Certified Energy Auditor

Who Are Energy Auditors

  • Do you evaluate and analyze energy use in a facility, identify energy conservation opportunities, and make recommendations where consumption can be reduced or optimized?
  • Are you an energy auditor looking to validate your experience and knowledge?
  • Are you a consultant that specializes in energy efficiency upgrades to buildings and building systems?
  • Do you conduct audits and assessments in government buildings and are required to work to the US Department of Energy’s Guide to Energy Audits?

Energy Auditors undertake energy efficiency assessments of large buildings and industrial facilities. Their audits cover building systems, occupancy, operations, maintenance, and code compliance. An auditor aims to provide their client with detailed survey results, risk mitigation analysis, implementation plans, and a final investment-grade analysis. Many auditors work to predefined codes and standards, such as the ASHRAE Standard 211-2018 for Commercial Building Energy Audits.
