I have a project building pursuing certification that is located on a campus.

Is there a flag exemption for government builds, as far as it pertains to light pollution? I havent been able to find a definitive answer.

Hi, we´re working on an commercial project. In a production hall of 270,000 ft. floor space and 39 ft.

Our project has a rear service entrance off a public alley. At this entrance the face of building is set 5 feet back from the property line and 7.5 feet back from the face of curb at the alley.

I have a couple projects where the property line falls a few feet from reaching the bordering roadway. In these cases, can the lighting boundary extend to the center of the road?

If we find the right kind of light fixture to be installed in the parking lot which can work well with an occupancy sensor, we will be able to reduce a lot of exterior light pollution for our proje
