Hi all

I have a question in relation to Core Performance Guide for advanced
buildings. 
I am looking at 2009 Core & shell office building and I want to go down
the Advanced Buildings Core Performance Guide Route.

Section 2.6 Fenestration Performance states that for buildings with
window and glazed door area greater than 40% of the gross area of
above-grade walls.............energy modelling must be conducted to
demonstrate equivalent performance.

What is meant by this statement, does this mean that you have to go back
to the performance rating method according ASHRAE 90.1 Appendix G?  Or
does it mean a more simple model where you check that heat loss, solar
gain and light transmission is equal or less with a building which has
say 60% glazed area compared to the Criteria set out for glazing in
table 2.6.1 for 40% glazed area?

Any thoughts on this would be appreciated

Thanks
