scope:

This Standard specifies performance requirements for artificial lighting in large buildings to achieve an adequate level of energy efficiency.

This Standard applies to large buildings that have artificial lighting. The lighting power density limits may be applied to any large building.

NOTE - Regulation may make compliance with this Standard mandatory for certain classes of large building.

This Standard provides a method of demonstrating compliance. This power density limits method applies a limit to the power density of the fixed lighting for each area of a building depending on the spatial function of that area.
