The release of the climate-specific, cost-optimized PHIUS+ 2015 Passive Building Standard in March of 2015 by Passive House Institute US (PHIUS) ignited the tremendous growth of passive building from coast to coast, with the most significant gains occurring in the multifamily housing (affordable and market rate) and commercial building sectors. PHIUS+ Certified and Pre-Certified projects now total more than 1 million square feet across 1,200 units nationwide.

PHIUS+ Verifiers perform third-party Quality Assurance and onsite verification for multifamily and commercial passive building projects pursuing PHIUS+ Certification. Verifiers are well versed in the specific requirements of the PHIUS+ Multifamily Certification Standard v2.0 for performance and on-site verification of multifamily buildings pursuing certification under the PHIUS+ program.

PHIUS+ Verifiers are equipped with the skills necessary to achieve:

  • 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.
