Makeup water meters, conductivity controllers and overflow alarms

According to the Water Efficiency Prerequisite for Indoor Water Use Reduction, cooling towers and evaporative condensers must be equipped with makeup water meters, conductivity controllers and overflow alarms to reduce water consumption and prevent water waste. These devices help monitor and control the water quality, flow rate and level of the cooling system, and alert the operators of any malfunctions or leaks.

References: As per the LEED AP Building Design + Construction (LEED AP BD+C) V4 resources, the installation of makeup water meters, conductivity controllers and overflow alarms is a requirement for cooling towers and evaporative condensers under the Water Efficiency Prerequisite for Indoor Water Use Reduction. This prerequisite aims to reduce indoor water consumption by setting baseline and efficiency standards for fixtures, fittings, appliances, equipment and processes. For cooling towers and evaporative condensers, the prerequisite also requires efficient drift eliminators that reduce drift to a maximum of 0.002% of recirculated water volume for counterflow towers and 0.005% of recirculated water flow for cross-flow towers. For more detailed information, you can refer to the web-based reference guide in the credit library at USGBC’s official website.

The WaterSense label or local equivalent requirement in Water Efficiency Prerequisite, Indoor Water Use Reduction ensures that eligible newly installed plumbing fixtures will be both water efficient and high performing. The WaterSense label is a voluntary program by the U.S. Environmental Protection Agency (EPA) that identifies and promotes water-efficient products that meet EPA’s specifications for water efficiency and performance. The label applies to tank-type toilets, water-using urinals, private lavatory faucets, and showerheads. For projects outside the U.S., local equivalents may be used if they meet the same criteria as WaterSense or are listed on the USGBC website. The label does not imply that the fixtures are LEED compliant, comply with mandatory federal government regulations, or comply with all international plumbing system requirements. References:

remediate sites already in decline

When a project team sustainably develops a project site, the design should aim to remediate sites already in decline, such as brownfields, degraded lands, or abandoned properties. By doing so, the project can restore the environmental quality, ecological functions, and social value of the site, as well as reduce the pressure on undeveloped lands and natural habitats. LEED offers credits for projects that choose to locate on and remediate sites already in decline, such as the Sustainable Sites Credit, Site Assessment and the Sustainable Sites Credit, Brownfields Remediation1.
