Energy Audit is an inspection survey that analyses energy consumptions in various parts of a building, industrial or commercial facility with the aim of energy conservation in a building, process or system to reduce the amount of energy input into the system without negatively affecting the output(s).
The Purpose of Energy Audits
The purpose of an energy audit is to analyze the energy flows in a building, and understand its energy dynamics. During the energy audit, the auditor looks for opportunities to reduce the amount of energy input into the building without negatively affecting the output(s). Beyond simply identifying the sources of energy use, an energy audit seeks to prioritize the energy uses according to the greatest to least cost effective opportunities for energy savings.
The Energy Audit Process
The process of conducting an energy audit can be very simple. First, the energy auditor will obtain the energy bills for a minimum of 1 year for the building. The current energy data is used to create a baseline and establish what the current energy costs are. Next the auditor conducts a room-by-room inspection of the building. During the room-by-room inspection, the auditor examines energy consuming items as well as areas that waste energy. With the new information obtained during the inspection, the auditor then calculates the current energy usage and proposed energy saving and document the findings into a summary report.
Types of Energy Audits
A home energy audit focuses on reducing energy costs within single family homes. A residential energy audit focuses on energy wasting factors such as air leakage plus energy consuming factors including heating, lighting, and more.
Commercial energy audits are designed specifically to help business owners reduce costs. As small and large businesses continue to struggle with economic strain in the current economy coupled with lower consumer demand, one area they are now looking at is energy efficiency.
