Energy Efficiency Practices for the Low- Income Population Donald Fournier Managing Director SEDAC University of Illinois
Residential Energy American homes use almost 25% of the energy consumed in the United States. About 80% of that energy is used in single-family homes, 15% in multi-family homes (such as apartments and condos), and 5% in mobile homes. Residential energy use has steadily increased over the past 25 years, but has increased at a slower rate than the rate of population increase. Many efficiency gains are being offset by increases in the number of electronics and appliances in the average home. There are still many opportunities to reduce energy consumption in the home at low or no costs.
Residential Trends Electricity represents the biggest change in residential energy usage. Result of significant nationwide increase in home central air conditioning, use of home energy appliances, and computers Electricity remains the most expensive energy source
Residential Energy Consumption Heating will be the largest energy usage. Next will be appliances and lighting. Next is water heating, then cooling.
No Cost Ways to Save In winter turn down your thermostat to 68 degrees: Every 1% setback = 3% savings on heating bill. Wear warm clothing to stay comfortable. Set the thermostat back to 55 degrees when away or sleeping (save 5-20%). In summer with central cooling, turn up your thermostat to 78 degrees: Dress appropriately. Set up during the day if no one home. Turn off window units when not in the room.
Low Cost Ways to Save Replace or clean furnace filters every one to three months. Dirty filters restrict airflow and increase energy use. Keeping your furnace clean, lubricated and properly adjusted will reduce energy use, saving up to 5 percent of heating costs. In summer, keep central A/C condenser clear of leaves, bushes, etc. Use a ceiling fan and turn up the thermostat a few degrees. Do not simply remove dirty filters. This will allow dirt to collect on the heat exchanger surfaces and reduce efficiency.
No Cost Ways to Save Reduce hot water temperature to º. Save 7-11 % of water heating costs. Insulate water supply line (first 5 feet). Use cold water when washing clothes % of home energy cost is for water heating (todays detergents are designed for cold water). Clothes dryer: Keep dryer free of lint (clean filter every load). Keep dryer vent free of obstructions. Do not vent into the house or attic.
No Cost Ways to Save Perform a Do-it-Yourself Home Energy Audit at
No Cost Ways to Save Take a 5 minute shower instead of a bath. In heating season let the sun in. Open drapes and shades on the sunny side during the day. Close at night. Remove window air conditioning units for the winter. Remove to prevent heat from escaping through and around the unit. If it cannot be removed, buy a cover to prevent drafts (or wrap and tape with a large piece of plastic).
No Cost Ways to Save Close your fireplace flue. Keep closed except when not in use. Also shut fire place doors if installed. Use your ceiling fan. Run blades counter-clockwise in summer to push to create a breeze (moving air feels cooler). Set up thermostat a few degrees. Run clockwise in the winter to bring warm air down (only if there are high ceilings). When purchasing new ceiling fans, consider an ENERGY STAR model
No Cost Ways to Save Put your computer to sleep. Activate "sleep" when not in use for a while. Turn off equipment during longer periods of non-use to cut energy costs and improve longevity. Dont waste hot water. Adjust load size on washer to fit actual load.
No Cost Ways to Save Flip the switch. Turn off appliances when not in use: lights, TVs, VCRs or DVDs, computers, other electronics. Unplug electronics with remotes when not being used regularly. Keep vent space clean & clear. Make sure draperies, furniture or rugs arent blocking air. Clean grills regularly with a vacuum or a broom.
No Cost Ways to Save Clean Refrigerator Coils Condenser coils are located in the back of older refrigerators and at the bottom of most new ones. They should be periodically cleaned with a vacuum or brush. Be sure to unplug the refrigerator when cleaning the coils.
Low Cost Ways to Save Caulk is cheap. Seal around windows, doors, and exterior walls near the floor, electrical outlets and plumbing penetrations. (Save % on heating.)
Where to look for air leaks.
Home Sealing Caulk is cheap. On windy days, feel around windows, doors, and exterior walls near the floor, electrical outlets or plumbing penetrations. Seal up your windows and doors with caulking and weather stripping to ensure that you're not wasting energy on heat that escapes through leaks to the outdoors. Caulk works best on small gaps. Your hardware store should have products to close the larger gaps. Use low expansion foam product to seal larger openings. Source: EPA - A DO-IT-YOURSELF GUIDE TO ENERGY STAR® HOME SEALING
Seal Small Gaps Use expanding foam and caulk to seal the openings around plumbing vent pipes and electrical wires. Be sure to wear gloves and be careful not to get expanding foam on your clothes, as the foam is very sticky and nearly impossible to remove once it sets. When the foam or caulk is dry, cover the area again with insulation.
