CPHC Program Overview

Key Competencies of CPHCs

Building Energy Modeling and Passive Building Physics

Building Energy Modeling and Passive Building Physics

Understanding passive building physics and the driving factors for losses and gains in a building are essential to climate-appropriate passive building design.

High-Performance Building Enclosure Design

High-Performance Building Enclosure Design

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.

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.

Air-Tightness Detailing

Air-Tightness Detailing

An airtight enclosure is cornerstone to passive design and with applied building science leads to a long-lasting, durable enclosure, comfort, and minimized losses from a leaky building

Cost Optimized, Climate-Specific Design

Cost Optimized, Climate-Specific Design

CPHCs take a deep dive into the Phius standards and passive building methodology to understand how to achieve climate-specific optimized designs.

Assure Quality from Design through Construction

Universities with CPHC Training in Curriculum

Project Management

For a project pursuing Phius Certification, these professionals are critical to ensure the building is designed and detailed utilizing passive building strategies and is compliant with Phius Certification requirements. They are responsible for ensuring the building is compliant with all of Phius' requirements.

Review all Requirements in the Phius Certification Guidebook

Building Energy Modeling

For projects pursuing the performance path (as opposed to the prescriptive path), the CPHC is responsible for modeling the project in WUFI Passive to verify compliance with the specified performance targets throughout design and post-construction.

Learn more about WUFI Passive

Prescriptive Path Compliance

For projects pursuing the prescriptive path, the CPHC is responsible for analyzing the project using the Phius Prescriptive Path checklist and verifying compliance with the specified requirements.
