California Outdoor Lighting Baseline Assessment

Report / January 21, 2010 / Codes And Policy

This is the first major study to provide real data about commercial building outdoor lighting in the State of California. The report identifies statewide outdoor lighting design practices; estimates energy demand and consumption; and provides a framework for outdoor lighting standards in California and future investigations of outdoor lighting.


This report contains data collected from visits to over 300 sites throughout California, encompassing 20 different categories of businesses as well as multifamily residential buildings. Data includes lighting power density (LPD) levels by functional use area (parking lots, walkways, facades, etc.); types of lamps and fixtures at each site; illuminance levels; glare and light trespass readings; and use of lighting controls.
