The 3-Node model requires several other objects to work. You have to specify the height of the supply. I would choose the height eqaul to the average vertical temperature accross all the supply heights (I assume you have 1 height per step of the tribune).

Jean,Thanks for you comment !
I have another question.I said the under-seat air supply system adopted in the auditorium area,and it just need to cool down the temperature near the seat.So is it need to split the zone horizontal? Two zone that near the seat and one zone between them.Zane
There exists a 3-node roomair model that you could consider to use. It's often better than splitting the zone vertically. I would however suggest doing a CFD to help align the inputs of the 3-node model.Mit freundlichen Grü�en- Sent from my iPhone (excuse the brevity)i. A.Jean Maraisb.i.g. bechtoldTel. +49 30 6706662-23Hi, guys. I got a project that need to calculate cooling and heating energy of a gymnasium. And here I have two questions to ask for comment. 1. The form of object is not a typical one. It has inclined curtain wall with some louver on it, and the roof was designed into streamline shape, the height of central section is lower than two side. Is it possible to build the model like object form(by openstudio or designbuilder) or need to simplify? If need to simplify, what kind of method do you think is the best one? 2. The under-seat air supply system adopted in the auditorium area. But as you know, the temperature in large space is different by the height. So, is it need to separate several zone by height and temperature or just one big zone is ok? Looking forward your reply. Thanks very much!!
