An energy auditor inspects and evaluates a home’s energy efficiency, measuring energy usage, tracking heating and cooling losses, and checking HVAC systems. They need experience in construction or home improvement, technical skills, and the ability to explain systems to homeowners. Specialized equipment is used, and certification programs are available. Homeowners can benefit from energy-related upgrades, which can increase home value and attractiveness to buyers. Some US states require home energy audits before selling. The RESNET Certified Energy Contractor license is popular in the US.
An energy auditor is a person who inspects and evaluates the energy efficiency levels of the home. As part of this inspection, the energy auditor will measure energy usage, track heating and cooling losses, and check the operation and efficiency of heating, ventilation, and air conditioning (HVAC) systems. Based on the audit findings, he will discuss the benefits of potential energy upgrades and improvements with the homeowner.
To perform a comprehensive energy audit, it helps to have some experience in construction or home improvement. Some skills that are especially useful for an energy auditor include an understanding of green building and energy efficiency, as well as experience with HVAC installations or inspections. While these technical skills are important, it is also vital that the energy auditor be able to discuss these systems with homeowners in terms that are easy to understand. The energy auditor should also understand the basic cost of energy-related improvements, as well as the impact these improvements have on home values and utility bills.
The energy auditor must learn to use specialized equipment to help with home energy inspections. One of the primary tools of the energy auditor is a ventilation unit used for fan door tests. This test involves measuring changes in air pressure levels to find potential air leaks through the walls of the house. Energy auditors also rely on infrared cameras to measure changes in temperature, pinpoint the source of drafts, and measure wall insulation.
The demand for home energy auditors is closely related to the growth of the green building movement. In nearly a dozen US states, home energy audits are required before a home can be sold. Even when an audit isn’t required, homeowners can greatly benefit from performing energy-related upgrades to their homes. These upgrades reduce energy consumption, help protect the environment, and lead to lower heating and cooling bills. Improving energy efficiency can even increase the value of a home and make it more attractive to buyers.
Many states and cities in the United States offer certification programs for energy auditors. For those in other areas, there are a number of independent certificate programs that can help candidates learn more about the profession and establish credibility with clients. The Association of Energy Engineers offers a Certified Energy Manager (CEM) license that is recognized throughout much of North America. Applicants who possess a combination of education and experience as an energy auditor can apply for the CEM license.
One of the most popular licensing programs in the United States is the Residential Energy Services Network (RESNET) Certified Energy Contractor (CER) license. While there are no educational requirements associated with the CER program, applicants must pass a written exam and perform a supervised home inspection to demonstrate their ability. Homeowners who wish to have their home certified under the US Energy Star program must hire a licensed CER energy auditor to inspect their home.
