  • Publication number: 20190032948
    Abstract: A building management system includes a remote rules server and a local rules server. The local rules server is located at a customer site, and includes a standard rules database and a custom rules database. The standard rules database stores standard rules and the custom rules database stores user-created rules. The local rules server is configured to allow a customer to create a new user-created rule and send the new user-created rule to the remote rules server. The remote rules server is configured to receive the new user-created rule and provide the new user-created rule to one or more other local rules servers located at one or more other customer sites.

  • Publication number: 20190033811
    Abstract: A building management system includes a meter configured to collect meter data. The building management system also includes a data analytics center, an interface generator, and a dynamic linking system. The data analytics center is configured to receive the meter data from the meter, associate the meter data with a space; and apply the meter data as an input to an algorithm to generate a metric related to the space. The interface generator is configured to generate a user interface that allows a user to add or delete a link between the meter and the space. The dynamic linking system is configured to dynamically alter the algorithm to include or exclude the meter data when generating the metric related to the space in response to the user adding or deleting the link between the meter and the space via the user interface.

  • Publication number: 20190033803
    Abstract: A building management system includes building equipment, a metric generation system, and a visualization engine. The building equipment is configured to generate data samples. The metric generation system is configured to collect the data samples and generate key performance indicators. The visualization engine is configured to create a scorecard that displays the key performance indicators. The scorecard comprises a building energy overview widget that displays total consumption of a building, a consumption by space widget that displays consumption of a plurality of subspaces of the building, and a consumption by commodity widget that displays consumption of the building categorized by commodity. In some embodiments, the scorecard also includes an energy density by space widget that displays consumption per unit area per day for the subspaces of the building.

  • Publication number: 20190034309
    Abstract: A building management system includes a plurality of devices of building equipment configured to provide status data. The building management system also includes an equipment management server configured to assign and store parent-child relationships for the plurality of devices of building equipment. The equipment management server is also configured to monitor the status data to detect faults and generate a fault visualization interface. The fault visualization interface provides provide a list of the devices with detected faults, allows a user to select one or more of the devices from the list, and presents a parent-child relationship widget for the selected device. The parent-child relationship widget includes a list of parent devices for the selected device and a list of child devices for the selected device. Each device on the lists of parent devices and child devices has a status indicator indicating whether the device is in a fault condition.

  • Publication number: 20190025809
    Abstract: A building management system for monitoring equipment status is provided. The building management system includes a processing circuit configured to generate one or more diagnostics for a piece of building equipment based on one or more faults. The processing circuit is further configured to generate a work order based on the one or more diagnostics. The processing circuit is further configured to cause the work order to include task details for resolving the one or more faults. The task details are based on the one or more diagnostics associated with the one or more faults.

  • Publication number: 20190025776
    Abstract: A building management system for monitoring equipment status is provided. The building management system includes a processing circuit configured to generate one or more constants for a piece of building equipment based on thresholds and device specific templates. The constants are equation based relationships between a value and a threshold. The processing circuit is further configured to generate one or more sub-rules based on the one or more constants and one or more equipment points. The sub-rules are equation based relationships between the one or more constants and the one or more equipment points. The processing circuit is further configured to generate a rule based on the one or more sub-rules and the one or more equipment points. The rule is an equation based relationship between the one or more sub-rules and the one or more equipment points and indicates whether the piece of building equipment is experiencing a fault.
