[Bldg-sim] Window

Umit,

Addendum A removes that statement about uniform distribution, but does not change the area limits. As of April 2007 a design team may use addenda, but you must apply it to the entire LEED submittal (not necessarily all of the addenda, you can use just one if you like, as far as I know)- so you need to read all of Addendum A and follow all of its changes if you want to avoid the area distribution nonsense.

You can find the addenda here: http://www.ashrae.org/technology/page/132 

If there are other modifications to the 40% area limit I don't know of them.

Dear all,

I simulate an office building from ASHRAE Table G3.1 I read that "Vertical fenestration areas for new buildings and additions shall equal that in the Proposed design or 40 % groß above grade wall, whichever is smaller, an shall be distrubuted uniformly..."
My office building has in reality almost 80 % fenestration area.
my first Qeustion is;
1)in Proposed and Baseline design the fenestration area must be same or not?
2)in both cases should window area be less than 40%?
3)I read from this email group that 40 % fenestration area requirement not aplicable anymore ? is that right?
