In our opinion as Energy Auditor, an energy audit is a survey by an energy auditor to ascertain the amount of energy a building uses and to pinpoint methods for lowering energy usage. These are employed to raise a building's energy efficiency, whether residential, commercial, or industrial. Three components comprise an energy audit: assessment, testing, and recommendations for improvement. A building evaluation is the initial stage. This entails examining previous energy bills and the physical attributes and operation of your building. Inquiries about the building's construction date, usage patterns, and kind of HVAC system will be made by the energy auditor.
