External lighting inside wider building - KBCN0906
Where a building undergoing assessment is located inside of another building, for example a retail unit within a shopping centre, Ene 03 External lighting and Pol 04 Reduction of night time light pollution should be assessed as follows;
Ene 03
'External lighting' that is inside of the wider building, using the example above the lighting is external of the retail unit itself but inside of the wider shopping centre, criteria relating to the luminous efficacy should be applied as presented within the manual. For the criteria relating to controlled for prevention of operation during daylight hours and presence detection in areas of intermittent pedestrian traffic, however, instead of demonstrating that the lighting is not operational during daylight hours, it should be demonstrated that the lighting is not operational outside of the operational hours of the wider shopping centre. Any external lighting within the scope of works being assessed that is located outside of the wider shopping centre, for example if the retail unit had an entrance or exit that leads on to the street outside, this would need to be assessed against the criteria presented within the manual.
Pol 04
If the building undergoing assessment has no external lighting that is outside of the wider building, it can be considered that the building has no external lighting. However, as above, any external lighting within the scope of works of the assessment that is located outside of the wider building will need to be assessed as the criteria is presented within the manual.

Security lighting - KBCN0915
The criteria generally apply to all external lighting, including security lighting. However, due to specific security requirements, there may be situations where a particular aspect of the criteria cannot be met, as they would compromise the development's security. For example, the use of PIR sensors may not be appropriate in high security developments, where continuous night-time CCTV surveillance is required.
In such cases, where this is justified by the security consultant or other appropriate member of the design team, compliance can demonstrated for the security lighting by meeting all other relevant criteria.
BREEAM does not seek to not impose requirements which could potentially compromise the development’s security strategy
10.03.2020 - KBCN amended following review. It has been determined that the criteria for this Issue must be applied to all security lighting, except as described above. KBCN no longer applicable to UK NC2011 as there is no criterion relating to PIR in this scheme.
