Energy Efficiency Values

* U = U-value (W/m2 - K) - The lower the number, the more energy efficient the product.

* SHGC = Solor Heat Gain Coefficient - The higher the number, the higher the solar gain.

* ER = Energy Rating (W/m2 or dimensionless) - The higher the number, the more energy efficient the product.

* The ER (Energy Rating) format was changed to all positive numbers (dimensionless) in October 2004 by CSA (Canadian Standards Association) to address consumer confusion over negative numbers. The older format had a mixture of negative and positive numbers (W/m2).
