Exterior lighting generally operates from early evening through early morning, a period of little to no renewable energy generation, which means this lighting is primarily powered by carbon-dense fossil fuels. Fossil fuel use is a significant contributor to greenhouse gas emissions (GHG), poor air quality, water pollution and land degradation. In addition, low-quality exterior lighting characterized by poor color, inappropriate light distribution, and inadequate light levels has also been linked to increased crime rates and reduced physical activity within the surrounding community.
CLTC is excited to announce an update to the Daylight Harvesting for Commercial Buildings Guide! This publication provides guidance towards meeting and exceeding California's 2019 Energy Code for daylight harvesting.
Daylight design guidelines and associated Energy Code are provided in an easy to read, side-by-side layout, organized into sections for each building-related discipline that impacts daylight performance from building siting, through architectural and interior design, to construction, commissioning and operation.
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.
CLTC, in partnership with the Center for Sustainable Energy (CSE) and the California IBEW-NECA Labor Management Cooperation Committee (CA LMCC) is working to expand career pathways in the electrical industry. With new funding from the California Energy Commission, CLTC will develop training resources to increase workforce development opportunities in disadvantaged communities.
On July 29 CLTC Director Michael Siminovitch delivered the keynote address at the 2014 DesignLights Consortium Stakeholder Meeting. Professor Siminovitch's presentation included case study results and information on the emerging lighting and control technologies deployed for UC Davis's Smart Lighting Initiative.
2014 DesignLights Consortium Stakeholder Meeting, San Diego
Presented by Michael Siminovitch
On July 29, 2014, CLTC Director Michael Siminovitch gave a keynote address to those gathered for the annual DesignLights Consortium Stakeholder Meeting. The attached presentation begins with examples of wasteful lighting practices then explores control strategies and emerging technologies that have demonstrated deep energy savings. Case study results and information on UC Davis's Smart Lighting Initiative are included.
These presentation slides cover best practices for residential lighting design. The material is designed to help builders meet, or exceed, California's 2008 Title 24 Building Energy Efficiency Standards. It includes background and policy, common lighting terms and technology updates, guidance in residential lighting design, a step-by-step overview of the Title 24 compliance process, and additional resources.
CLTC communicates and collaborates with the Energy Division of the California Public Utilities Commission (CPUC) to provide objective information and expert analysis that may inform the Commission’s lighting-related energy policies, programs and mandates. CLTC supports the CPUC’s Energy Division in its lighting-related goals, initiatives and activities, including the Lighting Action Plan, a near-term implementation guide for achieving the goals stated in the Lighting Chapter of California’s Long-Term Energy Efficiency Strategic Plan.
