Residential Energy Auditor

Residential Energy Auditors conduct onsite energy audits and assessments and perform energy modeling to determine the current and desired energy performance, safety, and durability of single family buildings.

A Residential Energy Auditor is a specialized consultant who helps assess and improve the energy efficiency of residential buildings—in essence, a building inspector who focuses on energy efficiency measures. They provide homeowners with specific and actionable recommendations to improve the home's level of energy efficiency, increase comfort, support health and safety, and create cost-savings on utility bills. Residential Energy Auditors also assess a site for additional health and safety concerns including, but not limited to moisture, mold, and asbestos.

Residential Energy Auditors begin by visiting a home and conducting a visual inspection. They talk with homeowners and discuss their comfort level in the home as well as how much they spend on their utility bills. Residential Energy Auditors perform tests such as blower-door tests to locate air leaks and determine how much energy a home might be losing through the building envelope. Energy Auditors also use digital thermometers, air velocity monitors, light meters, and other tools to help them analyze energy use in the home. After the visual inspection and on-site tests are complete, Residential Energy Auditors prepare a report that includes the inspection and test results as well as recommended energy efficiency upgrades and improvements and possible financial incentives. The audit report includes potential cost savings calculations for particular upgrades and might compare minor versus major upgrades, for instance adding weather stripping to single pane windows compared to replacing windows completely with dual-pane glass. Energy Auditors must provide cost-savings to justify the expense of energy efficiency upgrades.

Education is a key component of a Residential Energy Auditors job as a customer's level of awareness varies when it comes to the factors that impact their home's energy use. Energy Auditors have the ability to motivate customers to reduce energy usage, increase sustainability, and invest in energy efficiency upgrades.
