Phius ZERO for Commercial Buildings

Phius ZERO COMM sets the industry standard for net zero energy design. It defines a conservation-and-quality first approach for zero energy design, placing emphasis on quality, durability, healthy, safety, and cost-optimized conservation.

Phius ZERO COMM

The performance criteria for Phius ZERO COMM is the same as for Phius ZERO 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.
