Whether for environmental or monetary reasons, everyone wants to save energy in their home. We’re exploring some simple ways to make your home more energy efficient from heating and cooling to insulation and lighting.

Heating & Cooling

To reduce the energy used for heating and cooling your home:

  • Close curtains in the summer to keep out heat, and open curtains during in day in the winter to let in sunlight.
  • Run paddle ceiling fans counterclockwise in the summer for cooling when the room is occupied, and clockwise on low in the winter to circulate the warm air near the ceiling.
  • Change the air filter on your heating and cooling system (HVAC) regularly to allow it to run more efficiently.

  • Check the ductwork on your HVAC system for air leaks, and fix any that you find.
  • Keep shrubs cut back around your outside HVAC unit, and use a garden hose to rinse it off from time to time.
  • Install a programmable thermostat to turn the heat or air conditioning up or down when you’re not home.
  • When buying a new air conditioning unit for your home, choose one with a high SEER (Seasonal Energy Efficiency Ratio) rating, so it will be more energy efficient.

Attic Insulation

To reduce heating and cooling costs, make sure you have plenty of attic insulation. The effectiveness of insulation is expressed by the R-value:

  • Attics in warm climates should have at least an R-38, or about 12” of fiberglass insulation.
  • Houses in colder climates need a minimum of an R-49, or approximately 16” of insulation.

When adding additional insulation to your attic, use unfaced insulation, and wear:

  • Goggles for eye protection
  • An approved dust mask or respirator
  • Long pants and long sleeved shirt
  • Protective gloves
  • Apply baby powder to exposed skin to reduce irritation

To insulate an attic stair opening, build a foam box in the attic around the opening, or install a premade cover like the Owens Corning Attic Stair Insulator, available at The Home Depot, or the Attic Tent.

Attic Ventilation

Make sure you have proper attic ventilation to keep your attic cooler in the summer and reduce condensation in the winter.

When venting your attic, be sure you have:

  • Soffit vents under the eaves to let outside air in.
  • Gable or ridge vents near the peak of the roof to expel hot air.
  • If you need additional attic ventilation, install an attic vent fan high up in the attic below the peak of the roof.

Hot Water Heaters

To reduce your hot water heating costs:

  • Turn the hot water heater thermostat down to 120° F.
  • Insulate hot water pipes with foam insulation.
  • Drain hot water heaters once a year to remove sediment in the tank.
  • Install a hot water heater timer which can be scheduled to turn the water heater on and off.

Hot water heaters typically last about 10-15 years. When replacing your hot water heater, consider an energy efficient type, such as an:

Energy Efficient Lighting

To save energy on lighting your home:

  • Turn off lights when not in use.
  • Use natural light from windows and skylights.
  • Position mirrors on walls opposite windows to reflect natural light.
  • Replace incandescent light bulbs with CFL or LED bulbs.

Energy Efficient Windows

To make older single-pane windows more energy efficient, consider installing storm windows over the outside of your existing windows. If your budget allows, replace windows with energy efficient, insulated glass windows, such as those from JELD-WEN Windows & Doors, to make a big difference on your energy bills.

You can also reduce your energy bill by caulking cracks and gaps around the outside of your house. When caulking cracks on the outside of your home:

  • Use an exterior caulk that’s mildew resistant.
  • Make sure the caulk is paintable, if you plan to paint over it.
  • Cut the caulking tube at a 45° angle with a small opening.
  • Use expandable foam for filling large cracks and gaps.

Reducing Sunlight from Windows

To reduce the heat and UV rays from sunlight through windows and glass doors, apply window film to single pane windows or glass doors. When buying new windows for your home, make sure the glass comes with a clear Low-E coating to block heat and UV rays.
