We have a high-rise building for which we are pursing LEED EBOM v4.1. Since that building only has an LED vertical columns lighting on the facade. Other than this no exterior fixtures are used? To claim this credit point, do we need to consider that facade lighting ? if yes, in this case its LED what should we provide them with? if this can be exempted, then can we claim the point on the basis of no exterior lighting within the LEED boundary?

2. The exception is based on how bright the light source is. LED light sources are not technically lamps and are typically measured as a whole fixture. Which helps a bit since luminaire lumens are always less than lamp lumens.
You'll need the IES file from the manufacturer. The IES file or cutsheet will give you the Total Luminaire Lumens. If it is less than 2,500 lumens from the credit language then it is exempt. Provide this IES file or cutsheet as your documentation it is exempt.
3. If this is exempted you can claim the credit. The form gets a little weird when there are zero lights. You may need to input 0 or 1 lumen.
