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)
