Does the institution use a centralized energy management system that allows it to track energy consumption and performance in multiple buildings in a central location?:
Yes

A brief description of the management system:

Auburn University uses the Johnson Controls (JCI) Metasys system for managing building systems. All of our DDC (Direct Digital Control) technology is mapped into Metasys. We are able to trend data from the points mapped into Metasys. This allows us to monitor the usage of equipment and diagnose when problems arise. It also provides a vehicle to monitor the effect of energy management improvements that are made within the buildings. Our chilled water and hot water systems are metered through the JCI system. Even buildings with pneumatic technology, have some points mapped into the system. It may stop at the chilled and hot water interfaces that supply the heating and cooling to the buildings, or it may go down to the air handler level.


The percentage of building space monitored with a centralized energy management system:
55

A description of what systems are shut down during unoccupied periods:

Our philosophy on setbacks is to scale systems back where possible to achieve the bulk of the savings. From the Affinity Laws: Power = Speed3. The majority of the savings can be attained by backing down the systems. The gain achieved by turning everything off is minimal in comparison. This allows us to protect the indoor environment while we greatly reduce the energy use. We do shut down our building chilled water pumps when there is enough system pressure to push the chilled water through the buildings. In the cases of pneumatic buildings, we schedule air handlers to be shut down where system sensors are present to monitor the temperature and humidity of the spaces served.
