The total glazed area may not exceed 18% of the conditioned floor area using the prescriptive method

SHGC (for all fenestration including skylights) is 0.30 W/m2.k for climate zones 1-3. No SHGC requirement for other zones

Skylights

Skylights individually are 0.75 W/m2.k zones 1-2, 0.65 W/m2.k zone 3 and 0.60 W/m2.k zones 4-8

Air Leakage

7 ACH at 50Pa. The thermal envelope must be verified even when using the perscriptive method

Space Heating System

At least one thermostat shall be provided for each separate heating and cooling system.

Specific requirements exist for ducts, piping, ventilation, pool systems and snow melt systems

Requirements are relative to equipment size and building type.

Water Heating System

All circulating service hot water piping shall be insulated to at least R-2 and have automatic or accessible manual switches to turn off the pump when the system is not in use

Lighting

A minimum 50% of lamps in permanently installed lighting fixtures shall be high-efficacy lamps.

Renewable Energy

Pools deriving >60% heating energy from site-recovered or solar energy are exempt from pool specific energy saving measures

End-uses considered:

Space cooling, Space heating, Water heating, Ventilation, Lighting interior, Lighting exterior

Performance Compliance path

Not a requirement / performance based elements are based on a reference model and are relative to energy costs

End-uses considered:

Water heating, Ventilation, Space heating, Space cooling, Lighting interior, Equipment
