Electrify

Phius CORE allows for fossil-fueled combustion on-site, but requires electrification readiness for any combustion equipment. Phius CORE Prescriptive advances electrification efforts by banning fossil-fueled combustion on site.

Support Electrification

Are Ready for ZERO

Passive building provides a proven methodology for designing a net zero energy building. The first step is conservation — first through passive measures, then through active measures. Phius CORE targets the sweet spot for on-site conservation through both passive and active strategies.

Lay the Foundation for ZERO

Help the Grid

Projects that meet Phius CORE achieve significant load reduction relative to a code-built building. This reduction lessens reliance on continuous support from the electric grid and can support load flexibility. This flexibility helps facilitate the integration of more intermittent renewable energy and reduces the total grid capacity needed to meet peak loads.
