Phius Certified Builder (CPHB) Training

This training is composed of 8 hours of self-guided content to be completed ahead of attending 8, 3-hour live online training sessions.

The Phius Certified Builder Certification is for tradespeople and construction professionals with field experience in construction and/or high performance building. This training prepares construction professionals to understand passive building techniques — airtight enclosures, high-performance window installation, passive design strategies, field quality assurance, and site management. For a project pursuing Phius Certification, these professionals ensure the building is built and operating to the plans and specifications. They are responsible for executing air-sealing and thermal bridge mitigation.
