What is Title 24 California?

California Title 24 Standards
Title 24 California is the 24th part of the California Code of Regulations (CCR), that were passed by the California Legislature in 1978.

Since 1978, all new homes, additions and alterations to existing homes, and most commercial buildings within California are required to meet the minimum energy efficiency standards [ Title 24 Compliance Report ] contained in Title 24, Part 6 of the California Code of Regulations (Building Energy Efficiency Standards).

Energy efficiency reduces energy costs, increases reliability and availability of electricity, improves building occupant comfort, and reduces impacts to the environment making standards important and necessary for California's energy future.

Why California needs Title 24 Energy Efficiency Standards

Energy Savings
Reducing energy use is a benefit to all. Homeowners save money, Californians have a more secure and healthy economy, the environment is less negatively impacted, and our electrical system can operate in a more stable manner.

Electricity Reliability and Demand
Buildings are one of the major contributors to electricity demand. We learned during the 2000/2001 California electricity crisis and the east coast blackout in the summer 2003 that our electric distribution network is fragile and system overloads caused by excessive demand from buildings can create unstable conditions. Furthermore, resulting blackouts can seriously disrupt business and cost the economy billions of dollars. Since the California electricity crisis, the Energy Commission has placed more and more emphasis on demand reductions.

Comfort is an important benefit of energy efficient homes. Energy efficient houses are well insulated, less drafty, and use high performance windows and/or shading to reduce solar gains and heat loss. Poorly designed building envelopes result in houses that are less comfortable. Even with oversized heating and cooling systems, comfort cannot be achieved in older, poorly insulated and leaky homes.
