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.

Missing criterion – external lighting standards - KBCN0883

The following criterion, included in the BREEAM INC 2013 scheme, was omitted in error from the BREEAM IRFO 2015 and BREEAM INC 2016.
  1. The external lighting strategy has been designed in compliance with the limits set for light technical parameters in section 2.7 of CIE 150-2003 and table 2 of CIE 126-1997.
Projects registered after the announcement of this KBCN in the July 2017 Process Note must comply with this and other relevant criteria within Pol 04 in order to achieve the credit.
Technical manual to be updated accordingly in next reissue.

Night-time operation - KBCN0697

During hours of operation between 23:00 and 07:00, lighting required for operational reasons does not have to be modified for BREEAM compliance. The aim of this Issue is to reduce light pollution by automatically switching off the external lighting or by complying with lower levels when the building is not in use.
08/03/2018 Wording amended to add clarity.

Safety and security lighting – definition - KBCN0888

BRE does not provide a specific definition of safety and security lighting, as this could vary, depending on the project and location of the lighting. Together with the design team, the assessor is required to determine which lights are provided purely for safety and security purposes and which should be considered as general lighting.
