SGH collaborated with the project team on the design and construction of the building enclosure. As the PHIUS+ Verifier, we also conducted and witnessed performance testing for the Living & Learning building.

Highlights of our work include the following:

• Reviewed the building enclosure design and provided recommendations for improving energy efficiency, airtightness, watertightness, and constructability
• Helped detail transitions to reduce thermal bridging and air leakage as required for PHIUS+ certification
• Established PHIUS+ performance requirements, roles and responsibilities, testing protocol, and procedures for documenting progress and issues
• Reviewed enclosure-related submittals and provided recommendations to ensure the building enclosure systems met the overall project design intent and performance requirements
• Observed construction of the building enclosure and mechanical systems, conducted an infrared survey of exterior walls and roofs, and performed whole-building airtightness testing to compare with PHIUS+ certification and project requirements
• Witnessed testing and balancing of the mechanical system, verified air flows met PHIUS+ certification requirements, and reported power consumption to the Passive House Design consultant
• Prepared a PHIUS+ on-site verification package for submission to PHIUS
