Important Considerations for Minimizing Potable Water Usage in Irrigation for LEED Green Associate Certification
In the pursuit of sustainable and water-efficient landscaping, a crucial factor to consider is the use of native plant species. This strategy, highly recommended for those aiming to pass the USGBC LEED Green Associate exam and earn USGBC LEED Green Associate certification, is one of the most effective ways to reduce potable water consumption for irrigation in LEED projects.
Native plants, well-adapted to the local climate, soil, and rainfall patterns, require less supplemental irrigation compared to non-native species. By maximizing the use of native plants in landscaping, a project can significantly decrease its reliance on potable water for irrigation. This strategy effectively lessens the potable water demand for irrigation in landscaped areas, fulfilling LEED water efficiency credits.
However, it's important to note that while maximizing the use of pervious pavement can help with stormwater management, it does not directly impact the need for irrigation in landscaped areas. On the other hand, minimizing pervious areas would increase runoff and reduce natural groundwater recharge, potentially increasing the need for irrigation.
Conversely, minimizing green roof area would reduce the benefits of green roofs, such as stormwater retention and reduced urban heat island effect, which can help decrease irrigation requirements. Therefore, while it may seem counterintuitive, minimizing green roof area could indirectly lead to an increased need for irrigation.
In LEED projects, using native plant species is not only beneficial for water efficiency but also contributes to the Outdoor Water Use Reduction credit under the LEED v4 Water Efficiency category. By employing this strategy, projects can not only reduce their water footprint but also contribute to a more sustainable and eco-friendly urban environment.
