What defines the prerequisite for the water efficiency in the LEED certification process?

The prerequisite for water efficiency in the LEED certification process focuses on the reduction of overall water consumption. This is essential for both environmental sustainability and resource conservation. By aiming to decrease water use, the LEED program promotes practices that help mitigate the depletion of water resources, minimize the impact on water systems, and reduce utility costs for building occupants.

This approach encourages various strategies, including the installation of water-efficient fixtures, optimizing irrigation strategies, and implementing landscaping practices that require less water. By setting a goal for reduced water consumption, LEED aligns with larger initiatives aimed at addressing water scarcity and environmental degradation, thus furthering its commitment to sustainability.

In contrast, other options like the requirement to have only native landscaping or the inclusion of decorative water features do not encompass the broader goal of reducing overall water use. Native landscaping can contribute to water efficiency but is not a definitive prerequisite, and decorative water features typically consume additional water, potentially counteracting water efficiency efforts. Maximal surface water destruction goes against the principles of sustainable design and water management, making it an incompatible choice for a LEED prerequisite.
