# Reduce Exterior Lighting Loads

## Description
This measure reduces exterior lighting loads by two ways: (1) upgrading the lighting fixtures to be more efficient, which reduces the design level value, (2) reducing operational durationand/or strength by adjusting control option and schedule based on daylight, occupancy, and/or user designated period.

## Modeler Description
This measure can (1) reduce design level by percentage if given by the user, (2) update the control option to AstronomicalClock, (3) adjust the schedule by replacing with occupancy schedule of the majority space/spacetype, and/or turn off or dim during user designated period.
