Commercial Building Standards

Phius CORE COMM

Phius CORE COMM is Phius’ conservation and quality-focused certification for non-residential buildings. It targets performance that is challenging but achievable with conservation measures only and has a performance path for all buildings. With different usage patterns, varying construction details, intermittent occupancy and often high ventilation loads, the optimized performance targets for non-residential buildings are factored slightly differently than residential.

Phius ZERO COMM

Phius ZERO COMM is Phius’ zero energy standard for non-residential buildings. It is built upon CORE COMM, utilizing the same focus on passive conservation measures first but sets the net source energy target at ZERO, does not allow for fossil-fueled combustion on site, and provides both on-site and off-site renewable energy options to get to ZERO.
