Abstract: A building heating, ventilation or air conditioning (HVAC) system is shown. The system includes a display device. The display device includes a first processing circuit, the first processing circuit provides a setpoint to one or more virtual controllers. Execution of one of the one or more virtual controllers with the setpoint of an environmental condition of the building generates one or more control commands. The processing circuit further provides the one or more control commands to a building equipment. The system further includes the building equipment that receives the one or more control commands to control the environmental condition of the building.

Abstract: A method for providing environmental comfort includes obtaining measurements of a dry bulb temperature, a relative humidity, and an airflow rate for an indoor space, calculating an apparent temperature for the indoor space using the measurements, and generating a visualization comprising a comfort band and a value of each of the apparent temperature, the dry bulb temperature, the relative humidity, and the airflow rate for the indoor space plotted relative to the comfort band along independent axes. The method also includes controlling building equipment to drive the value of one or more of the apparent temperature, the dry bulb temperature, the relative humidity, or the airflow rate into the comfort band.

Abstract: A building management system includes a plurality of devices of building equipment and a system manager. The system manager is configured to control the devices of building equipment and generate a user interface. The user interface includes a command widget configured to allow a user to input a first command to control a first device of the plurality of devices of building equipment and an add annotation box configured to allow a user to add an annotation to the command. The system manager is further configured to control the first device in response to the command and store the annotation in an annotation database.

Abstract: An HVAC system for a building includes an airside economizer, a plurality of sensors, and a controller. The airside economizer includes a first air intake configured to receive return air from within a building, a second air intake configured to receive outdoor air from outside the building, and an air discharge configured to provide discharge air to the building. The controller is configured to identify a wet coil condition or a dry coil condition, calculate an enthalpy of the return air and an enthalpy of the outdoor air, select either a normal cooling mode or free cooling mode based on the calculated enthalpy of the return air, the calculated enthalpy of the outdoor air, and the identification of the wet coil condition or the dry coil condition, operate the airside economizer to provide the return air to the building as the discharge air in response to selecting the normal cooling mode, and operate the airside economizer provide the outdoor air to the building as the discharge air in response to selecting the free cooling mode.

Abstract: A facility management portal and associated user interface can be used for remote monitoring, servicing, and commissioning of a Building Management System (BMS) and associated devices. Building stakeholders can use the facility management portal to configure smart thermostat devices with various settings or parameters associated therewith. For example, building stakeholders may create device profiles associated with smart thermostat devices and provide different device profiles to different groups of thermostat devices installed in a building. Moreover, stakeholders can use the facility management portal to monitor data such as energy consumption and air quality associated with buildings. Building tenants can interact with control devices such as smart thermostats and associated mobile applications to initiate maintenance or emergency notifications relayed through the facility management portal.

Abstract: The present disclosure is directed to a method for managing energy consumption of one or more building equipment devices. The method includes identifying a building equipment device. The building equipment device may serve at least one portion of a physical premise. The method includes retrieving a first set of data including specifications of the building equipment device. The method includes retrieving a second set of data including an occupancy schedule of the at least one portion of the physical premise for a first period of time. The method includes retrieving a third set of data including weather conditions around the physical premise for the first period of time. The method includes predicting, based on the first, second, and third sets of data, energy consumption of the building equipment device for a second period of time, which can allow a user to adjust a working schedule of the building equipment device.
