Overview

A wall can be divided into two different functional categories at the same time.

Method

If you have a wall sharing a portion as a partition with another wall and another portion exposed as an external wall, you can model it in OpenBuildings Energy Simulator.

In the image below, you could see a wall behaving differently in two different sections: 

OpenBuildings Energy Simulator assesses the adjacency and exposure condition of a building element, especially walls, and assigns the functionality of the same. In the image above, you can see the wall having two different conditions; a portion is adjacent to the room beside it and the other is exposed. 

To make the adjacent portion function as a partition wall, you would have to set the adjacency to a range so the software recognizes as a nearby element and sets the workflow accordingly. The rest of the wall, as not having any wall section nearby, will function as an external wall as usual.
