Abstract: A method for determining a measure of thermal energy delivered via a VAV box includes receiving an AHU supply air temperature, a VAV discharge air temperature, a space air temperature, and a VAV discharge flow rate. The measure of thermal energy delivered by the VAV box to the space during the first period of time is determined based at least in part on three or more of the received parameters. The determined measure of thermal energy delivered by the VAV box and a determined measure of thermal energy delivered by each of a plurality of other VAV boxes of the facility are aggregated over the first period of time, resulting in an aggregated measure of thermal energy. This may be used to adjust one or more control parameters to achieve a desired balance of energy consumption versus comfort, energy and/or health.

Abstract: Implementations described and claimed herein provide systems and methods for evaporative cooling control. In one implementation, a humidity setpoint is received for a designated space, and at least one atmospheric condition of ambient air is received. The at least one atmospheric condition is measured using one or more ambient air sensors. A performance prediction of an evaporative cooler is generated by calculating a set of one or more predicted psychrometric properties of supply air leaving the evaporative cooler based on the at least one atmospheric condition. The humidity setpoint is compared to the set of one or more predicted psychrometric properties of the performance prediction in a setpoint comparison. A flow of fluid is controlled over evaporative media using one or more pumps of the evaporative cooler. The flow of the fluid is controlled based on the setpoint comparison such that the humidity setpoint is prevented from being exceeded.

Abstract: A system and method for crowd-sourced environmental system control and building maintenance includes a server for providing selective access to building occupants and managers. Users are permitted to generate building reports in the form of (i) thermal reports using a thermal report module, and/or (ii) maintenance reports using a maintenance report module. The reports are each geo-located to locations within the building, and are then captured, stored, and aggregated at the server. The aggregated reports are sorted according to their geo-locations and comfort rules are used to (i) permit a manager at a client computer to access the server to respond, and/or (ii) automatically respond and assign a response status to particular reports. An inspection checklist interface is generated and populated to display a list of preventative maintenance tasks, each of the tasks being user-selectable to designate completion, with the updated status of the reports being stored at the server.

Abstract: A fan includes a hub, several fan blades, and a motor that is operable to drive the hub. A motor controller is in communication with the motor, and is configured to select the rate of rotation at which the motor drives the hub. The fan is installed in a place having a floor and a ceiling. An upper temperature sensor is positioned near the ceiling. A lower temperature sensor is positioned near the floor. The temperature sensors communicate with the motor controller, which includes a processor configured to compare substantially contemporaneous temperature readings from the upper and lower temperature sensors. The motor controller is thus configured to automatically control the fan motor to minimize the differences between substantially contemporaneous temperature readings from the upper and lower temperature sensors. The fan system may thus substantially destratify air in an environment, to provide a substantially uniform temperature distribution within the environment.

Abstract: A system including a processor and sensor for installation inside an underground vault. The sensor monitors a parameter inside the vault and sends a monitoring signal to the processor. Based on the monitoring signal, the processor may provide data to a memory for storage and/or control signals to an interface for transmission to an external device located within the vault. The control signals instruct the external device to modify the environment inside the vault. The sensor may be positioned inside an enclosure, which is inside a housing. An air moving device moves air into or out of the enclosure thereby drawing air from the vault into the enclosure before the sensor monitors the parameter. A heat generating component may be positioned inside the housing and when generating heat prevents moisture from condensing therein. The system may include a power unit that draws power from a power source inside the vault.
