Abstract

A software module for a building automation system includes a plurality of software modules. A first module is configured to compute energy consumption characteristics of a building. A second module is configured to determine at least one alternate hardware configuration for the building, and to provide an estimated performance level associated with each of the at least one alternate hardware configuration. A third module is configured to recommend one of the at least one hardware configurations based on at least one predetermined financial criteria.

Claims

1. A performance analysis module for a building automation system used to control a building comprising:

a first system configured to compute a plurality of performance level characteristics based on an existing building equipment configuration of a building;

a second system configured to determine at least one alternate building equipment configuration for the building, and an estimated performance level characteristic associated with the at least one alternate building equipment configuration; and

a third system configured to recommend one of the existing building equipment configuration or the at least one alternate building equipment configurations based on at least one predetermined financial criteria associated with at least one of the plurality of performance level characteristics.

2. The module of claim 1, also comprising a fourth system configured to order building equipment from a predetermined supplier based upon the recommended existing or alternate building equipment configuration.

3. The module of claim 2, wherein the fourth system is also configured to arrange financing through the supplier.

4. The module of claim 3, wherein the fourth system is also configured to schedule a service technician of the supplier to install newly ordered building equipment.

5. The module of claim 1, wherein the first system computes the plurality of performance level characteristics based on at least one actual energy consumption measurement associated with the building.

6. The module of claim 5, wherein the at least one actual energy consumption measurement associated with the building is derived from at least one standard power measurement device.

7. The module of claim 6, wherein the at least one standard power measurement device is selected from the group consisting of electric power meters, energy meters, voltage and current measuring devices, and combinations thereof.

8. The module of claim 1, wherein the first system includes performance level characteristics based on at least one estimated energy consumption parameter associated with the building.

9. The module of claim 8, wherein the at least one estimated energy consumption parameter is based on one of empirical data, fundamental models, correlations, performance maps, and combinations thereof.

10. The module of claim 1, wherein the second system determines the at least one alternate building equipment configuration for the building, and the estimated performance level is based on a plurality of building parameters.

11. The module of claim 10, wherein the building parameters include at least one selected from the group consisting of building size, seasonal heating and cooling loads, occupancy, usage, climate and energy profile characteristics associated with the building.

12. The module of claim 10, wherein the at least one alternate building equipment configuration comprises at least one selected from the group consisting of variable speed drives, an air handling unit, a chiller system, cooling towers, pumps, packaged rooftop units and combinations thereof.

13. The module of claim 10, wherein the estimated performance level is computed based on one or more of empirical data, fundamental models, correlations, or performance maps.

14. The module of claim 10, wherein the second system includes a database of HVAC equipment components, the HVAC equipment components being inter-compatible and capable of forming a working HVAC system.

15. The module of claim 10, wherein the second system applies at least one building type input selected from a plurality of predetermined building types.

16. The module of claim 10, wherein the second system is configured to divide the building into a plurality of building types to account for varying loads within the building.

17. The module of claim 1, wherein the building performance characteristics also include an acoustic performance factor or an indoor air quality (IAQ) factor, and building equipment recommendations for acoustic performance or IAQ are based on a cost per dBa relative to the acoustic performance factor, or on a cost per unit of CO2 for the IAQ factor.

18. A computer program product embodied on a computer readable medium and executable by a microprocessor for selecting building equipment components for minimum energy consumption in a building automation system, the computer program product comprising computer instructions for executing the steps of:

computing energy consumption characteristics based on an existing building equipment configuration of a building;

determining at least one alternate building equipment configuration for the building;

providing an estimated performance level associated with the at least one alternate building equipment configuration; and

recommending one of the existing building equipment configuration or the at least one alternate building equipment configurations based on at least one predetermined financial criteria.

19. The computer program product of claim 18, further comprising computer instructions for executing the steps of:

accessing an Internet connection between a building equipment equipment supplier and a BAS end-user

based on the recommended building equipment configuration, providing the BAS end-user with prices on building equipment products in the recommended building equipment configuration via the Internet connection.

20. The computer program product of claim 19, further comprising computer instructions for executing the steps of:

scheduling a service technician of the building equipment supplier for installing a building equipment product; and

obtaining financing through the building equipment supplier.

21. A method of selecting building equipment components for minimum energy consumption in a building automation system, comprising computing energy consumption characteristics based on an existing building equipment configuration of a building;

determining at least one alternate building equipment configuration for the building;

providing an estimated performance level associated with the at least one alternate building equipment configuration; and

recommending one of the existing building equipment configuration or the at least one alternate building equipment configurations based on at least one predetermined financial criteria.

22. The method of claim 21, also including the steps of:

accessing an Internet connection between a building equipment equipment supplier and a BAS end-user based on the recommended building equipment configuration, providing the BAS end-user with prices on building equipment products in the recommended building equipment configuration via the Internet connection.

23. The method of claim 22, also including the steps of:

scheduling a service technician of the building equipment supplier for installing a building equipment product; and

obtaining financing through the building equipment supplier.
