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 free
software, 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.

WUFI Plus: New!

WUFI Plus is a whole building
simulation model that solves for the heat and moisture balances
in buildings. It solves all the wall, roof and
basement (simplified for basements) components and the indoor conditions
with different heat and air conditioning
approaches.
The advantage for all the existing WUFI users is that it employs the
same structure we have used so far for the 1-D. Users can become whole building
energy and moisture experts at the same time. Background:
The hygrothermal behaviour of a building component that is exposed to
weather is an important aspect of the
overall performance of a building. Today the hygric transport phenomena
through a building envelope are well
understood and a realistic assessment of all relevant effects can be
carried out by one of the numerous models and
computer programs, that have been developed in different countries over
the last years. The calculation of the
hygrothermal performance of a part of the envelope is state-of-the-art,
but until now the total behaviour of the actual whole
building is not accounted for. Its importance is increasing as modern
dwellings become more airtight and show
elevated indoor humidity levels.
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.
Prerequisite: WUFI
Pro.
Reviews of first WUFI
Plus training:
“This breaks new ground
for energy, IAQ & Building Envelope studies. Practitioners who are not
using WUFI Plus will end up relegated to being ‘also rans’.” – Roger
Morse, Morse Zehnter Associates
“A valuable robust
tool matches with first rate instruction.” – Lee Durston, BCRA Design
“The
new WUFI Plus software is a great analytical tool for engineers and
architects. Expanding on the detailed capabilities and ease-of-use from
WUFI Pro, Hartwig, Achilles and Andreas have exceeded expectations
again….The 2-day WUFI Plus course was well done: demonstrating not only
by hands-on examples, but also providing thorough validation and
background information needed to understand its capabilities. I highly
recommend this course for advanced users of WUFI wanting to take their
skills to the next level.” -- Rick Duncan
ADVANCED WUFI
Conference 2008 (Prerequisite WUFI Pro):
December 1-2, 2008 Napa, CA
This 4th annual international session is for previous WUFI graduates or students with
equivalent experience in
modeling. This year's 5-day session 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.
Click here for a
representative program from 2007. In the middle of the program, some WUFI
users will present on interesting cases they have had using WUFI.
This conference is geared around sharing of information.

WUFI User Groups -
There are now two user groups, one started by the Fraunhofer Institute
and one started by U.S. WUFI users.

Weather Data -
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
he
files into WUFI-compatible files. They can then be used in WUFI.
