You can create an imporved envelope of insulation around your home by building with materials to reduce drafts and by sealing cracks and gaps that permit air and moisture exchanges. This could reduce your heating and cooling costs by about 2,250 kilowatt-hours of energy and $180 per year. If every new home were built with a tightly insulated envelope, the energy savings would equate to more than doubling the fuel efficiency of the 210,000 postal vehicles that deliver the US mail.
