In addition to what Carol said, make sure you keep Sections G3.1.2.5 and G3.1.2.8 in mind. Of course, G3.1.2.5 only refers to Ventilation air, but the way I interpret that is that I keep airflows in my baseline and proposed models the same.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D">I’m not too fond of G3.1.2.5, because I immediately think of designers who want to meet the increase ventilation Credit in LEED. The increased ventilation
obviously causes an increased load on the system that would not be there otherwise (i.e. in a “baseline” case). So I personally feel that if a project is pursuing that credit, the baseline model should be based on 62.1 requirements, and the proposed model
should include OA quantities as designed. Regardless of how I feel, I still follow the Standard.<o:p></o:p></span></p>
