ENERGY INSPECTION

A home energy assessment, also known as an energy audit, can tell you how much gas and electricity your house consumes and identify ways you can make it more efficient. An assessment will show you problems that, when fixed, save you 5% to 30% on your utility bills.

Energy audits typically cost $0.08 to $0.50 per square foot with a minimum cost of $100 to $200. A larger house increases the total price. For a 1,200 square foot home, expect to pay $100 to $150 while one in the 2,500 to 5,000 square foot range will run $200 to $300. Most companies charge a flat rate.

• Simple assessments: $0.08-$0.12 per square foot. Take between 1-3 hours. These are generally just a visual walk through of your property.
• Moderate to extensive tests: $0.12-$0.50 per square foot. Take anywhere from 3-6 hours to complete. These use manual and mechanical testing to look for leaks, inefficient electrical use and poorly performing appliances. You’ll also receive a thorough review of past energy bills to determine potential areas for improvement.

When the professional comes to your home, they will perform a variety of tests depending on the level of audit you requested.

Simple audits:

1. 1. An explanation of the process.
   2. A walk-through visual inspection, including one or more of the following:
      • Exterior walls, foundation and roof.
      • Heating and cooling system.
      • Water heating and usage systems.
      • Ductwork and ventilation.
      • Doors and windows.
      • Appliances and lighting.

Advanced audits include everything from a simple analysis and one or more of the following:

1. 1. 1. An analysis of energy usage.
      2. Manual tests, including one or more of the following:
      • Blower door test: A blower door test determines air-tightness by finding leaks.
      • Infrared scanning: thermography or infrared scanning to detect thermal defects and air leakage in building envelopes.
      • Duct leakage testing.
      • Moisture testing.
      • Appliance and wattage testing.
