We have a campus project which includes exterior lighting added within our scope and on our site to illuminate an adjacent private drive and an adjacent parking lot. (all campus properties). Neither drive nor parking are included in the LEED project boundary as they are existing and not used by occupants of our project. We will meet the interior escape, exterior uplighting and LPD requirements for this credit. The issue is the light trespass component. I understand the LEED lighting boundary can be extended as per CIR 10236. However, extending this by 5 feet does not help us (lighting the street and parking is the goal) and documenting trespass around the entire campus boundary would be irrelevant and nearly impossible. So, my question is whether we can use the third provision of CIR 10236 to extend the lighting boundary to include just the parking and just the property across the drive as they are all campus lots. Or, would it be wiser, to make a case to omit this lighting from the site photometrics altogether as it is essentially meets the same intent as the exemption for municipal street lighting. (which is, of course, safety)
