Quantitative methods for HVAC system zoning?

The Manual Zr from ACCA is helpful for offering general guidelines for zoning rooms in a house, but I am wondering if there are any more concrete methods to figure whether a house needs zoned systems or not.
I understand that every house is a unique scenario and it depends on climate, orientation, amount and placement of windows, and many other things, but does anyone follow any quantitative guidelines to decide if you zone a system or not?
