I have a adjustable fixture mounted on the ground to uplight the tree. The initial fixture lumen above 90 degrees from nadir is 0 which is full cut off fixture.

Can photometric plan be created with trees in it to avoid the leakage of light pollution? Thanks.

I do not understand if facade lighting is allowed and under what circumstances.

If project uses boundary lights (even near to boundary also), it is very difficult to comply the credit requirements. Is there any solution to this issue?

I'm working on a project that already submitted for Preliminary Design review.

I am working on a AAA Ballpark project. My understanding is that the lighting power density for the external floodlighting is required to comply with a figure of 2.15 W/m2 as it’s been classified

If I have parking lot lighting existing on a site that is near our project but outside the LEED boundary I assume that will not be required to be incldued in Light pollution calcs.

These questions are in regard to exterior lighting power calculation. I am fine with the general approach and calculation.

GBCI brought to my attention a correction that needed to be made to our FAQs.

Hi All, My project consists of a large parking lot where all interior parking spaces are located under solar canopies and perimeter parking spaces are uncovered.
