= Welcome to WUFI =

WUFI is a Windows-based program for the hygrothermal (i.e., heat and moisture) analysis
of building envelope constructions. WUFI is an easy-to-use, menu-driven program for use
on a personal computer which can provide customized solutions to moisture engineering
and damage assessment problems for various building envelope systems.


The WUFI simulation model is a transient heat and mass transfer model which can
be used to assess the heat and moisture distributions for a wide range of building
material classes and climatic conditions.


With WUFI you can estimate the drying times of masonry and lightweight structures
with trapped or concealed construction moisture, investigate the danger of interstitial
condensation or study the influence of driving rain on exterior building components.
The program can also help to select repair and retrofit strategies with respect to the
hygrothermal response of particular roof or wall assemblies subjected to various climates.
This allows the comparison and ranking of different designs with respect to total
hygrothermal performance.


In addition, WUFI provides an instructive overview of the complex moisture
transport phenomena occurring in construction assemblies, making the basic principles
and interactions present during moisture transport more accessible and allowing both
designers and architects insight into design decisions.


This design tool can also aid the development and optimization of innovative building
materials and components. One example is that WUFI simulations led to the
development of the smart vapor retarder; a successful application of a software tool
to a practical moisture control problem.

== What is WUFI? ==

WUFI is the acronym for "Wärme- und Feuchtetransport instationär" ("Transient
Heat and Moisture Transport").



WUFI is designed to calculate the simultaneous heat and moisture transport in
one- or two-dimensional building components.



A comfortable Windows® user interface allows quick set-up of a calculation
project, easy change of parameters for numerical experiments and comfortable
viewing of the results as graphics or as an animation.



The physical and numerical ideas underlying WUFI are developed and discussed
in the doctoral thesis:


Künzel, H.M.: 
Verfahren zur ein- und zweidimensionalen Berechnung des gekoppelten Wärme- und
Feuchtetransports in Bauteilen mit einfachen Kennwerten. 
Dissertation Universität Stuttgart 1994 
  
(may be ordered from IBP: http://www.hoki.ibp.fhg.de/index.html )
  
or 
  
Künzel, H.M.: 
Simultaneous Heat and Moisture Transport in Building Components. 
One- and two-dimensional calculation using simple parameters. 
IRB Verlag 1995 
  
(may be ordered from IRB Verlag, Stuttgart: http://www.irb.fhg.de ).



In the calculation of heat transport, WUFI takes into account:

* thermal conduction
* enthalpy flows through moisture movement with phase change
* short-wave solar radiation
* nighttime long-wave radiation cooling (optional, and with
[[Details:TRY-File | TRY]] or [[Details:DAT-File | DAT]] weather data only).


Convective heat transport by air flows has been disregarded, since it is usually
difficult to quantify. As it is rarely one-dimensional, including it in WUFI-1D
would not be very useful. A future WUFI-2D version may include it.



The vapor transport mechanisms included in WUFI are:

* vapor diffusion
* solution diffusion


Again, convective vapor transport by air flows has been ignored.



The liquid transport mechanisms taken into account are:

* capillary conduction
* surface diffusion.


Seepage flow through gravitation, hydraulic flow through pressure differentials,
as well as electrokinetic and osmotic effects have not been included.



The choice of temperature and relative humidity as driving potentials allows the
use of simple, easily comprehensible storage and transport coefficients. These
can thus readily be derived from standard material data if no measured data are
available and utmost precision of the results is not required.



The boundary conditions for each time step are expressed in terms of meteorological
data (temperature, relative humidity, driving rain, radiation), since in building
physics these are the relevant parameters specifying the conditions at surfaces
exposed to natural weather. 
However, conditions for laboratory experiments (e.g. imbibition measurements) can
also be expressed as 'meteorological' data.
