interior buffer

conceptually this doesn't seem hard, but i can't figure out how to do the following:

 

i have 700 building footprints.  i am trying to show what it would look like if 35% (or $40% or 70% etc) of each building footprint had a green roof on it.  i did some research and tried using a parcel fabric.  that didn't work because while it did allow me to split the buildings into equal parts, i couldn't specify a percentage.  also, you had to split each footprint individually - i am looking for something that will allow me to do it all at once.  next i though about using an interior buffer.  if i can calculate the distance of a buffer to "eliminate" 65% of a building footprint (so that 35% remains) that could work.  however, i am not a math/geometry wiz - how would one go about calculating the distance of a buffer as i described above?  baring that, is there another approach i am missing?
