Phius CORE COMM
The performance criteria for Phius CORE COMM is the same as for Phius CORE apart from the specific Source Energy metric. The Source Energy limit for non-residential buildings is proportional to floor area, rather than occupancy. There may be additional differences that require additional documentation for Phius Certification.
Compared to residential projects, the energy models for non-residential projects need more detailed information on lighting systems, usage patterns, plug loads, and custom internal heat gains.
