Abstract

The present disclosure relates to determining one or more of a space occupancy score, space energy score, and space efficiency score for a collection of lighting endpoints in a lighting network. The space occupancy score is indicative of how effective the occupancy groups are configured for a given space or the utilization level for a space. The space energy score is indicative of how much energy the collection of lighting endpoints use or will likely use based on their configurations, actual use, or a combination thereof. The space efficiency score is indicative of the overall efficiency associated with the collection of lighting endpoints based on both occupancy and energy related metrics.

First claim

What is claimed is:

1. A computing device to associate with a lighting network having a plurality of lighting fixtures grouped into a plurality of occupancy groups, the computing device comprising:
a communication interface;
a memory; and
a processor device coupled to the memory and the communication interface to:
for each occupancy group of the plurality of occupancy groups:
receive at least one occupancy parameter for an occupancy group;
receive at least one energy consumption parameter for the occupancy group; and
generate a space efficiency score based on both the at least one occupancy parameter and the at least one energy consumption parameter; and

provide for presentation to a user the space efficiency score for at least one of the plurality of occupancy groups.

2. The computing device of claim 1 wherein, for each occupancy group, the at least one occupancy parameter allows the processor device to determine a number of the plurality of lighting fixtures in the occupancy group, such that the space efficiency score is a function of the number of the plurality of lighting fixtures in the occupancy group.

3. The computing device of claim 1 wherein the at least one occupancy parameter allows the processor device to determine a number of the plurality of lighting fixtures that detect activity when any of the plurality of lighting fixtures in the occupancy group detect the activity, such that the space efficiency score is a function of the number of the plurality of lighting fixtures that detect the activity when any of the plurality of lighting fixtures in the occupancy group detect the activity.

4. The computing device of claim 3 wherein, for each occupancy group, the at least one occupancy parameter allows the processor device to determine a number of the plurality of lighting fixtures in the occupancy group, such that the space efficiency score is a function of the number of the plurality of lighting fixtures in the occupancy group and the number of the plurality of lighting fixtures that detect the activity when any of the plurality of lighting fixtures in the occupancy group detect the activity.

5. The computing device of claim 4 wherein the space efficiency score is a function of:
a ratio of a number of the plurality of lighting fixtures in the occupancy group that detect the activity to the number of lighting fixtures in the occupancy group; and
the number of the plurality of lighting fixtures in the occupancy group.

6. The computing device of claim 4 wherein:
the at least one energy consumption parameter includes a static setting of one or more lighting fixtures in the occupancy group, and the static setting is at least one of a task tuning level and an auto-off level of the one or more lighting fixtures in the occupancy group; and
the at least one energy consumption parameter is indicative of an actual light output level of the one or more lighting fixtures in the occupancy group based on at least one of user input via a wall controller and daylight harvesting data provided by the one or more lighting fixtures in the occupancy group.

7. The computing device of claim 4 wherein:
the at least one energy consumption parameter includes static settings of one or more lighting fixtures in the occupancy group, and the static settings include a task tuning level and an auto-off level of the one or more lighting fixtures in the occupancy group; and
the at least one energy consumption parameter is indicative of an actual light output level of the one or more lighting fixtures in the occupancy group based on user input via a wall controller and daylight harvesting data provided by the one or more lighting fixtures in the occupancy group.

8. The computing device of claim 3 wherein:
the at least one energy consumption parameter includes a static setting of one or more lighting fixtures in the occupancy group, and the static setting is at least one of a task tuning level and an auto-off level of the one or more lighting fixtures in the occupancy group;
the at least one energy consumption parameter includes a dynamic setting indicative of an actual light output level of the one or more lighting fixtures in the occupancy group based on at least one of user input via a wall controller and daylight harvesting data provided by the one or more lighting fixtures in the occupancy group.

9. The computing device of claim 1 wherein the at least one energy consumption parameter includes a static setting of one or more lighting fixtures in the occupancy group, and the static setting is at least one of a task tuning level and an auto-off level of the one or more lighting fixtures in the occupancy group.

10. The computing device of claim 1 wherein the at least one energy consumption parameter is indicative of an actual light output level of one or more lighting fixtures in the occupancy group.

11. The computing device of claim 10 wherein the actual light output level is controlled by user input via a wall controller.

12. The computing device of claim 10 wherein the actual light output level is controlled in response to daylight harvesting data provided by the one or more lighting fixtures in the occupancy group.

13. The computing device of claim 1 wherein the processor device is further configured to determine a modification to make to the at least one of the plurality of occupancy groups based on the space efficiency score, and present the modification to the user, wherein the modification either adds or removes a lighting fixture from the at least one of the plurality of occupancy groups.

14. The computing device of claim 1 wherein the processor device is further configured to determine a modification to make to the at least one of the plurality of occupancy groups based on the space efficiency score, and present the modification to the user, wherein the modification changes a setting for a lighting fixture in the at least one of the plurality of occupancy groups.

15. The computing device of claim 1 wherein the processor device is further configured to determine a modification to make to the at least one of the plurality of occupancy groups based on the space efficiency score, and communicate with at least one lighting fixture in the at least one of the plurality of occupancy groups to effect the modification, wherein the modification either adds or removes a lighting fixture from the at least one of the plurality of occupancy groups.

16. The computing device of claim 1 wherein the processor device is further configured to determine a modification to make to the at least one of the plurality of occupancy groups based on the space efficiency score, and communicate with at least one lighting fixture in the at least one of the plurality of occupancy groups to effect the modification, wherein the modification changes a setting for a lighting fixture in the at least one of the plurality of occupancy groups.

17. The computing device of claim 1 wherein a first space is associated with at least two of the plurality of occupancy groups and the processor device is further configured to:
generate an aggregated space efficiency score based on the space efficiency score for the at least two of the plurality of occupancy groups; and
present the aggregated space efficiency score for display to the user.

18. The computing device of claim 1 wherein the processor device is configured to present the space efficiency score for each of the plurality of occupancy groups for display to the user, such that each space efficiency score is associated with a unique iden
