Replace the entire first paragraph with the following, "All nonemergency interior lighting fixtures with a direct line of sight to any openings in the envelope must be automatically controlled and programmed to turn off or have their input power reduced by at least 50% between 11 p.m. and 5 a.m. Controls can be automatic sweep timers, occupancy sensors, or programmed master lighting control panels. The design can also include manual or occupancy based override capabilities that enable lights to be turned on after hours."
