Marco,
  My understanding of combined air flow / thermal models is that there are basically two bulk air flow modeling tools available: COMIS and CONTAM. The link between EnergyPlus and COMIS is built in to EnergyPlus whereas there are three options when it comes to the link between TRNSYS and bulk air flow modeling tools. There is a version of the TRNSYS building model (Type56) that has COMIS built into it; that version of Type56 is called TRNFlow. The second option is that the interface for TRNSYS (the Simulation Studio) can also be used as the interface for COMIS. In this mode, you develop a COMIS model and a TRNSYS model, then link them together. The third TRNSYS option is that the bulk air flow modeling tool called CONTAM is implemented as a standard TRNSYS Type. You are able to download CONTAM, develop your air flow model, export it for use in TRNSYS and then treat it as another Type in your simulation.
Kind regards,
 David

Dear all,
 
I have being using COMIS in 2004,
and now I think I'm going to use EnergyPlus in a few months;
as a doctorate student en LaSalle-URL university in Barcelona.
they told my thet EP includes a multizone air-flow model;
I don't know if is it corect and y like to know, if it has hte same posibilitys and aplications of COMIS;
which is the difference between Comis+Transys
and EP.
 
Thank you for your sugestions!
best regards,
marco
