Introduction to area ratio calculator
Ratio of areas of two surfaces is called the area ratio. For example, a rectangle is constructed inside a circle such that the circle lies on the four vertices of the rectangle. The ratio of the area of the circle to the area of the rectangle is known as the area ratio.
This is especially useful in calculating the Floor Area Ratio (FAR). The floor area ratio is the ratio of the sum of the area of all the floors in a building to the area of the plot on which the building is constructed. The floor area ratio is used to limit the number of floors that a building can have.
Calculating Floor Area Ratio (far)
For example, a building is built on a plot of area 12000 square feet, and there are two floors in it. The area of each floor is 10000 square feet. Then the floor area ratio is given by
Floor area ratio = Sum of areas of all floors/area of plot
`= (2 * 10000)/12000`
`= 20000/12000`
`= 1.66`
The floor area ratio is known by different names in different countries. In Australia, it is known as “Floor Space Ratio (FSP)” and “Plot ratio”; in India is it known as “Floor Space Index (FSI)”; in UK, it is known as “Plot ratio” or “Site ratio”.
The floor area ratio is used widely in zoning and city planning. It is used to limit the number of floors. An architect has to adhere by a particular floor area ratio for a particular site and construct a building in accordance to it.
General real estate appraiser at Analytic Real Estate Services, Edward Ptacek noted in 2009 that the maximum allowable floor area ratio of a particular place affects the value of the land. The greater the floor area ratio, the more is the value of a particular land.
The concept of floor area ratio has been widely used in Japan since the 1970's to build the residential colonies. However, it is arguable whether this has proved beneficial or not. Some say it is beneficial, and some say that it is not so. I am planning to write more post on How to do Math Problems, factoring polynomials word problems. Keep checking my blog.
Use of Floor Area Ratio in Zoning
Zoning is the method of dividing land into various parts each part intended for a particular usage like residential, commercial, industrial, recreational. The local governments of each city make a zoning map which shows the exact division of land use in that city.
The main factors that affect the zoning of a city is the population, land-usage, existing settlements, etc. By using the concept of floor area ratio in zoning, a city can be efficiently zoned in accordance with the above mentioned factors.
Different values for the floor area ratio are predetermined for different parts of land in the city. This helps to limit the amount of construction on a particular piece of land. For example, the floor area ratio of a region in the vicinity of an airport has to be less so as to inhibit the height of buildings in that area.
An architect can make buildings of different dimensions to adhere by the limit of the floor area ratio. For example, a building built on a large plot having only two floors and a building built on a smaller plot having three or four floors will have the same floor area ratio. Thus, an architect can choose the buildings' dimensions accordingly.
