A processor-implemented method of controlling an HVAC system transforms a comfort map into a plurality of sequential constant-temperature segments that are used in generating a control temperature sequence that preserves occupant comfort while improving energy efficiency. The method balances user comfort, temperature trajectory execution complexity, operational HVAC trajectory realization, and energy efficiency. The system achieves this balance through utilization of comfort map metric data, analysis and control system execution. The system, comfort map metric data processing and analysis facilitates this balance by executing a control temperature sequence/temperature trajectories developed based on direct user comfort feedback data within the context of a comfort map and thermal equilibrium boundaries derived from the comfort map.

A system for allocating one or more resources including electrical energy across equipment that operate to satisfy a resource demand of a building. The system includes electrical energy storage including one or more batteries configured to store electrical energy purchased from a utility and to discharge the stored electrical energy. The system further includes a controller configured to determine an allocation of the one or more resources by performing an optimization of a value function. The value function includes a monetized cost of capacity loss for the electrical energy storage predicted to result from battery degradation due to a potential allocation of the one or more resources. The controller is further configured to use the allocation of the one or more resources to operate the electrical energy storage.

An air purifier (100) includes a detection unit (130) and a control unit (110). The detection unit (130) periodically detects environment information. The environment information indicates information relating to an environment around the air purifier (100). The control unit (110) determines whether or not the environment information satisfies a specific condition a plurality of times during the specific time period (Ts) corresponding to an event within a prescribed period (Ta). In a case where the control unit (110) determines that the environment information satisfies the specific condition a plurality of times, the control unit switches a mode from a learning mode to an implementation mode. In the implementation mode, in a case where the environment information meets a trigger during the specific time period, the control unit (110) performs event operational control.

An air flow control apparatus controls a fan. The air flow control apparatus includes an acquisition section, a detection section, and a control section. The acquisition section acquires image data obtained by an image capturing device installed in a target space. The detection section detects a specific object movable by an air flow sent from the fan, based on the image data acquired by the acquisition section. The control section executes first processing. The first processing includes controlling at least one of a direction and a volume of an air flow sent from the fan, based on a result of detection by the detection section.

Computer-implemented systems and methods for estimating a replacement status of an HVAC air filter. Outdoor weather data (e.g., outdoor temperature information), is obtained. A Total Runtime Value of the HVAC system is determined based upon the obtained outdoor weather data. Finally, a replacement status of the air filter is estimated as a function of a comparison of the Total Runtime Value with a Baseline Value. By correlating air filter replacement status with an estimated runtime of the HVAC system, a credible predictor of air filter usage is provided. By estimating fan runtime based on easily-obtained outdoor weather data, the methods are readily implemented with any existing HVAC system and do not require installation of sensors or other mechanical or electrical components to the HVAC system.

A method for relative temperature preference learning is described. In one embodiment, the method includes identifying one or more current settings of a thermostat located at a premises, identifying one or more current indoor and outdoor conditions, calculating a current indoor differential between the current indoor temperature and the current target temperature, calculating a current outdoor differential between the current outdoor temperature and the current target temperature, and learning temperature preferences based on an analysis of the one or more current indoor conditions and the one or more current outdoor conditions. The one or more current settings of the thermostat include at least one of a current target temperature, current runtime settings, and current airflow settings. The one or more current indoor and outdoor conditions include at least one of a current temperature, current humidity, current indoor airflow, current atmospheric pressure, current level of precipitation, and current cloud cover.

Systems and methods for integrating a building management system communicatively coupled to a security subsystem via a communication network, in which the building management system determines occupancy data, with a heating, ventilation, and air conditioning subsystem that includes a scrubber unit communicatively coupled to the building management system via the communication network. The scrubber unit includes a contaminant filter that sorbs air contaminants from a surrounding environment when an elevated pressure differential is introduced across the contaminant filter; an inlet sensor that determines sensor data indicative of contaminant level present in return air received by the scrubber unit from an internal portion of the building; and scrubber control circuitry that selectively instructs the scrubber unit to operate in one of multiple regeneration modes based at least in part on the occupancy data and the sensor data to facilitate improving filtering efficiency provided by the contaminant filter during subsequent operation.
