[EnergyPlus_Support] Re: Infrared Transparent Materials
Hello
I am new in modelling and I am about to model an Atrium. I wanted to ask it I use the Infrared Transparent surface, do I have to model for example for a 3-leves Atrium 3 Zones and set as Infrared Transparent surfaces their adjacent surfaces, or do I have to create only one Zone and divide it in a way?
If I model it this way, by opening a window at the lower level, will the air move till the Zone at the upper level or will it be "trapped" at the lower level?
Thank you alot for your help

Open plan spaces are one application; another is stacking zones within a space in the vertical direction. They do not transmit daylight. I don't believe they are intended for surfaces exposed to the outdoors.

It is not difficult to have one of this type of surfaces if you deal with buildings with atrium or courtyards. As you cannot have one zone inside another you have to break open plan configurations somehow and that is when a 'void' surface would be needed.
