NSW J7D3 Artificial lighting2019: J6.2

Delete subclause J7D3(2) and insert NSW J7D3(2) as follows:

(2) In a Class 3 or Class 5 to 9 building—

  1. for artificial lighting, the aggregate design illumination power load must not exceed the sum of the allowances obtained by multiplying the area of each space by the maximum illumination power density in Table J7D3a; and
  2. the aggregate design illumination power load in (a) is the sum of the design illumination power loads in each of the spaces served; and
  3. where there are multiple lighting systems serving the same space, the design illumination power load for (b) is—
    1. the total illumination power load of all systems; or
    2. where a control system permits only one system to operate at a time based on the highest illumination power load; or determined by the formula—
