Pictured here is Michael Brambley in front of equipment that supplies chilled water to PNNL Building Diagnostics Laboratory's air handler. The cooled air from an air handler is distributed to terminal boxes, which are the last point for controlling air temperature and flow before distributing it throughout a building zone. In a new control strategy for commercial buildings, the terminal boxes would process the information collected by occupancy sensors to control the air handler's fan speed for energy savings. | Photo courtesy of Kristin Nolan, freelancer.
