OUTER WINDOW PANEL AREA TO BE WASHED, might be a good assumption.
Building height, 300 m
Excluding the top and bottom, we have 4 surfaces,
Two, 30x300, and two 50x300.
We can assume each surface area contains 1/4 surface area with window.
Total area of windows to be washed = (1/4)(2x30x300+2x50x300) = 12000 m2
