As of January 1st, 2012, any proposed building construction in Ontario that falls outside the scope of Part 9 buildings (i.e. all buildings except low-rise residential) must comply with the new energy efficiency design requirements of Supplementary Standard SB-10.
These requirements can be met through prescriptive or performance-based approaches. The prescriptive path requires a window-to-wall ratio of no more than 40%, and thus may not be an option for many modern window-wall or curtain-wall facade constructions. The performance path requires a whole building energy model to demonstrate equivalent energy performance using approved modeling software.
The following 4 paths are available:
- (Performance) Exceed by at least 25% the energy efficiency performance of the Model National Energy Code for Buildings (MNECB) 1997;
- (Performance) Exceed by at least 5% the energy efficiency performance of ASHRAE 90.1-2010, “Energy Standard for Buildings Except Low-Rise Residential Building”;
- (Performance or Prescriptive) Achieve the energy efficiency levels of ASHRAE 90.1-2010, “Energy Standard for Buildings Except Low-Rise Residential Building” and Chapter 2 of Division 3 within SB-10; or
- (Performance or Prescriptive) Achieve the energy efficiency levels of the National Energy Code for Buildings (NECB) 2011, and Chapter 2 of Division 3 within SB-10.
