A recent article in the Boston Globe about “buttoning up” your house for the winter includes a neat interactive graphic (click on the image of the house to see the graphic) where you can see the payback period for various weatherization techniques. The shortest payback period? Window plastic wrap, that clear plastic you can install on the inside of your windows in the fall and remove in the spring. The longest? Replacement windows – at 33 years (according to this article, anyway – other studies have found much longer payback periods, well longer than the expected life of the windows).
