A thin form of an electrical connector for creating a detachable connection between two circuit elements is disclosed. When the connector is employed, only an outer electrode present on a portion of the connector is exposed to the ambient environment and the rest of the electronics of both the connector and of a device into which the device is integrated can be insulated from the ambient environment. The parts of the connector can create a small three-dimensional interlock structure to seal off contact area and to facilitate electrical contacts between two circuit elements. The connector structure is flexible, allowing the connector to be embedded into a curved surface of a device that can use the electrode exposed to the environment to obtain data regarding the environment.

A physics model of a building is linearized around an operating point. Measurements received from sensors define a system state of the HVAC system. The linearized physics model is used as an equality constraint for a model predictive controller that determines a next control input to the HVAC system based on the system state by solving an optimization problem for a time horizon of size N. A constraint matrix H of the equality constraint is decomposed into factors of U and V matrices such that UUand VV are both diagonal matrices. An objective function of the model predictive controller is optimized by iteratively solving a linear system of equations that includes inverses of UUand VV to determining a sequence of inputs for a horizon of the model predictive controller. A first input of the sequence of inputs to is used to control the HVAC system.

Methods and systems to commission building environmental sensors are disclosed. The system includes a device that will move about the environment of a building (inside and/or outside) and detect building environmental sensor devices that are installed in the environment. For each of the sensor devices, in response to detecting the sensor device, the system will retrieve an identifier for the sensor device, and it will determine whether the sensor device is registered with a control system. If the sensor device is registered with the control system, the system will not automatically implement a commissioning process with the sensor device. If the sensor device is not registered with the control system, the system will automatically implement the commissioning process with the sensor device.
