A Guide to Measuring Your Home Energy Efficiency

How much energy are you using in your home on a daily basis? More to the point, how much energy are you wasting in your home, and how much money could you save by reducing that waste? Here's how to measure (and improve) your home energy efficiency.

DIY Energy Evaluation

There are some basic things you can check for when it comes to energy efficiency. How much insulation do you have? The insulation in your attic settles over time, so while it may have been enough when you installed it a few years ago, you might need to replenish it to get the most out of your heating and cooling.

You can also check for air leaks. There are many places where air can leak in from outside, undermining your HVAC system and forcing it to work harder. They include around windows and doors, behind outlets and lightswitches, around baseboards, and more. Check for drafts in those places. Also check your ductwork for holes, tears, and other damage where your HVAC air might be leaking out. Seal these leaks with metal tape or mastic sealant.

Professional Home Energy Evaluation

If you really want to improve your home energy efficiency, call your HVAC technician to perform a home energy audit. They use professional equipment that can spot energy problems you might miss on your own.

With the blower door test, they cover all windows and doors, and suck the air out of your home with a large fan. Then, they use an infrared sensor to spot places where air is leaking in. Infrared cameras can be used too, to take photos of your home that show hot and cold areas.

There are also devices to test your windows, to see if they're treated with low emissivity coating. This coating reduces heat transfer, saving energy. Once the results of the evaluation are in, your technician can recommend ways to make your home more energy efficient.
