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

The massive footprint of mostly old building stock in the Department of Defense s DoD inventory offers significant opportunities for reducing energy consumption, carbon emissions, and operating costs. Existing lighting systems in many DoD facilities consume excessive electrical energy because they are often outdated, inefficient, and lack automated controls. These factors result in increased energy consumption, higher operational, maintenance, lifecycle costs, and reduced workforce productivity. Therefore, the intent of this project is to retrofit buildings with advanced lighting control systems that combine dimmable light sources, occupancy and daylight sensors, and intelligent controls to significantly lower the lighting energy consumption as well as reduce cooling loads due to the thermal effects of lighting. Furthermore, appropriate control and monitoring systems can lower maintenance cost and improve occupant satisfaction. The DoD s Environmental Security Technology Certification Program ESTCP commissioned a team consisting of Philips and Lawrence Berkeley National Laboratory LBNL to study the performance of advanced lighting control systems in DoD buildings. Philips developed and deployed the lighting control systems and LBNL carried out the evaluation of energy savings and occupant surveys by collecting pre- and post- retrofit data and performing all the data analysis.
