An architecture for integrated commercial building demand response

Enthusiasm for commercial demand response (DR) has inspired research efforts to create new building electric load control frameworks. In this paper we introduce a software architecture for an integrated building control system, the Central Load Shed Coordinator (CLSC). The CLSC provides functional control over three building systems which are large power consumers: lighting, HVAC, and plug loads. The system acts upon external demand response signals to meet load-shed criteria, while minimizing occupant inconvenience. In this paper, we present the purpose and relevant characteristics of this architecture. In addition, we discuss its deployment in a UC Berkeley building and present results from preliminary testing.
