Abstract

An energy and facilities management system and method is provided for energy users with large physical plants which provides these energy users with a comprehensive understanding of the energy consumption of their physical plant and with the ability to manage it in a way that makes sense for their business. The system may include three dimensional facilities navigation tools, powerfill energy consumption analysis processes, TCP/IP communication capabilities and a World Wide Web (WWW)-based interface. The system also includes a real-time data retrieval and dissemination process and system which permits real-time energy data to be communicated within the system.

Claims

1. A system for managing the facilities and the energy consumption of an enterprise of an entity, the enterprise comprising one or more geographically dispersed facilities and buildings, each building and facility having one or more devices which operate and consume energy, the system comprising:

means for gathering information about the energy consumption and the operation of each device, wherein the gathering means further comprises a gateway device connected to one or more of the devices for gathering energy consumption and operation data about the device and for converting the energy consumption and operation data from a device format to a standard format;

an energy and facility management apparatus for controlling the facilities, buildings and devices in the geographically dispersed enterprise based on the energy consumption and operating information for each device, the energy management apparatus comprising means for communicating the energy consumption and operating data in real-time between the devices, the facilities and buildings and the energy and facility management apparatus, the energy and facility management apparatus further comprising a server for processing the standardized energy consumption and operation data about the devices from the gateway to generate energy consumption management and facility management data, a plurality of user interfaces connected to the server, each user interface requesting data about one or more devices in the physical plant, and a concentrator connected to one or more of the user interfaces for interfacing between the user interfaces and the server, the concentrator comprising means for registering requests for data from a particular device by a particular client application, means for combining requests for data from the same device into a single data request from the server in order to reduce the amount of data requests to the server; and

a user interface for requesting energy consumption and operation data about one or more devices, facilities or buildings and for viewing the energy consumption and operation data about a predetermined portion of the enterprise.

2. The system of claim 1 further comprising means for generating a representation of a particular selected facility in the enterprise based on the real-time energy consumption and operation data so that a user visually navigates through each facility.

3. A The system of claim 2, wherein the generating means comprises a two-dimensional navigator.

4. The system of claim 3, wherein the generating means comprises a three-dimensional navigator.

5. The system of claim 1 further comprising means for generating facility management data based on the energy consumption and operation data.

6. The system of claim 5 further comprising means for managing alarm signals generated by the facility manager and the energy manager in order to alert the user of the apparatus to alarm conditions in the geographically dispersed enterprise.

7. A method for managing the facilities and the energy consumption of an enterprise of an entity, the enterprise comprising one or more geographically dispersed facilities and buildings, each building and facility having one or more devices which operate and consume energy, the method comprising:

gathering information about the energy consumption and the operation of each device, the gathering further comprising gathering energy consumption and operation data about the device using a gateway device connected to one or more of the devices and converting the energy consumption and operation data from a device format to a standard format;

controlling the facilities, buildings and devices in the geographically dispersed enterprise based on the energy consumption and operating information for each device using an energy and facility management apparatus comprising communicating the energy consumption and operating data in real-time between the devices, the facilities and buildings and the energy and facility management apparatus, the controlling further comprising processing the standardized energy consumption and operation data about the devices from the gateway using a server to generate energy consumption management and facility management data, requesting data about one or more devices in the physical plant by a user interface, and interfacing between the user interfaces and the server using a concentrator connected to one or more of the user interfaces comprising registering requests for data from a particular device by a particular client application and combining requests for data from the same device into a single data request from the server in order to reduce the amount of data requests to the server;

requesting energy consumption and operation data about one or more devices, facilities or buildings using a user interface; and

viewing the energy consumption and operation data about a predetermined portion of the enterprise.

8. The method of claim 7 further comprising generating a representation of a particular selected facility in the enterprise based on the real-time energy consumption and operation data so that a user visually navigates through each facility.

9. The method of claim 8, wherein the generating comprises using a two-dimensional navigator.

10. The method of claim 8, wherein the generating comprises using a three-dimensional navigator.

11. The method of claim 7 further comprising generating facility management data based on the energy consumption and operation data.

12. The method of claim 11 further comprising managing alarm signals generated by the facility manager and the energy manager in order to alert the user of the apparatus to alarm conditions in the geographically dispersed enterprise.

13. A system for communicating data in real-time between an energy and facility management system and one or more devices of an enterprise which consume energy, the system comprising:

a device interface connected to the one or more of the devices for gathering real-time energy consumption data and operational data about the one or more devices connected to the device interface;

a server connected to the device interface for storing the energy consumption and operation data for each device in the enterprise into a database, the energy consumption and operation data for each device being identified by a unique device address;

a plurality of client applications, each client application requesting to receive energy consumption and operational data about one or more devices in the enterprise from the server; and

a concentrator connected between the server and the one or more client applications, the concentrator comprising means for analyzing the requests for data from the client applications, means for combining requests for energy consumption and operation data about a particular device into a single combined request, means for communicating the single combined request to the server, and means for routing the energy consumption and operating data about the particular device received from the server to each client application which requests the energy consumption and operation data about that particular device.

14. The system of claim 13 further comprising means for generating a representation of a particular selected facility in the enterprise based on the real-time energy consumption and operation data so that a user visually navigates through each facility.

15. The system of claim 14, wherein the generating means comprises a two-dimensional navigator.

16. The system of claim 14, wherein the generating means comprises a three-dimensional navigator.

17. The system of claim 13 further comprising means for generating facility management data based on the energy consumption and operation data.

18. The system of claim 17 further comprising means for managing alarm signals generated by the facility manager and the energy manager in order to alert the user of the apparatus to alarm conditions in the geographically dispersed enterprise.
