The total hours of usage of a device in a day shall be computed by taking the cumulative sum of durations for which the device was in use for that day. The usage duration of a floor/zone/group shall be computed as the unique duration to which the devices have contributed such that the maximum usage duration computed for a floor/zone/group in an hour shall be 1 hour irrespective of the number of lights. For example, consider two devices D1 and D2 in a group/zone/building:
- If the 2 devices are used at the same time, say 10:00 to 10:30, the usage duration for the group/zone/floor the devices belong to shall be 30 min.
- If the 2 devices are used at the mutually exclusive time, say D1 is used from 10:00 to 10:30 (30 min) and D2 is used from 10:45 to 11:00 (15 min), the usage duration for the group/zone/floor the devices belong to shall be 45 min.
- If the 2 devices are used with an overlapping time, say D1 is used from 10:00 to 10:30 and D2 is used from 10:15 to 10:45, the usage duration for the group/zone/floor the devices belong to shall be 45 min.
