All external lighting within the construction zone, whether retained without alterations, retained with alterations or newly specified, must meet the requirements of Ene 03 and Pol 04.

Even if new proposed lighting meets compliance, the existing lighting fixtures could have a high energy demand and result in night-time light pollution.
