Hi All,<br><br> As a new equester, i have very basic questions on air side input given as follows. <br><ul><li>I have seen in most of the project in the zonal Basic specification tab we put minimum design flow 0.5 CFM/SF, Outside/person is 20 CFM and if we have VAV then 0.3 for VAV. But ASHRAE 62.1 says that for office building it has to be 5 CFM/person + 0.06 CFM/Sqft. My doubt is why this difference is? what is the correct methodology for Air side input at zone level in proposed and baseline case?</li>
<li>What is the strategy for putting ACH in Air flow tab and outside air tab. How to do it correctly. One thing i have learnt from forum is that Zone level input overrides System level input.</li><li>Appndx G says the Ventilation rate should be same in proposed and baseline case so can i put ACH input in proposed and 20 CFM/person/0.4CFM/Sqft in baseline?</li>
<li>Please suggest any reading material to get better understand above problems?<br></li></ul><br>I will be highly thankful<br><br>Regards,<br><br><br clear="all"><br>-- <br><br><br><i><font style="font-family:arial,helvetica,sans-serif;color:rgb(102, 102, 102)" size="2">Javed Iqbal, LEED AP, CEA<br>
