Daylighting sensors adjust artificial lighting based on natural light levels, optimizing energy use in a south-facing office with abundant daylight. This is most efficient per ASHRAE 90.1, reducing electricity costs and glare while maintaining comfort. Roller shades (A) control light but aren’t a lighting system. Automatic timers (B) lack real-time adaptability. Occupancy sensors (D) turn lights off when unoccupied but don’t leverage daylight. For a south-facing suite, daylighting sensors (C) maximize efficiency by balancing natural and artificial light.
Verified Answer from Official Source:C - daylighting sensors
"Daylighting sensors are the most efficient lighting control for spaces with significant natural light, such as south-facing offices, adjusting illumination dynamically." (NCIDQ IDPX Study Guide, Section 2: Building Systems)
Explanation from Official Source:The NCIDQ highlights daylighting sensors as a sustainable solution, aligning with energy codes and enhancing occupant comfort in well-lit spaces.
Objectives:
Integrate efficient lighting systems (IDPX Objective 2.6).
