Abstract

Operating heating, ventilation, and air conditioning systems using occupancy sensing are described herein. One device includes instructions which cause a processor to receive building information including information defining a plurality of spaces of a building, occupancy sensing system information describing a location of each of a plurality of occupancy sensing system fixtures with respect to a representation of the building, and heating, ventilation, and air conditioning (HVAC) system information describing a relationship between the plurality of spaces and a plurality of HVAC devices installed in the building, create a mapping between a space of the plurality of spaces, a fixture of the plurality of fixtures, and an HVAC device of the plurality of HVAC devices based on the building information, and modify an operation of the HVAC device based on the mapping and responsive to a determination of occupancy in the space by the fixture.
