LEED Green Associate (LEED GA) — Question 45

Light trespass beyond the project boundary can be prevented by the use of

Answer options

• A. flood light fixtures
• B. up-lighting fixtures
• C. shielded light fixtures
• D. increasing the number of light fixtures

Correct answer: C

Explanation

The correct answer is C, as shielded light fixtures are designed to direct light precisely where it is needed, reducing light trespass. In contrast, flood light fixtures and up-lighting fixtures can cause excessive light spill, and simply increasing the number of fixtures does not address the issue of light trespass.
