Some of my favorites parts of this are the calculators for appliances and windows. It gives some pretty quick and easy data on operating costs of say your current model vs. operating costs to purchase a newer one with your projected annual savings. That obviously makes pay back a much easier thing to calculate.
It looks at everything from ceiling fans to insulation and sealing. Granted, I can get pretty geeky about building technology, but this is a really cool tool to pass along in a newsletter or on your website and blogs. Check out the Energy Open House now.
