Understand the Importance of HERS Rating in California’s Title 24 Energy Code Compliance

As California strives to become a leader in energy efficiency, the state’s energy code – Title 24 – plays a crucial role in reducing energy consumption in buildings. One of the key components of Title 24 is the Home Energy Rating System (HERS) index, which is used to measure a building’s energy efficiency. This blog will discuss the importance of HERS rating in Title 24 compliance and how it benefits builders, homeowners, and the environment.

What is HERS Rating?

HERS rating is a standardized system that uses a numerical score to evaluate a building’s energy efficiency. The lower the score, the more energy-efficient the building is. The rating is determined by evaluating various factors such as insulation, windows, HVAC systems, lighting, and appliances. A HERS rating of 100 represents a standard reference home, while a rating of 0 represents a zero-energy home.
