Maybe I confused, could you explain me a bit why the calculation of fresh air for residential different from fresh air for commercial building? Thank you.
No problem. ASHRAE 62.2 is for low rise residential buildings. It only takes into account OA = 0.01 sqft+7.5 (Nbed+1) for 2010 and OA=0.03 sqft+7.5(Nbed+1) for 2013. This usually depends on the authority having jurisdiction. County and location requirements are necessary to follow either ASRHAE 62.2_2010 or 2013. This calculation is mainly for Commercial applications where the layout is different. The apartment units can be utilize in high rise buildings (10 floor building for example) where the conditions are different than residential (no more than 3 floors). In this video, we utilized the IMC (International Mechanical Code) which usually based in ASHRAE 62.1. I will make another video indicating ASHRAE 62.1 for apartments Part 2 for more examples. I hope this helps
