In California, Title 24 refers to the California Building Standards Code, specifically focusing on energy efficiency in buildings. It encompasses a wide range of regulations aimed at reducing energy consumption, promoting sustainability, and ensuring a comfortable environment in both residential and non-residential structures. 

What it covers:

Title 24 includes various parts, with Part 6, the California Energy Code, specifically addressing energy efficiency standards. These standards cover aspects like lighting, HVAC systems, building insulation, and control systems. 

Purpose:

The primary goal is to minimize energy waste, conserve resources (like natural gas), and extend the use of renewable energy sources. 

Impact:

Title 24 impacts new construction, additions, and renovations of buildings, ensuring they meet specific energy efficiency requirements. 

Key Areas:

Lighting: Requires high-efficiency fixtures and controls. 

HVAC: Sets standards for energy-efficient heating and cooling systems. 

Building Envelope: Addresses insulation, windows, and doors to minimize heat transfer. 

Controls: Emphasizes automated systems for optimizing energy use based on occupancy and time.
