I am setting up an energy model in HB Energy. The default surfaces’ Boundary Conditions are “Outdoors”, “Adiabatic”, and “Ground”. However, in the EnergyPlus list of boundary conditions there are more options of which the “Zone” seems more realistic for some surfaces in my model. I don’t know really how this option, “Zone”, can affect the heat flow calculations. There is another option, Outside Boundary Condition Object, in BuildingSurface:Detailed of EP (not implemented in HB Energy) that is not required but seems feasible for some surfaces. Since I have used face model to build the rooms in order to have more freedom over the materials in my research, it is very tedious to manually edit all the boundary conditions in the IDF editor. Does anyone have any suggestion?
