Airflow metering

Hi Tapio This is a funny credit, where it requires you to measure systems and / or end-uses, which is a little confusing. First off, you definitely don't need to install metering at the tenant-level, as this is not the intent of the credit. Additionally, the credit does not necessarily require teams to measure all energy uses downstream of an associated system / end-use level, but rather typically requires the main upstream system / end-use to be measured - in this case, the central AHUs. That said, I'd wait to install metering until you've performed the energy breakdown that is associated with EA Prerequisite 1. If you find that the AHUs are one of the top users, then installing meters at the central air-handlers would help to earn this credit. But make sure to cross check the other credit criteria and metering requirements prior to submitting. Let me know if you have any other questions, Hannah
