Final answer:
Irrigation impacts LEED categories such as Water Efficiency, Sustainable Sites, and potentially Energy & Atmosphere by promoting water conservation, minimizing impact on ecosystems, and affecting the building's energy use if irrigation systems require energy.
Step-by-step explanation:
Irrigation can impact various LEED categories, which refer to the impact categories outlined by the Leadership in Energy and Environmental Design (LEED) certification system. These categories are designed to evaluate the environmental performance of a building and its site. When considering irrigation specifically, LEED categories that can be influenced include Water Efficiency, Sustainable Sites, and potentially Energy & Atmosphere.
Under the Water Efficiency category, sustainable irrigation practices can minimize water use, promoting water conservation by using water-efficient landscaping and irrigation equipment. The Sustainable Sites category evaluates the use of the site, including its landscaping and irrigation practices, with a focus on minimizing the impact on ecosystems and water resources. For Energy & Atmosphere, irrigation might indirectly contribute if the irrigation systems require energy to operate, thus affecting the building's overall energy use.
