Abstract: A control system includes one or more sensors configured to generate sensor data relating to building equipment. The sensor data includes first sensor data collected during a first time period and second sensor data collected during a second time period. The control system also includes a controller configured to use the first sensor data to generate one or more first model coefficients for a model for the building equipment. The controller is also configured to use the second sensor data to generate one or more second model coefficients for the model, generate a test statistic by comparing the one or more first model coefficients and the one or more second model coefficients, compare the test statistic with a value, and automatically identify a change relating to the building equipment in response to the test statistic exceeding the value.

Abstract: A system for controlling temperature of a building space includes HVAC equipment configured to serve the building space, a plurality of sensors configured to measure a plurality of parameters relating to the building space, and a control system. The control system is configured to receive data from the plurality of sensors, generate a plurality of disturbance heat flow estimates for the building space based on the data from the plurality of sensors, determine a feedforward heat flow contribution based on the disturbance heat flow estimates, determine a feedback heat flow contribution based on a measured temperature of the building space and a temperature setpoint for the building space, combine the feedforward heat flow contribution and the feedback heat flow contribution to determine a rate of heat flow to be provided to the building space by the HVAC equipment, and control the HVAC equipment to provide the rate of heat flow.

Abstract: Systems and methods for providing visualization of health risks within a building. Health risk levels for building spaces are determined using occupancy data and health risk data relating to a risk of contracting or spreading an infectious disease. A visualization of the health risk levels is generated and presented on a user interface.
