For non-commercial purposes we offer a version WUFI light with a somewhat reduced
set of features for free download. Please go to our
online shop for downloading the program (free
registration required) The free version has a limited lifetime of one year. For users in North America (USA and Canada), an American version has been developed. This version is available from our online shop as well (free registration required). |

Film Viewer |
This film viewer allows you to view animated WUFI results on computers which have no WUFI installed. You can use it for
stand-alone presentations, embed it in a PowerPoint presentation or burn it on a self-starting presentation CD. Instructions
are included. Download the file Animation1D_StandAlone.zip (2.1 MB) and unzip it into the desired directory. Update: 19 January 2011 |

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-5_Manual.pdf (5.5 MB) and read it with the Adobe Acrobat Reader. |

WUFI 2D Online Help |
The current version of WUFI 2D's online help is separately available for download. Currently it is identical with the online help included in the installation package of WUFI 2D version 3.2. Download the file WUFI2D.chm (806 KB) and open it with a double-click. Last update: 17 Apr 2007. |

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. |

Example4PostProc |
This postprocessor demonstrates how simple it is to integrate a postprocessor into WUFI.
It only displays the data it receives from WUFI; it does not perform any evaluation.
Instructions and documentation are included. Download the file Example4PostProc.zip (579 KB) and unzip it into the desired folder. Edit the file ID_100.ini with a text editor, entering the paths to the current location of the postprocessor and its program icon, and then copy the file into WUFI's PostProc folder. On the next start, WUFI will automatically display this postprocessor in its postprocessor bar. New: 25 January 2011. |

WUFI-Bio 3.1 |
The postprocessor WUFI-Bio allows to assess the risk of mould growth, based on measured or computed local climate conditions.
 Download the file Install_WUFIBio.zip (8.7 MB), unzip it and run the installer Install_WUFIBio.exe. This will install the postprocessor and integrate it into WUFI. (Note: the current download is a pre-release version of the new WUFI-Bio 3.1. The finished release 3.1 will include a save function and an updated on-line help.) Last update: 11 Jan 2013. |

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 (147 KB) and run it with a double-click.

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.) |
