<p class=MsoNormal>Hello eQuest Users,<o:p></o:p></p>
<p class=MsoNormal>I am using eQuest 3.61e and modeling lighting improvements
through a parametric run. The only component that I am changing for the
parametric run is the Lighting W/ft<sup>2</sup> for the entire building.
My boilers and water heaters are located inside the building in a mechanical
zone (which also gets the lighting density reduction). My parametric run
is showing fuel losses in my space heating (boilers) and domestic hot water categories
on the order of magnitude of 2% of the building fuel use (2,460 therms).
If I change the zone of the boilers and water heaters to outside, the fuel use
for this parametric run is not affected. I understand that there may be
additional tank losses due to a smaller heating load from the lights but, in
reality, this penalty seems excessive.<o:p></o:p></p>
<p class=MsoNormal>Can anyone verify that this is appropriate or is there an overall
tank U-value input that I can adjust to eliminate this loss? I would like
to avoid keeping the boilers outside if possible.<o:p></o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
