Commissioning refrigeration systems has a significant impact on energy efficiency. A well-commissioned system ensures that all components are operating at optimal performance, reducing energy consumption and operational costs. This is achieved by verifying that the system is operating within design specifications, optimizing system settings, and identifying opportunities for energy savings. According to the U.S. Department of Energy, commissioning can result in energy savings of up to 20% in existing buildings and up to 10% in new buildings.
