An energy audit is a professional assessment of how a building uses energy and where efficiency can be improved. Auditors evaluate HVAC performance, insulation, air leakage, lighting, and appliances to identify waste and recommend upgrades that reduce energy use and utility costs. Audits can be simple walk-throughs or comprehensive tests using tools like blower doors and infrared cameras.
