Hello, I have a system in a hotel that has a constant air volume system of crca 550 l/s and I am not sure how to correspond to the requierement of LEED: 

  • "For constant-volume systems, balance outdoor airflow to the design minimum outdoor airflow rate defined by ASHRAE Standard 62.1–2010 (with errata), or higher. Install a current transducer on the supply fan, an airflow switch, or similar monitoring device."

Would hey-card control and CO2 sensor comply with this requierement? Or what kind of monitoring is expected of me in such cases. The project is Located in Europe, and all the products and design is compliant with local regulation.
