i am also reminded that there is a cir from 2007 that addresses how to 
simulate the exterior lighting loads.  tradeable surfaces are to be the 
same as designed in the proposed model and the maximum allowable in the 
baseline model.  nontradeable surfaces though, per the usgbc cir, are 
energy neutral & will have the same lpd in both the proposed and 
baseline models.  if i recall correctly without looking it up it should 
be the nontradeable uses maximum 90.1 allowable in both 
proposed/baseline models.  need to check though.
