Reduction of night time light pollution – Night-time operation - KBCN0697

Note: This KBCN supersedes INC 2016/INC V6 Pol 04 CN3.1  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.    
23 Jan 2023 - Note added to address conflict with INC Pol 04 CN3.1. KBCN title updated for consistency - The technical manual will be updated accordingly in the next re-issue
008 Mar 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.

Uniformity of illuminance (Table 57) - KBCN0600

The criteria for uniformity of illuminance (Table 57) has been removed from the issue as it is thought the criteria is not relevant to the international scheme. However, although table 57 was deleted in V1.0, the related criteria i.e 2a was not deleted. The amendment will be in place in the next re-issue of the manual.
Technical manual to be updated accordingly in next re-issue.
