Hi, I am about to start to model a Building which includes a Ventilated Facade. But I don't have any idea how to represent it on the simulation program. The program I know is Design Builder (energy +), but I don't have any idea how to represent it. And the othe question is if I hafe to model the complete concrete and iron structure, or just the spaces. We are trying to achieve an LEED CS 2.0 certification. We have an Commercial area and General Office. Do we have to model tenant spaces? Assuming what they could have, am I right? I'm new in this and I would like to have a little help on this, please! Because I have to do the hole Simulation by myself! Thanks

Interestingly enough we just finished an Energy Plus model with a double facade. This is a bit too involved to explain in a LEED forum. I'd suggest checking in with the Design Builder folks or the Energy Plus help desk on how to do the modeling. Typically you build spaces in a model and them assign characteristics, including mass, to the elements of those spaces. As far as a CS project is concerned - yes you will need to model all the energy use associated with the whole building including the tenant spaces.

Energy Plus has the ability to model ventilated facades. But you must know the software very well. It is an object called: Exterior Natural Vented Cavity, and cannot be modeled in Design Builder, you must do it directly in E+.
