I have NEVER heard of WWR ratio including below grade walls.  California Title 24 never has.

I know this question has been asked before but I could not find a related thread.

 

90.1 states that the WWR is based on the gross wall area and the definition of gross wall area includes below ground walls as well as above ground walls..  Including the below grade walls can make a significant difference in the WWR for typical urban high rise buildings with a number of below grade parking floors.  

 

Can someone confirm that the WWR calculation is based on above grade wall area plus below grade wall area?
