The building envelope includes the parts of your house that separate the outdoors from the indoors such as exterior walls, roof, foundation, windows & doors. This building envelope requires regular inspection and maintenance to work properly, just like your car.

Gaps that leave an incomplete building envelope can be found in every room in the home, like around window and door frames, electrical and gas service entrances, outdoor water faucets, where dryer vents or cable lines pass through foundation walls, and where basement walls meet the ceiling or floor.

Checking for air leaks will help you discover problem areas throughout your home. This is very easy to do yourself.

First, print these step by step instructions to take with you as you check your home for air leaks. (Print button is in the top-right corner.)

Keep Track of How Much Money You Save!


Try the Energy Star calculator that compares your home’s energy consumption to national averages and based on the results gives you a list of ways to improve your home’s energy efficiency.

You will need your home’s last 12 months of utility bills (usually found in the 12 month summary provided on your bill or through a Green Button file.)

Print off the results of your evaluation and file it for reference next fall with the receipts for your caulking so you’ll be able to compare your savings to your costs.
