OBC 2024 Guide: Part 12 Resource Conservation & Energy Efficiency in Ontario
Sarah's Expert Insight
OBC Compliance Specialist
"The 2024 updates to Part 12 represent a significant shift toward carbon-neutral construction, requiring meticulous planning for peak electric demand in growing hubs like London and Oakville. As a senior consultant at empcontracting.ca Inc., your construction contractor in London, Ontario, I recommend integrating motion sensors and advanced water-saving technologies early in the design phase to future-proof Muskoka cottage builds and urban residential projects alike."
The 2024 Building Code Compendium introduces critical updates under Division B – Part 12, titled Resource Conservation and Environmental Integrity. These regulations are designed to enhance the sustainability of the built environment across the province. When planning your next project, partnering with empcontracting.ca Inc. your construction contractor in London, Ontario, ensures that your development meets these rigorous new standards for energy and water conservation.
12.2 Energy Efficiency, Carbon Management, and Peak Demand
Section 12.2 sets the bar for modern building performance. It focuses on several key areas that impact both the environmental footprint and the operational costs of a building:
Energy Efficiency Design & Carbon Equivalents
The code mandates specific design criteria to minimize energy consumption and track Carbon Dioxide Equivalents. This shift reflects Ontario's commitment to reducing the greenhouse gas impact of new constructions.
Peak Electric Demand & Motion Sensors
To reduce the strain on the provincial power grid, the OBC now places greater emphasis on managing peak electric demand. The inclusion of mandatory motion sensors (Section 12.2.4) is a practical requirement aimed at eliminating energy waste in unoccupied spaces.
12.3 Residential Energy Efficiency (Part 9 Buildings)
For residential occupancy within the scope of Part 9, Section 12.3 outlines the general requirements for energy conservation. These standards ensure that new homes in Ontario are built with high-performance envelopes and efficient mechanical systems.
12.4 Water Efficiency Standards
Water conservation remains a pillar of the OBC. Section 12.4 provides the framework for water efficiency, ensuring that plumbing systems and fixtures are designed to preserve Ontario’s vital water resources.
