<p class="MsoListParagraph"><span style="color:red">The software doesn’t (as far as I know) calculate holes. It will calculate heat transfer through a surface. In terms of boundary – it calculates heat transfer to a space from exterior conditions through an
exterior wall, and from adjacent spaces through interior walls. The absence of a surface (I think) makes that area adiabatic – no heat transfer, mass, or any exchanges. It also means there is no daylight coming into the space from that wall. As far as natural
ventilation goes – I think the way to model that is as an infiltration with a schedule.
