Title 24 alterations are changes to a building or structure. These changes must follow the rules in Title 24 of the California Code of Regulations. Title 24 is the California Building Standards Code. It sets energy efficiency standards for new construction and changes in California.

When you change a building, you need to make sure the changes follow the energy efficiency rules in Title 24. This involves improving different parts of buildings, like lights, heating and cooling systems, insulation, windows, and appliances. When altering a home in California, here are some key areas of focus:

Building Envelope: The building envelope includes the walls, roof, windows, and doors. Title 24 establishes regulations for the thermal performance of these components. These regulations include requirements for insulation levels and limitations on solar heat gain.

When replacing windows for a Title 24 project, it’s important to make sure the new windows meet energy efficiency standards.

The new windows must have certain features to meet Title 24. These features include low U-factor and Solar Heat Gain Coefficient (SHGC) values. The U-factor measures insulation, while the SHGC values measure heat blocking ability.

Working with our experienced team, we can guide you through the window replacement process for your Title 24 alteration project. Our professionals can assess your specific needs, recommend suitable windows, and ensure their proper installation to ensure compliance with the regulations.

Lighting: Title 24 requires that residential lighting systems meet certain efficiency and control requirements. This includes the use of high-efficacy lamps and the installation of automatic lighting controls such as occupancy sensors and dimmers.

HVAC Systems: Title 24 sets requirements for the efficiency of HVAC (heating, ventilation, and air conditioning) systems. There are rules for making furnaces, air conditioners, and heat pumps work efficiently. These rules also include requirements for duct insulation. Additionally, there are limits on duct leakage.

In addition, the CEC requires residential alterations to have proper insulation to reduce heat transfer and maintain a comfortable indoor temperature. Adding insulation to walls, roofs, and floors helps reduce heat loss or gain. Using energy-efficient windows and doors also helps in reducing heat loss or gain.

To follow Title 24, you need experts who know the rules and can help with the design and construction. This may involve consulting with Title 24 Consultants, architects, engineers, and contractors who have experience in meeting California energy code requirements.
