  • PHIUS+ (for Single Family / townhomes)

    Passive House certification requires both a Phius Certified Consultant (CPHC) during design & construction, and a Phius certified Rater during the construction phase to provide third-party verification. There are both program registration fees and consultant fees.

    Phius is the only passive building certification that combines a thorough passive house design verification protocol with a stringent Quality Assurance/Quality Control (QA/QC) program performed onsite by Phius Raters and Verifiers.

    Phius+ requires co-requisite program certification as part of its program. The co-certifications include:

    • ENERGY STAR

    • EPA Indoor airPLUS

    • DOE Zero Energy Ready Home.

    Certification options include a performance-based pathway and a prescriptive pathway though Phius CORE certification program.

    Additionally, projects may opt to certify under Phius ZERO, which is built upon the CORE program but focuses on passive conservation measures first but sets the net source energy target at ZERO, does not allow for fossil-fuel combustion on site, and provides both on-site and off-site renewable energy options to get to ZERO.

    Visit Phius for more info.

  • Passive House (PHI-Passive House Institute)

    Not to be confused with Passive House Institute US, Passive House Institute is an independent research institute that has played a critical role in the development of the Passive House concept. It is the only internationally recognized, performance-based energy standard in construction, including the US. For a building to be considered a Passive House, it must meet the following criteria:

    • A maximum space heating energy demand of 15kWh per square meter of net living space per year or 10W per square meter peak demand. Alternatively in climates where active cooling is needed, the Space Cooling Energy Demand roughly matches the aforementioned space heating requirement.

    • Renewable Primary Energy Demand used for all domestic applications must not exceed 60kWh per square meter of treated floor area per year for Passive House Classic.

    • A maximum 0.6 air changes per hour at 50 pascals pressure (ACH50), as verified by on-site pressure testing.

    • Thermal comfort must be met for all living areas during winter as well as summer, with not more than 10% of the hours in a given year over 25 degrees C.

    Passive House buildings are planned, optimized, and verified with the Passive House Planning Package (PHPP).
