IS-2006-62: Advanced Controls and Communications for Demand Response and Energy Efficiency in Commercial Buildings

This paper from Lawrence Berkeley National Laboratory explores the potential of demand response strategies to reduce peak electricity demand from commercial buildings. These buildings account for 45% of the summer peak demand, which is estimated at 330GW nationally. Demand response may include limiting total usage (the demand) and load curtailment. These actions are motivated by time-of-use electricity rates, real time rates, or event notifications. A trial was described that achieved an average of 8% demand shedding with a peak of 56%. Demand response will not be a major driver for new building control systems but should be accommodated.
