I have a dumb question - when they ask for Initial fixture lumens per lumenaire, do they want fixture output lumens or the lamp lumens? Big difference in the percentage calc.

We are trying to determine how best to treat a pathway that extends beyond our LEED project boundary.

We are going to provide the LED strip along the vertical line of the building facade. If we assume that the 50% of their lumen is above 90 degree from nadir then our bldg.

I have a project building located on a campus site, which consists 3 buildings from the same owner, but only one of the buildings is seeking for LEED certification.

http://www.leeduser.com/comment/redirect/24547 Per GBCI, the Leed Reviewers are allowed to request a vertical calc grid if they are concerned about an area of the site.

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

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

project is along an arterial road with lots of city lights.

We are doing external lighting simulation for factory building. We are using 250W street light fitting (10nos) and there is no other type of lights.

Can actual lighting level measurements be used as for compliance for this credit?
