The Phius CORE Prescriptive program is limited to single family detached residences, townhomes, and duplexes.
For townhomes and duplexes, only vertical partitions are allowed, i.e. only side-by-side projects are allowed. Stacked units are not eligible for this program.
Passive conservation strategies, also referred to as passive building principles, reduce heating and cooling demands on an annual and peak basis. They include improved thermal performance of the building enclosure, minimized thermal bridging, high performance windows, optimized solar gain, air-tightness, and balanced ventilation with heat recovery. For the prescriptive program, Phius sets climate-specific requirements on each of these individual strategies with an option for some tradeoffs. Specifics can be found in the Phius CORE Prescriptive Checklist or Snapshot.
