Greetings, I'm new to Comsol, and I'm trying to model a simple shoe-box model for a building, and I'm using a non-isothermal multi-physics model to study building thermal behavior in an urban environment with wind flowing around it, also I will be using a flow coupling multi-physics to model humidity of the wind using Transport of Diluted Species.

What I want to do here exactly is to calculate the cooling load of the building by quantifying the heat flux going inside, through the building walls, while fixing the temperature inside the building to a reference value (24 degrees). I'm planning to calculate the cooling load as a function, but I will be needing different variables; namely; the temperature of the inner and outer walls of the building, the temperature and humidity (moisture concentration) just outside the building walls (for the calculation of infiltration), what would be the way to get these values? I know that for the temperature of the walls I need to define an integration operator on the building wall boundary, but I'm not sure how to do it just outside those boundaries.
