Now, I`m modelling high-rise building to study about airflow in the building.
To get a exact values in airflow Crack flow coefficient value is important.
manual recommend AIVC technical note 44 but, I want to apply window product`s real value.
on the product`s real specification, unit of air infiltration value is ' m^3/h m^2 at 100Pa '
so if
the product`s air infiltration value is 20m^3/h m^2 at 100Pa
then use power law equation ' Q=C(△P)^n '
C = (20m^3/h m^2)/(100Pa)^0.6 and C = 1.26 m^3/h m^2 Pa^0.6
and divide it by perimeter of window
Is my method right?
thank you for reading my question and I`m waiting your answer
have a nice day.
