WUFI® 2D expands the scope of WUFI® Pro to two-dimensional analysis. A one dimensional WUFI® Pro analysis cannot be used when regions next to the line of interest have different heat and moisture responses. In particular, two dimensional analyzes are necessary for compliciated geometries, such as building corners, window locations, and foundation connections and when there are non-uniform souces/sinks of heat and moisture.
Compared to WUFI® Pro, the inputs for WUFI® 2D are considerably more complex, and the computational time is also significantly increasing. Given the ease-of-use of WUFI® Pro, it is most desirable to keep the analysis one-dimensional. Indeed many situations, including those with ventilation and rainwater infiltration, can still be effectively analyzed in one dimension. As such, WUFI® 2D should be more generally thought of as a complement and not an alternative to WUFI® Pro.
Evaluation of critical connections
Optimization standard construction details for specific situations
Investigation of damage, particularly in corners, around window frames, and at component connections
Assessment of mold growth associated with thermal bridges
Assigning liability in planning or execution*
Building products companies
Development and optmization of products and systems
Assessment/dimensioning of components in a system (e.g., ETICS)
* Upon evaluating damage in existing structures, if the simulation correctly accounts for uncertainty (e.g., driving rain, leaks in ETICS, and/or convective moisture entry with lightweight components) and does not predict damage, then the workmanship is to blame. On the other hand, if the simulation predicts that damage can occur, then poor design is to blame.
The evaluation of results is the responsiblity of the user and not of the software. Assessing results requires experience and understanding of building science. It is recommended that all users attend a seminar dedicated to WUFI® 2D. The seminars educate users about basic building physics and give confidence for handling the software. In addition, such seminars provide information on new models and evaluation options.
The demo film demonstrates the use of WUFI® 2D.
The WUFI® 2D user-interface is only available in English.
WUFI® 2D can calculate in SI units.
The multi-language material databank has about 600 pre-defined building materials and can also accept user-defined materials. WUFI® 2D contains climate data for about 149 locations (Europe, North America, South America, Japan, and Oceania).
