LD+A Research Matters: Performance Evaluation of a Solar Tracking Lighting System

06/07/2022
CLTC recently partnered with the California Energy Commission, Sonoma Clean Power Authority, and Frontier Energy Inc. to evaluate opportunities in emerging daylighting technologies. One such technology is a solar-tracking lighting system, which delivers daylight via optical fibers to core building areas that otherwise do not have access to daylight.

Energy Code Lighting Language Cleanup Initiative

The California Lighting Technology Center, in collaboration with Southern California Edison, RMS Energy Consulting LLC, and the California Energy Alliance, are establishing a working group of industry stakeholders to help develop recommendations that will simplify and clarify the nonresidential lighting and lighting controls language contained in the 2022 Title 24, Part 6 Building Energy Efficiency Standards.

CLTC Publishes Study on Adaptive Lighting in Outdoor Security Applications

Published: Wed, 11/17/2021

Today, adaptive lighting is considered best practice for numerous outdoor applications and has been incorporated into many current energy standards. However, outdoor areas with heightened security requirements are often excluded from adaptive lighting control requirements and these areas remain lit with high, uniform levels of static illumination.

To address this gap, CLTC partnered with the Office of Naval Research to evaluate the energy-savings potential and end-user acceptance of adaptive lighting for outdoor security applications.

Adaptive Lighting in Outdoor Security Applications

11/16/2021
Today, adaptive lighting, which is lighting controlled by occupancy sensors or schedules that adjust light levels based on actual site conditions, is considered best practice for numerous outdoor applications. Adaptive lighting has been adopted as part of some commercial energy standards and the strategy is now included in many outdoor lighting specifications and design guides. Outdoor areas with heightened security requirements, however, are often excluded from adaptive lighting control requirements and these areas remain lit with high, uniform levels of static illumination.

Renewable Energy & Advanced Lighting Systems for Grid-Connected Exterior Applications

CLTC Studies Renewable Energy & Advanced Lighting Systems for Exterior Applications

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.

Daylight Harvesting for Commercial Buildings

Daylight Harvesting for Commercial Buildings for 2019 Building Energy Efficiency Standards
04/13/2021

CLTC is excited to announce an update to the Daylight Harvesting for Commercial Buildings publication!  This in-depth tool provides guidance towards meeting and exceeding California's 2019 Energy Code for daylight harvesting.

Daylight design guidance 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.
