How does ENERGY STAR measure its criteria?
By measuring four different parts of the window: the glass, the gas, the spacer and the reinforcement. The combination of these factors influences the unit’s U-value and solar heat gain, both of which are drivers for meeting ENERGY STAR performance level. By adjusting any one or more of these four factors allows us to meet the new ENERGY STAR criteria.
To be labeled as an ENERGY STAR product, the U-factor and SHGC (Solar Heat Gain Coefficient) ratings must be less than or equal to those established by ENERGY STAR.
- U-value The U-value or U-factor is commonly described as the amount of heat transferred through a material. The lower the U-factor, the slower the rate of heat flow and the better the insulating value.
- Solar Heat Gain Coefficient (SHGC) The SHGC refers to the amount of heat from the sun that windows and doors allow into the home. The lower the number, the greater the ability to reduce the amount of heat absorbed into the home.
