Occupancy estimation based on multiple sensor inputs

A system for controlling one or more components of a Building Management System (BMS) of a building in accordance with an estimated occupancy count of a space of the building, the system comprising:

• a plurality of occupancy sensors each for monitoring an occupancy count of the space of the building;
• a controller operatively coupled to the plurality of occupancy sensors, the controller configured to:
• identify an error parameter for each of the plurality of occupancy sensors, each error parameter representative of a difference between the occupancy count of the respective occupancy sensor and a ground truth occupancy count of the space, normalized over a period of time;
• determine an assigned weight for each of the plurality of occupancy sensors based at least in part on the respective error parameter;
• determine the estimated occupancy count of the space of the building based at least in part on:
• the occupancy count of each of the plurality of occupancy sensors;
• the assigned weight of each of the plurality of occupancy sensors;
• and
• control the BMS based at least in part on the estimated occupancy count.

A non-transitory computer-readable storage medium having stored thereon instructions that when executed by one or more processors cause the one or more processors to:

• access a trained model that is trained to predict an occupancy count of a space of a building using time stamped occupancy data from a number of different occupancy sensors and corresponding time stamped ground truth occupancy data;
• predict an occupancy count of the space of the building by:
• providing the trained model with time stamped occupancy data pertaining to the space of the building from each of the number of different occupancy sensors;
• the trained model outputting an estimated occupancy value that represents an estimated occupancy count in space of the building;
• and
• control a BMS of the building based at least in part on the estimated occupancy value.
