New Building Code Requirements in Ontario Set to Enhance Energy Efficiency and Occupancy Standards

📅 6 days ago 🏷️ Ontario General Contractors Association

Ontario's new Building Code requirements, effective January 1, 2012, focus on improved energy efficiency standards for both residential and commercial buildings, alongside new regulations for occupancy permits.

Starting January 1, 2012, new requirements under Ontario’s Building Code will come into effect, specifically targeting energy efficiency and occupancy permits for new constructions. These updates mark a significant step forward in the province’s ongoing commitment to enhancing building standards, particularly regarding energy conservation.
The changes in energy efficiency requirements apply to any building permit applications submitted on or after the effective date. The 2006 Ontario Building Code laid out a comprehensive framework for energy efficiency that was to be progressively implemented until the end of 2011. This framework included specific benchmarks for both residential homes and larger buildings. Following the roadmap established, the updated requirements will ensure that new constructions adhere to stricter energy efficiency standards.
For residential buildings, particularly those classified as Part 9 structures that are intended for year-round occupancy during winter months, the new regulations stipulate a performance level that must achieve a rating of 80 or higher when assessed using the EnerGuide80 rating system. This system is based on the Hot 2000 V9.34c1 software. Builders can also choose to conform to Supplementary Standard SB-12, which outlines alternative compliance methods that were introduced in an amendment to the Building Code effective January 1, 2010.
In contrast, other building types, including Part 3 residential and commercial structures, will be required to meet the standards set out in Supplementary Standard SB-10, which was updated on July 1, 2011. This standard mandates that the energy efficiency of these buildings must exceed the benchmarks established by the 1997 Model National Energy Code for Buildings by at least 25%. Similar to SB-12, SB-10 provides multiple compliance pathways to help builders meet these new requirements.
To facilitate compliance with these updated standards, stakeholders and builders are encouraged to engage in technical training courses that cover the energy efficiency aspects of the Building Code. The Ministry of Municipal Affairs and Housing (MMAH) has partnered with organizations such as the Ontario Building Officials Association and various community colleges to offer these training sessions. Builders can also seek assistance from the Ontario Home Builders Association to learn more about available training opportunities.
In addition to energy efficiency regulations, the new Building Code amendments will also implement changes to occupancy permits for certain new residential buildings. Effective January 1, 2012, any new residential building permit application must undergo an inspection and acquire an occupancy permit before individuals can occupy the space. This requirement will apply to structures that are three stories or fewer in height and have a total building area not exceeding 600 square meters. Specific conditions must also be met, such as no tourist accommodations, no dwelling units situated above another, and no shared means of egress between dwelling units.
These new occupancy permit criteria will not affect existing buildings or portions of buildings undergoing renovations, including extensions or significant alterations. For detailed information, refer to Section C 1.3.3.1 of the 2006 edition of the Building Code, as amended by Ontario Regulation 503/9.
As the development of the next edition of the Building Code progresses, it is important to note that these energy efficiency and occupancy permit requirements will remain in effect as outlined, regardless of the timeline for the upcoming edition.
