10 Energy-Saving Tips That Require An Investment

• Seal heating and cooling ductwork. Duct leakage can be substantial--as much as 20% to 30%. Use water based mastic only.

• Buy EPA Energy Star labeled energy-efficient equipment. When buying or replacing office equipment, compare energy requirements of various models.

• Repaint building exterior with light colors. More sunlight will be reflected away from the building, thus lowering air-conditioning expenses. This is especially true for your roof.

• Replace old appliances with more efficient models. Replacing an old dishwasher, refrigerator, washing machine, or furnace -- with a new, energy-efficient model can really save energy and money. Look for the Energy Star label.

• Home Energy Audit. A home energy audit can identify ways to save up to hundreds of dollars a year on home heating and air conditioning.

• Increase attic insulation to R-30. Insulation helps keep heat out in the summer and the cold out in the winter.

• Insulate floors over unheated spaces to R-19. Insulation provides a thermal boundary, reducing energy use and increasing comfort.

• Insulate and seal ducts in attics, crawl spaces, garages and other unheated areas.

• Install Energy Star windows. These windows cost ~$0.50 /sq.ft. more than standard windows, save energy and increase comfort.

• Install a solar water heater. A solar water heater can provide 50% to 80% of your hot water needs.
