For many years, California has been achieving lighting energy efficiency savings through its Appliance Efficiency Regulations (Title 20) and Building Energy Efficiency Standards (Title 24, Part 6). While Title 20 applies at the point of sale and Title 24 applies to new construction and alterations, both work in tandem to support California’s lighting market transformation efforts. This presentation aims to provide clarity for market actors on when each regulation applies and how to comply with both. Using a sample project, we'll provide an overview of California’s lighting regulations with a focus on their purpose, applications, certification processes, correlation, and code change updates. Hands-on demonstrations will give attendees the tools to identify the features a lamp needs to meet one or both regulations, and where those compliant products can be found. This training will facilitate industry access to California’s enormous and evolving lighting market.
