Immediately Scalable Sensing in Buildings

Estimate the sensor data of one building based on sensor data collected in other buildings. The basic premise is that common design and construction patterns for buildings create a repeating structure in their sensor data. Read More

Automatic Metadata Mapping for Scalable Building Analytics

Create a suite of automated mapping solutions that will allow an analytics engine to quickly connect to and analyze the data from an unfamiliar building. This research enables building analytics to be applied at scale. Read More
