Lighting Boundary - I am confused

Hello to all LEED user community,

My project is a building within a bigger site property. The LEED Boundary is not all the site, but the building with it's outside parking area.

The project aims to be compliant with the BUG Method Option.

1. In stis case the LEED Boundary is the same with the lighting Boundary?

Could it be that the Lighting boundary is the Property Line?

2. What does the lighting boundary mean? Does it mean that all lighting fixtures included in the Lighting Boundary must be compiant with option 1?

 

Thank you

I don't understand all of your questions.  Below are the definitions I used on another post. The Project boundary is the same as shown in every other credit. All lighting within the project boundary must show compliance with this credit's requirements. The Lighting boundary often has a lot of overlap with the project boundary. But they are separate. The Lighting boundary can be moved out at roadways or to the entire campus. The lighting boundary exists for a single purpose. As a line to measure spill light at. 2. All lighting within the project boundary must be compliant.  Compliance is measured at the lighting boundary.  This is a lot easier for a campus project since the lighting boundary can be far from the project boundary.
