<!--/htdig_noindex--><!--beginarticle--><PRE>I have used the DCV ventilation method with OA from the system and it
has worked great, as long as you have inputs in correctly under the zone
outside air & exhaust. If you have inputs under the zone incorrectly
then the OA control on the system will be overridden by the inputs under
the zone.
Inputs in the model would be something like this to get it to work:
-Air side HVAC System under outdoor air - vent & economizer:
-Under Min. outside air (ratio)- set at whatever, such as 0.10
for 10% OSA (if using an economizer the minimum must be set at least to
0.001, or the economizer feature will not work in the model).
-Under Min. OA Method - I always use DCV Return Sensor.
-On each Zone under the system under Outside Air & Exhaust:
-Under Outside Air Flow/Person - Input CFM required by code or
usually 15 to 20 CFM per person.
-Under Outside Air Flow - Leave this blank.
-Under Outside Air Changes - Leave this blank.
-Under Outside Air/Flow/Area (CFM/FT2) - Normally I input 0.06
here, which is typically the amount required by the code.
As long as you have your hourly occupancy schedule set up correctly with
the % of the number of people that are in each zone then these inputs
have always worked for me. The Outside Air entering the system will
vary down to as low as 0.06 CFM/FT2 of the area of the applicable zones
depending on how many people your occupancy schedule shows you have in
each of the applicable zones that you have under the HVAC air system.
The Outside air reduction will, of course, also always be limited by the
amount of exhaust CFM that you have input under the zone. Be careful
with what you enter under the zone regarding the CFM of the ventilation
and the exhaust, as the program will always override what you enter
under the system by what you have entered under the zone.

James on this one. I can see changing lighting or equipment schedules to capture
ECMs but changing occupancy schedules makes no sense unless you’re modeling
telecommuting or 4-day work week. You can capture DCV savings in eQUEST by
selecting DCV as the Minimum OA Control Method for the system and having an
occupancy schedule with a varying percentage (not 100%) during occupied hours.
Using the same occupancy schedule, the model with DCV will heat/cool less OA air
and show savings.<o:p></o:p></SPAN></P>

record, the occupancy schedule refers to the people present within the
space. For instance, a space within the baseline (not required
by ASHRAE to have DCV) would have the max number of occupants for the
entire occupied-mode schedule; however, the proposed would have the max number
of people for only as many hours as submitted in the project
narrative for FTE usage of the space, and a minimum number of people (or no one)
for the remaining occupied-mode time. Thus we create an occupancy (people)
schedule for the space. During the unoccupied mode the fans would cycle as
required with no people, no lighting (automatic shut off), acting on
the heating & cooling loads. We would not install DCV if the
occupant loads didn't change during the occupied mode.”<o:p></o:p></SPAN></P>

me if I’m reading your email wrong, but are you saying that your occupancy
schedule in the proposed design does not match the baseline design? This is
strictly prohibited in App G I thought… You can change schedules to take
advantage of non-standard ECMs like DCV, and automatic lighting reductions for
the use of occupancy sensors (in rooms NOT already required to have them by
code). But having a conference room 100% occupied from 7am-6pm in the baseline
model and only 100% occupied from 9am-noon in the proposed model is not a valid
way to demonstrate savings from DCV, since there will be energy savings related
to the people latent/sensible production that has nothing to do with DCV. Don’t
you have to create a minimum outside air schedule to demonstrate DCV savings? If
you have received credit for simply reducing the Occupancy Schedule in the
proposed model, that is very interesting…<o:p></o:p></SPAN></P>

occupancy schedule refers to the people present within the space. For
instance, a space within the baseline (not required by ASHRAE to have
DCV) would have the max number of occupants for the entire occupied-mode
schedule; however, the proposed would have the max number of people for
only as many hours as submitted in the project narrative for FTE usage
of the space, and a minimum number of people (or no one) for the remaining
occupied-mode time. Thus we create an occupancy (people) schedule for the
space. During the unoccupied mode the fans would cycle as
required with no people, no lighting (automatic shut off), acting on
the heating & cooling loads. We would not install DCV if the
occupant loads didn't change during the occupied
mode.<o:p></o:p></SPAN></P></DIV>

that’s an interesting statement in itself – modifying occupancy schedules has an
impact on the mechanical cooling (not just the cooling associated with reduced
ventilation air), which isn’t really fair. Was that approved by

class=MsoNormal>It has come to our attention from a posting on the eQuest
list-serve that a fellow energy-modeling professional has been asked to model
proposed design and baseline design ventilation rates differently where the
proposed design model utilizes demand controlled ventilation. We have
searched the ASHRAE 90.1 documentation as well as the LEED reference
documentation and consistently find the requirement that baseline ventilation
rates be modeled the same as the proposed design, and that credit can be taken
for demand controlled ventilation.<o:p></o:p></P></DIV>

class=MsoNormal>We understand that large energy savings can be gained from
demand controlled ventilation and that in certain cases, 'gaming' of the system
could result in abnormally high ventilation rates for the baseline design, while
the DCV system keeps ventilation rates low in the proposed design, however, our
main concern is that energy modelers are being made aware of changes to
guidelines during the design review process. At this stage, the energy
modeler has already completed a significant amount of work in preparing the
proposed and baseline design energy models, and all associated documentation.
Changing the baseline design ventilation rates requires re-modeling of the
building and increases the likelihood that the project will have to challenge a
'rejected' result if the LEED reviewer is not satisfied with the energy
modeler's response and modeling changes.<o:p></o:p></P></DIV>
