Which considerations govern electrical design and lighting in PDD?

• A. Roofing material selection
• B. Landscape lighting only
• C. Power distribution, lighting levels/controls, emergency lighting, electrical code compliance
• D. Acoustic panels

Answer: (C)

Electrical design and lighting in PDD center on how power is distributed, how lighting is provided and controlled, emergency illumination requirements, and compliance with electrical codes. Power distribution plans ensure reliable circuits, panels, feeders, and coordination with other systems for safety and efficiency. Lighting levels and controls address occupant comfort, task performance, daylight integration, and energy use, including calculations for lighting power densities and strategies like sensors and daylight controls. Emergency lighting requirements guarantee safe egress during outages, typically involving battery-backed fixtures and exit signs with proper testing. Electrical code compliance covers wiring methods, grounding, protection, labeling, and the permit/inspection process to ensure safety and legality.

Other options describe aspects that belong to different conversations: roofing material relates to the building envelope, landscape lighting to site-specific lighting outside the building, and acoustic panels to interior acoustics—not the central focus of electrical design and lighting in PDD.
