The key to achieving this credit is to find the optimum balance between lighting quality and lighting energy consumption. It is often assumed that more light is better, but a low level of uniform lighting throughout a site will eliminate the need to install bright halogen lamps that illuminate some areas and leave others dark in contrast.
For schools, the playground lights must turn off automatically after 11 p.m., with manual overrides available for special occasions. When designing exterior light-fixture layout, locate light fixtures as far from site boundary as possible.
The lighting designer develops a photometric study for exterior lighting intensity, the impact of shades and cutoff fixtures, and light trespass from the project boundary. Use the photometric study to inform any changes in the design.

The lighting designer includes the design intent in Basis of Design for EAp1: Fundamental Commissioning, for all outside lighting requirements, listing minimum
Identify the project location and IESNA-designated zone to determine the threshold for exterior lighting levels. Utilize resources like the website www.citydata.com to identify relevant population density and appropriate designation.
