WUFI Workshops - (What does WUFI stand for? Wärme Und Feuchte Instationär) WUFI workshops - computer modeling of hygrothermal (moisture and heat) transfer through walls
and roofs. 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
or roof 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://www.ornl.gov/sci/ees/etsd/btric/wufi_software.shtml 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 TRAINER WORKSHOP: NEW! There will be a workshop to train trainers who wish to become an ORNL-certified instructor for WUFI-ORNL seminars. Date of training workshop is September 13-14, 2012. Location to be determined. Prerequisite is to have attended a WUFI workshop and to be a regular user of WUFI. Price to be announced. For further information contact: Manfred Kehrer, KehrerM@ornl.gov , phone: 865 – 576 – 3924. Also please indicate your interest by giving us your contact information on the following clickable form:

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.

The WUFI Pro tab will lead you to a detailed curriculum and current reservation and registration info.
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.
(Prerequisite is previous WUFI Pro workshop or equivalent experience). Each year there is an Advanced WUFI Workshop. In 2012 it will be held on January 30 through February 1in Napa, California, following the ASHRAE conference.
This is a 2-1/2-day workshop consisting of: WUFI 1D Advanced Workshop, WUFI-Plus, WUFI-2D
Click on the blue ADVANCED WUFI Workshop tab to see the 2-1/2-day curriculum and a link to register for the hotel.

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.
This
year the instructors from Oak Ridge National Laboratory will train and
certify others to teach an introductory workshop in WUFI-ORNL. Planned
date is September 13-14, 2012. Details will follow as the course
planning is completed. If you are interested, please fill out the
following form and e-mail it back to Jackie McNabb (instructions are on the
form). She will keep you informed as to date and place and curriculum.
Prerequisite will be a prior WUFI-ORNL / WUFI Pro workshop, and preferably
an advanced workshop.
