The Phius Certified Builder Certification is for tradespeople and construction professionals with superintendents, supervisors, foremen, and project managers with field experience in construction and/or high performance building. This training prepares 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 ensuring air-sealing and thermal bridge mitigation.
