Energy auditors visit homes, businesses, and other buildings to inspect equipment, structures, and materials. They use computers to analyze data and identify where energy is wasted. You'll measure insulation, check heating and cooling systems, review utility bills, and talk with building owners about what you find. The job requires you to stay current with building codes and energy-saving technology. You communicate findings clearly so clients understand their options for improving efficiency and lowering costs.

Top skills
Knowledge areas
Most energy auditors start with a high school diploma or equivalent. You'll need on-the-job training to learn how buildings work and how to use diagnostic tools and software. Many employers provide this training as you work. You should be comfortable with math and physics concepts, and willing to learn building systems and energy standards. Some people move into this role from related construction or mechanical jobs. Check with local employers and trade organizations about apprenticeships or training programs in your area.
Paths into energy auditing include starting as a helper on construction sites, moving into HVAC or building maintenance, or jumping in directly with employer training. If you are exploring which route fits your timeline and interests, Pathly can map the energy auditor path that fits you and work through it with your counselor to find the best next step.
