<DIV><FONT face=Arial size=2><SPAN class=675361213-18082008>My system involves
first a CDQ which is supplied with 100% outdoor sir which heats and/or cools the
air and supplies it to two air handlers, which supply VAV boxes. I have modelled
this using a CDQ (Variable Air Volume) unit which supplies the two Air Handling
Units (Power Induction Units).</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=675361213-18082008>I am now creating my
reference case using parametric runs and based on the Model National Energy Code
(Prescriptive Compliance), and using the article Performance Compliance for
Buildings - May 1999. The Zone References can only be AH1 - Single Zone
(constant flow) or AH2 - Multiple Zone (variable flow) according to the
Compliance. I was wondering if anyone has suggestions on what reference case I
should based each of my three HVAC systems?</SPAN></FONT></DIV>
