What is a whole-house energy audit?

Infrared Energy AuditYour utility bill may be shocking, but it offers few helpful details: it doesn't tell you when your energy use peaks, doesn't explain how best to reduce power consumption, and doesn't tell you how your home is spending your money.

We believe these are things worth investigating. And home energy audits, like those provided by professionals in the CHERP community, are a first step in understanding your home's energy usage, as well its overall health and performance. Through a combination of high-tech tests and common sense evaluations, a qualified home energy auditor provides a list of energy and money saving steps, and explains how your house is using energy.

A home energy audit is comprised of several steps:

1) A thorough visual inspection of the home's building envelope.

2) An insulation check, generally involving infrared thermography, to pinpoint spots where insulation may have settled, been improperly installed, or where it may be missing altogether.

3) An air leakage test using a blower door, to measure the cumulative effect of all the air leaks in the home.

4) A ventilation check: healthy houses have appropriate ventilation, and an auditor will test ventilation systems to ensure that they conform to safety standards.

5) All visible gas lines, the gas stove, and gas powered water heater will be examined to ensure that there are no leaks.

6) The auditor will evaluate if your central heating system needs cleaning or a tune-up.

7) Finally, expect a few suspect appliances, including old driers or refrigerators to be tested with an electricity monitor. There are times when one terrifically inefficient appliance throws an entire house's energy use out of whack.

Whole house energy audits by certified professionals are worth every penny, so long as you act on what the audit turns up. We encourage to learn more about the energy audit process and its benefits, and if you live in the Claremont, CA area, consider a CHERP professional for your home efficiency test. 

Homeowners are often shocked to discover that all the little air leaks throughout their house add up to the equivalent of a window (or two, or more) being left open year round! Contact us today to see how you can get started on the road to energy efficiency.
