For a LEED project, which of the following strategies would contribute to earning points in the Water Efficiency category?

Correct Answer

B) Using low-flow plumbing fixtures and native landscaping

Water Efficiency points in LEED are earned through strategies that reduce water consumption, such as low-flow plumbing fixtures and native landscaping that requires minimal irrigation.

Answer Options
A
Installing high-efficiency lighting systems
B
Using low-flow plumbing fixtures and native landscaping
C
Purchasing materials from local suppliers
D
Improving indoor air quality with low-VOC materials

Why This Is the Correct Answer

Option B is correct because the LEED Water Efficiency category specifically focuses on reducing water consumption and managing water resources effectively. Low-flow plumbing fixtures directly reduce indoor water usage, while native landscaping reduces or eliminates the need for irrigation since these plants are adapted to local climate conditions. Both strategies directly contribute to water conservation goals and can earn points in the Water Efficiency category.

Why the Other Options Are Wrong

Option A: Installing high-efficiency lighting systems

High-efficiency lighting systems contribute to the Energy and Atmosphere category, not Water Efficiency, as they focus on reducing electrical energy consumption rather than water usage.

Option C: Purchasing materials from local suppliers

Purchasing materials from local suppliers contributes to the Materials and Resources category by reducing transportation impacts and supporting the local economy, not water efficiency.

Option D: Improving indoor air quality with low-VOC materials

Low-VOC materials improve Indoor Environmental Quality by reducing harmful emissions, not water efficiency or water conservation.

Memory Technique

Use the acronym 'WEIM-ST' for LEED categories: Water, Energy, Indoor, Materials, Sites, Transportation. Match water-saving strategies only to the Water category.
