ENERGY STAR® – Canada Products may comply for Canada’s Energy Star program based on these compliance paths: their total U-factor, their Energy Rating (ER), or both. The Energy Rating is based on a product’s overall performance based on three criteria: (1) solar heat gain,

(2) U-factor, and (3) average air tightness. The higher the ERnumber, thebetter theproduct’s thermal performance. The U-factor and ER criteria for Canada’s three climate zones is shown in the charts provided.

} Solar Heat Gain Coefficient (SHGC) is a measure of how much solar energy is passing through the unit’s glass. The lower a window or door unit’s SHGC, the less solar heat is transmitted into a room, thus allowing for lower cooling bills in hot climates. } Visible Transmittance (VT) is a measure of the portion of visible light that passes through a window or door. The higher a window or door unit’s VT Total, the more visible light is transmitted into a room. This value is influenced by both the glass selection and by the ratio of glazing and frame area.
Energy Performance Terminology } U-Factor refers to a measure of heat transfer through the window or door unit. A lower U-factor means less heat escapes during winter weather, thus reducing heating costs in cold climates. } R-Value refers to resistance to heat flow. A high R-value indicates that a window or door has good heat insulating properties.
