 How To Compare Window Energy Performance

 Efficient Windows Collaborative (EWC)

Easy Scale: star rating ease of implementation [6]
(1-10 scale, 1 = Difficult and costly, 10 = simple and no cost or little effort)

Impact Scale: star rating impact of action [2]
(1-5 scale, 1 = Minor but worthwhile, 5 = Strong impact on environment)

To improve a window's energy efficiency the number of glass panes in the window unit is doubled, because multiple layers of glass increase the window's ability to resist heat flow.
