Exterior lighting generally operates from early evening through early morning, a period of little to no renewable energy generation, which means this lighting is primarily powered by carbon-dense fossil fuels. Fossil fuel use is a significant contributor to greenhouse gas emissions (GHG), poor air quality, water pollution and land degradation. In addition, low-quality exterior lighting characterized by poor color, inappropriate light distribution, and inadequate light levels has also been linked to increased crime rates and reduced physical activity within the surrounding community.
PIER sponsored research, development, and demonstration (RD&D) has focused on the combination of occupancy-based lighting controls and dynamically turnable light sources to create intelligent, bi-level luminaires for parking area applications.
The PIER Program sponsored development of the adaptive LED bollard, an innovative technology designed to combat the energy wasted on overlighting unoccupied urban spaces. To successfully reduce energy consumption and provide dynamic light levels to the surrounding environment, project partners selected long-life light emitting diodes (LED) and fixture-integrated occupancy sensors to create a unique adaptive bollard. This combination delivers long life, low-energy consumption, and dynamic light output based on occupancy.
CLTC – The California Lighting Technology Center (CLTC), a research, development, and demonstration facility at the University of California, Davis, has installed more than 100 demonstrations of energy-efficient lighting since the Center’s inception in 2004. The wide range of demonstrations has been installed at University of California, California State University, California Community College campuses, and state and federal buildings throughout California in an effort to prove energy-efficient technology and report the findings to the public through case studies.
