Space (BTS)

= area of city sidewalk /

(area of city block x Fave)

Where Fave = average

number of floors in one

block

A typical 10’ wide sidewalk wrapping around an average 600’ by 250’ city block is to be used as a modular unit for the financial district. With this model, we'd have the area of the sidewalks surrounding this particular block = 17,400 sq ft. Divide 17,400 by 150,000 (the area of the block) = 17,400/150,000 = 0.116 or 11% taken at ground level only. In a high-density district with at least 20-stories buildings (on the average) we will have 17,400/150,000x20 = 0.0058

(or 0.58 BTS)

Space (BTS) is directly proportional to the

combined length the city blocks (perimeter) in the city
