Retro commissioning (RCx) is a proven, cost-effective approach to improving the performance of existing buildings by identifying low-cost operational improvements. One of the most impactful yet often overlooked opportunities is optimizing lighting systems through advanced lighting controls, which can significantly reduce energy use and operating costs with little to no capital investment. During the RCx process, building teams evaluate space usage, lighting levels, and occupancy patterns to align lighting operation with current facility requirements. Advanced controls—such as occupancy and daylight sensors—enable dynamic light adjustment so spaces are illuminated only when and where needed, often delivering 20–40% energy savings while enhancing occupant comfort. This webinar is ideal for facility managers, energy professionals, and building owners looking to achieve fast, measurable savings and long-term performance improvements through RCx.
