2024 Ontario Building Code Guide: SB-10 Energy Efficiency and Lighting Control Standards
Sarah's Expert Insight
OBC Compliance Specialist
"In high-growth areas like London and Oakville, staying ahead of SB-10 compliance for carbon emissions and peak demand is crucial for passing inspections and reducing long-term utility costs. As the lead at empcontracting.ca Inc. your construction contractor in London, Ontario, I advise clients that while motion sensors are excellent for energy savings, they must be meticulously planned to ensure they never compromise the safety of exit routes or emergency lighting paths."
Navigating Energy Efficiency Standards in the 2024 OBC
Understanding the complexities of the 2024 Ontario Building Code (OBC) is vital for ensuring compliance and sustainability in modern developments. At empcontracting.ca Inc. your construction contractor in London, Ontario, we specialize in implementing these technical requirements for commercial and residential projects.
OBC 12.2.2 & 12.2.3: Carbon Emissions and Peak Electric Demand
Most buildings are now required to conform to the MMA Supplementary Standard SB-10, which dictates stringent requirements for Carbon Dioxide Equivalents (CO2e) and peak electric demand. These regulations aim to reduce the environmental footprint of Ontario's built environment. However, the code provides specific exemptions for:
- Farm buildings
- Buildings without electrical power or fossil fuel usage
- Seasonal recreational buildings (Sections 9.37 or 9.39)
- Part 9 residential buildings intended for continuous winter occupancy
OBC 12.2.4: Regulations for Motion Sensor Installation
While motion sensors are a cornerstone of energy-efficient design, the OBC regulates their placement to ensure occupant safety. According to Article 12.2.4.1., motion sensors are permitted for minimum illumination levels except in the following critical areas:
- Designated exits
- Corridors serving patients or residents in Group B medical or care facilities
- Emergency lighting systems (strictly prohibited)
When installed in public corridors, the code mandates that motion sensors must include fail-safe operation and illumination timers set to a minimum of 15 minutes to prevent sudden darkness in high-traffic areas.
