2019 Title 24, Part 6 Lighting Education Videos

CLTC is excited to release its updated, introductory videos focused on 2019 Title 24, Part 6 lighting requirements!  The videos are designed to increase knowledge and implementation of code-compliant lighting in California’s nonresidential and residential buildings.

DC Lighting Systems Evaluation

The majority of building power distribution systems use alternating current (AC) sourced from a power grid. This significantly influences the design of direct current (DC) appliances including LED light sources and digital controls. 

Long-term Performance Evaluation of LED Lighting Products

CLTC recently completed a four-year EPIC-sponsored research program that included a long-term performance evaluation of commercially available LED light sources.  The study aimed to determine if today’s existing products meet their stated performance when installed in worst-case thermal conditions typical of applications designed to comply with California’s Title 24 requirements.

Evaluation results showed that the tested LED replacement lamps met most of the performance criteria claimed by their manufacturers.  However, 36% of the tested lamps failed prematurely.

IES LD+A Research Matters: Optimizing Building Design and Operations

Designers, owners and operators are all faced with a myriad of decisions on how best to achieve their building design and operational goals. Complex and often conflicting objectives can make even the simplest decisions appear challenging. Take, for example, thermal comfort. According to the Department of Energy, adjusting temperature set points by just one degree for an eight-hour workday can save commercial building owners 3% in energy costs. This equates to thousands of dollars in savings each year.
