Water Metering Leed

Powerwise can provide the flow meters as well as the software solution to remotely monitor and report on water use.

Water metering leed. Building level water metering and water metering. Prerequisite building level water metering. There are also two new prerequisites in leed v4 regarding water usage. There are 2 direct prerequisites and 2 8 credits for leed v4 bd c and operations maintenance that require qmc metering systems.

You can t control what you don t measure so this requirement gives owners the tools to recognize when there might be operational problems. Flow meters can measure the overall water use for a building or the building subsystems such as irrigation fixtures domestic hot water boilers and reclaimed water. Electrical or mechanical engineers and energy consultants play a critical role in designing and implementing advanced submetering systems that meet properties and stakeholders evolving needs. Meter water use of at least 80 of the installed domestic hot water heating capacity including both tanks and on demand heaters.

Building level water metering and advanced water metering follow the same logic described above. If a project is pursuing leed certification a building level water metering must be implemented regardless of the utility arrangement. Building owners and operators must now monitor total water use and provide that data to the usgbc. Building level water metering this is a required measure.

As a prerequisite for certification leed requires building level energy metering. Data must be recorded at least weekly. New to leed v4 is this prerequisite requiring the installation of whole building water meters. There are up to two points for metering water end uses like irrigation domestic hot water and cooling towers.

Outdoor water use reduction prerequisite. Leed metering made simple and intelligent september 29 2015. Leed requirements for sub metering sub meteringis a critical component of leed certified buildings. Submetering is a key component of leed certified buildings and the value to property owners and developers is reflected in the credits available from metering in each of the leed rating systems.

On the energy side there are two credits for measuring major end uses that contribute 20 or more of the total annual consumption of the building excluding plug loads. Developers property managers and consultants want a cost effective end to end solution for achieving leed credits. Boiler with aggregate projected annual water use of 100 000 gallons 378 500 liters or more or boiler of more than 500 000 btuh 150 kw. It also requires sharing a building s water usage data with usgbc for five years following certification.
