program without simulating a system, 2) adjust the constant zone temperatures specified in LOADS, 3) simulate the thermostat schedules (but not the equipment), and 4) tabulate energy consumption by ZONE (or group of ZONEs). SUM is not a miscellaneous SYSTEM-TYPE

<p class="MsoNormal">I have a building with more than one kind HVAC system. I have the first floor with VAV system, and the second floor only has ventilation fans running. So I made all the zones on Second Floor unconditioned, and choose SUM as air-side HVAC
system for second floor. However, the Space Cool of no VAV for second floor is even higher than that of the whole VAV, which does not make sense to me. <br clear="all">

<p class="MsoNormal">Do you know how the eQuest calculate Space Cool? Should The VAV energy consumption be Space Cool+Vent. Fans shown on the simulation output?<u></u><u></u></p>
