Which strategy is commonly used to reduce outdoor water use in LEED projects?

Utilizing native plants that require less irrigation is a widely adopted strategy in LEED projects to reduce outdoor water use. Native plants are well adapted to the local climate and soil conditions, which means they typically require less water to thrive compared to exotic species that may need more irrigation to survive in a non-native environment. This approach not only conserves water but also supports local biodiversity by providing habitat for native wildlife and helping maintain the ecological balance.

In contrast, planting a variety of exotic species can lead to increased water consumption, as these plants often necessitate additional irrigation to establish and maintain themselves. Minimizing the size of irrigation systems could contribute to water efficiency, but it does not directly address the selection of plants which is crucial for reducing overall water needs. Installing additional water fountains would likely increase water use rather than reduce it, emphasizing the importance of prioritizing plant selection and landscaping practices in sustainable water management strategies.
