This research project is funded by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE), and is sponsored by ASHRAE Technical Committee (TC) 7.5: Smart Building Systems. The objective of this project is to identify and evaluate peak demand reduction strategies formulated in response to short notification of critical peak rates and time-of-use charges from utilities, for use in commercial buildings. Ever increasing pressure on utilities has resulted in pricing forecasts that are on the order of hours instead of days, and previously researched strategies like pre-cooling of building thermal mass will not be as useful in reducing peak load when the demand on the grid is at its highest. To overcome this limitation, strategies specific to short-term electrical price forecasts will be investigated and identified.This quarterly report presents the continuous work as a part of Task 4: Simulation and presentation of results. It also includes the FSEC presentation and the meeting minutes in the research meeting with PMS members in Albuquerque on June 28, 2010.
