Key Players

• Dave Ruby, CITES ICS
• Lab supervisor, CITES ICS
• Eva Sweeney, Electrical Engineer, FS
• Sanja Koric, Electrical Engineer, FS
• Robert Halverson, Supervising Engineer, FS

13
Approach

• Install electrical sub-metering, separating
  computer power from HVAC and other major loads
• Monitor power consumption over time for varying
  modes of ICS lab operation
• Analyze data for operating modes that save energy
  (or not.)
