this is a strict business decision involving sustainability and TCO.  if it
takes one watt of mechanical to transfer heat away from every watt delivered,
whereas ambient air with good-enough filtration will let one watt of roof fan
transfer the heat away from five delivered watts, then it's a no-brainer.  but
as i said at the outset, i am vexed at the moment by the filtration costs.
