SmarterHouse, a project of the American Council for an Energy-Efficient Economy, is a complete and up-to-date guide available on energy savings in the home.
Following a review of measures to tighten up the building shell itself, the site focuses on the things you put in it your home—including major appliances, heating equipment, air conditioning, lighting, and electronics—and how the energy use of those products can be reduced.
If you’re about to buy a new appliance or heating system, you’ll be most interested in the tips on what to look for when buying new equipment. Otherwise, look for guidance on how to get the best energy performance through operation and maintenance of the products you already own.
For further information and updates, they’ve included links directing you to valuable resources provided by the government, trade associations, and other sources.
