California IDEX Practice Exam

Which requirement is NOT necessary to comply with Title 24 for bedroom lighting design?

1. Dimmers installation

2. Use of non-low efficacy lights

3. Vacancy sensor connection

4. Limiting high-efficacy luminaires to half the total wattage

The correct answer is: Limiting high-efficacy luminaires to half the total wattage

The requirement regarding limiting high-efficacy luminaires to half the total wattage does not align with Title 24’s specific provisions for bedroom lighting design. Instead, Title 24 encourages the use of high-efficacy lighting solutions to improve energy efficiency in residential settings. The implementation of dimmers, the use of non-low efficacy lights, and connections to vacancy sensors are all essential components of the lighting design intended to reduce overall energy consumption and ensure user control over lighting levels. These aspects collectively contribute to compliance with California’s energy efficiency standards, while the limitation on high-efficacy luminaire wattage does not have the same requirement under Title 24, making it unnecessary to fulfill in this context.
