Latest Changes in California Building Energy Standards 2022 : Title 24 2022 Update and its Impact on Single-Family Building Energy Efficiency Standards

Performance Compliance:

New energy design rating (EDR) metrics – EDR1, Title 24 Compliance now require to meet  EDR1, efficiency EDR2, and total EDR2 separately.

Prescriptive Compliance:

  • Space heating equipment must be a heat pump only in certain climate zone.
  • Water heating equipment must be an HPWH meeting certain criteria or a solar water heating system with an electric backup.
  • a gas instantaneous water heater in a certain climate zone is allowed if the space air conditioning unit is a heat pump
  • install an electric water heater with point-of-use distribution is allowed in the new unit under 500 SF
  • a whole-house fan is not required in a new dwelling unit with a conditioned floor area under 500 SF

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.


Choose the Right Energy Compliance Method for Your Building: Title 24 Prescriptive vs. Performance

As California continues to set the bar for energy efficiency, building owners and contractors must comply with the state’s energy code – Title 24. When it comes to energy compliance, there are two main methods to choose from: the prescriptive method and the performance method. In this article, we will explore the differences between the two methods and help you decide which is right for your building project.

Title 24 Calculation Submittal Process: A Guide for Contractors and Building Owners

California’s Title 24 energy code requires all new construction and renovation projects to meet certain energy efficiency standards. To ensure compliance, building owners and contractors must submit a Title 24 report to the building department before construction can begin. In this article, we will guide you through the Title 24 submittal process and help you navigate the building department with ease.

Building Envelope: A Key Element in Title 24 Compliance

In California, building energy efficiency is regulated by Title 24 of the California Code of Regulations. To meet these regulations, it’s crucial to understand the importance of the building envelope. The building envelope, which consists of the walls, roof, and windows, plays a crucial role in determining the energy efficiency of a building. In this article, we will discuss the building envelope and its impact on Title 24 compliance.
