All the in-depth discussion on modeling an Atrium in Openstuido and/or Energy plus on Unmet Hours (such as this one and this one) seem old enough to possibly be out of date.
my understanding is that the proper approach depends on the what sort of design measures/impacts are being investigated. If an accurate prediction of savings from daylighting is desired, then model atrium as a single space allowing for both beam and diffuse penetration. On the other hand, if system loads and energy use predictions are desired then divide atrium and connect the spaces with airflow network objects.
My specific questions are:
1) In general, have any capabilities been added to OpenStudio in the last year or so that would change the response to the threads linked above?
2) More specifically, does OpenStudio provide a way to build the necessary airflow networks to "properly" model large open spaces than have been subdivided by airwalls/interior windows?
3) Are there any other good, up-to-date resources for atrium modeling best practices?
