Verifier Training Earns

14 RESNET CEU 18 CPHC CEU

Passive building is growing, and the fastest-growing market segment is multifamily housing (affordable and market rate) and commercial buildings. This 2-1/2-day training prepares third-party Quality Assurance and onsite verification professionals to understand the application of passive building and verification principles for multifamily and commercial projects pursuing PHIUS+ Certification. 

  • Large building enclosure integrity design strategies
  • Passive building mechanical/ventilation systems
  • On-site verification of passive building construction features
  • Large building/multi-fan blower door testing protocols

Additionally, students will learn the specific requirements of the newly released PHIUS+ Multifamily Certification Standard v2.0 for performance and on-site verification of multifamily buildings pursuing certification under the PHIUS+ program.

The course concludes with an exam. Successfully completing the course and exam qualifies the trainee as a PHIUS+ Verifier. 

Please note that Certified Passive House Consultants (CPHC®) are eligible to become PHIUS+ Verifiers, however they cannot verify their own projects.
