Your text slightly disagrees with the title question, so I’ll try to answer both. Reagarding accounting for wind on external surfaces (via convective heat transfer) is taken into account by all major energy modeling software, such as EnergyPlus and IESVE, though there are different options I each to change the calculation methods used to do this. None of which are CFD because the assumption is that the wind matches the weather file and is uneffected by the surroundings. Of course this is an assumption but is often acceptable. Since you asked specifically about CFD integration - I’m it aware of any, and that would be a very long simulation. There are however ways to link different simulations. In the paid world, IESVE has the MicroFlo CFD module which can be used independently to understand internal or external airflow based on the same geometric model. To remain free and open source, you could do something similar with EnergyPlus and OpenFoam, though significantly more effort would be involved. Like I said though, I don’t think CFD is really needed for what you are after.
