- Employs continuous insulation throughout its entire envelope without any thermal bridging.
- Creates an extremely airtight building envelope, preventing infiltration of outside air and loss of conditioned air.
- Employs high-performance windows (double or triple-paned) and doors - solar gain is managed to exploit the sun's energy for heating purposes in the heating season and to minimize overheating during the cooling season.
- Uses some form of balanced heat- and moisture-recovery ventilation.
- Uses a minimal space conditioning system.
Phius-certified buildings go through a rigorous quality control process, ensuring safety for the environment and the building inhabitants.
Phius buildings have been proven to be more resilient in the event of natural disasters, such as wildfires and extreme heat and cold events.
Superb indoor air quality is a prerequisite for Phius certification – you can count on a healthy environment.
The holistic design of Phius buildings make them uniquely built for the long haul.
Superinsulation and efficient mechanical systems help maintain the strict comfort standards required for Phius certification.
Phius projects require minimal to no additional upfront costs, while guaranteeing substantial energy cost savings in the future.
Quality Assurance Professionals
For myself and for us at Architectural Resource, we feel that Phius presents the best possible, most rigorous, building science-based path forward to a brighter future. One where our homes are not a part of the problem, but rather a part of the solution.