Seal and Insulate Attic Hatches
Low Cost Ways to Save
Install Window Kits in Winter Use when there are single pane or lose fit windows. Cuts out infiltration and adds to thermal barrier. Shrinks tight for a transparent, wrinkle-free fit. Double-sided tape seals off cracks and crevices. Quick & easy installation. Kits available for a variety of window sizes.
Low Cost Ways to Save Check the yellow energy label on your water heater. A low efficiency water heater could use an insulation blanket.
Low Cost Ways to Save Insulate Water Heater & Pipes
Low Cost Ways to Save Seal leaks with mastic or aluminum tape Insulation Tape seams Seal and Insulate Ducts
Low Cost Ways to Save Go low flow. Install low- flow showerheads and sink aerators. Repair leaky faucets and toilets promptly – save water, money, and energy.
Low Cost Ways to Save Install an ENERGY STAR programmable thermostat: Temperature automatically sets back when asleep or away. Consider ENERGY STAR labeled appliances - use less energy, save money, and help the environment. Change a Light. Replace incandescent light bulbs with comparable compact fluorescent lamps.
Compact Fluorescent Lamps CFLs use far less energy. Have comparable brightness and color rendition compared to incandescent lamps. Can directly replace standard incandescent bulbs. IncandescentCFL 25 Watt=5 Watt 50 Watt=9 Watt 60 Watt=15 Watt 75 Watt=20 Watt 100 Watt=25 Watt 120 Watt=28 Watt 150 Watt=39 Watt
Comprehensive Ways to Save Check your insulation: Check attic, ceilings, exterior and basement walls, floors, and crawl spaces vs. insulation levels recommended for your area. R-valuesthe higher the R-value, the better your house will resist the transfer of heat. DOE recommends ranges of R-values based on local energy costs and climate conditions. See Zip Code Insulation Calculator, for economic insulation levels: Code Insulation Calculator
Comprehensive Ways to Save Increase your attic insulation. Easiest and most cost- effective insulation option. If less than R-19 (6 inches of fiber glass or rock wool or 5 inches of cellulose), more could help. Consider insulating exterior walls. If attic insulated but home still drafty and cold in the winter, or too warm in the summer, add insulation to the exterior walls.

Comprehensive Ways to Save Keep your furnace operating efficiently: Seasonal Inspection. Heating and cooling = half of the energy costs for the average home. Ask for temperature-rise check to be sure your furnace is operating in the range set by the manufacturer.
Comprehensive Ways to Save Look for the ENERGY STAR: Consider replacing old gas appliances with ENERGY STAR® models.ENERGY STAR If gas water heater > 12 years, consider replacement. Look for the Energy Factor (EF)- the higher, the more efficient. If furnace > 15 years, consider an ENERGY STAR rated model - about 15 % more efficient vs. standard.
Should You Replace Your Furnace? If furnace >10 years and repair costs > $500, replace rather than repair. If your furnace is old but not broken, deciding when to replace it can be difficult: Average life of furnaces: years. Boilers life: 30 years. Start shopping before life is over, so you wont make a hasty decision.
Replacing your furnace? Emergency shopping can be costly. If house is large with high heating bills, may be cost-effective to purchase a high efficiency model now. If repairing furnace, look for a heating professional who has experience with your type of heating system. Take advantage of tax credits and utility incentives.
95% AFUE 1 Furnace w/ Electrically Commutated Motor (ECM) High efficiency furnaces, but poor electrical efficiency. Air handlers can draw over 700 watts. Efficient air handlers draw between 200 and 400 watts. 40% to 70% more efficient than standard furnaces. 1 – Annual Fuel Utilization Efficiency
When Buying New Appliances Check the EnergyGuide label. Estimated yearly energy consumption and cost. Your actual energy consumption and cost will vary. Scale for comparison with other models. Shop around and find an Energy Star model for the same price as a standard model.
Tax Incentives Energy Policy Act of 2005 with many follow-on changes has energy efficiency incentives for existing homes. Average home loses % of its energy through inadequate insulation and inefficient lights and appliances. Energy bill offers consumers tax credits for making energy efficiency improvements in homes. For 2011: cost-based credit to for energy improvements (limit $500): 10% up to $200 for Energy Star doors & windows. 10% up to $500 for insulation, duct sealing, and infiltration reduction. 30% up to $150 for furnace or hot water boiler. 30% up to $300 for any energy-efficient heat pumps, central air conditioners, and water heaters.
