Sorry for the late reply.
I just have 6 hives, all with SBB's. They all also have reasonable wind barriers. However, having just a few hives, can afford to micromanage. Therefore, I leave them open, even in the coldest of cold. When it gets windy, however, will slide in the bottom to the SBB's. It's usually only for a day or so, until the cold front passes. The reason, is because of what's usually mentioned here and in literature, that the cluster has a harder time in wind than with cold, per se.
No scientific data to present, sorry.
