Abstract
A building management system and method that determines space utilization in a building. The building management system comprises room utilization sensors, such as occupancy sensors, a gateway that gathers raw occupancy data records from the occupancy sensors, and at least one processor. Each raw occupancy data record comprises an occupancy state associated with a timestamp. The processor is configured for normalizing the raw occupancy data records into normalized occupancy data records each comprising a time segment and an occupancy state indicating whether for a given time segment a room is occupied. The processor is further configured for structuring the normalized occupancy data records by associating each normalized occupancy data record with a space node corresponding to a room in the building from where the raw occupancy data record was collected and associating each space node with a set of tags, each tag defining a single state from a plurality of states. The processor may further receive a selection of a tag from a user interface, split the normalized occupancy data records along the selected tag's states into sets of normalized occupancy data records, for each split set …
