<p class=MsoNormal><span style='color:#1F497D'>Thank you all for your input. The
building exhaust systems will be separated into 4 components: general exhaust,
fume hood exhaust, snorkel exhaust and biological safety exhaust. The reason
for this is for cross contamination considerations in the non-general exhaust
systems and the goal to achieve total energy recovery with a energy recovery
wheel. In addition, the systems will have different static pressure
requirements. Yes, I am implementing airside heat recovery for the general
exhaust system, and considering application for the fume hood system depending on
feasibility of a system with no cross contamination as required by the owner. <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>Bill - I am planning on having
variable flow at the system level for both the general exhaust and fume hood
exhaust systems. This is precisely why I was concerned with the software's
ability to model this situation. Thank you for your advice.<o:p></o:p></span></p>

system-level variable flow exhaust system(s)? If so, I don’t think it
will work if you model zonal exhaust air flow tracking. (Someone please correct
me if you have determined otherwise.) </span><span style='font-size:10.0pt;
font-family:"Arial","sans-serif";color:navy'>One way you can model variable
hood exhaust and allow for energy recovery is to use a MIN-AIR-SCH at the
system level to vary the percentage of outside air, in combination with
MIN-FLOW-SCH at the zone level, provided your system is VAV. I would add total
system supply flow and O/A percentage to your hourly reports, so you can see
what the system is doing throughout the year.<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>I’d like to add to
Vikram’s comment about CAV hoods. I’d encourage you to
advocate for VAV hoods if the zone’s hood CFM is 2ACH or greater.
There has been a lot of progress in recent years in working towards lower occupied
and unoccupied ACH minimums, and 2 ACH may be within reason for many clients in
the coming years. If VAV hoods are in place, and the capabilities of the
air valves allow, the system would be able to turn down to a lower ACH minimum
and garner your client savings.<o:p></o:p></span></p>

above you can specify airflow tracking for exhaust air streams on a thermal
zone basis – there’s a good help section on what the different
tracking options do. It’s my understanding that this was put in
specifically for fumehoods. Set your max flow rate here and set up a fraction
schedule to determine flow rate. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#0000B4'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#0000B4'>One thing you might want to
check up on is the fumehood density. If the lab is very fumehood intensive,
then it might make sense to go with the VAV hoods. However, if it’s a
ventilation driven lab (as opposed to an exhaust driven lab), you might as well
have constant volume hoods. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#0000B4'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#0000B4'>For instance, if your EHS
requires 6 air changes per hour in a 10 foot high 10,000ft2 lab, your supply
cfm = 10,000 cfm. Lets say you have 10 x 6’ wide fumehoods with 800cfm at
max sash height (18”). That would give you 8,000 cfm. So having VAV
controls on the hoods is not going to reduce your airflow unless you ramp down
to below 5ACH during unoccupied hours. <o:p></o:p></span></p>

<p class=MsoNormal>I am about to begin an energy model for a large university
lab project that includes about 150 VAV chemical fume hoods. The building
systems will include a true VAV exhaust system, not a bypass system. Please
advise how this can be modeled using eQuest. Thank you in advance.<o:p></o:p></p>
