LEED Green Associate Practice Test

How is daily water use calculated in the WE category?

1. Using historical water usage data

2. By estimating based on building occupancy

3. Using the Energy Policy Act of 1992

4. By averaging seasonal water consumption

The correct answer is: Using the Energy Policy Act of 1992

The correct approach to calculating daily water use in the Water Efficiency (WE) category involves using the guidelines established by the Energy Policy Act of 1992. This act provides a baseline standard for water consumption within buildings, particularly focusing on fixture performance and overall water use reductions. By following these guidelines, projects can assess water use in a standardized way, ensuring consistency and potential compliance with LEED requirements. While historical water usage data, estimates based on building occupancy, and seasonal averages can be part of understanding water use patterns, they do not establish a primary methodology for LEED calculations. The Energy Policy Act offers clear benchmarks that are specifically designed to guide projects in their water efficiency strategies, making it the most relevant choice for accurately calculating daily water use in the context of LEED certification.
