  • Publication number: 20210229954
    Abstract: A system (100) for generating a thermal profile of a building is provided. The building includes an elevator (102) and a corresponding counterweight (103) within a hoistway (101). The system includes a facility management subsystem (130) and detection devices (136, 138). The facility management subsystem (130), in response to receiving an alarm, causes the elevator to automatically travel to one or more floors of the building and instructs the detection devices (136, 138) to collect images of one or more elevator lobbies of the building or the hoistway with respect to the elevator automatically traveling to the one or more floors. The facility management subsystem (130) generates a thermal profile based on the images.

  • Publication number: 20210201273
    Abstract: A system is provided that includes a memory system storing a plurality of executable instructions. The system also includes a processing system operably coupled to the memory system. The executable instructions when executed by the processing system cause the system to access a plurality of building structural data, ductwork layout data, and fire suppression system layout data associated with a building. A location of a user device within the building is identified. An overlay image is created that includes a three-dimensional depiction of a portion of a ductwork layout and a fire suppression system layout based on an overlay of the ductwork layout data and the fire suppression system layout data with respect to the building structural data and the location of the user device. The overlay image is output to a display component.
