SSc8 includes a limitation in terms of the total initial designed fixture lumens emitted at an angle of 90 degrees or higher from nadir (for example, 2% for LZ2).

I have been working on a 1000-person lodge which is shooting for LEED Silver.

I'm working on a project currently that requires exterior security cameras.

Hi, I am working on a building that has commercial activities on the street level floor and offices on the rest of the floors, the project is places in Lz4..

Can a project boundary extend into a lake? I have a Department of Natural Resources building located on a lakefront. They have a public boat landing on site.

I believe there is an error in the Sample LPD Calculation file that has been provided. Or, my understanding how to correctly calculate the LPD is wrong.

This may stretch a bit outside the LEEDuser realm, but...... I received a comment on a past project, where the reviewer wanted verification that the project was actually a LZ3 as defined by IESNA

Hi, gang, One of our lighting designers is very frustrated with the LEED requirements for light trespass at the boundary, specifically where the driveway goes from the public road onto our site.

Hello All, Are exterior uplights exempt from the 90 degrees above nadir categorisation if they are under cover of a shading structure, such as a canvas sail or cabana?

1. One of our project have around 1000 m2 landscaping area. In which they are using 20 numbers of 10W bollard external lighting in only 400m2 area.
