I am working on a LEED C&S project for a Building within a large business campus. In relation to the light trespass of the external lighting I need to determine the site and project boundary. The owner of this building also owns the whole campus. The car park that serves this LEED building is surrounded by existing car park. Therefore the new car park will be an extension to the existing scheme. Can you please clarify how I might define the site and project boundary for this project. Do I just ensure that the the new carpark which serves the LEED project we are working on complies ?
