<p class=MsoNormal style='text-autospace:none'><font size=2 face="Courier New"><span
style='font-size:10.0pt;font-family:"Courier New"'>I’m modeling a
multistory office building located in <st1:State w:st="on"><st1:place w:st="on">New
York</st1:place></st1:State> using eQUEST. The building has a heated basement
(no cooling) and six conditioned floors (heating and cooling). Cooling is done
via air-cooled DX units and a packaged VAV with reheat distribution system. Heating
is done using boilers and a hot water loop feeding the reheat coils in the VAV
box and baseboards along the perimeter. The schedules are eQUEST defaults. I am
not sure what I am doing wrong, but I am getting a significant cooling load in
winter. I am using OA temperature controlled economizer and compressor lock-out.<o:p></o:p></span></font></p>

<p class=MsoNormal style='text-autospace:none'><font size=2 face="Courier New"><span
style='font-size:10.0pt;font-family:"Courier New"'>One other strange thing that
happens with this model is that both fan energy and demand go up in the winter.
One should think that in the heating mode the airflow is set to minimum and the
temperature is varied to meet the load. Therefore the fan energy and demand
should be lower in the winter. However, the numbers I am seeing show that the
demand for the fans is about 50% higher in the winter and the fans energy use in
January is almost 4 times higher than the one in August. I have played with the
night controls for the fans, but that does not help. If I select the “Stay
Off” control instead of “Cycle On Any” I am getting rid of
the cooling in the winter, but I am getting weird heating numbers in the summer.
In June and August I get some gas use (???) for space heating, but none in
July. I do not know what I am missing, but this does not seem right.<o:p></o:p></span></font></p>
