Which sustainable construction practice contributes to LEED Water Efficiency credits?
Correct Answer
B) Installing low-flow plumbing fixtures
Installing low-flow plumbing fixtures reduces water consumption and contributes to LEED Water Efficiency credits. The other options contribute to different LEED categories like Materials or Indoor Environmental Quality.
Why This Is the Correct Answer
Installing low-flow plumbing fixtures directly reduces water consumption in buildings, which is the primary goal of LEED Water Efficiency credits. These fixtures include low-flow toilets, faucets, and showerheads that use significantly less water than standard fixtures. The LEED Water Efficiency category specifically measures and rewards strategies that reduce potable water use, and low-flow fixtures are one of the most common and effective methods to achieve these credits. This practice can contribute to prerequisites like Water Use Reduction and credits for Indoor Water Use Reduction.
Why the Other Options Are Wrong
Option A: Using recycled steel reinforcement
Using recycled steel reinforcement contributes to LEED Materials and Resources credits, not Water Efficiency credits. This practice helps with recycled content requirements and diverts waste from landfills.
Option C: Specifying low-VOC paints
Specifying low-VOC paints contributes to LEED Indoor Environmental Quality credits by improving indoor air quality, not Water Efficiency credits. VOCs (Volatile Organic Compounds) affect air quality, not water consumption.
Option D: Implementing construction waste recycling
Implementing construction waste recycling contributes to LEED Materials and Resources credits by diverting construction waste from landfills, not Water Efficiency credits. This practice addresses waste management, not water conservation.
Memory Technique
Think 'FLOW for H2O' - low-FLOW fixtures save water (H2O), making them perfect for Water Efficiency credits. Each LEED category addresses what its name suggests directly.
