The people load is too high. ASHRAE 62.1-2010 Table 6-1 has an occupancy density of 8 people per 1000 ft². 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. </span></div><div class="yiv3456722412MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri", "sans-serif"; font-size: 11pt;'> </span></div><div class="yiv3456722412MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri", "sans-serif"; font-size: 11pt;'>Hope this helps

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. The store is considered as a "dry store". I am not
placing any big commercial refrigerator for meat. </span></div></div><div><div style="background: white;" class="yiv3456722412MsoNormal"><span style="color: black;"> </span></div></div><div><div style="background: white;" class="yiv3456722412MsoNormal"><span style="color: black;">I have some problems with the infiltration and ventilation. The more I read about these topics and try to apply the information to the model, the more confused I get over and over again. I am not sure if I have introduced the right data to eQuest. I used 0.161 ACH for infiltration from the following source in page 32 (infiltration) in the internal loads for the space properties:</span></div></div><div><div style="background: white;" class="yiv3456722412MsoNormal"><span style="color: black;"> </span></div></div><div><div style="background: white;" class="yiv3456722412MsoNormal"><span style="color: black;"><a

The ventilation is another issue that I do not have any clue. What should I put and where should I put it? These are the only problems, with my limited experience, that could be causing some problems. I am attaching the INP and the PD2 files plus an AutoCAD file, because I drew the floorplan and imported it to eQuest. Please, any help will be greatly appreciated.</span></div></div><div><div style="background: white;" class="yiv3456722412MsoNormal"><span style="color:
