I'm happy to look at your inp file, but I can't open it with eQuest. My initial guess is that you have a pilot on all summer, or that your boiler is cycling at an inefficient part load ratio in response to small demands.<br>

Hello,<br>
<br>
I am modeling an existing building with multizone air handlers with chilled<br>
water coils for cooling and hot water coils for heating. The hot water is<br>
generated by a gas furnace. I am seeing some discrepancies in my gas usage<br>
from actual to the simulation. In the actual building, the gas usage is<br>
only high in the winter months (the building is in the south) and is next<br>
to nothing in summer months. I have tried all the various methods of coil<br>
control under the "heating" tab and cannot get the simulation to reflect the<br>
real life usage. Does anybody have any ideas on how to control the heating<br>
better? Representative files are attached.<br>
