Ditto, for what it's worth!
I had a project with a 2-story entry/atrium space with a glass exterior in a very cold climate... actual design used a heavy amount of baseboards along the perimeter in addition to FPVAV's with reheat.
The baseline system serving that space was a fan-powered box (System 6) that had to autosize pretty big to keep up with the heating loads.
