Phius CORE REVIVE is Phius' legacy certification for retrofitting existing buildings. In order to achieve our carbon reduction goals, many existing buildings must be revived to meet passive building levels of performance. Enclosure focused passive building retrofits provide substantial benefits such as comfort, indoor air quality, lower utility bills, decreased impact on the electric grid, and less renewable energy necessary to get to ZERO.
Phius ZERO REVIVE is Phius' zero energy standard for retrofitting existing buildings. Built upon CORE REVIVE, it is arguably the most stringent of the standards, setting the net source energy target at ZERO, not allowing for fossil-fueled combustion on site, and providing both on-site and off-site renewable energy options to get to ZERO. In order to achieve our carbon reduction goals, many existing buildings must be revived to zero energy passive buildings.
