Project Time: Approximately 1.5 hours

Complexity:

Test #1 - The Dollar Bill Test: Place a dollar bill between the door jam or between the window sash and sill. With the door or window closed, attempt to remove the dollar bill. If it slides out easily, you are losing energy.

Test #2 - Flashlight Test: Shine a flashlight around the edges of your door at night. If you can see light from the other side, you're losing energy.

Test #3 - Moist Hand: Pass a moist hand around the edge of your doors and windows. Where you feel a draft, you are losing energy. This test works best on cold, windy days.
