Infiltrations definition ACH

Hello there,

I have a question around the infiltrations. I’m using the HB Apply Absolute Load Values to define my infiltration as constant value defined by a ACH.
When I look for the infiltrations within the IDF extracted file, the only infiltration value which appears is defined as a Flow per Exterior Surface Area (m3/s/m²). See the attached image.
I’d like to know how Honeybee works here ? Does it always convert the ACH infiltration input as a Flow per Exterior Surface Area ? No matter how the input is defined ?
What would be the best way to define a constant infiltration value over the year (in ACH) ?

Thanks in advance !

Max!
