Home Energy Audits

Littleton Electric Light Department offers a Home Energy Audit to help customers save energy in their homes.  We support a two-tiered approach to energy conservation.  Our Energy Services department is always available by phone to answer your questions about energy efficiency or conservation.  Additionally, if you are unable to have your questions answered through the above means, then we will be happy to provide you with a complimentary energy audit.

What to expect

We will send a professional energy advisor to your home to evaluate your energy saving potential in specific areas of your home.  The advisor will provide useful information and tips on appliance usage, air sealing, insulation and will give you a computerized report detailing recommendations and payback time for any improvements suggested.  The entire audit usually takes about 1-1/2 hours to complete.

How to prepare for your audit

Be prepared to answer some of the following questions to help the auditor in their work:

1. Is anyone home during working hours?

2. What is the average thermostat setting for summer and winter?

3. How many people live here?

4. Is every room in use?

Your answers to these questions will help the auditor identify some simple ways for you to reduce your energy consumption.

Follow these simple tips, and you can start saving today.

Heating & Cooling Energy efficiency is in the air. Your heating and cooling system is the perfect place to start when making energy-saving changes.

  • Install a programmable thermostat.
  • Set thermostats to 78 degrees Fahrenheit in summer and 68 degrees in winter.
  • Keep air vents open to increase circulation.
  • Use fans to cool your home.
  • Have your A/C and heating system serviced twice a year (during spring and fall).
  • On a new A/C unit, look for a 16 Seasonal Energy Efficiency Rating (SEER) and 12 Energy Efficiency Rating (EER) rating.
  • Clean or replace air filters once a month.
Insulation With the proper insulation, you can keep your heating and cooling system from working overtime. Insulating your attic can reduce your heating and cooling needs up to 30 percent. The minimum recommendation for insulation amount in most attics is R-30, or about 9 to 14 inches, depending on the insulation type.
Lighting Conserve energy with the flip of a switch by choosing the correct lighting.  Install energy efficient light bulbs. They use approximately 70 percent less energy than an incandescent bulb and last up to 10 times longer.  Use sunlight to illuminate your home. It’s free!
Air Leaks Controlling air flow helps control your savings. Properly sealing air leaks can significantly reduce your heating and cooling costs.

  • Watch for these signs that your ducts aren’t performing correctly:
    • Rooms are difficult to heat and cool.
    • You have stuffy rooms.
    • You find your flexible A/C duct is tangled or has holes in it.
  • Seal air conditioning ducts properly to help reduce the amount of heating and cooling needed to keep your home comfortable.
  • Install foam gaskets behind outlets and switch plates on exterior walls to stop air from leaking
Doors & Windows Close the door on air leaks for good. By focusing on two of the top spots for gaps in your home, you’ll be one step closer to an energy-efficient home.  Weather-strip and caulk around windows and doors to prevent drafts. A gap of just one-quarter inch can let in as much air as a softball-size hole.  Consider ENERGY STAR®-qualified window models and low E-Glass windows. Their special coating will reflect infrared light, keeping heat in during winter and out during summer.   A low-cost alternative to new windows is installing solar screens.
Get plugged in to an energy-efficient home with appliances and electronics that are designed to conserve. Appliances and electronics can account for 20 percent of a home’s electrical costs. Replace old appliances with ENERGY STAR®-rated models. Unplug electronics when they’re not in use. Certain electronics, such as a cell phone charger, continue to draw electricity when left plugged in – even if they’re not in use.
Water Shower yourself in savings by making small changes to your home’s water system.

Set your water heater temperature at 120 degrees Fahrenheit to save on water heating.

Insulate the hot water heater and your heating and cooling pipes that are not in enclosed areas. It can reduce heat loss by 25 to 40 percent.

Trees Trees are a natural solution for energy-efficient changes. Remember: When planting a tree, type and location are key. Proper tree placement can reduce home heating and cooling costs by 20 percent. Plant trees 35 feet from your house and 25 feet from power lines. Plant deciduous trees (trees that lose their leaves). They will shade your house in summer, and help warm your home in winter by letting light through.


Smart Home Improvements

*Smart Home Improvement Credits apply to Electric Heating Customers Only.

Make the energy-efficient home improvements recommended by an LELWD energy audit and you could qualify for a credit on your electric bill equal to 20% of the cost of the project, up to $300 per year. At the completion of your home energy audit, discuss with the energy advisor the process for making improvements and claiming the incentive.

Typical energy-improvement projects include:

  • Adding insulation to the attic, basement, rim joist, walls and pipes
  • Weather-stripping windows and doors
  • Replacing exterior doors, storm doors, and storm windows with energy-efficient models

Once the work is completed, call LELWD at 978-540-2222 to arrange for an energy advisor to inspect the installation. If the work passes inspection, you will receive a credit on your electric bill.
