Extra Energy Tips

Insulation

1.Make sure your home is properly insulated. This is the single most important step in conserving energy. Thermal insulation should be specified in terms of thermal resistance (R-values). R-30 (10") is recommended for ceilings, R-11 (3-1/2) for exterior walls and floors over unheated areas. In colder climates, consider additional insulation.

2.Infiltration of humid outside air is your heating and cooling system’s worst enemy — it could account for 15 to 30% of air conditioning energy requirements. Find the places where air can sneak into the home and plug them with caulking, weather- stripping or plastic. Also, weather- strip and caulk around all entrance doors and windows.

3.Cut heat transfer through your windows by 40 to 50% with double glazing (two panes of glass sepa- rated by a sealed air space) and low-e glass.

4.Use wood- or metal-frame storm windows even if single-glazed windows are high quality. The extra layer of glass and the layer

of still air will cut heat transfer considerably.

5.Install storm doors at all entrances to your house.

6.Keep all windows and doors closed.

7.Remember that by increasing the glass area, you increase the amount of heat added in summer and lost in winter.

8.Make sure fireplaces have tight- fitting dampers which can be closed when the fireplace is not in use.

9.Invest in a humidifier to conserve energy in winter. The air in your home won’t be as dry, so you stay comfortable at a lower temperature setting.

Heating

10.Locate the thermostat on an inside wall away from windows and doors.

11.Set the thermostat as low as comfort permits. Each degree over 68°F can add 3% to the amount of energy needed for heating.

12.People generate heat. So lower the thermostat a degree or two when expecting a large group of guests.

Cooling

13.Set the thermostat as high as comfort will permit.

14.Make sure attics are adequately ventilated to relieve heat buildup. If necessary, improve airflow by adding or enlarging vents.

15.When building a new house or renovating an old one, choose light-colored roof shingles to reflect more of the sun’s heat.

16.During moderate weather, don’t use the air conditioner unnecessarily.

17.Draw blinds or drapes to block the sunlight during the hottest part of the day.

18.Install awnings over windows exposed to direct sunlight.

19.In the cooling season, don’t run kitchen and bath exhaust fans longer than necessary.

20.Don’t place lamps, TV sets or other heat producing devices beneath a wall-mounted thermostat. Rising heat from the equipment may cause the heat pump to over cool your house.
