Hi, How can in prove SSc8 for interior lighting, when my warehouse don't have windows? The building is just a warehouse. For exterior lighting it's ok, but for interior i don't know how to prove the requirements. Thanks a lot! SSc8 ...

A new building, for which LEED certification is sought, will be constructed on an elementary school campus that has multiple existing buildings. The LEED boundary is at the property line and includes all buildings on campus. Is it acceptable to include all new sight lighting but exclude all existing site lighting from the trespass calculations? SSc8 ...

We are looking into the potential of achieving LEED certification at a new School project. The school's property line is directly adjacent to a sidewalk/curb. The local city ordinances require that all pedestrian areas (i.e. the side walk) are lit to 1.5 footcandles. This value exceeds the SSc8 requirements for all zones (ours happens to be a LZ4). Are there any rulings that would allow for an exception to this requirement where public safety is concerned and a local ordinance requires lighting greater than LEED? Thanks so much in advance for any help. SSc8 ...

Our building is a warehouse with only a single string of clerestory windows at the peak of a gabled roof. All interior light fixtures are ceiling hung T-8s that are 10-12 feet below the bottom edge of the clerestory. I cannot determine how to execute this calculation, as the fixtures obviously have no direct line of site from the building. By changing the orientation of some of the calculations, this would work there were skylights, but in fact it a vertical clerestory window in the roof, not in the walls of the building. Could we show photos of the interior and sections of the building with as an alternative...

Does LEED-2009 EBOM eliminate any requirements for shielding exterior lighting fixtures at the property line? The only reference I see regarding this issue is listed on Page 72 of the Reference Guide, under "Light Pollution Reduction Strategies." Does this mean that as long as all the exterior light fixtures 50 watts and over are partially shielded so that they do not emit light into the night sky, then this requirement is met? SSc8 ...

of fixtures to glass. if I prepare theses diagrams for a 14 story building, how many do I need to show? there are LOTS of lighting configurations. SSc8 ...

The first floor of the building that we are working on is 10 feet narrower than the upper floors, in order to accomodate a walkway around a courtyard. The walkway is covered by the overhang from the second floor. We are trying to determine the line of sight for the interior windows on the first floor, but aren't sure how to calculate for this overhang. It definitely affects the line of sight for the fixtures. Any advice would be welcome. Thanks. SSc8 ...

Hi, We are working for G+2 Office Building to get LEED EB Rating. Further, we have completed Ext Lighting and started to work for Interior Lighting requirements. To complete this credit, we need clarifications from your end. How to determine which are the fixtures are having direct line of sight? and How to draw line of sight. Please Advise.. SSc8 ...

small parking lot north of the large existing lot to remain). We elected to include the existing parking lot within our project boundary- given that it would appear that we were overly segmenting the (2) locations if we separated them. Given that the existing parking lot to remain was to serve as the parking lot for the new building, our required number of preferred parking spaces was based on the existing lot... and the preferred spaces are shown in our LEED submittal to be located within this existing lot (close to the new building). We just received some mid-review comments asking for clarification...

to garner a lot of documentation for 1 point. Perhaps as it moves forward there can be an effort to minimize what needs to be provided or increase the number of points. Thank you, EQpc78 ...
