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.
