CLTC participated in the 2019 Title 24, Part 11 CALGreen code-development process to incorporate lower CCT standards for certain outdoor lighting applications. CLTC provided key testimony and support during public meetings in support of this specification. Considerable scientific data currently exists indicating that light at night can be a significant issue in terms of circadian disruption leading to poor health and wellness outcomes.
Light & Health
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.
The Consortium for Energy Efficiency in Non-Residential Buildings (The Consortium), supported by the National Council for Science and Technology and Secretary of Energy in Mexico, is focused on reducing electricity demand in Mexico’s non-residential buildings through collaborative efforts with industry, government and universities. Specifically, the Monterrey Institute of Technology and Higher Education, with assistance from UC Davis, is funded to implement an energy efficiency laboratory featuring lighting and air conditioning technologies for non-residential buildings.
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.
Popular Science—Popular Science highlights health damages of the light we have been using for the past 100 years and new plans of improvement. Professor Michael Siminovitch shares his insights. This article was originally published in the January/February 2016 issue of Popular Science.
CLTC is partnering with Liberty to create a zero net energy community in West Sacramento along the Sacramento River. The Liberty Lighting Guide provides design and technical specifications, application of directives, as well as Title 24 code compliance requirements for residential, outdoor, private community clubhouses, K – 8 schools, private clubhouses, neighborhood commercial spaces, parks, greenbelts, trails, sports, and recreation centers.
