In daylight optimization, what is the main objective relevant to LEED?

• A. Maximize daylight while controlling glare to improve occupant comfort and energy use
• B. Reduce daylight to minimize cooling loads
• C. Daylight optimization has no LEED relevance
• D. Maximize daylight while ignoring glare

Answer: (D)

Daylight optimization in LEED aims to use as much natural light as possible while keeping visual comfort and energy performance front and center. The goal is to maximize daylight availability to reduce electric lighting use, but this must be balanced with effective glare control and reasonable solar heat gain through thoughtful glazing, shading, and interior design. This balance is what LEED rewards, since simply maximizing daylight without addressing glare would lead to uncomfortable spaces, and reducing daylight to cut cooling would miss the intent of using daylight to save energy.
