The potential opportunity for electric load shedding/shifting of building systems in response to real-time pricing can be significant, providing a cost-reduction benefit for commercial building customers as well as a load-reduction benefit for their electric utilities. This report documents the results of a research and development program to address this opportunity. The objective of the program was to develop and demonstrate automated control strategies for commercial building mechanical and lighting systems in response to real-time pricing (RTP) of electricity. Under this program, automated energy control strategies have been developed for application to typical commercial building HVAC systems (i.e., air handling system fans, pumps, etc.) as well as for other major electrical loads (i.e., lighting, large appliances, etc.). The control strategies are configured to respond to real-time prices while also taking into account other user-defined criteria (i.e., occupancy schedules, space temperatures, and other building data). Automatic RTP Load Control technology can enable shedding and/or shifting of the electric load from building systems (typical durations might be from 1 to 3 hours) during high-RTP periods. This system enables the commercial building sector to take better advantage of RTP as an important demand-side management option while helping reduce a utility`s reliance on high-cost or purchased energy during peak demand periods. The new automated RTP control strategies were installed at the Marriott Marquis Hotel in New York City, and field performance data were collected from mid-1993 through mid-1995. The results of this program indicate that automated RTP control strategies are feasible for achieving appreciable cost savings and load reductions without adversely affecting occupant comfort.
