California Title 24

12/17/17

“What is the official building energy efficiency standard for California?”

In the U.S, most building efficiency standards are regulated by ASHRAE 90. However, some states go a little bit further with their regulations. In California, a series of codes known as Title 24 is the law of the land. Title 24 contains all of the specifications that a construction firm must consider before going through with a project. These include a requirement for LED lights, motion sensors for buildings, a specified minimum reflectivity for roofs,  electrical service panels for disaggregated measurement, and many other variables. California Title 24 is updated every 3 years such that the next set of rules saves more energy than the last.
