Hi Chris,<BR>
<BR>
In most building energy simulation programs including DOE-2, It is impossible to define two different HVAC systems in one thermal zone. Therefore, it is sometimes useful to seperate one actural zone into two thermal zones(e.g. interior zone and perimeter zone) using an articificial boundary like 'air wall' when an actual one zone in existinfg building has two different systems, for example, VAV system is for a interior zone, and fan coil unit is for a perimeter zone. <BR>

An important corollary I want to emphasize is that models ultimately serve a purpose, and that it’s important at the beginning of any project to identify that endgame. Sometimes it’s getting LEED points, sometimes it’s advising new or retrofit design for existing envelopes, HVAC, and/or lighting, sometimes it’s because there’s academics who simply want a model they can pick up after you to tweak to perfection as time goes on… </SPAN></P>

<P class=ecxMsoNormal><SPAN style="COLOR: black; FONT-FAMILY: 'Arial','sans-serif'">When you are bill matching there are not magical ways of doing things. You pretty much have to put what's in the building in your model. Those things you can control. The tricky part is to figure out how the building is really being operated and to get the most accurate weather data you can for your site.</SPAN><SPAN style="COLOR: black"></SPAN></P></DIV>

<P class=ecxMsoNormal><SPAN style="COLOR: black; FONT-FAMILY: 'Arial','sans-serif'">While modelling existing building (with calibration to utility bill), do you model every VAV zone or lump similar ones together?
