2012 Building Code Requirements for New Construction

New Building Code requirements come into effect on January 1, 2012.  These relate to energy efficiency and occupancy permits.

 

Energy Efficiency

If you apply for a building permit on or after January 1, 2012, the proposed construction must conform with enhanced energy efficiency requirements of Ontario's Building Code.

 

The 2006 Ontario Building Code set out a "roadmap" for energy efficiency to be implemented from January 1, 2006 through to December 31, 2011.  As part of that roadmap, the Code set out energy efficiency benchmarks for houses and for large buildings.  Subsequent Code amendments provided additional compliance paths that are consistent with those benchmarks. 

 

The Building Code provides that construction for which an application for a building permit is made on or after January 1, 2012 must meet the following energy efficiency requirements:

 

o        Houses and other Part 9 residential buildings intended for occupancy on a continuing basis during the winter months must meet the performance level that is equal to a rating of 80 or more when evaluated in accordance with EnerGuide80[1] (based on the Hot 2000 V9.34c1,2 software) or conform to  Supplementary Standard SB-12, which is referenced in the Building Code.  The alternative compliance paths set out in this Supplementary Standard are referenced in an amendment to the Building Code which came into force on January 1, 2010.  For more information about the updated Supplementary Standard SB-12 follow the link to Service Ontario's publications site at http://www.publications.serviceontario.ca/ecomlinks/510090.pdf.

 

o        Other buildings (including Part 3 residential and commercial buildings) must conform to Supplementary Standard SB-10 (July 1, 2011 update), which is referenced in the Building Code.  This Supplementary Standard indicates that the energy efficiency of these buildings shall be at least 25% greater than the energy efficiency levels attained by conforming to the 1997 Model National Energy Code for Buildings, but provides additional compliance paths to achieve them.  The updated Supplementary Standard SB-10 is referenced in an amendment to the Building Code which came into force on July 1, 2011.  For more information about the updated Supplementary Standard SB-10 follow the link to the Ministry of Municipal Affairs and Housing's Building Code website at http://www.mah.gov.on.ca/Page9528.aspx
