Energy Efficiency, Carbon Dioxide Equivalents and Peak Electric Demand

(1)Reserved.

(2)Except as provided in Sentences (3) and (4), the energy efficiency of all buildings shall

• (a) be designed to exceed by not less than 13% the energy efficiency levels required by Sentence 12.2.1.1.(2) of O. Reg. 332/12 (Building Code) as it read on December 31, 2024, or
• (b) conform to Division 1 and Division 3 or 5 of MMA Supplementary Standard SB-10, "Energy Efficiency Requirements."

(3)Except as provided in Sentence (4), the energy efficiency of a building or part of a building of residential occupancy that is within the scope of Part 9 and is intended for occupancy on a continuing basis during the winter months shall

• (a) be designed to exceed by not less than 15% the energy efficiency levels required by Sentence 12.2.1.1.(3) of O. Reg. 332/12 (Building Code) as it read on December 31, 2024, or
• (b) conform to Chapters 1 and 3 of MMA Supplementary Standard SB-12, "Energy Efficiency for Housing."

(4)This Article does not apply to

• (a) a farm building,
• (b) a building that does not use electrical power or fossil fuel, or
• (c) a seasonal recreational building described in Section 9.37. or 9.39.

(1)Except as provided in Sentence (2), all buildings shall be designed to conform to the CO2e emission requirements set out in MMA Supplementary Standard SB-10, "Energy Efficiency Requirements."

(2)This Article does not apply to

• (a) a building or part of a building of residential occupancy that is within the scope of Part 9 and is intended for occupancy on a continuing basis during the winter months,
• (b) a farm building,
• (c) a building that does not use electrical power or fossil fuel, or
• (d) a seasonal recreational building described in Section 9.37. or 9.39.

(1)Except as provided in Sentence (2), all buildings shall be designed to conform to the peak electric demand requirements set out in MMA Supplementary Standard SB-10, "Energy Efficiency Requirements."

(2)This Article does not apply to

• (a) a building or part of a building of residential occupancy that is within the scope of Part 9 and is intended for occupancy on a continuing basis during the winter months,
• (b) a farm building,
• (c) a building that does not use electrical power or fossil fuel, or
• (d) a seasonal recreational building described in Section 9.37. or 9.39.

(1)Lighting installed to provide the minimum illumination levels required by this Code may be controlled by motion sensors except where the lighting

• (a) is installed in an exit,
• (b) is installed in a corridor serving patients or residents in a Group B, Division 2 or Division 3 occupancy, or
• (c) is required to conform to Sentence 3.2.7.1.(10).

(2)Where motion sensors are used to control minimum lighting in a public corridor or corridor providing access to exit for the public, the motion sensors shall be installed with switch controllers equipped for fail-safe operation and illumination timers set for a minimum 15-minute duration.

(3)A motion sensor shall not be used to control emergency lighting.
