I'm working on stadium in Australia. For compliance with ASHRAE 90.1-2010, the window systems (frame + glazing) have to comply with the mandatory provisions (5.4) in ASHRAE 90.1-2010.
The architect has selected window systems which the air permeability has been tested according to EN 1026/12207 class 2 (we have received the certificate showing this).
Is the EN standard acceptable for compliance? As the stadium is in Australia, it has to pass our local codes and we only need compliance with ASHRAE 90.1-2010 to get the LEED rating. If the EN standard is not acceptable, how should we proceed?
