Hello there
What does this mean :
Ensure that no credit is taken in the proposed case for lighting reduction on tradable surfaces"
Does this mean if the LPD for facade lighting for a designed building is lower/more efficient than the stated max LPD in ASHRAE i,e 2.2 W/m sq, this lower value cannot contribute to the LEED points collected under this credit
Hoping this can be explained too:
additional lighting power allowance cannot be claimed in the baseline model for surfaces which are not provided with lighting in the actual design
Thanks and look forward

I believe that first statement should read "non-tradable". So yes no savings can be claimed for non-tradeable lighting. Basically your non-tradable wattage must be identical in the Proposed and Baseline models.
Make sure that the lit areas in both cases are identical. If a corner of a parking lot is not actually lit in the design it cannot be included in the baseline.
