The California Lighting Technology Center’s Residential Lighting Guide assists builders and lighting industry professionals in navigating the residential lighting portion of California’s Building Energy Efficiency Standards (Title 24, Part 6 or Energy Code). The 2019 iteration of the Energy Code took effect on January 1, 2020.
The CLTC is excited to announce a new publication in our Lighting Best Practices series, the Daylight Harvesting for Commercial Buildings Guide! This publication provides guidance towards meeting and exceeding California's Building Energy Efficiency Standards for daylight harvesting.
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:
The lighting design guide will cover code explanation and floor plan examples of the following areas:
The California Energy Alliance (CEA) unites representatives of a broad range of organizations concerned about energy and the built environment. As a member-based organization, CEA works to improve California’s energy future and the migration toward a Zero Net Energy horizon. CEA focuses on the promotion and realization of deep energy savings, sustainable energy generation, and integration. The Alliance actively participates in the development and implementation of pragmatic, environmentally and economically sound building energy standards and other initiatives.
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:
CLTC is supporting the Center for Sustainable Energy develop classroom and on-the-job workforce training in SB 535-designated disadvantaged communities in IOU service territories. This project is funded by the California Energy Commission.
Electrical apprentices will learn to install and maintain automated demand-response (ADR) communications equipment in existing buildings to improve grid reliability and advance to goals of AB 758. Specifically, CLTC's role in the project is to:
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.
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.
The potential to reduce energy consumption in existing and commercial buildings is enormous. On average, 30% of the energy used in commercial buildings is wasted, according to the U.S. Environmental Protection Agency. Lighting has a large potential for energy savings for any U.S. building end use, with a significant fraction of that potential coming from lighting controls.
