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 during the report period. After revising the prototype days based on the PMS comments, we rebuilt 8 Excel files with detailed control strategies of thermal cooling and heating setpoints, chilled water setpoints, and supply air temperature adjustment. Preliminary simulations have been completed. We expect to complete all required simulations in the next quarter. Then we will start to write a final.
