Changes to Ontario Building Code Affect Energy Performance Requirements

March 15th, 2012 by Editor

Certain changes to the 2006 Ontario Building Code (OBC), which was updated on January 1, 2012, will impact fenestration companies working and selling in Canada. These changes introduced the Supplementary Standard SB-12 which changed the energy performance requirements for Part 9 buildings in the 2006 OBC. SB-12 introduced three possible methods of proving compliance with the energy performance requirement of the 2006 OBC. The three methods include:

• Prescriptive Compliance Packages (Subsection 2.1.1);

• Performance Compliance (Subsection 2.1.2), and

• Other Acceptable Compliance Methods (Subsection 2.1.3).

According to Fenestration Canada (FC), these changes represent a significant change to the OBC and the guide is meant to help clarify the changes for fenestration performance.

FC’s Technical, Education and Government Relations Committees have worked together to create a training presentation designed to provide unbiased information to educate building code officials and related groups on specification issues related to fenestration products. The presentation has three sections, the first of which covers the National Building Code 2010.

Included in this component is an overview of the code sections concerning doors, windows and skylights, reference to NAFS in the 2010 NBC and what is covered under the NBC.

Section two explains what NAFS is, how it is different from CSA, what the new performance ratings are, an explanation of the Canadian supplement to NAFS and what the new labeling requirements are.

A third section discusses how the performance requirements for fenestration products are determined, including determining DP, determining water and Canadian resistance requirements.

According to FC, the presentation will soon be made available for use and reference by members on its website.
