Having an energy audit completed for your commercial facility can help you gain valuable insight into the most cost-effective ways to improve your building’s energy use and reduce your energy bills. The options available for energy audits vary in depth, complexity, and cost, depending on the potential at a specific site for energy and cost reductions and the objectives determined by the customer. According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standards, there are three levels of energy audits as summarized in the chart below. When you are preparing to have an energy audit completed, it is recommended to have at least 2 years of fuel usage and cost data available so the auditor can create a more accurate report tailored for your building.
If you are interested in a commercial energy audit, consider taking advantage of HG&E's Commercial Energy Conservation Program, which provides financial assistance at 0% interest for energy audits as well as various energy efficiency and electrification projects. Qualifying industrial customers may be eligible for a free facility audit through the University of Connecticut Southern New England Industrial Assessment Center, which is supported by the U.S. Department of Energy.
