2015 Lighting Technology Overview

2015 Lighting Technology Overview

The 2015 Lighting Technology Overview (LTO) provides overviews of commercial and residential lighting technologies and strategies with the potential to significantly reduce California’s lighting energy use. The guide includes information on expected energy savings, factors to consider when comparing products, sample products, and case studies for indoor and outdoor lighting and controls technologies. Products in the guide include:

Advanced Lighting Control Systems: Bench Testing


Advanced lighting control systems provide networked control and monitoring capabilities of connected luminaires via onboard metering and system reporting features.  These advanced features allow system owners to dynamically balance visual comfort and lighting energy use.  CLTC, in collaboration with SDG&E, developed a technology validation program to determine the accuracy and reliability of onboard metering and system reporting features of advanced lighting control systems.

IES LD+A Research Matters: Defining Accuracy - Energy Use Reporting through Lighting Control Systems


One of the promises of networked lighting controls is to monitor energy use over time and adjust the system to achieve the best possible performance.  Facility managers can match the reporting to expectations and change settings to capture maximum savings.  The promise of real-time energy monitoring has also piqued the interest of utility program managers in locations in the U.S. where rebates assist with the accelerated adoption of emerging technologies. 

Liberty Lighting Guidelines for Zero Net Energy Communities

Liberty Lighting Guidelines for Zero Net Energy Communities

CLTC is partnering with Liberty to create a zero net energy community in West Sacramento along the Sacramento River. The Liberty Lighting Guide provides design and technical specifications, application of directives, as well as Title 24 code compliance requirements for residential, outdoor, private community clubhouses, K – 8 schools, private clubhouses, neighborhood commercial spaces, parks, greenbelts, trails, sports, and recreation centers.

LD+A Research Matters: Adaptive Lighting for Retail Environments


The retail sector, which represents 13 percent of California's commercial lighting electricity use, has historically not embraced the use of lighting controls.  Reasons for this are many including perceived high cost, system complexity, and the potential for negative impacts on customers and sales.  California building lighting energy efficiency standards for the retail sector have a higher lighting power density allowance and fewer requirements for mandatory controls in sales areas than other commercial and industrial building space types.
