Abstract: A method of updating building control system values includes instantiating a server object on a data server corresponding to a set of BCS values. The method also includes generating in a web server a data request associated with the server object and providing the data request to the data server. The method also includes providing a response to the data request if a change in at least one of the set of BCS values is acknowledged in the server object. The method further includes holding the data request open if no change in at least one of the set of BCS values is acknowledged and a predetermined time period has not elapsed since the data request was provided to the data server.

Abstract: A system and method for reducing an electrical load in a facility with a building automation system, includes first receiving information for a demand response event from an automated demand response server at an automated demand response client. After receipt of a new demand response event, the system determines a plurality of devices of the building automation system to be controlled during the demand response event. Next, the system prepares a schedule of control actions for the plurality of devices during the demand response event. The system then sends control messages to the building automation system to execute the control actions for the plurality of devices according to the schedule of control actions for the demand response event.

Abstract: A building system server includes a processing device executing a server program. The processing device receives a request from a remote device for information regarding a building control system. The processing device provides, responsive at least in part to the request for information, at least one software program. The remote device executes the software program to: request and receive background graphic data corresponding to the request; request and receive first data identifying at least one variable control, and a format of the at least one variable control; request and receive second data containing a building control value corresponding to the at least one variable control; and cause a compatible web browser to build a graphics page based on the graphic data, first data and second data. The processing device provides the graphics page to the remote device.

Abstract: A method of updating building control system values includes instantiating a server object on a data server corresponding to a set of BCS values. The method also includes generating in a web server a data request associated with the server object and providing the data request to the data server. The method also includes providing a response to the data request if a change in at least one of the set of BCS values is acknowledged in the server object. The method further includes holding the data request open if no change in at least one of the set of BCS values is acknowledged and a predetermined time period has not elapsed since the data request was provided to the data server.
