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.
The California Lighting Technology Center (CLTC) at the University of California Davis collaborated with the California Energy Commission to provide educational video series and lighting fact sheets in support of the 2016 Building Energy Efficiency Standards (Title 24). Videos and fact sheets cover four key topics:
Lighting Controls Technologies & Requirements
High-Efficacy Lighting for Residential Applications
Lighting Alterations and Additions
Lighting Controls Acceptance Testing
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.
The California Energy Commission adopted new standards updating the Appliance Efficiency Regulations (Title 20) for lighting appliances. Updates rolled out in two tiers with Tier 1 effective January 1, 2018 and Tier 2 effective July 1, 2019. Notably, this update adds standards for small-diameter directional lamps. The updated regulations incorporate elements of lighting product quality for both general service LED lamps and small-diameter directional lamps in addition to the traditional lighting appliance efficiency standards previously included in the regulations.
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.
CLTC, in collaboration with the Office of Naval Research, developed new, improved strategies and technologies for occupancy sensing in outdoor applications that address the shortcomings of existing strategies and technologies. The project approach included the systematic identification of the pros and cons of existing strategies and technologies, formulation of new strategies and/or technologies, and implementation of new approaches in the form of laboratory prototypes that will be tested and demonstrated in the laboratory and in the field.
CLTC, in partnership with Southern California Edison, completed a project portfolio from 2014-2018 to assess controls, lighting, and daylighting technologies and their potential for commercial applications. The projects have elements of market assessment, EM&V, and selected demonstrations.
The project focus is on evaluating the following technologies:
Advanced lighting control systems (ALCS) 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.
