<DIV><SPAN class=370221814-25062009><FONT face=Arial><FONT size=2>I have a
heating only space with forced ventilation unit heaters. I've tried
modeling this space with and without baseboard heaters. When I add
baseboard heaters with the unit heaters, my annual heating <SPAN
class=246451214-26062009>consumption</SPAN> triples.<SPAN
class=246451214-26062009> I was not expecting this to have a drastic
impact on the natural gas usage.</SPAN> Does this mean that my model
without the base board heaters is <EM>not</EM> meeting all of the heating
loads? I've checked the equipment size against the peak demand and it
seems adequate<SPAN class=246451214-26062009> and the AHU schedule does not
indicate any hours outside the equipment capacity</SPAN>. <SPAN
class=246451214-26062009>What is causing the apparent change in load between
these two models?</SPAN></FONT></FONT></SPAN></DIV>
