Advanced Lighting Controls for Reducing Energy Use and Cost in DoD Installations

Energy consumption in DoD installations consisting of 2.2 billion sq. ft. of building space is a major concern due to cost of energy, nearly $4 billion annually, as well as resulting carbon emission. Lighting is one of the most pervasive energy consuming elements present in these installations and also impacts the load of HVAC systems due to heat generation. Therefore reducing lighting related energy consumption by means of advanced lighting control strategies including occupancy sensing, light tuning, daylight harvesting and proper lighting design is an effective way to increasing the energy efficiency of the installations. To demonstrate this and quantify the energy savings possible with advanced lighting controls system, Philips in partnership with Lawrence Berkeley National Laboratories has carried out a demonstration project deploying three lighting control system solutions in three chosen buildings in Fort Irwin, California over a period of nearly two years. The results have shown 43-78% lighting energy savings relative to a 1989 Code Baseline and as much as 15% savings in HVAC loads due to advanced lighting controls. This report describes the details of this project and the results obtained.
