Dear all,

Please, could someone explain me in further detail how to proceed with the FAR calculation? 

I've to check, for a project I'm following, if we can follow the Path 3 - Zero lot Line.

From the LEED Guide I have found this:

"Calculate the average density of the area within a .-mile (400-meter) radius of the project building. If the density, expressed in terms of floor-area ratio (FAR) is less than 1.5, the project is ineligible for the zero lot line path" 

where ...

"floor-area ratio (FAR) is the density of nonresidential land use, exclusive of structured parking, measured as the total nonresidential building floor area divided by the total buildable land area available for nonresidential buildings."

QUESTION 1: Can I include in the nonresidential building floor area these: green parks, roads, public squares? Should I include something else?) as for example ... if I have a building with two floors entirely dedicated to business (offices) ... should I consider in the non residential area also the the square meters of each floor of this building?

also ....

QUESTION 2: what do we mean with: "the total buildable land area available for nonresidential buildings"  ? can I calculate it by subtracting from the total area included in the circumference with 400 meters radius all the areas dedicated to green parks , roads and public squares?

Thanks in advance for your help
