A Home Energy Survey Professional (HESP) is certified to perform a visual walk-through evaluation to ascertain the general energy performance of an existing home including:

• Utility billing history
• Building envelope features (windows, doors, insulation, ducts) and ages
• Heating, cooling and ventilation equipment types, characteristics and ages
• Appliance and lighting characteristics
• Comfort complaints
• Visible moisture issues
• Visible health and safety issues.

While a Home Energy Survey does not include the use of diagnostic testing equipment, the HESP is well trained to provide a fundamental energy assessment, identify problems and make basic recommendations for improving the home's energy efficiency including low-cost do-it yourself tasks. A HESP will also present information on relevant utility-based programs that may help incentivize you to take action.
