Light Pollution Reduction for Multiple buildings

Hi,

We are working to get LEED v4 BD+C Gold certification for multiple buildings (Office Tower G+5, Retail G+1, Canteen building G+1, Mosque GF, Service Block G+1). All buildings are located at same site and landlord/owner is same for all the buildings.

we've targeted separate certification for each building as well as LEED Boundary marked separately.

Regarding Light Pollution Reduction, our doubts are as follows.

1. Whether we can use whole site as lighting boundary to check the compliance? (landlord/owner is same for all the buildings)

or

2. individual building has to meet the compliance separately

3. If Yes for Question 1. Whether we can submit the light simulation report (while site) for all building's submission.

4. Is there any CIR stating the same situation?

Thanks..
