the baseline automatically follow suit? Or does one have to first construct the baseline case model to determine the self-sized heating capacity to determine if the space is conditioned or semi-heated? It sounds like it would be an iterative process – first
model the space with exterior insulation for a conditioned space then determine the heating capacity. If it shows a semi-heated space, then change the insulation and check again, and so on?</span><o:p></o:p></p>
