If we install subsystem metering for the irrigation systems to comply with WEc1 can we follow the “Non-Metered Irrigation” option at WEc3? This is because historical data are not available since the subsystem metering was installed only prior to commencement of the performance period. However, it seem quite contradictory when selectin the “Non-Metered Irrigation” option which is determined as the case when “Irrigation systems are not metered separately from other water subsystems at the project building and associated grounds”. Has anyone ever experienced this issue before?
