I am working on the IEQp1 LEED form and ran into a couple problems when filling out the information. The building I am working on is 12 stories high and has 3 AHUs (in the penthouse) that supply the entire building. I am trying to fill out the IEQp1 PDF but dont know what to put in for the total occupants. Would I put in the total number of occupants for the whole building, total number of occupants supplied by just one AHU or total number of occupants in the critical zone? Also, is the Az the area of the whole building, area of the building that one AHU supplies or the area of the critical zone? I would appreciate any assistance.
