If I understand the LEED requirements for exterior lighting, we will be following the BUG guidelines for all lighting that will remain on from sunset to sunrise. For the building and landscape uplighting a astronomic time clock will turn these fixtures off at midnight, which the LEED guidelines state is acceptable. Am I missing something?

If we are following the BUG option and we have a fixture that will be completely shielded, but doesn’t have a BUG rating, how do we document that for LEED? Use software that will calculate the BUG rating using the IES file for the luminaire?
