Wall To Floor Ratio Efficiency

0 52 it is worth noting that a circular plan is the most efficient shape in terms of wall to floor ratio as indicated below.

Wall to floor ratio efficiency.

As a formula far gross floor area area of the plot. The floor area ratio far also known as the plot ratio is a measure of the total permitted floor area of a building in relation to the total area of the lot or plot on which the building stands. A two story building on the same lot where each floor was 500 square feet. The floor area ratio of a 1 000 square foot building with one story situated on a 4 000 square foot lot would be 0 25x.

0 35 however in very few cases is this the most economical plan shape of a building as the cost of constructing a circular as. A measure of the plan efficiency of a building computed by dividing the face area of its external surfaces excluding gable walls parapet walls and walls below the lowest finished floor level by the fully enclosed covered area feca and expressing the results as a ratio. The terms can also refer to limits imposed on such a ratio through zoning. Gross floor area of all floors of the building area of the building lot far a higher ratio indicates a higher density environment.

Building a area of enclosing walls total floor area 50m x 3m 100m 1 50. Building b area of enclosing walls total floor area 40m x 3m 100m 1 20. Floor area ratio far is the ratio of a building s total floor area gross floor area to the size of the piece of land upon which it is built.
