The Project Boundary is the same as the LEED Project Boundary as defined in Minimum Program Requirement #3 and as documented on the Project Information Form. All lighting within this boundary must comply with this credit's requirements.
The Lighting Boundary is located at the property lines. It can be modified to extend beyond the property lines under certain conditions, for example when the property line abuts a public area. (Be sure to provide justification for any modification made.) It is used only for the purposes of the trespass calculation, based on the light emitted by the luminaires within the LEED project boundary.
Often the Project Boundary and the Lighting Boundary may align, but when they do not, make sure to include in submitted documentation an explanation of how the two differ.
