As you may already know, we supply home energy auditing for our customers, usually as part of larger home-renovation projects. It’s with these larger projects that we attend to enough area of the home to really affect the home’s total energy performance. But even with smaller projects, energy efficiency is top of mind during design and construction.
As part of the home efficiency testing, auditors get a look at past utility bills and existing appliances, and they test the tightness of the home. They should also test for indoor home air safety, including C02 and other toxins. We find that drafty windows and doors, uninsulated spaces in walls, and breaks in the vapor barrier or thermal envelope of the home are the usual sources of air leaks. And air leaks are very costly because they cause you to use more energy keeping your home comfortable in hot or cold weather.
