WUFI Passive Training
PHIUS offers WUFI® Passive workshops for CPHCs and other professionals who have a solid grounding in energy modeling and/or the other WUFI products available from Fraunhofer. For more information, visit the WUFI Passive Training page.
WUFI® Passive is a powerful user-friendly passive building energy modeling software tool that is uniquely suited to the North American market.
Fraunhofer IBP collaborated with PHIUS and Owens Corning to develop WUFI Passive using PHIUS data and expertise to produce a tool suited to North America's varying climate zones. WUFI Passive dramatically improves the quality and efficiency of the design process for Certified Passive House Consultants (CPHC®). Since 2013, PHIUS CPHC training has included in-class instruction on WUFI Passive. PHIUS also offers standalone WUFI Passive trainings (see sidebar).
