Modelling internal doors

asked 3 years ago

Hello, I have a very basic question. When modelling doors between two adjacent rooms (internal door), does the door need to be modelled in the two adjacent surfaces, or in one of the adjacent surfaces is enough?

Thank you.

My opinion: a door between two spaces which have near-identical temperatures need not be modeled at all. Even if the spaces have somewhat different temperatures, the door is probably a small percentage of the wall and affects energy insignificantly. I sometimes ignore even exterior doors when there are few and their U-value is not too different than the adjacent wall. When an exterior door has glazing, however, it gets included in my model.

I take it that in the case one wants to model the door, even though an internal door might have an insignificant contribution, it then needs to be modelled in both surfaces.
