The following areas are to be excluded from gross floor area for the purpose of computing floor area ratio: (FAR)
• Basement, underground parking, and attic spaces.
• Porches, balconies, patios, breezeways, and decks (as well as overhangs, eaves, cantilevers, awnings and similar
features) with a "solid" cover but not enclosed by "solid" walls on more than two sides.
• gardens which do not have a "solid" cover.
• Parking structures and garages which are incidental to a primary use on the same site in multi-family, commercial,
office, industrial and public/semi-public uses.
• Air spaces within buildings such as vaulted ceilings or the air space above an atrium in an office or museum building.
More specifically, the floor area shall be counted at the actual floor area only and not in the air spaces above.

How do you calculate gross floor area?
total floor area exclude basement (for parking) and roof top area.
How do you calculate floor area ratio?
FAR=Total floor area of building / Total lot area
Calculate floor perimeter area ratio?
the p/a ratio is the sum of the perimeter divided by the area therefore if perimeter is 20m and the area 25m2 the sum is 20/25=0.8
Is the floor area the same as the square footage?
If the square footage refers to floor area, yes.
How do you calculate forging reduction ratio?
reduction ratio= initial cross sectional area/final cross sectional area
