ENERGY STAR® PROGRAM CHANGES COMING UP IN 2020
Oct,02, 2019
Window City is one of the largest manufacturer in Canada to become one of the 1st partner with the Energy Star® program in Canada. We are proud to announce that most of our products are CSA certified. We use a patented raw material mix which allows for a stronger, longer lasting and more energy efficient vinyl windows. Since 1992, we have been known for excellence, innovative design, superb craftsmanship, state-of-the-art technology and reliable delivery.
Government of Canada has introduced a new standard for ENERGY STAR® program in April 2019. These changes will come into effect on January 1, 2020. This includes the updates to windows, doors and skylight standards for Canadian manufacturers, installers and home builders. In this blog we will discuss the upcoming changes in 2020 to the Energy Star program in Canada.
The performance of the ENERGY STAR® certified residential products sold in Canada must meet specific U-value, Energy rating and air-tight efficiency specifications to be in effect from January 1, 2020.
U-Factor: The rate of heat loss of a window or door. A formula measures the heat transfer per time per area and per degree of temperature. The lower the U-Factor the better insulating properties.
Solar heat gain coefficient (SHGC): The ratio of the solar heat gain entering the space through the fenestration product to the incident solar radiation.
Air leakage: The amount of air flow that passes through windows and doors.
Energy Rating (ER): ER is a formula that balances heat loss (U-Factor), air leakage and potential passive solar gain.
The Simplified ER equation is as follows:
ER = (57.76 × SHGCw) – (21.90 × Uw) – (1.97 × L75) + 40
Where,
• SHGCw = fenestration system solar heat gain coefficient
• Uw = fenestration system U-factor (W/m2)
• L75 = fenestration system air leakage rate at a pressure difference of 75 Pa, established in accordance with AAMA/WDMA/CSA 101/I.S.2/A440 (North American Fenestration Standard) in L/s•m2. The L75 shall be the average of the infiltration and exfiltration measurements.
A complete explanation of the ER equation may be found in the CSA A440.2 Standard.
As of January 1, 2020, residential windows and doors must meet or exceed the following thresholds to be deemed as ENERGY STAR® certified product in Canada.
