Phius Certified Builder (CPHB)

Phius Certified Builders are construction professionals trained to meet the challenges of building to the rigorous Phius passive building standard.

Training Schedule

The Role of a CPHB

Phius Certified Builder Training is geared toward construction professionals who would like to take their expertise to the next level.

For a project pursuing Phius Certification, these professionals are critical to ensuring the building is built and operating to the plans and specifications that are design certified by Phius. They are responsible for executing air-sealing and thermal bridge mitigation.

Key Competencies of a CPHB

Building Science Fundamentals

Building Science Fundamentals

Phius professionals learn how controlling moisture, heat, and airflow in buildings define best practices in building design for comfort, efficiency, durability, and air quality.

High-Performance Building Enclosures

High-Performance Building Enclosures

From moisture control strategies to thermal-bridge-free design strategies, passive building places emphasis on getting the enclosure right.

High-Performance Mechanical Systems

High-Performance Mechanical Systems

Balanced ventilation and high-performance heating, cooling, and domestic hot water systems are critical elements of passive building design. Builders must understand how to recognize, handle, and install high performance equipment.

Airtightness Detailing Techniques

Airtightness Detailing Techniques

An airtight enclosure is cornerstone to passive building. Phius Certified Builders learn what materials and techniques can successfully achieve the required level for airtightness and deliver comfort alongside a long-lasting durable enclosure.

Project and Site Management, Risk Mitigation

Project and Site Management, Risk Mitigation

The inclusion of passive building requirements in addition to all the typical project concerns adds additional complexity. The Phius Certified Builder course reduces the learning curve required to successfully integrate this new methodology into existing practice and minimize risk.

Economics, Cost Optimization, and Bidding

Economics, Cost Optimization, and Bidding

Keeping a grip on the economics makes passive projects successful. Phius Certified builders must understand sourcing of varying products, materials, and the climate-specific passive building methodology to understand how to achieve optimal results.
