<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Franklin Gothic Book",sans-serif;color:#1F497D">Let me start off by saying I may not be what you consider an “expert” but have completed several submissions to LEED over the past few years, and
I am assuming that is why you are modeling this building. Without knowing the square footage it is hard to determine if that is the correct baseline system. There are exception to the baseline systems that may be beneficial for you to entertain, G3.1.1 has
the list. There are specific requirements outlined for the baseline cooling systems that must be followed, G3.1.3 which includes an air temp reset schedule. You must also remember that whatever you chose to model for cooling in the baseline must be modeled
identically for the proposed system if the space is not cooled.<o:p></o:p></span></p>
