Hello,
I am Manasa Lingamallu pursuing 4th year at Building Science, IIIT
Hyderabad. I am currently working on developing a tool that calculates
Envelope Performance Factor (EPF) using Trade-off option. In this method I
am supposed to use Floor area factor (FAF), for which I am unable to find
its definition in ASHRAE.
Please could anyone help me by defining it and also by suggesting
method to calculate FAF.

Thankyou.
