Software
The BEopt™ (Building Energy Optimization Tool) software provides capabilities to evaluate residential building designs and identify cost-optimal efficiency packages at various levels of whole-house energy savings along the path to zero net energy.
The Department of Hygrothermics at Fraunhofer IBP has developed the WUFI® software family for state-of-the-art hygrothermic analysis. WUFI® performs dynamic simulations of coupled heat and moisture transfer. The methods have been validated world wide and provide realistic simulation of hygrothermal conditions in building components and buildings under actual climate conditions.
