Calculation formula for capacitated building area
1. Capacitated building area = the sum of all the building areas with calculated floor area ratio in the subdivision.
Calculated floor area = planning condition floor area = planning condition floor area X planning building land area Note: the planning building land area should be equal to or less than the total map land area, and the floor area ratio of the completed project can only be equal to or less than the planning condition floor area ratio 2. Total floor area = above ground floor area (floor area counted) + underground floor area (floor area not counted) 3. Above-ground floor area = floor area with plot ratio + aboveground floor area without plot ratio In general, the total floor area that can be sold refers to the aboveground floor area with plot ratio, and also includes part of the underground floor area that can be declared as property right (garage or parking space) 4.

The difference between floor area and measured area? Are both calculations the same?
(a) Floor area is a real estate term, which is directly related to the calculation of usable area and utilization rate.
The definition and measurement may not be the same depending on the country and region. Generally, floor area is larger than usable area.
Floor area is an important technical and economic indicator in the field of construction engineering, and is also one of the important indicators of national macro-control. Building area refers to the horizontal area of the structural periphery of the building above the foot of the outer wall, is to reflect the scale of construction of the house building in square meters of physical indicators.
The building area is also known as the construction area, which refers to the floor area of residential buildings above the foot of the outer wall peripheral horizontal surface measurement. It is an economic indicator that indicates the size of a building construction.
The floor area of each floor is calculated according to the horizontal cross-section of the perimeter of the external wall above the foot of the building. It includes three items, namely, the use of area, auxiliary area and structural area.
In Mainland China, the regulations related to floor area include the Rules for Calculation of Saleable Area and Apportionment of Common Floor Area of Commercial Properties and the current Rules for Calculation of Floor Area. In Hong Kong, China, the calculation of floor area and usable area is governed by the Code of Measuring Practice issued by the Hong Kong Institute of Surveyors.
In Taiwan, there are technical rules for buildings, and Chapter 9, Volume Control, regulates the volume ratio and floor area. In residential buildings, the scope and method of calculating floor area are: (1) single-story buildings, regardless of their height, are calculated as one story, and their floor area is calculated according to the horizontal area of the perimeter of the building above the footing of the external wall.
Single-story residential with part of the internal floor (such as attic) should also calculate the floor area. (2) Multi-storey or high-rise residential buildings, the building area is calculated according to the sum of the building area of each floor, the ground floor of the building according to the foot of the external wall of the peripheral horizontal area above the foot of the building, the second floor or two or more according to the peripheral horizontal area of the external wall.
(3) basement, semi-basement, etc. and the corresponding entrances and exits of the building area, according to its upper mouth of the outer wall (excluding light wells, moisture-proof layer and its protective wall) peripheral horizontal area. (4) with a deep foundation for underground overhead to be utilized, the height of more than 2.2 meters, according to half of the horizontal area of the periphery of the overhead floor calculation of the building area.
(5) through the building of the channel, building foyer, hall, regardless of height, are calculated according to the floor area. Hall corridor part of its horizontal projection area calculated according to the building area.
(6) elevator shafts, lift shafts, garbage paths, pipe shafts and attached chimneys, etc. are calculated according to the natural layer of the building construction area. (7) residential buildings within the technical layer (placing a variety of equipment and repair and maintenance), the height of more than 2.2 meters, according to the technical layer of the periphery of the horizontal area of the calculation of the building area.
(8) canopy structure of the outer edge of the line to the outer edge of the outer wall structure of the width of more than 2.10m, should be based on the canopy structure of half of the horizontal projected area of the area of the plate (with columns of the canopy and the calculation of the pillar-less canopy should be the same). (9) Stairwells, water tank rooms, elevator rooms, etc. that protrude from the enclosure of the house shall calculate the floor area according to the horizontal area of the enclosure periphery.
(10) overhead corridor between two buildings with a roof, according to the projected area of the corridor to calculate the floor area. The overhead corridor without a roof is calculated as half of the projected area of the building area.
(11) protruding wall of the doorway, overlooking the room, according to the perimeter of the enclosure horizontal area of the building area. (12) The balcony of the building are calculated according to 1/2 of its horizontal projected area.
The balcony, whether it is a pick balcony or a concave balcony, whether it is a closed balcony or a non-closed balcony, are calculated according to 1/2 of the horizontal area of the balcony of the balcony of the building area. (13) residential buildings without stairs, set up outdoor stairs (including evacuation ladder), its outdoor stairs by the horizontal projection of each floor area of the building; building with stairs, and set up outdoor stairs (including evacuation ladder), its outdoor stairs by half of the horizontal projection of each floor area of the building.
