Which of the following is required for a cooling tower and evaporative condenser in the Water Efficiency Prerequisite, Indoor Water Use Reduction?

For the Water Efficiency Prerequisite, Indoor Water Use Reduction, cooling towers and evaporative

condensers must have makeup water meters to measure the amount of water used, conductivity

controllers to optimize water quality and minimize consumption, and overflow alarms to prevent

excess water use.

Reference: The LEED v4 Indoor Water Use Reduction Calculator is a tool that includes assumptions

for baseline water use and helps in documenting water use reduction strategies, which would involve

the use of makeup water meters and conductivity controllers1. Additionally, the LEED v4 reference

guide for water efficiency credits outlines the need for water use reduction and the strategies to

achieve it, which align with the requirements of makeup water meters and conductivity controllers2.
