How to model rooms combined as a single zone? Should they have partition wall between them or not? Obviously this will only apply to the rooms which are adjacent to each other not the one which are apart but considered as same zone. If adjacent rooms are kept at same conditions then those partition walls will act like adiabatic walls (no heat transfer). How you guys model this situation?
What if the rooms (considered as one zone) has slightly different number of occupants? Another concern could be that modelling partition walls will also increase simulation time for a larger building.
Also, do you guys model doors? Does modelling them has large impact on energy consumption? I am just trying to save some computational time and was thinking of different options. Any ideas to reduce computational time will be appreciated as well. :)
