Should campuses run HVAC systems 24/7?

Operating all building HVAC systems 24/7 during unoccupied periods of the day would not benefit facility occupants when the building is empty. Instead, we have programmed building control changes that provide an extended building ventilation purge before occupants arrive for the day, and after they leave in the evening. These purge periods have been scheduled recognizing that some facilities have unique and extended hours of operation, and have been tailored to fit these hours.
