This report documents work performed for ASHRAE 1146-RP, entitled Building Operation and Dynamics within an Aggregated Load. Research was done in two phases. Tasks undertaken as part of Phase I involved (1) an extended background and historical perspective on electric utility aggregation, (2) a description of various candidate sites where load aggregation programs have been implemented and clearly recorded, (3) a detailed description of each of three case-study sites where load aggregation and subsequent energy management strategies were performed, and (4) a summary of the lessons learned from the above case studies.

The case studies revealed that the motivation for aggregating multiple buildings under the current state of affairs was essentially energy-cost related (i.e. better rates could be negotiated because of the larger aggregated load). Very little was being done in terms of load control in either individual buildings or in aggregated buildings.

The second phase of the work consisted of the development of a list of 11 tools that could be used by aggregators and their customers to alter the operation of buildings to control load."
