What is a good energy rating for a window

The higher the ER, the more energy efficient the window. Good performing windows and doors have an ER of 29 or higher.

Is .27 a good U-factor for windows

While the U-Factor can take any value, in general for windows it ranges from 0.20 to 1.20. The lower the U-Factor, the better the window insulates.

Is .30 a good U-factor for windows

The best, high-performance, double-pane windows may have a U-factor of 0.30 or lower, indicating that they are very energy-efficient. Some triple-pane windows may have a U-factor as low as 0.15.
