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 Pro: April 9-10 SW Downtown Portland, Oregon. See below WUFI Pro tab to link to pages with information. September 16-17: Toledo, Ohio November 18-19: New Orleans, Louisiana
* You will be notified promptly of any
cancellations or schedule changes. If a program is cancelled or postponed
we will refund registration fees but cannot be held responsible for any
other related costs, charges, or expenses, including cancellation/change
charges assessed by airlines or travel agencies. Refunds of registration
fees, when cancelled by the registrant, are 90% refundable if notice is
given via fax or e-mail prior to 30 days before the workshop.

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.
Each year there is and Advanced WUFI Workshop where students can attend a combination of the following:
WUFI (Pro) Standard course, WUFI Advanced Workshop, WUFI-2D, WUFI-Plus
The latter three modules are
for previous WUFI graduates or students with equivalent experience in modeling. Curriculum will include WUFI Pro, Version 5 (1D), WUFI 2D, and the new WUFI Plus. WUFI users will be invited to present on interesting cases they have had using WUFI. This advanced workshop is geared around sharing of information. Date and location of next Advanced workshops to be determined.

RESERVE NOW, PAY LATER! Feel free to ask questions; just e-mail jackiebh@section08.com. Click on the blue tabs above for lengthier descriptions, registration forms and brochures for each workshop or conference
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:

2D simulations are required to evaluate the hygrothermal performance at
thermal bridges, joints, foundations, corners, etc. The WUFI-2D Course
includes hands-on project work and practical application cases as well as
information on material anisotropy and differences with 1D simulations.
