System for optimising workflow for efficient on-site data collection and determination of energy analysis and method of operation thereof

1. An energy audit system for use in retrofitting energy consuming devices in an energy consuming space, comprising:

at least one controller configured to:

obtain attribute information (AI) for the energy consuming devices, the AI comprising information related to a plurality of attributes and corresponding attribute choice information for each of the plurality of attributes;

determine dependencies between each of the plurality of attributes to each determine a dependency score for each of the plurality of attributes based on the determined dependencies;

determine a ranking of each of the attributes based upon the dependency score of each of the attributes;

select a subset of the plurality of attributes based on the ranking;

determine an optimized workflow based upon the subset of the plurality of attributes; and

in accordance with the optimized workflow, render a user interface (UI) for use in retrofitting at least one of the devices to thereby obtain energy savings;

wherein said retrofitting comprises at least one of replacing a lighting fixture and replacing a lighting control device.

2. The system of claim 1 , wherein the controller further is configured to obtain attribute choice information selected by a user and which corresponds to at least one of the subset of the plurality of attributes.

3. The system of claim 1 , wherein the controller is configured to determine the dependencies of each of the plurality of attributes to each other of the plurality of attributes by constructing a dependency matrix.

4. The system of claim 1 , wherein the controller is configured to compare the dependency score of the plurality of attributes to a threshold value, wherein the subset of the plurality of attributes is selected as ones of the plurality of attributes with a dependency score that meets or exceeds the threshold value.

5. The system of claim 4 , wherein the controller is configured to automatically populate attribute choice information corresponding to at least one of the subset of the plurality of attributes that is determined to be a dependent attribute.

6. A method of generating an energy audit for use in retrofitting energy consuming devices in an energy consuming space, the method performed by at least one controller and comprising acts of:

obtaining attribute information (AI) for the energy consuming devices, the AI comprising information related to a plurality of attributes and corresponding attribute choice information for each of the plurality of attributes;

determining dependencies between each of the plurality of attributes to each other;

determining a dependency score for each of the plurality of attributes based on the determined dependencies;

determining a ranking of each of the attributes based upon the dependency score of each of the attributes;

selecting a subset of the plurality of attributes based on the ranking;

determining an optimized workflow based upon the subset of the plurality of attributes; and

in accordance with the optimized workflow, rendering a user interface (UI) for use in retrofitting at least one of the devices to thereby obtain energy savings;

wherein said retrofitting comprises at least one of replacing a lighting fixture and replacing a lighting control device.

7. The method of claim 6 , further comprising an act of obtaining attribute choice information selected by a user and which corresponds to at least one of the subset of the plurality of attributes.

8. The method of claim 6 , further comprising an act of determining the dependencies of each of the plurality of attributes to each other of the plurality of attributes by constructing a dependency matrix.

9. The method of claim 6 , further comprising an act of comparing the dependency score of the plurality of attributes to a threshold value, wherein the act of selecting the subset of the plurality of attributes comprises an act of selecting ones of the plurality of attributes with a dependency score that meets or exceeds the threshold value.

10. The method of claim 9 , farther comprising an act of automatically populating attribute choice information corresponding to at least one of the subset of the plurality of attributes that is determined to be a dependent attribute.

11. A computer program stored on a non-transitory computer readable memory medium, the computer program configured to generate information indicative of an energy audit for use in retrofitting energy consuming devices in an energy consuming space, the computer program comprising:

a program portion configured to:

obtain attribute information (AI) for the energy consuming devices, the AI comprising information related to a plurality of attributes and corresponding attribute choice information for each of the plurality of attributes;

determine dependencies between each of the plurality of attributes to each other;

determine a dependency score for each of the plurality of attributes based on the determined dependencies;

determine a ranking of each of the attributes based upon a dependency score of each of the attributes;

select a subset of the plurality of attributes based on the ranking;

determine an optimized workflow based upon the subset of the plurality of attributes; and

in accordance with the optimized workflow, render a user interface (UI) on a display of the system for use in retrofitting at least one of the devices to thereby

obtain energy savings;

wherein said retrofitting comprises at least one of replacing a lighting fixture and replacing a lighting control device.
