    • Window types (e.g. single-, double-, or triple-paned, tinted, solar coatings)
    • Roof and outside wall material type (e.g. concrete, wood, etc.) including R-values
    • Energy inputs (natural gas, electricity, etc.)
  • System types, including age and efficiency
    • Central air, window air conditioners, hot water, boiler, furnace, unit heaters, baseboard heaters, radiant heaters
    • Thermostat settings including variable temperatures by time periods if using a programmable thermostat

    • Details on interior and exterior lights, including number, type, wattage, and average operational time
    • Details on automatic doors, elevators and escalators including number, type, age and use-patterns
    • Details on any seasonal equipment, like dehumidifiers and irrigation systems
  • A listing of all tools, equipment and appliances including number, type, location, age, condition, efficiency, use-patterns and size

How to Find an Energy Auditor

Professional auditors can be a good option for many businesses. At a minimum, they should conduct a blower door test, a thermographic scan, and a PFT air infiltration measurement as part of the assessment.

Your first call should be to your utility as they may provide free or low-cost energy audits, and offer financing, incentives and rebates if their recommendations are implemented.

If you are interested in hiring a professional auditor, browse the Department of Energy’s Plant Energy Auditing resource page or check out the Residential Energy Services Network. Many of these auditors are primarily home auditors but are also qualified to conduct business audits.
