Before performing indoor water use reduction calculations with metering faucets, what must the project team do regarding flow rates?

  1. Measure water pressure

  2. Convert flow rate to gallons per minute

  3. Install additional fixtures

  4. Determine the total number of cycles

The correct answer is: Convert flow rate to gallons per minute

The correct answer involves converting flow rates to gallons per minute because this standard unit of measurement is crucial for understanding and comparing the performance of metering faucets in water consumption calculations. By converting the flow rate to gallons per minute, the project team can more easily evaluate the potential savings from different fixtures and ensure that the calculations align with the criteria set forth by LEED for indoor water use reduction. This conversion is essential for establishing a baseline and determining whether the flow rates meet certain thresholds for efficient water use. It allows for effective communication of water usage data and supports further analysis for compliance with LEED certification requirements. Properly converting flow rates enables the team to assess overall performance and identify actionable opportunities to reduce water usage effectively. The other options, while they may be perceived as relevant, do not directly address the fundamental requirement of having a clear and standardized measurement of water flow, which is essential for the calculations needed in water use reduction assessments.
