Working on a 160,000 SF retail store. This credit seems to be very tricky and unclear how it may apply to a "big-box" retail situation, such as Wal-Mart. The prototype is large box retail center flanked by shipping, receiving / office spaces on one end and ancillary shops / small retail spaces at the other. Does anyone know how this project type is calculated and justified for this credit?

This credit is not easily achieved under NC. In an office setting, the most common strategies to earn the credit are to have 50% or more of the occupants within a perimeter zone that has many operable windows, or a raised floor/ underfloor ventilation system (UFAD) with one floor vent per every two occupants.
It's hard for me to imagine how this credit could be achieved in a retail setting with the NC requirements - half the occupants of individual workstations need access to their own individual thermal control. For the "multi-occupant spaces" each group would need to be able to adjust the temp or ventilation of their particular area.
You'll probably want to look at the EQc6.2 requirements under LEED for Retail NC which addresses primarily the office and administrative areas. It is expected to be available late in 2010: http://www.usgbc.org/DisplayPage.aspx?CMSPageID=1734
