Dear all,

I would really appreciate some insight on infiltration with respect to eQUEST.

The
air change rate of the building at a pressure difference of 50 Pa indicates the
level of air tightness. eQUEST
allows entering the number of infiltration caused air changes per hour at a
reference speed of 4.47 m/s. In that case, do we just enter the ach at 50 Pa in eQUEST, then how does the wind factor effect? Am kind of confused.

Also, I would highly appreciate if anyone could share what are the ballpark infiltration levels in commercial (small) buildings in US and Canada.

Thanks,

Shalini
