You can easily conduct a home energy audit yourself. With a simple, but diligent, "walk-through," you can spot many problems in any type of house. When auditing your home, keep a checklist of areas you have inspected and problems found. This will help you prioritize your energy efficiency upgrades.

I. Identify Potential Air Leaks

First, make a list of obvious air leaks (drafts). The potential energy savings draft reduction may range from 5% to 30% per year, and the home is generally much more comfortable afterwards.

Make a list of common Indoor and Outdoor air leak locations (some examples follow): Windows and doors, baseboards, electrical outlets and switch plates, fireplaces, attic access panels, wall or window mounted A/C units or evaporative coolers, outdoor faucets (hose bibs), electrical, plumbing, phone and cable penetrations through exterior walls, dryer vents, etc.

II. Locate Air Leaks

Simple

Using a stick or burning incense or the back of your hand check each of the locations you noted on your list. Cold air will make the smoke from the incense waver or you will be able to feel the cold air on the back of your hand.

Alternative

If you're having trouble find leaks you can do a simple 'pressurization' test by using the following steps.

1. Close all exterior doors, windows, and fireplace flues.

2. Turn OFF all combustion appliances such as gas burning furnaces and water heaters, gas fireplaces, etc. (Remember to turn them back on when you are done with the test.)

3. Turn on all exhaust fans (generally located in the kitchen and bathrooms) or use a large window fan to suck the air out of the rooms. This increases infiltration through cracks and leaks, making them easier to detect.

4. Use a burning incense stick or your damp hand to locate these leaks. Moving air causes the smoke to waver, and you will feel a draft when it cools your hand.

III. Locate Other Air Leaks

1. Windows and Doors - If doors or windows rattle or are loose in their frames you can expect air leakage. If you can see daylight around door and window frames, then the door or window leaks.

2. On the outside of your house, inspect all areas where two different building materials meet. For example: inspect all exterior corners; where siding and chimneys meet; and areas where the foundation and the bottom of exterior brick or siding meet.

IV. Seal all Air Leaks

CAUTION: When sealing any home, you must always be aware of the danger of indoor air pollution and combustion appliance "back drafts." Back drafting is when the various combustion appliances and exhaust fans in the home compete for air. An exhaust fan may pull the combustion gases back into the living space. This can obviously create a very dangerous and unhealthy situation in the home.

In homes where a fuel is burned (i.e., natural gas, fuel oil, propane, or wood) for heating, be certain the appliance has an adequate air supply. Generally one square inch of vent opening is required for each 1,000 Btu of appliance input heat. When in doubt, contact your local utility company, energy professional, or ventilation contractor.
