If I draw a base model - say a 215mm thick solid brick wall terraced house, and then I want to run a simulation of the building with a hypothetical retrofit of 100mm of external solid wall insulation, will I have to then re-draw the geometry to make the sketchup drawing match?
I say this because the surfaces in OpenStudio are 2D and should represent the external face of the building - not the internal face. This would therefore mean that if I simply changed the construction set to reflect an addition of 100mm of external insulation, OpenStudio would 'think' that this was inside the initial external measurement - essentially modelling moving the brick wall 100mm inwards and putting the insulation where the brick wall used to be.
Am I missing something here, or will I really have to change the geometry for each different external wall insulation thickness that I want to simulate?
Thanks,
Jack
