WUFI Manual |
This manual describes the installation, shows the first steps with the software and gives an overview about the features of WUFI. Using a building envelope as an example, it is shown how to create a construction, how to set boundary, surface transfer and initial conditions and finally how to calculate and assess this example. Download the file WUFI_Pro_4_Manual.pdf (4.5 MB) and read it with the Adobe Acrobat Reader. |

WUFI 2D Example |
This introduction will show you how to model a building component in WUFI 2D, how to specify boundary, surface transfer and initial
conditions, how to perform the calculation and how to analyse the results. As an example illustrating each step, we will analyse the hygrothermal behavior of a concrete ceiling supported by a brick wall with exterior insulation. Download the file WUFI2D 3.2 Example.pdf (2.9 MB) and read it with the Adobe Acrobat Reader. |

Weather file list for |
This *.KMZ file displays the locations of the weather files registered in WUFI's database by feeding them to
Google Earth (which you must have installed). Some of these weather files are included with WUFI; the others must be purchased from the respective vendor, but they can then immediately be used for WUFI calculations, without further configuration. A click on one of the WUFI icons will display some information about the respective weather file. Download the file WUFI Weather Data.kmz (142 KB) and run it with a double-click. Update: 06 May 2009 |

Weather data |
The 1991 weather data measured in Holzkirchen can be considered representative for Holzkirchen climate
conditions. They are included in the WUFI installation packages, but IBP also offers them separately
for general purposes. Download the file ibp1991.zip (260 kB) and unzip it. |
|
HygroApprox |
The software tool HygroApprox allows simple approximation of certain hygrothermal material parameters
from standard parameters. The current version offers approximation of the liquid transport coefficients
Dw and of the moisture storage function. The compressed archive hygroapprox.zip (354 kB) contains the program and two sample data sets. (Sorry - currently in German only and no documentation yet.) |
