A commercial energy analysis, AKA an electrical load analysis, is like a pre-flight checklist where trained, professional airline mechanic checks every part of the plane to ensure flight-worthy. In addition, these checklists determine where possible problem areas are developing that may need to be addressed soon.
A commercial energy analysis studies your building’s energy requirements and how that energy is used to see what improvements can be made to improve your energy efficiency, resulting in energy savings. For the same reasons that you want a trained and qualified airliner mechanic to be reviewing your plane’s operations, you want to make sure that your commercial energy analysis is performed by an accredited professional from organizations such as the American Society of Heating, Refrigerating Air Conditioning Engineers (ASHRAE), the Association of Energy Engineers (AEE), or the Building Performance Institute (BPI).
You can find DIY commercial energy audit instructions online, but why would you do it? It may save you some money in the short term, but why? A certified pro has all the knowledge, training, and specialized tools necessary to conduct comprehensive and accurate testing of your building’s energy equipment.
ASHRAE has identified and categorized three levels of commercial energy audits that can be performed for your company. The Level I audit is a high-level energy survey that consists of a review of the company’s utility bills and a brief visual inspection of energy-consuming equipment within the company buildings. The objective of a Level I Energy Audit is to deliver a simple overview of the energy-saving changes for the building using low-cost or no-cost measures. The suggested actions may include educating employees on energy conservation, making minor upgrades to lighting or thermostat controls, or recommending a more comprehensive commercial energy analysis (a Level II or Level III energy analysis).
The Level II Commercial Energy Analysis digs in deeper within the company’s facilities and equipment, looking at its use, when it is used, how it is used, and more. Typically this also includes comprehensive interviews of owners and managers as well as the equipment operators, maintenance staff, and other front-line workers to learn how the building operates, identify problem areas, and solidify the goals of the analysis.
The energy analysis auditor studies the business’s electricity and natural gas consumption to see where opportunities for savings exist. Additionally, the auditor will review utility rates for electricity and natural gas to see if switching to another energy plan or provider would be cheaper.
In addition, the commercial energy analysis auditor closely examines all equipment within the business that uses energy. This includes heating, cooling, lighting, air circulation, and other specialty systems. The auditor looks at the equipment’s age, size, condition, technology, and how it operates.
Level II Commercial Energy Analyses often include an in-depth infrared scan to see where heat escapes from the building(s) to determine if better insulation or other infrastructure upgrades are needed. Once the audit has been completed, the auditor typically delivers a comprehensive report to the company’s management and staff about the findings. This includes recommendations for new energy efficiency measures, system control changes, operation, procedural changes, and potential capital upgrades. These recommendations also include implementation costs and how long it will take the company to recoup its new equipment/processes investment before it’s paid back.
A Level III Commercial Energy Analysis is sometimes known as an investment-grade energy analysis because it provides more details about the performance, costs, and benefits of implementing the recommendations described in the Level II analysis. Level III analyses typically use a computer model to simulate how a building reacts to changes in its energy systems or modifications to its structure. This is possible due to more detailed data collection over weeks or even months to track equipment operation such as pumps and motors, temperature, humidity, lighting, and more. The goal is to construct the computer model to react just like the actual buildings act so that simulated changes within the model will work with the real building and deliver accurate data.
Another significant component of a Level III analysis is the use of benchmarking to compare the energy use of your building with other buildings that have similar characteristics. This often involves using Portfolio Manager, a benchmarking tool used by the federal government’s Energy Star program. This program rates your company’s buildings on a scale of 1 to 100. A building scores a rating of 50; for example, it’s typical of similar facilities in terms of energy efficiency. A rating of 25 means your building requires significant improvements and measures to bring it up to the standards of other similar structures out there.
A commercial energy analysis will lead to savings in your monthly energy bills, no matter which level of analysis you choose.
