# Groups

Groups allow you to set a hierarchy and prioritise specific Zones you wish to report. You can create as many Groups as you like, adding Zones to a Group to report at the Group level. The example below explains the concept of Groups, where Unit 1 is identified as the Group of Zones on which you wish to report Daylight Factor results.
