Phius Certified Builder Training and Certification Exam | February 2026

The new training content is updated to reflect the latest passive building best practices and strategies. The new curriculum also has an increased focus on multifamily buildings, as they continue increasing in prominence in the passive building sector.

The training includes 10-15 hours of self-guided training to be completed prior to the in-person instruction. The self-guided training will introduce the foundational theories and concepts of the course, and the in-person, instructor-led portion will focus on real-world application.
