<p class=MsoNormal>Hello fellow eQuest users. I am having an issue
modeling a system that is made up of an exhaust fan sequenced to a 100% OA
make-up air unit. Since we need to include cooling in the model of this
system I currently have it modeled as a packaged single-zone system with a
2-speed motor in it. I feel this is the best representation of what our
design system would be, after adding cooling to it. The problem is, I am
getting what seems to me to be overly aggressive ventilation energy and cooling
energy savings. The cooling energy consumption of my design system is
about 20% of what the code case is (code system is a Sys5, VAV with DX cooling
and fossil fuel boilers) and the ventilation energy of the design system is
only 33% of what the code case is. These seem to be unrealistically large
energy savings, and I feel USGBC will not accept them. Does anyone have
experience with a system like this?<o:p></o:p></p>
