Residential Alteration

When making alterations to a residential building in California, it is important to consider Title 24 compliance. Here are some key areas of focus:

Building Envelope: The building envelope includes the walls, roof, windows, and doors. Title 24 sets requirements for the thermal performance of these components, including minimum insulation levels and maximum allowable U-factors and solar heat gain coefficients for windows and doors.

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. This includes minimum efficiency levels for furnaces, air conditioners, and heat pumps, as well as duct insulation requirements and duct leakage limits.
