Many loads that seem essential may be reduced briefly. A building’s own thermal inertia may mitigate the impact of (for example) raising chilled water temperature. Here are some other practical tips to get the most out of a demand-response program:

  • Reduce or shut off non-essential lighting (e.g., corridors having windows, lobby, atrium)
  • E-mail occupants asking them to turn off non-essential plug loads such as coffee makers
  • When acceptable, minimize outside air intake
  • Reduce number of running elevators
  • Sequence speed reductions of fans running on VSDs
  • Shut off electric reheat coils, raise cooling discharge temperatures
  • Allow summer room temperature to briefly float a degree or two higher
  • Cycle electric dehumidifiers, or allow humidity to briefly rise
  • Cycle or sequence electric hot water heaters/boilers
  • Shift process loads to off-peak. For example, charging of electric carts
  • If available, switch to a non-electric chiller
  • If allowed, run on-site generation.

Important: Before deploying any of these options, test it in advance to verify acceptability.
