Are you modeling DCV by changing the space occupancy schedule (SPACE:

putting all of your occupant heat gain in as a process load? I am gasping
to understand the validity of changing the people schedule.<o:p></o:p></span></p>

color:navy'>I’m with 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>

have the max number of people for only as many hours

a minimum number of people (or no one) for the remaining occupied-mode

please educate 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>

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 GBCI? If so, I guess it’s further
proof that there is still a lot of inconsistency in the review of EAc1. </span><o:p></o:p></p>

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>

margin-left:.5in'>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>

changes made to EA Credit 1 energy modeling guidelines should be made with
adequate notice to the energy modeling community.<o:p></o:p></p>
