LEED AP Building Design and Construction (BD+C) Practice Exam

What percentage of building occupants must have individual controls for interior lighting?

1. 75%

2. 90%

3. 100%

4. 50%

The correct answer is: 90%

The requirement for providing individual controls for interior lighting to enhance occupant comfort and satisfaction is outlined in the LEED Rating System. Specifically, the standard stipulates that at least 90% of building occupants should have individual control over their interior lighting. This guideline promotes the design of spaces that empower users to adjust lighting according to their personal preferences, which can lead to increased productivity and well-being. The approach of aiming for 90% also acknowledges that while full individual control may not be feasible or necessary for every space or occupant, a significant majority should still have the ability to tailor their immediate environment. This concept is rooted in human-centric design principles, emphasizing the importance of accommodating the diverse preferences and needs of building users. In essence, achieving this level of control is critical for creating healthier and more adaptable living and working environments, aligning with the overall goals of sustainability and occupant-focused design advocated by LEED standards.
