How to calculate the usable area of a high-rise building?
In recent years, with the rapid development of the real estate market, the calculation of the usable area of high-rise residential buildings has become the focus of attention of home buyers. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the calculation method of high-rise residential area, and provide structured data for reference.
1. Definition of usable area
The usable area refers to the net area of a residence that can be actually used by residents, excluding public parts such as walls, columns, and pipe wells. The calculation of usable area is directly related to the actual living experience and cost-effectiveness of home buyers.
2. Calculation method of usable area of high-rise residential buildings
The calculation of usable area of high-rise residential buildings usually follows the following formula:
Used area = building area × housing acquisition rate
Among them, the housing acquisition rate refers to the ratio of the usable area to the construction area, which is usually provided by the developer. Housing availability rates vary for different building types and floors. The following is a reference table of housing availability rates for common high-rise residential buildings:
| Building type | Housing acquisition rate range |
|---|---|
| High-rise residential buildings (above 18 floors) | 72%-75% |
| Small high-rise residential buildings (7-17 floors) | 75%-78% |
| Multi-story residential buildings (below 6 floors) | 80%-85% |
3. Factors affecting the use area
1.Pool area: The common area of high-rise residences is usually larger, including public parts such as elevator shafts, stairwells, and corridors. The larger the shared area, the lower the housing acquisition rate.
2.building structure: The housing acquisition rates of frame structures and shear wall structures are different. Shear wall structures generally have lower housing availability rates than frame structures due to their thicker walls.
3.House design: Reasonable house design can reduce wasted area and improve usage efficiency. For example, square-shaped apartments are generally used more frequently than odd-shaped apartments.
