Ontario Announces Fenestration Energy Performance Requirement

January 8th, 2013 by DWM Magazine

Fenestration Canada is working to educate the industry regarding an update to The Ontario Green Energy Act which has been in place since 2009. The Act has been updated to include energy efficiency requirements for windows–doors and skylight are not included at this time. The change takes effect January 1, 2013, but the requirements for windows will not take effect until January 1, 2014, according to the association.

The following are some requirements of the program that apply to residential windows only. For basement windows that incorporate a load-bearing structural frame, the window must be double-glazed with a low-E coating. For all other windows, U-factor ≤ 2.0 W/(m²C) or an energy rating ≥ 17. The windows must be certified and labeled to CSA A440.2 or NFRC (thermal certification only).

Excluded products include: decorative windows that have stained glass panels, iron inserts or blinds contained in a sealed insulating glass unit; heritage replacement windows intended to be installed in a heritage building; glazing replacements in an existing sash or frame, if the U-factor of the replacement glazing is equal to or less than the U-factor of the original glazing; decorative sidelights for doors; windows that are designed for a specific building; and windows that fall outside the scope of the certification programs for CSA or NFRC.

“These requirements are not as strict as the building code requirement, but it does mean that all windows sold in Ontario will have to be certified to CSA A440.2 or NFRC,” according to the association’s announcement. Fenestration Canada says it will follow-up with more information on the Ontario Green Energy Act requirements early in 2013.
