Thomas L. Smith, AIA, for Professional Roofing magazine:

WUFI Plus is a new holistic model that takes into account the main hygrothermal effects, like moisture sources and sinks inside a room, moisture input from the envelope due to capillary action, diffusion and vapour ab-/desorption as a response to the exterior and interior climate conditions, heat source and sinks inside the room, heat input from the envelope, the solar energy input through walls and windows and hygrothermal sources and sinks due to natural or mechanical ventilation will be presented. Beside the theoretical background, several practical applications will be shown. Students receive a 13-week temporary license.
This 5th annual international session will be held at the Fraunhofer Institute of Building Physics in Holzkirchen, Germany: It will consist of 3 modules -- you can attend one only, or two or three:
WUFI Standard course, December 3 & 4; WUFI Advanced Workshop, December 7 & 8; and WUFI-2D and WUFI-Plus, December 9 & 10.
The latter two modules are
for previous WUFI graduates or students with equivalent experience in modeling. This year's sessions will be taught by Drs. Hartwig Kuenzel and Andreas Holm of the Fraunhofer Institute of Building Physics (Germany) and Drs. Achilles Karagiozis and André Desjarlais of Oak Ridge National Laboratory (U.S.). Curriculum will include WUFI 4 (1D), WUFI 2D, and the new WUFI Plus. WUFI users will be invited to present. In the middle of the program, some WUFI users will present on interesting cases they have had using WUFI. This advanced workshop is geared around sharing of information. Advanced WUFI Workshop and Conference will be at the Fraunhofer Institute of Building Physics in Holzkirchen, Germany, December 3-10.
Registration information will be available in late March.

There are now two user groups, one started by the Fraunhofer Institute and one started by U.S. WUFI users. Click below to download a Word document containing information:
Besides the 80 or so cities in the WUFI database, there is additional data available from the National Climate Data Center (NCDC). The data is for about 250 U.S. cities and covers about 30 years. You can then use this data in the Weather File Analyzer (comes with your WUFI software) to compute the 90% hot and cold years and convert the files into WUFI-compatible files. They can then be used in WUFI. Here is the link: http://www.ncdc.noaa.gov/oa/ncdc.html Another web site that may be of interest for forensic investigation is Compu-Weather - here is their link:
There is a new web site with lots of information, and a nifty graphic demonstration of WUFI in action. Go here for all the latest information:
