Amendment 1 includes updates to the lighting power density limits (LPDLs) of the standard, and other subsequent areas of the standard that relate to the updated LPDLs, the terminology and definitions to align with current accepted practices, and removal of all references to the calculation method within the standard. The calculation method determined a limit to the power of the fixed lighting for a whole building on the maintained illuminance recommended for the purposes of each area within the building; this method is no longer used in current practice.
