software and algorithms for fault detection and diagnosis that could be trained on data from the operating building. Then, under controlled circumstances, known faults would be induced in the system at planned points in time and member’s algorithms would attempt to detect and correctly diagnose the faults. Winners of the competition would be declared based on a scoring system that rewards both speed and accuracy of the diagnostic process. Potential Projects Using the Living Lab Contest to predict the second year’s While ASHRAE members anywhere in energy performance given the first year’s the world will be able to access detailed energy performance. Members would data on the operations of the headquarters compete to develop software and algorithms building, it will likely take some specific for predicting energy performance based on projects to help fully use the capabilities previous years’ measured data. Contestants of the facility. Members of the Technical would be provided with detailed operational Advisory Committee for the headquarters data for use in training algorithms and tools. renovation project have been working to These algorithms and tools would then be identify potential projects that might be used to predict a subsequent year’s perforlaunched in cooperation with the ASHRAE mance. Winners would be declared based on Electrical panels provide monitortechnical committees and the RAC. These a scoring system that rewards accuracy of ing of power and power factor for projects represent only a starting point for the prediction process. This contest would their circuits. ideas from the members. be similar in nature to the previous Great Contest to remotely detect and diagnose operational faults Energy Predictor Shootout3 conducted by ASHRAE technical with the building systems. Members would compete to develop committees. The enhancement in this contest compared to living lab data base resides. In addition, the new headquarters building’s controls system provides 24-hour data storage in field panels, which provides backup in the event of power outages. Users generally will have read-only access to the data and no access directly into the control system, unless arranged specifically in advance (e.g., for specifically approved purposes on a limited time basis as part of a research project).
