LEED Green Associate (LEED GA) — Question 98

Which of the following is a strategy for preventing light pollution?

Answer options

• A. Install up-lighting
• B. Install shielded fixtures
• C. Install high performance windows
• D. Use dark paving materials to diminish light distribution

Correct answer: B

Explanation

The correct answer is B, as shielded fixtures are designed to direct light downwards, minimizing light spill into the night sky. In contrast, option A, up-lighting, contributes to light pollution by casting light upward, while option C, high performance windows, does not address outdoor light pollution. Option D, while potentially useful for controlling light distribution, does not specifically target the prevention of light pollution.
