Which item is not addressed by Title 24 energy standards?

• A. Lighting and related systems energy efficiency.
• B. Daylighting controls and energy efficiency in lighting.
• C. Structural insulation requirements.
• D. Efficiency measures for electrical systems.

Answer: (C)

Title 24 energy standards focus on reducing building energy use through electrical means—primarily lighting efficiency, lighting controls (including daylighting controls), and efficiency measures for electrical systems like motors and transformers. These standards are designed to address how electricity is used in the building and how to cut that usage through efficient lighting and equipment. Structural insulation requirements, which govern how well a building is insulated to reduce heat transfer, are not part of these electrical-energy standards; they fall under the building envelope provisions and other insulation-related codes outside Title 24’s electrical-focused scope. So, while insulation affects overall energy use, the specific insulation requirements are addressed elsewhere, not by Title 24 energy standards.
