Thanks all. That's exactly the information I was looking for

That's correct - in 90.1-2004 Table G3.1.5c in the baseline column
states that the SHGC(all) value should be used for all fenestration.  As
someone else mentioned 90.1-2007 has removed the SHGC(north) values.

 

Best Regards,

I was recently told by USGBC reviewer to use SHGC all value for all
orientations, all rotations (in other words, ignore north values).

ASHRAE Appendix G states that the baseline building glazing should
conform with the 90.1 minimum standards. This is differentiated between
north and other orientations.

 

Therefore my baseline building has low-performance glass on north facade
and higher-performance glass on other facades.

 

My question is when rotating the baseline building during performance
rating method, should the glazing be re-assigned? Ie) should each
rotation meet 90.1 standards or only when the building is in its
original orientation.

 

I'm sorry this isn't a strictly an equest question (equestion?) but I'm
sure lots of you have encountered the same problem.

 

Cheers
