color=#0000ff size=2>I am modeling a brand new multi story museum in eQuest in a
4 season climate. The Museum has several atriums, some two story and some three
story. I have been making the atriums vertically multizoned, removing the floors
and ceilings, and creating airwalls between the atriums levels. I
have conditioned all bottom atrium floors, conditioned the 2nd floors of the 3
story atriums, but have left the top floors of ALL atriums
unconditioned.</FONT></SPAN></DIV>

90.1-2004 is the base building. This requires eQuest sized airflows for a 20 Deg
