Laboratory Evaluation of DC Lighting Systems

Historically, power distribution has been dominated by Alternating-Current (AC) which significantly influenced the design of connected energy-consuming appliances. With the emergence of electronics and digital controls as standard design elements in almost all appliance categories, the need for Direct-Current (DC) has emerged, even as it opposes traditional distribution practices. This issue is typically resolved at the appliance level with AC-to-DC converters.

Residential Lighting Technology Webinar

Interested in the current state of residential lighting products? CLTC recently presented on linear LED lamp technologies as part of a webinar panel focused on light sources for the residential market. The webinar was conducted in support of Bonneville Power Administration and can be revisited here.

Educational Video Series: 2016 Lighting Controls Technologies & Requirements

08/10/2017

The California Lighting Technology Center (CLTC) at the University of California Davis collaborated with the California Energy Commission to provide this educational video series in support of the 2016 Building Energy Efficiency Standards (Title 24). Sensors and controls can achieve significant energy savings by automatically adjusting lighting based on time of day, available task needs, daylight, occupancy, and electricity supply or cost.

Title 24: Residential Lighting

The Residential Lighting Design Guide outlines best practices in lighting design to help builders comply with California's 2019 Title 24 Energy Standards requirements.

Topics include:

Explanation of the code
Technical and compliance information
Lighting design examples

The lighting design guide will cover code explanation and floor plan examples of the following areas:

Title 24: Office Lighting

This Office Lighting course is designed for those who design, specify, or inspect lighting installations in new and remodeled commercial office spaces. The curriculum includes an overview of current lighting technologies, including LED luminaires, and updates on new lighting requirements and sections in the 2019 standards.

Learning outcomes for course participants include the ability to:

Nonresidential Lighting and Electrical Power Distribution Guide for 2016 Building Energy Efficiency Standards

03/13/2017

The California Lighting Technology Center’s 2016 Nonresidential Lighting and Electrical Power Distribution Guide assists builders and lighting industry professionals in navigating the nonresidential lighting portion of California’s Building Energy Efficiency Standards (Title 24, Part 6). California's new nonresidential Building Energy Efficiency Standards took effect on January 1, 2017.

Lighting Fact Sheets for 2016 Building Energy Efficiency Standards

02/23/2017

The California Lighting Technology Center has developed a series of fact sheets designed to raise awareness of the 2016 Building Energy Efficiency Standards, which took effect on January 1, 2017. These materials are intended to increase knowledge and implementation of code-compliant lighting for California’s residential and non-residential buildings.

Available fact sheets focus on key areas of the Energy Standards including:

Integrated Building Control Retrofit Package for Commercial Applications

The California Lighting Technology Center, in collaboration with the California Energy Commission, is conducting research to develop and evaluate technology that integrates automated controls for heating, ventilating and air conditioning (HVAC), electric lighting and dynamic fenestration systems. The integrated system is referred to as the Integrated Building Control Retrofit Package (IBCRP), as it is aimed for retrofit projects in existing commercial buildings.

Linear LED Lamps: Application and Interoperability Evaluation

CLTC collaborated with the Emerging Technologies group at the Pacific Gas & Electric Company to evaluate linear LED lamps in a variety of fixture applications as well as identify any interoperability issues.

New Generation of LED Lighting Systems

Widespread adoption of LED lighting for general illumination applications is poised to be the single, largest advancement in lighting efficiency during the 21st century. Due to its potential, a variety of market actors have introduced LED products and made associated performance claims that have set the technology up with somewhat unrealistic expectations regarding system efficacy and longevity. To compete in this market, LED manufacturers have focused on research to improve efficacy and reduce product costs, often at the expense of product quality and feature optimization.
