Home Energy Audit

Brought to you by Greening Neighborhoods

Greening Neighborhoods is a non-profit organization dedicated to reducing household use of nonrenewable energy and water.


The City of Dunwoody is pleased to announce a competition where every participant wins: the household energy & water challenge. We’ve worked with local non-profit Greening Neighborhoods to bring you a quick and easy way to evaluate the energy and water you use and give suggestions on how to reduce your usage. Energy and water savings translates into dollars and resources saved. Directions are below. A few big winners will get an additional upgrade kit with some premium supplies.

The Home Energy Audit is a simple way households can take stock of how much energy and water we consume. Over 21% of all energy used in Georgia is consumed in our homes and 32% is used from transportation. As households we have the capacity to reduce by 1/3 the amount of energy we use and by 1/2 the amount of water we use. Doing so will help our communities become greener and healthier, while reducing our utility bills and improving our level of comfort. It's a win-win course of action.

To get started follow these steps:

  1. Measure and fill in the Home Energy Audit. The Audit shows goals to meet for each of its four categories: water consumption, electric consumption, heating and cooling, and transportation. Goals are based on best practices and/or national averages.
  2. Enter your email address. By doing so your data will be shown on a spread sheet. The data will be archived by Greening Neighborhoods only for the purpose of this contest.
  3. After you have submitted your results see if you met or beat the goals indicated for each category. If you fall short there are links you can click showing ways to improve consumption.
  4. Make the indicated improvements to your home or to your patterns of behavior.
  5. Measure and fill in the Home Energy Audit when you have finished step 4.
  6. Once again enter your email address and submit your data. Your improvement will be the basis of the contest, where everyone is a winner.



How many gallons of water is used in one minute (gpm).

With a measuring cup, fill it for 10 second, pull the cup away, see how full it is and multiply by 6 to get the amount of water used in 60 seconds. You can do this for 2 seconds and multiply by 30. Then divide the number of cups by 16 to get gallons.

16 cups = 1 gallon

Goal: 0.5 gpm for each faucet

If greater than 0.5 gpm see aerators


How many gallons of water is used in one minute (gpm).

With a measuring cup, see how much water you use in one minute the same way you did your faucets.

Goal: 1.3 gpm

If greater than 1.3 gallons see aerators

All Faucets and Showers

How many gallons of water are used before it is hot?

With a measuring cup, see how much water you use until the water is hot.

Goal: 30 seconds = 0.25 gallons (1 quart)

If it take longer than 30 seconds see the instant off device, which saves water and delivers hot water faster.


How much water does it take to flush your toilet in gallons/flush (gpf).

Most toilets have the gpf printed on the tank. If not, flush your toilet and turn off the water valve. Now fill the tank by hand and measure how much water it takes to fill the tank to its "full" mark. This amount of water will be your gpf.

Goal: 1 gpf

If greater than 1 gpf click Low Flow and Instructions for a simple dual flush converter


Light Bulbs

Count the number of standard light bulbs vs the number of CFL/LED bulbs. One CFL lasts as long as nine standard incandescent bulbs and uses less electricity in the process.

Goal: replace all incandescent lamps with CFL's or LED's

See LEDS are getting cheaper

Appliance Energy Rating

Check if your Refrigerator, Dishwasher, Clothes Dryer, Washing Machine, and Water Heater are Energy Star Appliances.

Often there are special discounts on Energy Star Appliances

Appliance Checklist

You can save energy by completing these three simple tasks.

Power Vampires

Check for power vampires. These are electronic devices that waste electricity even when not "on".

These include phone chargers, appliances and even "sleeping" computers, which still use energy when not in use. Unplug them when not in use.

Goal: zero power vampires plugged in

Check to see how many windows are insulating glass (double paned) How many are single paned?



Door and Window Air Leaks

Check doors and windows for air leaks.

See if you can feel wind blowing in through cracks.

Goal: Make all doors and windows air tight by adding weather stripping

See Weather Stripping

Outlet & Switch Plate Air Leaks

Check exterior wall outlet and switch plates.

In winter, if the plates feel cold to the touch, outside air is entering your home.

Goal: At least 9 inches deep (for R 30)

See Attic Insulation


Car Mileage

Keep track of car mileage for one week (7 days).

Reducing car travel is the way we can save the most money. By walking, biking, carpooling and taking public transportation, we can save thousands of dollars a year.

*for trips in a hybrid car divide by 2 for trips in an all electric car enter 0 for miles

Goal: Number to beat is the U.S. average of 260 miles.

Number of trips per week substituted for car travel:
