Principle Where:

• The scope of assessment covers no occupied spaces and,
• There is no valid way to filter credits from that issue,

Credits specifically related to occupied space are not awarded. Outcome The tables below show how this principle applies to affected issues.

• Y means all credits are available (unless the comments state otherwise). Standard filtering rules still apply, so some credits can be filtered out where allowed in the criteria.
• N means all credits in the issue cannot be awarded. These credits are not filtered out.

Zoning and occupant control – access to lighting controls - KBCN00032

The relevant areas for the criteria apply only to areas where users are expected to have control. For instance, this means that areas intended for the general public, or a shop floor would not be expected to have lighting controls. The general principle which applies to user access to general environmental controls (heating, cooling, ventilation) may also apply to access to lighting controls. See KBCN0170. However, the the exact approach may differ between the two types of systems and assessor judgement must be used to determine compliance. In all cases zoning is required in all areas of the asset where specified in the assessment criteria. Please refer to the specific requirements of the applicable BREEAM standard to interpret this guidance appropriately.

14-Dec-2022 - KBCN applicability updated to include BIU. Wording updated. Link to KBCN0170 created.

Zoning and occupant control – whiteboards and display screens - KBCN1433

Whiteboards and display screens in dedicated teaching or presentation spaces require separate zoning and control for lighting, as specified in the criteria. Lighting around whiteboards and display screens which are typically found in general office areas, meeting rooms, or in other generic spaces do not require separate zoning and control to meet the criteria. In such cases, the assessor should provide justification. Whiteboards and display screens in dedicated teaching / presentation spaces are likely to be used frequently, and require appropriate zoning and control. An increasing number of offices and meeting rooms now include display screens - however separate zoning and control may not be appropriate.
