We are calculating the Exterior Lighting Power Density on a project that has building facade lighting on each facade.

The requirements state that for all zones: "Illuminance generated from a single luminaire placed at the intersection of a private vehicular driveway and public roadway accessing the site is allowed

It seems like most bollard lights emit light straight out to the sides at 180 or 360 deg spreads. Therefore allowing a lot of light to be emitted above 90 deg from nadir.

Has any one worked on/heard of a hotel project that was able to achieve this credit?

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

LEED interpretation 10236 (http://www.usgbc.org/leed-interpretations?keys=10236&=Search#) seems to indicate that the lighting boundary is a modification of the project boundary (e.g.

I think it would be good to show a sample submittal with a plan view of the site. Most people seem to think this credit is easy since the calculations they've seen were done wrong.

Our project is a major rehab of an existing classroom, class lab and academic department office building located on a college campus.

Does anyone have an experience with Ecotect in exterior lighting calculations?

It is necessary to check the level of lighting in facades that are not in the limit of the project boundary? (This facades are in plazas inside the project boundary, but not in the limit)
