Home Energy Audits

April 13th, 2010 - Posted by RESNET under Energy Auditor Information, Energy Efficiency, Solar Energy

You may be wondering if having a home energy audit is a good idea. Why should you consider it?

Except for new homes which have been built to high energy efficient standards, most homes – even brand new ones – are inefficient. The older the home, the more inefficient it is likely to be. As a result, you are probably paying more for utilities than you need to, create more pollution which is harming the environment, and live in a home which is not as comfortable as it could be. A home energy audit can detect poor indoor air quality (due to mold, mildew, toxic gasses, allergens and other irritants) which may be affecting your family’s health.

What is an Energy Audit?

A home energy audit finds areas in your home where you could make changes leading to energy savings, lowering your utility bills, reducing waste and making your home more environmentally friendly. The ultimate goal of home energy audit is to help your house operate more efficiently, safely and comfortably.

A professional, certified home energy auditor inspects all the energy features of the home including appliances, and uses equipment such as a blower door to measure the extent of air leaks, and an infrared camera to reveal hard-to-detect areas of air infiltration and missing insulation. The auditor will provide you with a report of the information gathered along with a list of all recommended measures to increase energy efficiency, lower your utility bills and increase comfort. Costs, energy savings, dollar savings and return on investment (ROI) are also included.

Comprehensive home energy audits last about 3 to 4 hours, depending on the size of the home.

Do you Need a Home Energy Audit?

While virtually all homes can benefit from a home energy audit, the following are signs that there is an imminent need for an inspection:

  1. Unusually high energy bills. An energy audit can find the culprits.
  2. Drafts or inconsistent hot and cold areas in your home.
  3. Unexplained dark spots or stripes on floors, ceilings or walls (you may have water damage or other associated problems).
  4. Mold or mildew.
  5. Condensation on windows or glass doors.
  6. Moisture or dampness in basements or attics.
  7. Poor air circulation or bad air quality. A home energy audit will help you identify and fix the problem.

Types of Energy Audit

There are several types of home energy audit, ranging from a simple visual inspection or survey, up to a comprehensive audit using diagnostic equipment. The various types of audit are explained in detail in the article What is a Home energy Audit?

Cost

Home energy audit pricing is generally based on the type of audit being conducted and the square footage of the building. For residential homes, the cost of a comprehensive audit is generally around $400. For homes over 2000 square feet and additional charge may be added. The full report of building information and recommended remedial measures is included in the price.
