"Meeting the RSI 0.62 insulation and brushless DC motor mandates is essential for optimizing thermal performance in London's variable climate. At empcontracting.ca Inc. your construction contractor in London, Ontario, we find that implementing these kitchen and laundry energy options during the initial build phase provides our Oakville and Muskoka clients with the necessary infrastructure to adapt to evolving energy trends without costly future retrofits."
Understanding the latest updates to the 2024 Ontario Building Code (OBC) is vital for any renovation or new construction project. As empcontracting.ca Inc. your construction contractor in London, Ontario, we ensure every project meets these rigorous efficiency standards to provide long-term value and comfort for our clients.
HVAC and Hot Water Energy Standards
Hot Water Tank Insulation Requirements
Per Section 12.3.1.4, the OBC now mandates that the inlet pipe of a hot water storage tank (between the heat trap and the tank) in a non-recirculating system must be insulated. The insulation must provide a thermal resistance of no less than RSI 0.62, which is critical for reducing standby heat loss and lowering utility bills.
Energy-Efficient Furnace Motors
Modern residential furnaces serving individual dwelling units are now required by Section 12.3.1.5 to be equipped with brushless direct current (DC) motors. These motors are significantly more efficient than traditional permanent split capacitor (PSC) motors, offering better airflow control and reduced electricity usage.
Kitchen, Laundry, and Water Efficiency
Flexible Energy Supply for Appliances
Section 12.3.1.6 requires that every kitchen and laundry space must be prepared for various energy needs. To ensure future-proofing, these spaces must be provided with an electrical outlet, a natural gas line, or a propane line. This provides homeowners in the London area the flexibility to switch between electric and gas appliances easily.
Commitment to Water Conservation
Water efficiency is a core component of the 2024 Building Code Compendium. Section 12.4.1.1 specifies that all buildings must strictly conform to the water efficiency requirements of Subsection 7.6.4, focusing on plumbing fixtures and systems designed to minimize water waste in residential and commercial settings.
