Abstract

A building automation system (BAS) includes building equipment located within a building and a BAS network configured to facilitate communications between the building equipment. The building equipment operate to affect a variable state or condition within the building. The BAS includes a BAS-BIM integrator configured to receive BAS points from the BAS network and to integrate the BAS points with a building information model (BIM). The BIM includes a plurality of BIM objects representing the building equipment. The BAS includes an integrated BAS-BIM viewer configured to use the BIM with the integrated BAS points to generate a user interface. The user interface includes a graphical representation of the BIM objects and the BAS points integrated therewith.

Dependent claims

A building automation system (BAS) comprising:

building equipment located within a building, wherein the building equipment operate to affect a variable state or condition within the building;
a BAS network configured to facilitate communications between the building equipment;
a BAS-building information model (BIM) integrator configured to receive BAS points from the BAS network and to integrate the BAS points with a BIM comprising a plurality of BIM objects representing the building equipment, the BAS-BIM integrator comprising:
a BAS tree generator configured to generate a BAS tree comprising the BAS points;
a BIM tree generator configured to generate a BIM tree comprising the BIM objects;
and
a mapping interface generator configured to generate a mapping interface comprising the BAS tree and the BIM tree;
an integrated BAS-BIM viewer configured to use the BIM with the integrated BAS points to generate an integrated BAS-BIM user interface comprising a graphical representation of the BIM tree and a graphical representation of the BIM objects and the BAS points integrated therewith, with the BAS points shown in graphical association with the BIM objects;
and
an alarm manager that receives an alarm from the BAS network, associates the alarm with one of the BIM objects, causes the alarm to be displayed via the integrated BAS-BIM user interface, and causes a graphical representation of the BIM object associated with the alarm to be displayed via the integrated BAS-BIM user interface in response to receiving a selection of the alarm via the integrated BAS-BIM user interface;
wherein the integrated BAS-BIM viewer is configured to display a graphical representation of one of the BIM objects in response to receiving a selection of the one of the BIM objects via the graphical representation of the BIM tree.

8 more elements

A system for integrating building automation system (BAS) points with a building information model (BIM), the system comprising:

a BAS-BIM integrator configured to receive BAS points from a BAS network and to integrate the BAS points with a BIM comprising:
a three-dimensional model of a building;
and
a plurality of BIM objects representing building equipment;
the BAS-BIM integrator comprising:
a BAS tree generator configured to generate a BAS tree comprising the BAS points;
a BIM tree generator configured to generate a BIM tree comprising the plurality of BIM objects;
and
a mapping interface generator configured to generate a mapping interface comprising the BAS tree and the BIM tree;
an integrated BAS-BIM viewer configured to use the BIM with the integrated BAS points to generate an integrated BAS-BIM user interface comprising a graphical representation of the BIM including the three-dimensional model of the building, the BIM objects, and the BAS points integrated therewith, and a graphical representation of the BIM tree for switching between a plurality of different views of the graphical representation of the BIM, the plurality of different views of the graphical representation of the BIM comprising at least a perspective view of the graphical representation of the BIM and a front view of the graphical representation of the BIM;
the integrated BAS-BIM viewer configured to:
present the integrated BAS-BIM user interface on a single window with the BAS points shown in graphical association with the BIM objects,
receive a selection of a selected BIM object,
display, in response to receiving the selection of the selected BIM object, a selected BAS point associated with the selected BIM object, and
switch between the plurality of different views of the graphical representation of the BIM in response to receiving a user selection of the graphical representation of the BIM tree;
an alarm manager that receives alarms from the BAS network, associates the alarms with BIM objects, and causes the alarms and the associated BIM objects to be displayed via the integrated BAS-BIM user interface.
