The issue that I’m facing is that the direct evaporative cooling isn’t able to satisfy all the cooling load hours so I have supplemented the cooling with a DX system that has an Appnedix G (EER) rating. I’m not sure if this is the right way to handle this or if I should just have unmet cooling load hours, but I feel as though the USGBC will come back and want the cooling hours to be satisfied for both the design and baseline building. I was curious if anyone has had a building like this that they have submitted for LEED and what they did or how the USGBC commented and would like the model to be designed. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='color:#87C139'>James M.
