Air permiability Value in part L2 calculations

[kokaka]

I am looking to change Air permeability value from 10 to some other number.
After finishing the building in Model IT module I came down to VE-compliance Module to perform Part L 2 calculations. I choose Part L2 (2006) regulations and SBEM as method. Could some one let me know from this point where can I find the Air permeability value option and change it to required value?

Cheers

I'm sure this would be covered on the VE-SBEM training course that IES provides...

anyway you can edit Air Permeability at Room Level in VE-SBEM on the Building Regs tab of Room Data.

If you are using Apache DSM method you will find the Global Air Permeability value on the Building Details tab of Building and System data.
