I'm currently dealing with a convention center that has large ballrooms and meeting rooms served by multiple AHUs. Given that it isn't easy to know the exact square footage each AHU serves and that the partitions in the drawings are movable can I consider all the AHUs together to verify the 30% outside airflow increase or do each of the AHUs need to meet the requirement? Thanks

The AHUs have diffusers that are permanent correct? My recommendation is that you draw a border around the diffusers and calculate based on that area. Make sure the full area is covered and there aren't overlaps.
