LEED AP Building Design and Construction (BD+C) Practice Exam

What is the required percentage reduction of outdoor water use for achieving the WE Credit?

1. 30%

2. 40%

3. 50%

4. 60%

The correct answer is: 50%

The correct answer is a required percentage reduction of 50% in outdoor water use to achieve the Water Efficiency (WE) Credit in LEED for Building Design and Construction (BD+C). This credit aims to encourage the use of sustainable landscaping practices and efficient irrigation systems, which contribute to lower water consumption. By achieving this reduction, projects not only contribute to resource conservation but also help in minimizing the potential impacts on local water resources. The 50% reduction requirement necessitates strategies such as selecting drought-resistant plants, implementing xeriscaping methods, using efficient irrigation systems, and applying rainwater harvesting. This multifaceted approach ensures that projects can effectively reduce reliance on potable water for landscape needs, promoting a more sustainable environment. The other percentage options represent varying levels of ambitious goals, but only a 50% reduction meets the specific criteria set out for this LEED credit. This structured approach to water efficiency not only supports environmental stewardship but also can lead to long-term cost savings for building owners and occupants, underscoring the importance of effective water management practices in sustainable building design.
