Ontario’s Ministry of Municipal Affairs Seeks Industry Feedback on Updates to the Ontario Building Code 

 

Ontario’s Ministry of Municipal Affairs (MMA) has announced that the Ontario Building Code (OBC) is being updated. There are 3 phases that come into effect in January 2019, January 2020 and January 2022. MMA is currently seeking comments on the proposed changes. The summary and description on the proposed code changes can be viewed at Ontario’s MMA website.

 

Members are encouraged to review the links below and in addition to visit Ontario’s MMA website to look at other proposed technical changes to Ontario’s Building Code.

 

The public consultation period ends on September 29, 2017. Members are encouraged to submit comments to either Robert Waters or Kevin Wong by September 20, 2017. CIPH will work together with HRAI to submit comments on behalf of the industry.

 

Here is a summary of the proposed code change proposals: 

 

  • New beefed-up requirements for the building envelope and improved energy efficiency which include:
  1. Continuous insulation in all wall assemblies
  2. Triple-pane for all windows and sliding doors
  3. Air leakage testing mandatory in 2020, and in 2022 reaching a certain level will allow for credits
  4. Further limitations to building envelope vs mechanical trade-offs 
  5. Eliminating building envelope trade-offs
  6. Enhanced mechanical equipment efficiency
  • Drain water heat recovery will be mandatory in all buildings
  • Updated provision for grey water reuse
  • Solar ready roofs and pipe chases will be mandatory
  • Updated water conservation requirements with low flow fixtures and urinals
  • Backwater valve requirements for all new homes connected to municipal sewers
  • Electric vehicle charging requirements for multi-family residences
  • Requirements to improve the energy efficiency of buildings undergoing renovations

 

It is also important to note that the consultation paper addresses proposed updates to energy-related supplementary standards SB-12 and SB-10 referenced in Ontario’s Building Code. In particular, the consultation paper includes draft copies of proposed SB-12B and SB-10B supplementary standards which will apply to construction of buildings effective January 2022 (based on the date of permit application). Of specific interest to water heater and boiler manufacturers are the minimum energy efficiency requirements specified for space heating and water heating equipment. The number of compliance packages has been reduced to three, however, there is still one prescriptive package that requires a 96% space heating appliance efficiency, which will still be of concern to water heater and boiler manufacturers. The SB-12B and SB-10B drafts are linked below in this e-mail.

 

Members may also choose to submit individual comments directly to Ontario’s Ministry of Municipal Affairs.

 

Please pass this on to anyone in your company who would value this information.
