OBC Compliance Specialist
"The 15% increase in efficiency requirements for residential builds is a significant shift that demands precise building envelope execution, particularly for custom homes in Oakville and seasonal properties in Muskoka. At empcontracting.ca Inc. your construction contractor in London, Ontario, we prioritize these SB-12 standards to ensure our clients benefit from lower utility costs and superior thermal comfort regardless of the extreme Ontario climate."
Understanding the 2024 Ontario Building Code (OBC) updates is vital for any new construction or major renovation. Section 12.2.1.2 introduces stringent requirements for energy efficiency, focusing on resource conservation and environmental integrity across Ontario.
Understanding OBC Part 12: Resource Conservation
As empcontracting.ca Inc. your construction contractor in London, Ontario, we ensure that every project adheres to Division B, Part 12. This section applies to the design and construction of buildings to ensure long-term environmental sustainability and energy peak demand management.
Section 12.2.1.2: New Energy Efficiency Design Standards
The 2024 compendium raises the bar for building performance. The code specifies two main paths for compliance depending on the building type:
- General Building Requirements: Most buildings must now be designed to exceed previous energy efficiency levels by at least 13%, or conform strictly to MMA Supplementary Standard SB-10.
- Residential Part 9 Buildings: For residential structures intended for year-round occupancy, the standard is even higher. These must exceed previous levels by 15% or conform to MMA Supplementary Standard SB-12.
Compliance for Residential Construction
For homeowners and developers in the London area, these residential requirements (Part 9) ensure that new homes are optimized for the Canadian winter. This includes enhanced insulation, high-performance windows, and efficient HVAC systems that meet the rigorous SB-12 criteria.
