A number of lighting manufacturers now produce LED replacement lamps for traditional 60W incandescent lamps, and stakeholders at the state and national levels face decisions regarding quality standards for this product category. To assist these stakeholders and assess the current state of this segment of the lighting market, CLTC performed photometric and electrical tests on samples of 26 commercially available A19 and A21 omnidirectional LED replacement products.
This work will discuss the CALCTP program, its energy savings potential, the challenges in educating an established trade group in new technology, programs stemming from the initial CALCTP effort, and the immediate need for ongoing support to ensure this model program continues to succeed in the coming years. Presented by Cori Jackson at the American Council for an Energy-Efficient Economy (ACEEE) Conference 2012.
Street lights with controls systems offer dynamic dimming during long periods of inactivity, a feature with tremendous potential to save energy, mitigate waste, reduce light pollution, and increase public safety. In spite of all these advantages, there is no nationwide control standard established to date, and LED street lights are being installed en masse without this important feature. These fixtures are likely to be in use for as long as 20 years, so the fixed-wattage, un-retrofittable fixtures sold today represent a significant loss in long-term savings opportunity.
The retail sector constitutes one of the largest energy consumers in the U.S., and halogen parabolic aluminized reflector (PAR) and multifaceted reflector (MR) lamps are common retail lighting choices. LED replacement lamps have the potential to transform lighting energy use in this sector, and manufacturers of LED PAR and MR lamps now claim comparable photometric performance, as well as much greater longevity, than traditional halogen lamps.
Lighting accounts for about a quarter of California’s electricity use, and installing energy-efficient lighting can lead to significant energy, maintenance, carbon, and economic savings, according to the California Public Utilities Commission (CPUC). In September 2010, the CPUC adopted a plan to achieve a 60–80% reduction in statewide electrical lighting consumption by 2020.
Demonstrations on UC and CSU campuses have proven that SPEED technologies offer reliable, cost-effective solutions for achieving deep energy savings. Effective July 1, 2014, many SPEED technologies will be required under California’s 2013 Title 24 Building Energy Efficiency Standards.
The primary objective of this study is to quantify the energy use in private offices that are equipped with bi-level switching and occupant controls. The baseline comparison is made to a theoretical case where the occupant has no control over their lighting and it is switched on and off solely by an occupancy sensor. In addition, this study looks closely at the possibilities for combining automatic and manual control to achieve the greatest energy savings and user satisfaction.
The CLTC’s objective is to produce a group of products, technologies, and knowledge that meets PIER goals of improving energy cost and value by developing energy-efficient lighting technologies and bringing them to market through research, development, outreach, and technology transfer activities. Twenty-four projects are listed in the new agreement, including topics in daylighting, solid-state lighting, and market transformation. This report gives abbreviated summaries of these projects.
This document provides overviews of state-of-the-art commercial, residential, and exterior lighting strategies and technologies followed by detailed analysis that demonstrates the significant energy or electricity savings potential of several of these best-practice alternatives.
