A Building Management System (BMS) may be controlled in accordance with predicted occupancy using a trained model. A model is trained by providing the model with time stamped environmental data and corresponding time stamped occupancy data pertaining to a training building, wherein the time stamped environmental data is derived from one or more environmental sensors of the training building and the corresponding time stamped occupancy data is derived from one or more occupancy sensors of the training building. Once trained, the trained model is provided with time stamped environmental data for a use building that is derived from one or more environmental sensors of the use building. The trained model outputs a predicted occupancy value that represents a predicted occupancy count in the use building, and the BMS of the use building is controlled based at least in part on the predicted occupancy value.

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.

A system reduces risk of pathogen exposure within a space that is located within a facility having a plurality of spaces that periodically have one or more people within the space. The system includes one or more occupancy sensors that are configured to provide an indication of when the space is occupied and when the space is not occupied. A sanitizer is configured to sanitize surfaces within the space when activated. A controller is operably coupled with the one or more occupancy sensors and the sanitizer. The controller is configured to determine a designated time to sanitize the space based at least in part upon information received from the one or more occupancy sensors and to automatically instruct the sanitizer to sanitize surfaces within the space at the designated time.

An adaptor plate includes a front plate that is configured to span across at least a portion of a front of an electrical junction box and includes one or more adaptor plate mounting features configured to align with corresponding mounting features of the electrical junction box. A DIN rail engagement portion extends backward from the front plate (and into the junction box) and is configured to fit at least partially into an elongated DIN rail mounting recess of a DIN rail device. In some cases, a first mounting slot is disposed within a first side of the DIN rail engagement portion for receiving a first mounting latch of the DIN rail device, and a second mounting slot is disposed within a second side of the DIN rail engagement portion for receiving a second mounting latch of the DIN rail device.

A computer system provides a method for analyzing various parameters, variables and/or conditions associated with the operation of HVAC systems. Some example computer systems display a coordinate system with multiple graphs of variables and conditions having disparate units of measure, such as degrees Centigrade, percent, ppm, on/off, etc. In some examples, variables and conditions with similar units of measure are grouped together. The groups of similar units are plotted along different segments of the coordinate system's y-axis. The segments and their respective graphs of similar units are distributed vertically, one above the other. All of the graphs, however, share a common x-axis, which is labeled in units of time. This makes it easier to visually compare multiple, disparate variables and conditions at particular points in time. When an HVAC related problem occurs, the visual comparisons can help identify the problem and its source.
