Which statement best describes daylight optimization's impact on energy use and comfort?

• A. It has no relation to energy use
• B. It primarily affects structural materials
• C. It supports energy efficiency and occupant comfort through daylight use and glare control
• D. It only affects aesthetics of lighting

Answer: (D)

Daylight optimization aims to use natural daylight as a primary lighting source to cut electric lighting energy while keeping the space comfortable. When daylight is properly integrated, lighting loads can be reduced through shading strategies, daylight-responsive controls, and smart siting of windows, so occupants still see well-lit tasks without waking up glare or excessive heat. Controlling glare and ensuring even daylight distribution are key to comfort, since uncomfortable glare or uneven lighting can offset any energy savings and reduce occupant satisfaction. Access to daylight and views also enhances well-being and productivity, reinforcing why this approach supports both energy efficiency and comfort. It’s not about aesthetics alone, and it certainly isn’t unrelated to energy use or focused only on structural materials.
