BC Housing: 2013 Review Of Window Energy Rating Procedure In Canada BC Housing study Review of Window Energy Rating Procedure in Canada seeks to determine if the Energy Rating (ER) in its current form is still appropriate for selecting energy efficient windows and doors for all areas within Canada. It found that the current ER formula works in most common house situations, in most locations, and therefore it is an appropriate metric for rating the relative energy performance of windows. (PDF)

FES BC: Canadian Windows May Meet Passive House Window Requirements Fenestration Educational Society of BC is providing Canadian window manufacturers with tools to derive Passive House window data from their existing NFRC-based simulation data. They say many Passive House projects could use high performance Canadian-made windows if they have the window performance data required by the Passive House Planning Package software.

NRCan: New Canadian Specifications For Energy Star Windows Natural Resources Canada says effective February 1, 2015 all ENERGY STAR windows must meet specific energy efficiency levels that have been set for three climate zones in Canada. In addition, all products must be certified for their energy efficiency by an accredited agency. The three climate zones were developed by using heating degree-days, a measure of annual average temperature. Products are rated on either their U-factor or their Energy Rating (ER). The U-factor is a measure of the rate of heat loss. The lower the number, the slower the heat loss. The ER is a formula that includes the U-factor, air leakage and the benefit of potential solar gain. The higher the value, the higher the potential annual energy savings. Products must also have an air leakage rate of .1.5 litres per second per square metre of product area. (PDF)

IRC: New Harmonized Window Standard to Be Referenced In 2010 Canadian Building Code Canadian Institute for Research in Construction says a new, harmonized performance standard for windows, doors and skylights has been developed and will be referenced in the 2010 National Building Code of Canada (NBC), replacing a number of Canadian standards, some of which were outdated. The standard is AAMA/WDMA/CSA 101/I.S.2/A440, NAFS, North American Fenestration Standard/Specification for Windows, Doors, and Skylights.

RDH: NAFS & Water Testing of US Products RDH Building Science says there are several important differences between Canadian code requirements for window, door, and skylight products and the NAFS standard. One of these differences is how water penetration test failure is defined, and this can affect products tested to NAFS in the United States.

RDH: NAFS In Part 5 Of The Canadian Code RDH Building Engineering says we are using NAFS, the North American Fenestration Standard, only because it is in the National Building Code. So what, exactly, does the Code tell us about the use of NAFS in Part 5, and does this have implications for NAFS compliance in Part 9?
