What is the requirement to achieve the credit in SS Light Pollution?

To achieve the credit in the Sustainable Sites (SS) category for Light Pollution, the primary requirement is focused on limiting light pollution to minimize the impact on the surrounding environment, particularly for nearby habitats and urban areas. The option stating that "1 credit available for all projects" accurately reflects that all projects pursuing LEED certification can earn one credit for meeting the criteria associated with light pollution.

This credit encourages strategies such as the use of downlighting, appropriate fixture shielding, and limiting the amount of light spill beyond the property lines to reduce the effects of artificial lighting on ecosystems and human health. The emphasis is on the implementation of effective lighting design rather than specific requirements such as energy efficiency for all lighting fixtures, complete prohibition of exterior lighting, or the requirement for motion sensors. Each of those aspects may contribute to reducing light pollution but are not the fundamental requirement for earning the credit directly. Thus, the correct answer points to the availability of the credit itself as applicable to all projects, reinforcing the intent of promoting responsible outdoor lighting practices across the board.
