Superinsulation, air-tight envelopes, high-performance window installation, site management, component sourcing – passive house construction presents special challenges to builders. This PHIUS Certified Builders Training program, offered in partnership with Passive House Institute US (PHIUS), prepares construction professionals to meet the passive house challenge. The program curriculum – developed by a team with twenty successful passive house projects between them – runs from an introduction to design theory and climate-specific detailing to materials, techniques, project management and quality assurance. The course offers real-world experience in the on-site implementation of passive house as well as counseling and advice to both the practical and business concerns specific to passive house. The course covers not only craftsmanship, but also focuses on the risks and liability to the passive house contractor and guidance in both problem solving and (more importantly) problem avoidance. Students who complete the four-day training and pass the qualifying exam become PHIUS Certified Builders.
