Is it required to use one of the turbulence models as long as one only cares about general temperature distribution? Let's say I don't care much about eddies development, all I care about is just temperature distribution through the building structure. Is turbulence a key factor?

Just to speed up the process, I would try to simplify my simulation as much as possible, therefore skip turbulence.

Is it an acceptable, common procedure?

Thanks,
