boundary’s landscaped area. Projects can also prorate irrigation data for the project boundary from the campus meter.
Additional considerations Projects that pursue WEc1: Water Metering and Leak Detection, Option 1 Submeters should consider strategies that meet both the prerequisite and credit. For example, using a single utility-owned meter for the project’s total potable water use meets the prerequisite; however, it does not comply with the credit requirements. For WEc1: Water Metering and Leak Detection, Option 1 Submeters, teams must install additional meters to capture each potable water end-use, as outlined in the credit.
Commitment to Sharing Data with USGBC
USGBC aims to collect data on water usage from all LEED buildings. Having this data allows USGBC to identify similarities between high-performing projects and recommend solutions with proven results.
Projects must commit to sharing whole-project water usage data with USGBC annually for at least five years, or until the building changes ownership or lessee. Share data using a USGBCapproved data template or an approved third-party data source, such as ENERGY STAR® Portfolio Manager.
