Abstract: A bi-level optimization scheduling method for an air conditioning system based on demand response includes: constructing a lumped heat capacity model to describe a heat storage capacity of a building to thereby obtain a building heat storage model; obtaining a function relational expression of describing an indoor dry bulb temperature and a cooling and heating load of the building based on the building heat storage model; constructing a power consumption calculation model under a working condition of demand response based on the function relational expression; constructing optimization objective functions based on the power consumption calculation model; and substituting the optimization objective functions into a bi-level optimization process, and optimizing the bi-level optimization process to obtain an optimal scheduling strategy for the air conditioning system participating in demand response. The method can achieve a global optimization of demand response scheduling strategy, and improve economy and energy saving of system operation.

Abstract: A facility providing systems and methods for managing and optimizing thermal comfort is provided. The facility is a software algorithm that intelligently detects the thermal comfort preferences of residential smart thermostat users, where a user's “comfort preference” is defined to refer to an estimate of a measurement of the user's comfort across varying values of some set of exogenous factors, including but not limited to indoor temperature, the time of day, the day of the week, and weather conditions. This facility encompasses the use of this “comfort preference” for the creation of an optimal schedule of setpoints for a residential thermostat which is configured to optimize some objective, including potentially user comfort, energy efficiency, load shift, or cost.

Abstract: A system includes a processing circuit configured to provide an energy use setpoint based on energy data including an energy characteristic and subject to a constraint based on a variable condition of a building. The processing circuit is configured to estimate a value for the energy use setpoint that will result in the variable condition of the building satisfying the constraint and provide a control signal for equipment based on a difference between the energy use setpoint and a measured energy use.

Abstract: Architectures or techniques are presented that can prioritize operating a consumption device in a manner that is efficient in terms of consumption of a resource over satisfying a specified demand assigned to the consumption device. This re-prioritizing can be performed in response to a price of the resource exceeding a threshold.

Abstract: Described herein are techniques for optimizing operation of a refrigerant climate control system using an energy management device. In an example process, the energy management device may receive an energy optimization signal that describes a characteristic associated with an electrical energy source. The process may also include the energy management device generating a control signal for a refrigerant climate control system to use the electrical energy source based at least in part on the characteristic of the energy optimization signal. The process may also include the energy management device providing the control signal to a controller of the refrigerant climate control system.

Abstract: An air conditioning system is provided, which includes a transfer fan for transferring air to a room as a space in a house from an air-conditioned room, a motion sensor for detecting whether the room is occupied or unoccupied and an air conditioning system controller for controlling the transfer fan. In the air conditioning system, a target air conditioning environment obtaining section obtains at least a target air conditioning environment of the room, an occupied-room air conditioning environment section controls the transfer fan that transfers air to the occupied room to approximate the occupied room to the target air conditioning environment according to information from the motion sensor and an unoccupied-room air conditioning environment section controls the transfer fan that transfers air to the unoccupied room to approximate the unoccupied room to a quasi-target air conditioning environment where an energy burden is lower than that of the occupied room according to information from the motion sensor.

Abstract: In a commercial building, individual occupant thermal comfort is achieved with optimal cost and energy efficiency through the integration of a variety of local thermal comfort components into a communication network that employs emerging optimization principles to meet individual preferences for the thermal environment on a workstation basis while reducing building energy use and operating in accordance with any constraints on the energy grids that serve the buildings. These multiple objectives are met in part through a robust communication network that employs distributing processing to achieve preferred thermal conditions with optimal control of all components at subzone, zone, system, central plant, and energy grid levels.

Abstract: A system, method and apparatus for remote control of a thermostat by a network-based server, when the thermostat is not connected to a local or wide-area network. A network-based server calculates a modified temperature profile for a thermostat based on a utility's time-of-use pricing and/or weather forecasts. After the server has calculated the modified temperature profile, it is provided to a mobile device via a wide-area network, and the mobile device provides the modified temperature profile directly to the thermostat when the mobile device is within range of the thermostat.

Abstract: Appropriate ventilation for a building space while maintaining building comfort includes tracking one or more interior environmental conditions within the building space and one or more exterior environmental conditions outside of the building space during operation of the HVAC system. An environmental model for the building space is learned over time based at least in part on these tracked environmental conditions, where the environmental model predicts an environmental state of the building space in response to operation of the HVAC system under various interior and exterior environmental conditions. A maximum allowed ventilation rate that can be achieved without causing the HVAC system to compromise on any of one or more comfort conditions of the building space is predicted using the environmental model. The outdoor air ventilation damper of the HVAC system is then controlled to provide an appropriate ventilation up to or at the predicted maximum allowed ventilation rate.
