Where the occupancy density is known to be greater than 1 person/workspace per 10sqm, justification for the zones to be greater than every four workspaces, for example to fit with the adopted lighting strategy, is acceptable. The assessor must be satisfied that the aim of this criterion is upheld, i.e. that there is suitable zoning/control of lighting to enable a reasonable degree of occupant control over lighting in their personable work area. The relevant design team member, e.g. lighting consultant, should set out how this is to be achieved in such an instance.
