The exhaust system will operate separate from the packaged unit and the proposed case includes a fraction in the operation schedule to reflect DCV operation. That schedule doesn’t affect the package unit except it will have less heating/cooling load due to the DCV. I don’t see the DCV affecting the fan sizing or operation of the baseline packaged unit. The packaged unit is constant volume. So, the LEED comments refer to identically modeling the base and proposed systems, for fan volume and fan power, on this exhaust system. I’ve worked out matching the exhaust system well enough, but now I’m wondering if I need to match the supply also. The simplistic answer would be “yes”, even if the comments refer only to the exhaust system I am concerned a cursory review may still not be happy with the supply fan volume/power not matching. I think not matching is valid and it is definitely more favorable, so that’s what I’d rather do.<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:.5in'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:.5in'>The baseline system has a larger supply fan, and will have a greater heating/cooling load (no DCV). The proposed system will have a smaller supply fan and a smaller heating/cooling load. I think the base case fan sizing is more accurate since it is based on the actual loads of the baseline building. If I use the fan sizing/power from proposed, the project will take a big hit. Basically I think this means in theory that not matching the supply fans, even though they are tied to the exhaust DCV, is an accurate estimation of savings from baseline to proposed.<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:.5in'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:.5in'>Right now I’m inclined to leave the supply not matching, and provide an explanation.

Revise the Proposed and Baseline model so all independent fan systems of the HVAC systems are modeled identically between the Proposed and Baseline model.
