The people load is too high. ASHRAE 62.1-2010 Table 6-1 has an occupancy density of 8 people per 1000 ft˛. That would put your people load at 74 people not 138. The infiltration ACH rate is good however if the store has a vestibule the infiltration rate of the vestibule should be calculated and modeled. See ASHRAE vestibule infiltration formula for information. <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><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Hope this helps <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><div><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></b></p><p class=MsoNormal><b><span style='font-family:"Arial Narrow","sans-serif";color:#1F497D'>Michael Hupel</span></b><span style='font-size:8.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>, B.Tech, CEM, LEED</span><span style='font-size:8.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>®</span><span style='font-size:8.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>AP</span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>Senior Mechanical Designer<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><i><span style='font-family:"Arial Narrow","sans-serif";color:#002060'>Aegis Engineering Inc.<o:p></o:p></span></i></b></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>56 Pennsylvania Ave. Suite 18<o:p></o:p></span></b></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>Concord, ON L4K 3V9<o:p></o:p></span></b></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>(905) 761-1264 ext. 24<o:p></o:p></span></b></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>(905) 761-6949 fax<o:p></o:p></span></b></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial Narrow","sans-serif";color:#1F497D'>(647) 702-3316 cell<o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:Webdings;color:#1F497D'>P</span><span style='font-size:7.5pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>P</span><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>lease don't print this e-mail unless you really need to.<o:p></o:p></span></p><p class=MsoNormal><b><i><span style='font-size:14.0pt;font-family:"Calibri","sans-serif";color:#002060'><o:p> </o:p></span></i></b></p><p class=MsoNormal><span lang=EN-US style='font-size:8.0pt;color:#1F497D'>This message may contain information that is confidential and/or protected by law.

The grocery store is a small 9,217 sq.ft. with 138 people (approx) at the same time (67 sq.ft./person). The only loads that I am using are lighting and appliances.
