Ontario Supplementary Standard SB-12 2011 (amended 2016)

Last updated: 13 June 2019

This Supplementary Standard includes design options regarding the energy efficiency of a building or part of a building of residential occupancy that is intended for occupancy on a continuing basis during the winter months.

The first edition of this Supplementary Standard was published in 2009. The energy efficiency levels achieved in that edition were intended to meet or exceed, on a systematic basis, the EnerGuide 80 level of energy efficiency that would be met by model analogues evaluated against the NRCan “EnerGuide for New Houses: Administrative and Technical Procedures” (2005). The editions published in 2012 and 2013 included certain trade-off options in recognition of the Energy Star program that expanded the number of building component and assembly permutations considered to represent acceptable solutions. The September 2013 also included a new “Chapter 3” with compliance packages that demonstrated how to achieve an additional energy efficiency level increase of 15% over the requirements that took effect on January 1, 2012.

The 2016 update of the Supplementary Standard is primarily intended to update the compliance packages set out in Chapter 3. Changes include the identification of credits based on airtightness. The compliance packages and options described in Chapter 3 are applicable to building permits applied for after December 31, 2016. Other changes include the recognition of the technical requirements of Energy Star and R2000 programs as design options for meeting the energy efficiency requirements of the Building Code.

Labelling is not required to demonstrate compliance with this Supplementary Standard.
