Dear All, Is there any way to model exhaust flows from one space to another in eQuest? I know that for modelling exhaust only spaces using a plenum is the best way, but this only assumes that the air in the space is being exhausted to the outside. Please correct me if I am wrong. The specific case we are dealing with is exhausting from storage rooms in the basement into adjacent car parking areas, from where separate exhaust fans supported by jet fans for air movement are exhausting the air. Thank you, Omer Moltay
