Title 24 Residential-New Construction

What is Title 24? Title 24 forms a crucial part of the California Code of Regulations, setting stringent standards for the energy efficiency of new and renovated residential buildings. Its primary goals are to foster environmental health, drive energy savings, and support the reliability of the electricity grid.

Key Residential Requirements of Title 24:

  1. Building Envelope and Insulation:

    • Objective: Minimize energy loss by creating an effective barrier between the interior and exterior.
    • Standards Include:
      • Enhanced wall and attic insulation to reduce heat transfer.
      • High-quality, energy-efficient windows with optimal U-factor and SHGC ratings.
      • Duct systems designed to be sealed effectively, preventing energy leakage.
  2. HVAC System Requirements:

    • Focus: Ensure heating, ventilation, and air conditioning systems are efficient and well-suited to the building’s needs.
    • Criteria:
      • Accurate system sizing for the specific dimensions of the home.
      • High-efficiency ratings for air conditioners (SEER) and heaters (AFUE).
      • Post-installation checks to ensure compliance with performance standards.
  3. Lighting and Appliance Standards:

    • Aim: Reduce energy consumption through advanced lighting and efficient appliances.
    • Regulations:
      • Mandatory use of Energy Star-certified appliances.
      • Installation of advanced lighting controls to decrease unnecessary energy use.

Why Comply with Title 24? Complying with Title 24 is more than a legal requirement; it’s a commitment to energy conservation and a sustainable future. Whether you’re building or renovating a residential property in California, understanding and implementing these standards is key to ensuring energy efficiency and environmental responsibility.

Title 24 Calcs utilizes California Energy Commission-approved software for energy modeling, an essential step in ensuring your building meets energy efficiency standards. This software generates a comprehensive report based on specific inputs, such as building dimensions, construction materials, and HVAC system characteristics. The report’s primary purpose is to determine if your design complies with Title 24 requirements, or if additional measures or HERS (Home Energy Rating System) verifications are needed.

Following the construction phase, a HERS rater conducts a thorough inspection of the completed home to assess its energy efficiency in relation to Title 24 standards. This evaluation results in the creation of a HERS rating, serving as a benchmark to gauge the overall energy performance of your newly constructed property.

To obtain a building permit in California, it’s imperative that your design adheres to Title 24 requirements. The Title 24 report provides detailed insights into the energy efficiency of your design, ensuring it meets these standards.

To initiate the compliance process, ordering the Residential – New Construction Title 24 Energy report is a straightforward procedure. However, certain specific details must be provided, including your building plan with information such as orientation, window and door specifications (including U value and SHGC), insulation materials, and data regarding the water heater and A/C unit.

Title 24 compliance can be achieved through two approaches: the Prescriptive approach and the Performance approach. Each has its pros and cons. The software employed for this report takes into account various factors, including the building’s shape, construction materials, and HVAC system details. By inputting these specifics, the software accurately determines whether your design aligns with the required energy efficiency standards.

In summary, the Residential – New Construction Title 24 Energy report is a crucial component for anyone embarking on a residential construction project in California. It is essential to order this report to ensure your new home complies with energy efficiency standards and fully aligns with Title 24 requirements. Obtaining this report marks the beginning of your residential new construction project’s compliance process.
