2) Window Replacement: typically replacing windows can save up to 2-3 therms/year per window. This results in a savings of $2-$3 per year per window. Certainly replacing very old windows with storm windows can save more- but generally windows that are the most efficient are also the most costly. Saving big money by replacing windows is probably the biggest energy savings misconception period.
3) Furnace Tune- Ups: Annual safety check-ups are important, but typically tune-ups are only needed every 4-5 years.
4) Caulking and Weather-stripping: Mr.Blasnik cited a Canadian Study that concluded that caulking around leaky windows can typically save about .5 therms/year- the equivalent of 50 cents.
5) Changing Furnace Filters: According to Mr. Blasnik, once every season is enough-changing those monthly doesn’t save anything.
6) Cooling your attic- You won’t save much by insulating from the rafters- unless you have AC duct work in the attic. If that is the case- you can save up to 15% by insulating from the rafters.
7) Using Drapes to insulate windows- doesn’t work and can actually create convective loops in the space between the windows and drapes.
8) Energy Saving Kits- 2 CFL’s are not going to make your bills lower.
