that's about 1.3 cfm per sqft. and it may work. My feeling is your on the boarder line. and when your paying big bucks to host an event. i don't want to hear "Captain the AC is doing all it can" when im hot. :gah
but taken into account you didn't included the structure so the rest remains to be seen. I built out many conference rooms and 2 cfm per sqft is what has been consistent and has worked for me.. because this is a new add on and not existing, If this owner is smart he should have the architect and ME, design a cost saving structure. otherwise your spinning your wheels
Yeah agreed! Recommend hiring an Arch and ME. Us mechanical engineers aren't getting any work .
