CORE REVIVE sets aggressive performance targets to leave no cost-effective conservation measures on the table. It targets a level that is rigorous but attainable with conservation measures alone.
Phius CORE REVIVE is available for all retrofit projects that wish to pursue the performance path.
Certification under Phius CORE Prescriptive is available to retrofits, but limited to single-family dwellings – detached or attached housing such as side-by-side duplexes or townhomes.
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.
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.
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.
