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?

Yes, this actually isn't all that uncommon a problem as many teams will install irrigation sub-metering systems toward their EBOM certification efforts, but historical separately metered data does not exist to define the baseline. In this case, just provide a narrative under 'Special Circumstances' explaining that while an irrigation sub-meter has been recently installed, there is no historical sub-metered data to define a base case from, and you are therefore approaching the credit using the non-metered compliance path.

I have a question about a variation of this question. My client has had irrigation sub metered for many years. We want to pursue this credit and know that we need to replace most of the landscaping. We are in the performance period now and the landscaping is not yet installed. Their landscape architect told them that they can pursue the credit using Option 2 as long as there's a signed contract to begin the installation of the landscaping by the end of the performance period. Has anyone else found this to be a plausible way of meeting the credit? Thank you.
