Forgive me if this was covered elsewhere but I couldn't find it. We have a building with a 4th floor plaza that will have landscaping and landscape lighting that will be inside the lighting boundary. Does the landscape lighting on the 4th floor plaza need to meet uplight and/or the trespass requirements? Can I use the BUG method for compliance? If so, what do I consider as the "mounting height" - the actual height from the street to the fixture (so, 50' +) or the height from the 4th floor plaza? Thanks!

Any lighting outside of the building envelope needs to comply. Landscape lighting is listed as exempt as long as it is controlled appropriately. "lighting that is used solely for façade and landscape lighting in MLO lighting zones 3 and 4, and is automatically turned off from midnight until 6 a.m." If there are lights in the plaza that are not exempt, and are not shielded by solid building materials, I would use the mounting height from the street to the fixture. Can someone looking out of a neighboring building get glare from the light?
