We are working on a rural site which will be classified as LZ1, so will not be allowed any light to be emitted above 90 degrees from nadir. The way the SS Credit 8 is written within this version of LEED, it requires a “worst case” scenario of any adjustable exterior luminaires regarding the position of the light. (In other words any adjustable luminaires need to be directed to the sky, which would disqualify us from earning the credit.) The project's current design calls for tree mounted luminaires, which would be mounted to tree strap, as to not harm the tree.. The luminaire would be mounted in a fixed mounting position, and will not be adjustable to the owner.

Our specific question is whether or not LEED/GBCI will interpret these tree mounted luminaires to be adjustable, or have any potential uplight contribution in our lighting calculations. Please advise.
