color:#1F497D'>Simulating an energy recovery unit which serves six air handling
units. I suppose this is simply enough, I split the total cfm into
percentages for each unit and incorporate into each unit’s heat recovery,
yes? Is there any way to include additional heat from the energy recovery
unit? Perhaps split the total heat into percentages and include this in each
unit’s heating capacity. How about variable frequency drives on
supply and exhaust fans for energy recovery unit? Perhaps this could be
modeled as a 10% reduction in the fan power similar to occupancy sensors on
lights? Regarding LEED, would usgbc need a credit interpretation request
for something like this or maybe just mentioning it as a default overridden in
the submittal would suffice. Would anyone who has encountered this care
to chime in? Any suggestions would be forthcoming. Thank you.<o:p></o:p></span></p>

<p class=MsoNormal>Dear all,<br>
<br>
When I model a one-floor building in eQUEST, I found that adding the
"lay-in acoustic tile" ceiling (no insulation added) will cause the
peak load through roof to zero. When eliminate the ceiling, a large part of the
building heat flow will go through the roof.<br>
<br>
I also tried several buildings. When added ceiling, then the heat flow through
roof turns to zero. Does anyone have an idea why this happens? <br>
<br>
Thanks a lot.<br>
<br>
Regards,<br>
<br>
David<o:p></o:p></p>
