62.1 is concerned with people, who need ventilation (supply / intake).
For typical buildings, you may not need separate exhaust fans, because that
amount can probably exfiltrate through cracks. Supply and exhaust fans
can be used in tandem if the building is fairly tight (no leaks).<o:p></o:p></span></font></p>

depending on the warehouse storage, MEP team recommends 5-8 Air Changes per
Hour by thumb rule for exhaust and air intake is assumed by infiltration by
windows, open doors etc.. But this number I haven’t find in ASHRAE,
please give me reference.<o:p></o:p></span></font></p>

62.1-2004, Table 6-1 for warehouse category says to have 0.06 cfm/ft<sup>2</sup>,
is this number defines to intake or Exhaust? If it is exhaust, it is too small
