WUFI® Plus is the most complete heat and moisture simulation tool widely used and respected in the industry. It is one of the few that can model the complex behaviours of water vapor in building assemblies and envelopes.

In addition to simulating hygrothermal conditions in building components, WUFI also simulates the indoor environment and is therefore suitable for addressing comfort and energy consumption in buildings. Since simulations are based on user-specified climate and on user-defined ventilation, HVAC, and internal loads, the simulations can accurately represent the situation at hand. 

Simulation of the interaction between building usage and system technology allows for integral assessment of indoor climate, hygienic conditions, thermal comfort, indoor air quality, and damage to components as a function of heating and cooling loads and the necessary effort to humidify/dehumidify.

Integrated modules for dynamic analysis of 3-D bodies (e.g., thermal bridges) and for air exchange between conditioned zones and the outside further expand the capabilities of WUFI® Plus.

Besides the dynamic hygrothermal building simulation WUFI Plus can also be used for Passive House design and certification and to verify the summer heat insulation according to German DIN 4108-2 Standard.
