A Commercial Energy Evaluation (CEE), also known as an energy audit, is the first step in determining how and where energy is used in your business and overall operations.
One of the most important steps after doing energy-efficient upgrades or retrofits to your home or business is actually verifying that the estimated energy savings were achieved.
