As of January 1, 2017, the submission requirements for all permit applications made for new Part 9 non-residential and Part 3 buildings and additions have changed. This provides staff with a greater opportunity to review and comment on the aspects of a building that affect energy consumption, helping to ensure that the minimum efficiency requirements of the Ontario Building Code are met through active enforcement.

Energy efficiency requirements

Part 12 and Ministry of Municipal Affairs (MMA) Supplementary Standard SB-10 of the 2012 Building Code outline the energy and water efficiency requirements for both Part 3 buildings and for Part 9 non-residential buildings.

New requirements in SB-10 came into effect on January 1, 2017 that will result in a 13% improvement over previous energy efficiency measures. The Ministry of Municipal Affairs has revised the options applicants can use to demonstrate compliance with the requirements of SB-10, as detailed in the December 22, 2016 version of SB-10.  Note that as of January 1, 2018, the previous version of SB-10, dated September 14, 2012, is no longer applicable and may not be used for demonstrating compliance.

The Energy Efficiency Design Summary (EEDS) forms outline the compliance options available to designers and list the documentation required to be submitted for each of the particular options. The following is a list of documentation that must be submitted regardless of selected compliance option:

  • Energy Efficiency Design Summary form (either Part 3 or Part 9 non-residential)
  • All documentation listed in the EEDS form specific to the selected compliance option
  • MMA Project Information Form
  • Air barrier section and detail drawings indicating continuity of the air barrier
  • Heat loss / heat gain calculations
  • Ventilation rate calculations, and
  • Lighting power density calculations

Depending on the selected compliance path, the following information may also be required:

  • Energy simulation output report
  • CO2e emission calculations
  • Peak electric demand calculations

Applications submitted after December 31, 2017

For permit applications made after December 31, 2017, use this flow diagram to determine which compliance option(s) are suitable for use with your project.

Once you have identified the compliance option, complete one of the following Energy Efficiency Design Summary (EEDS) forms:

The EEDS forms detail the additional documentation requirements for each compliance path. To help avoid delaying issuance of a building permit, please ensure that all required documentation is complete and submitted per the instructions below. See section on submission of documentation for full details.

Note that the Ministry of Municipal Affairs has revised the SB-10 checklist forms referenced in the above documents.  These forms are available for download at

Exempt buildings

Building types exempt from complying with Part 12 are listed in Sentence of the Building Code and exceptions specific to the Supplementary Standard SB-10 are listed in Article of Division 3 of SB-10. To assist designers, the following document provides a summary of these exemptions:

Submission of documentation

All of the above referenced documentation shall be submitted electronically directly to [email protected] at the time of permit application. Please note that building permits cannot be issued until all energy efficiency forms and documentation have been received and reviewed.
