I usually model vestibules as separate zones, since they tend to have their own cabinet unit heaters to handle the infiltration and envelope loads. I often combine interior zones with little or no load (such as storage rooms) with adjacent zones. I combine janitor closets with adjacent corridors if that is where they pull their outside air from. Sometimes I do that with bathrooms as well but then the space-by-space lighting density (from Table 9.6.1, ASHRAE 90.1) gets trickier.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Regards,<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Bill<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Franklin Gothic Medium Cond","sans-serif";color:black'>William Bishop, PE, BEMP, LEED<sup>®</sup> AP </span></b><b><span style='font-size:10.0pt;font-family:"Franklin Gothic Medium Cond","sans-serif";color:#006600'>|</span></b><b><span style='font-size:10.0pt;font-family:"Franklin Gothic Medium Cond","sans-serif";color:black'> </span></b><b><span style='font-size:10.0pt;font-family:"Franklin Gothic Medium Cond","sans-serif";color:black'>Pathfinder Engineers & Architects LLP</span></b><b><span style='font-size:10.0pt;font-family:"Franklin Gothic Medium Cond","sans-serif";color:black'><o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:black'>Mechanical Engineer<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:5.0pt;font-family:"Arial","sans-serif";color:black'><o:p> </o:p></span></p><p class=MsoNormal><!--[if gte vml 1]><v:shapetype id="_x0000_t75" coordsize="21600,21600" o:spt="75" o:preferrelative="t" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f">
