    I'd recommend reading Architects Studio Companion.  It's easy to read (lots of charts & diagrams).  There's an entire chapter devoted to when to use each type of HVAC system.  I found the book very helpful; mostly for PPD.

    Good luck & keep studying!

    This is obviously a vast subject and difficult to answer here. I had to make 4.5 hours of animated content, plus 2 hours of other video content, plus countless flashcards and practice exam content to cover it. . . Water can cary heat and coolth farther more efficiently, so large buildings are more likely to use water. Hydronic systems also can be more efficient at heating (radiators) or cooling (chilled beams) because the air temperature doesn't have to be so warm in the winter or cool in the summer if your skin "sees" something hot (winter) or cool (winter). Pipes are obviously much smaller than ducts, so water systems often offer a better solution to historic preservation projects where you don't want to create a gyp bd soffit in a tin ceiling to hide the ducts. Lastly, if there's no fan in the room blowing air over the hot/chilled water in pipes, then radiators, radiant floors, and chilled beams are quieter than ducted systems and much quieter than fan coil units.
