This study investigated the potential energy savings from implementation of 34 basic and advanced controls measures and eliminating common faults in heating, ventilation and air conditioning systems in the U.S. commercial building sector. The energy modeling also relied on packages of measures that represent a diversity of current status of building controls and equipment faults (inefficient, typical, and efficient), and compared those packages to an ideal building representing a reasonable approximation of best practice in all areas of building control. The difference between the current state of building controls and the ideal state is the assumed savings potential. This report was prepared by Pacific Northwest National Laboratory with support from the Energy Department’s Building Technologies Office.
