Title 24 refers to a set of building energy efficiency standards in the state of California, United States. These standards are established by the California Energy Commission (CEC) and are part of the California Code of Regulations. Title 24 covers various aspects of building construction and energy usage to promote energy efficiency, reduce greenhouse gas emissions, and support sustainable building practices.

Title 24 consists of different parts, each addressing specific aspects of energy efficiency in buildings:

1. Title 24, Part 6: This part, also known as the Energy Code, focuses on the energy efficiency requirements for residential and non-residential buildings. It includes regulations related to building envelope insulation, lighting systems, HVAC systems, water heating, and other energy-consuming components. The Energy Code sets minimum energy efficiency standards that new buildings and major renovations must meet.

2. Title 24, Part 11: Part 11 of Title 24 focuses on the energy efficiency requirements for appliances and equipment. It includes regulations for various appliances, such as refrigerators, air conditioners, water heaters, lighting fixtures, and others. The standards aim to ensure that appliances and equipment sold or installed in California meet specific energy efficiency criteria.

The Title 24 standards are periodically updated to keep up with advancements in technology and to further enhance energy efficiency goals. The regulations are enforceable by local building departments and compliance is required for new construction, additions, and alterations.

Title 24 plays a significant role in California’s commitment to reducing energy consumption and combating climate change. By implementing energy-efficient practices outlined in these standards, buildings in California can reduce their energy usage, lower utility costs, and contribute to a more sustainable future.
