Thanks Nick and Brian.
Do you mean for building energy modeling, it is not necessary to input exterior 
lighting? If I try to get energy saving credit from exterior lighting, how 
should I input baseline value?

The phrasing is a little off for the wizard approach...
 
If you want to enter the exterior lighting wattage prior to detailed edit and 
not have to correct it after the fact, divide the sum of the installed exterior 
watts by the square footage of the shell you are entering the W/SF value in (the 
exact area to use for this is displayed on the 2nd shell screen).  Enter that 
W/SF figure in only one shell if you have multiples.
 
If you follow that, you’ll have the exact installed watts entered correctly.
 
Total exterior area lit does not come into the equation.

You can do that -- or wait and add as a direct load to the electric meter in 
detailed edit mode (which is what the wizard is going to do anyway).

Dear All,
How should we modle the exterior lighting? If I know the total exterior lighting 
wattages, should I divide the total outdoor area to get watt / sq ft for wizard 
screen 23 inputing? 

Thanks,
Lisa Li
