ENERGY STAR High Efficiency Haute Efficacité

Windows (Select a New Product)

Windows and doors are eligible for ENERGY STAR® based on their U-factor that measures their overall heat loss, or, their Energy Rating (ER) that combines their passive solar heat gain (SHGC) through the glass with their overall heat loss and air leakage. Models must have a U-factor of 1.22 W/m2 or lower, or, an ER of 34 or higher.

To find models that are the most efficient, select the ENERGY STAR Most Efficient checkbox in the “Energy Efficiency Criteria” section below. Models must have a U-factor of 1.05 W/m2 or lower, or, an ER of 40 or higher.

Caution is advised when selecting windows and sliding glass doors with passive solar heat gain (SHGC) values above 0.45 that will face south or west, especially if there is more glass area than exterior wall area (high window to wall ratio), as this could cause uncomfortably warm room temperatures and higher cooling costs.

Seeking advice from a qualified Energy Advisor can help ensure that you choose the right windows and doors to lower your energy bills and have optimal thermal comfort in all seasons.
