Home Energy Audit

Home energy assessment to evaluate what efficient measures will be your biggest bang for your buck.

A home energy audit, also known as a home energy assessment, is the first step to assess how much energy your home consumes and to evaluate what measures you can take to make your home more energy efficient. An assessment will show you problems that may, when corrected, save you significant amounts of money over time.

Upgrades following an energy audit can save you money and improve the comfort of your home.

Professional energy assessments generally go into great detail to assess your home’s energy use. The energy auditor will do a room-by-room examination of the residence, as well as a thorough examination of past utility bills. Many professional energy assessments will include a blower door test. Most will also include a thermographic scan. There’s also another type of test — the PFT air infiltration measurement technique — but it is rarely offered. Check out the Energy Saver 101 home energy audit infographic to get an idea of what energy auditors look for and the special tools they use to determine where a home is wasting energy.

Air Duct Leakage Testing


Leaks in forced air duct systems are now recognized as a major source of energy waste in both new and existing houses. Studies indicate that duct leakage can account for as much as 25% of total house energy loss, and in many cases has a greater impact on energy use than air infiltration through the building shell. Just as important, duct leakage can prevent heating and cooling systems from doing their job properly, resulting in hot or cold rooms, and humidity problems. Worse yet, duct leaks can create air quality problems by pulling pollutants and irritants directly into the house.

Blower Door Testing

These tests determine the air infiltration rate of a building. Blower doors consist of a frame and flexible panel that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow. This will help determine where to apply your money to help make your home energy efficiency discussions.
