Title 24 requirements for residential new construction include:
Building envelope: Title 24 sets standards for the building envelope, which includes the walls, roof, windows, and doors of the home. These standards require that the building envelope be properly insulated and sealed to prevent air leaks and heat transfer. Title 24 also sets standards for the energy efficiency of windows and doors, which must meet specific U-factor and Solar Heat Gain Coefficient (SHGC) ratings.
Heating, ventilation, and air conditioning (HVAC) systems: Title 24 requires that HVAC systems meet specific energy efficiency standards, including a minimum Seasonal Energy Efficiency Ratio (SEER) rating for air conditioners and a minimum Annual Fuel Utilization Efficiency (AFUE) rating for furnaces. Title 24 also requires that HVAC systems be properly sized and installed to ensure optimal performance.
Lighting and appliances: Title 24 sets energy efficiency standards for lighting and appliances, including refrigerators, dishwashers, and washing machines. These standards require that appliances meet specific Energy Star ratings, which are designed to reduce energy consumption and greenhouse gas emissions.
To comply with these requirements
Title 24 Calcs can use Title 24 compliance software to perform energy modeling. The compliance software uses inputs such as building geometry, construction materials, and HVAC system characteristics to generate a compliance report that shows whether the proposed design meets Title 24 requirements.
At the end of the construction process, a HERS rater will conduct a field inspection to verify that the home meets the energy efficiency requirements of Title 24. The HERS rater will also generate a HERS rating, which is a measure of the home’s energy efficiency compared to a reference home.
If you are planning to build a new home in California, it is important to ensure that your design meets Title 24 requirements.
