ENE 03 - External lighting

Information correct as of 18thOctober 2019. Please see kb.breeam.com for the latest compliance information.

Emergency lighting - KBCN0185

Maintained systems featuring emergency light fittings which are also used for normal operation, are assessed for this issue. Non-maintained lighting which is only activated in an emergency can be excluded from the assessment. The aim of this credit is to encourage and recognise external energy-efficient fittings. Non-maintained emergency lighting will very rarely be activated and in such extremes the emergency requirements must not be compromised.

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.

Night-time operation – requirement for controls - KBCN1048

Projects which operate at night-time can adapt or omit the requirement to provide controls or presence detection to align with the building’s hours of operation. The aim of this Issue is to reduce the energy use for external lighting and should not interfere with the building’s operation.

RGB LED lighting - KBCN0986

RGB LED lighting must be assessed against the average external lighting efficacy benchmark. The current criteria do not completely rule out the use of RGB LED lighting as it can potentially be combined with other types of external lighting to meet the average efficacy benchmark.