(14) Calculation of the scope of all building area 1, the house according to its external walls above the foot of the structure of the periphery of the horizontal area, multi-storey houses, building area according to the calculation of the sum of the building area of each layer. 2, false floor, attic (dark) and sloping structure of the roof of the net height of its indoor more than 2.00m (including 2.00m), according to its projected area.
3, the ceiling of the house on the height of 2.20m above (including 2.20m) stairwells, elevator rooms, according to the structure of the periphery of the horizontal projected area. 4, the ground floor, mezzanine, basement and the independent construction of the bicycle room, car garage, floor height of 2.20m or more (2.20m), according to the structure of the periphery of the horizontal projected area.
5, glass curtain wall as the external wall of the house, according to its peripheral horizontal projection area. Not as an external wall for decoration only, according to the structure of the periphery of the horizontal projected area.
6, there are expansion joints in the house, if it is connected to the interior, expansion joints calculated floor area. 7、Outdoor staircase with a roof, calculated according to the horizontal projected area of each floor.
8, picket floor, fully enclosed balconies and picket corridors, according to its structure of the periphery of the horizontal projected area. 9, duplex, leaping building in the picket part of the floor, regardless of the height of the floor, are calculated according to a floor of the building area.
The stairwell is not recognized as a picket. In addition, in the construction of residential buildings, the scope of non-calculated floor area are: (1) protruding wall components accessories, artistic decoration and hanging (wall) boards, such as: columns, stacks, feet and so on.
(2) maintenance, fire and other outdoor ladders, the width of 60 centimeters or less steel ladder. (3) Independent not attached to the external wall of the chimney, flue, cistern and other structures.
(4) There is no enclosure structure of the roof tank room. (5) Technical floors (equipment floors) with a floor height of 2.2 meters or less.
(6) Single-story residential separation of the operating room, control room, instrumentation room and other single-story rooms. (7) Floor height of less than 2.2 meters of deep foundation underground elevated floor, sloping building hanger space.
From the above, we can see that the calculation of residential floor area is more complex, not only more regulations, but also professional, technical is very strong. Consumers in the purchase of housing, if you do not understand, or the results of the calculation of doubt, you can consult a professional or ask a specialized measurement agency, in accordance with the above standards to re-measure the calculation.
1, the common domestic unit of floor area is square meters, the actual work of the calculation of the floor area of the house, mainly based on the provisions of the State promulgated the "Property Survey Code", the general calculation of the floor area of the house should have the basic conditions of the five: 1) should have a cover; 2) there should be an enclosure structure; 3) the knot.
What is capacitated floor area? The difference between and gross floor area
The difference between the use of floor area and gross floor area:
The capacitated floor area is the floor area of the part of the calculation of the floor area ratio.
Floor area = capacitated area + non-capacitated area.
Among them, the non-capacitated area is slightly different according to the provisions of the local planning section. Chongqing underground garage and garage-related equipment can not count the capacity. Can be used as a public **** green space overhead area can also not be counted and so on.
Definition of floor area:
It is directly related to the calculation of floor area and utilization rate. The definition and measurement standards may not be the same depending on the country and region. Building area is generally greater than the use of area. Building area is an important technical and economic indicators in the field of construction engineering, but also one of the important indicators of national macro-control. Building area refers to the horizontal area of the periphery of the structure above the foot of the building wall, is to reflect the scale of construction of the house building in square meters of physical indicators.
Definition of capacitated floor area:
It is equal to the area of the planned building land * calculated floor area ratio, the sum of all the floor area of the calculated floor area ratio in the small area! In general, the capacitated area is less than or equal to the building area, half basement counts half of the capacitated area, and the non-titled basement does not count the capacitated area.
What is the difference between capacitated area and non-capacitated area
Difference between capacitated area and non-capacitated area: 1, in the meaning of different: non-capacitated floor area (non-capacitated floor area), in short, is the calculation of the floor area, this part of the floor area is not taken into account.
Compensated floor area (calculated floor area) = the sum of all calculated floor area in the district. 2, in the category of different: the total floor area can be sold in general refers to the floor area of the floor area, including the part of the underground floor area can be declared property rights (garage or parking space).
The underground floor area is counted in the total floor area, but when calculating the floor area ratio, you do not need to calculate the underground floor area, which belongs to the non-counting area. 3, the two are for a different building area: calculation of floor area, in general: calculation of floor area = planning conditions floor area ratio X planning building land area; total floor area = above ground floor area + underground floor area.
Above ground floor area = floor area above ground + floor area above ground without floor area. Equipment piping mezzanine in the building.
