Abstract: Sensorized commercial buildings are a rich target for building a new class of applications that improve operational and energy efficiency of building operations that take into account human activities. Such applications, however, rarely experience widespread adoption due to the lack of a common descriptive schema that would enable porting these applications and systems to different buildings. Our demo presents Brick [4], a uniform schema for representing metadata in buildings. Our schema defines a concrete ontology for sensors, subsystems and relationships among them, which enables portable applications. Using a web application, we will demonstrate real buildings that have been mapped to the Brick schema, and show application queries that extracts relevant metadata from these buildings. The attendees would be able to create example buildings and write their own queries.

Abstract: A method for monitoring or controlling equipment of a building includes receiving a first timeseries comprising first data samples of a first variable monitored or controlled by a system and a second timeseries comprising second data samples of a second variable monitored or controlled by the system. The first data samples are at least partially asynchronous with the second data samples. The method includes synchronizing the first timeseries with the second timeseries by aggregating both the first timeseries and the second timeseries using equivalent aggregation intervals. Aggregating the first timeseries generates a third timeseries comprising aggregated values of the first variable and aggregating the second timeseries generates a fourth timeseries comprising aggregated values of the second variable. The method includes performing an automated operation to monitor or control the equipment of the building using the synchronized data samples of the third timeseries and the fourth timeseries.
