[Bldg-sim] Calculating the exterior lighting power allowance for LEED 2009

This is more of a LEED question but the task has fallen onto the shoulders of the simulator.

I am trying to determine what areas should be included in the exterior lighting power allowance calculation.

For example, the project site plan clearly shows walkways and parking areas.  There are no specific exterior lights for the walkways, the parking area light poles also light the walkways.  My assumption is that the walkways should not be included in the calculation of the exterior lighting power allowance.  Is this assumption correct?

Another example.  A light over an exit door, with no canopy, also lights the walkway outside the door.  I assume that the this walkway should not be included in the calculation?  It seems to me that also including the walkway and setting the proposed lighting power to 0 Watts would be ‘double counting’ against the baseline exterior lighting power allowance?

Thanks for your insights!
