    Abstract: Methods and systems for operating a Heating, Ventilating and Air Conditioning (HVAC) system in accordance with one of a plurality of operating modes. The plurality of operating modes include one or more of a health mode, an energy savings mode and a balanced mode. In some cases, the operating modes include two or more energy saving modes. The currently operating mode is selected based on the current operating conditions of the building and the desired goals of the building operator. The goals can include, for example, reducing energy usage, reducing pathogen risks, increasing air quality and/or a combination of these goals. In some cases, the operating modes are autonomously controlled. In some cases, the operating modes are manually controlled.

    Abstract: Devices, systems, and methods for providing fire events pattern analysis and cross-building data analytics are described herein. One fire system maintenance system, includes a number of fire system detectors, a fire system control panel, and a gateway device all positioned within the facility, the gateway device having instructions to: collect fire system device health data associated with one or more fire or smoke detector devices and to send this fire system device health data to a remote device, the remote device having instructions to: analyze the collected fire system device health data to determine an event type for each device health event recorded in the collected data, predict future device health events, categorize the device health events based on their determined event type, and prioritize the categorized device health events based on the quantity of events categorized in each event type.

    Abstract: Controlling a fresh air intake includes determining a fresh air intake damper position based on the supply air flowrate, a measure of energy delivered to the supply air flow, or a measure of humidity of the supply air flow. Determining the fresh air intake damper position is subject to a constraint that the AHU maintains one or more comfort conditions in the building space and one or more of a constraint regarding maintaining one or more Indoor Air Quality (IAQ) contaminants in the building space below one or more IAQ thresholds, minimizing energy consumption of the AHU, and maximizing the fresh air ventilation air flow into the building space. Various parameters used to determine the fresh air intake damper position may be derived from available sensed conditions so as to reduce the number of physical sensors that are required.
