Energy Conservation
HEATING SYSTEMS
Using efficient heating systems saves money and energy. High efficiency furnaces have an annual fuel utilization efficiency (AFUE) rating of 90% or higher as opposed to the minimum standard of 78% efficiency. For heat pumps, a heating season performance factor (HSPF) rating of 7.5 or better is considered high efficiency.
When buying an electric water heater, look for energy-efficient models with an energy factor (EF ) rating of at least 0.96. Tankless on-demand water heaters, which use less energy than standard models, are also available.
If you have an older model water heater, consider getting a insulating blanket/jacket for it, which can pay for itself in energy savings in one year.
The United States Environmental Protection Agency (EPA) puts Energy Star symbols on energy-saving products. EPA’s website (www.energystar.gov) rates appliances, furnaces, air conditioners, and other energy-using products.
WINDOWS AND DOORS
Only 20% of homes built before 1980 are well-insulated. Insulating your home saves money on fuel and helps make you more comfortable indoors in winter and summer. To get the greatest benefit from your insulating project, prioritize your insulating needs by first addressing the areas that cause the greatest loss of heat.
Windows and doors are often a key area of concern. Many old windows lose heat through cracks around the sash. Old windows with single-sheet glazing lose a great deal of heat through conduction.
Similarly, a door that is not weather-tight can be a significant source of heat loss. What can a homeowner do?
Cracks around the stationary parts of windows can be caulked with a flexible caulk. Double-hung and sliding windows may need weatherstripping around jambs, sills, and meeting rails. Replacing old single-pane windows with energy-efficient models can save money on your heating bills. Installing insulating window shades on drafty windows will help save heating costs.
A good way to insulate your door is to use quality weatherstripping which contains insulation encased in a rigid vinyl, wood or aluminum strip. A door sweep can be attached on the inside of a door so that it fits snugly to the threshold when the door is closed. You will appreciate the loss of that terrible draft when the thermometer hits ten degrees!
APPLIANCES
If you are thinking about getting a dishwasher, consider this: a dishwasher actually uses less water than washing dishes by hand. Look for efficient dishwashers which have lower levels of water
usage. Most models use between 8 and 14 gallons of water for each load.
Front-loading washing machines use 30-60% less water and 50-70% less energy than top-loading models.
Plug home electronics into power strips and turn the power strips off when the equipment is not being used. TVs, computers and DVDs in standby mode still use a significant amount of electricity.
A refrigerator with automatic moisture control saves energy. Do not keep your refrigerator or freezer too cold. Temperatures of 37 to 40 degrees F. are recommended for fresh food areas; zero degrees
F. for freezers.
