Abstract: A thermal optimization control includes processing circuitry. The processing circuitry is operable to receive information from a building housing at least one computer server, with the information including at least current thermal load. The processing circuitry is operable to control an associated HVAC system for at least an area of the building where the at least one computer server is housed. The processing circuity is operable to optimize the operation of the HVAC system based upon the current and an expected upcoming thermal load on the area of the building where the server is received to reduce energy usage by the HVAC system. A method and building are also disclosed.

Abstract: Embodiments of the disclosure describe systems and methods for detecting an occupancy of a room. The method comprises receiving, from a plurality of sensors located within the room, sensor readings indicative of corresponding occupancy parameters. The plurality of sensors are configured to measure the corresponding occupancy parameters. The method further comprises determining, based on the received sensor readings, one or more of an occupancy status of the room, and a confidence value associated with the determined occupancy status. The occupancy status is indicative of one of a positive status indicating occupancy of the room and a negative status indicating non-occupancy of the room. The method further comprises, in response to determining the occupancy status, triggering a control action associated with the room based on the determined occupancy status.

Abstract: A heating ventilation and air conditioning (HVAC) system includes an air handling unit having an outlet, at least one zone operably coupled to the outlet of the air handling unit, and at least one indoor air quality sensor operable to monitor an amount of one or more contaminants. The at least one indoor air quality sensor is arranged within the at least one zone. A controller operably coupled to the at least one indoor air quality sensor is configured to detect the occurrence of a fault or an unsatisfied indoor air quality condition and perform diagnostics to determine the cause of the fault or the unsatisfied indoor air quality condition.

Abstract: A heating ventilation and air conditioning (HVAC) system includes an air handling unit having an outlet, at least one zone operably coupled to the outlet of the air handling unit; and at least one indoor air quality sensor operable to monitor a level of one or more contaminants. The at least one indoor air quality sensor is arranged within the at least one zone. A controller operably coupled to the at least one indoor air quality sensor and is configured to determine when an amount of the one or more contaminants within the at least one zone exceeds an allowable threshold and implement a multi-level ventilation strategy to reduce the amount of the one or more contaminants within the at least one zone to below the allowable threshold.

Abstract: An elevator system (20) uses destination entry dispatching techniques. A passenger interface device (22) operates in a first mode to allow passengers (24) to enter destination requests for elevator service. The passenger interface (22) operates in a second mode to provide at least one additional feature to an authorized individual. The additional feature may be at least one of a service-related function, a security-related function, a monitoring-related function or a communication-related function.

Abstract: A position reference system for use with a conveyance, such as an elevator (12). The system includes a code affixed to or embedded within a suspension device or primary motion coupling such as a rope or coated steel belt (16). A reader (28) in a fixed location determines the position of the conveyance.
