The building area is a real estate term and has a direct relationship with the calculation of the utility area and utility rate. Due to the differences between countries and regions, their definitions and measurement standards may not be the same. The building area is generally larger than the used area. The building 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. How is the construction area counted ? It is very important to understand how the building area is calculated.
Basic principles for calculating floor area
When calculating the floor area of ​​a house, if it is not met, the following principles apply.
The basic principles for determining the building area of ​​a house are:
Permanently fixed, the floor height of 2.20 meters (including 2.20 meters) above the house and the room connected to the indoor area calculated.
1. Calculating the total building area should be a house or site with a fully covered roof or a site with a roof, pillared or enclosed area.
2. Calculate half of the building area is generally not enclosed houses and parts (except for the bottom of the house).
3. The non-calculated building area is usually a house and site with a floor height of less than 2.20 meters; a decorative building; a site that is inaccessible to the interior; a publicly-owned building along a street-level street; and a building with no cover or cover that is socially common (except Take a balcony or a non-square outdoor staircase that is half the area outside.
How to calculate the construction area
I. Calculation of the total construction area
1. The house is calculated according to the external horizontal area of ​​the outer wall of the external structure. The building area of ​​the multi-storey building is calculated as the sum of the building area of ​​each floor.
2. The proportion of the indoor clear height above 2.00m (including 2.00m) in the pseudo-layer, pavilion (dark) building and slope structure roof is calculated according to the projected area.
3. The stairwells and elevator engine rooms with a floor height above 2.20m (including 2.20m) on the surface of the building are calculated based on the horizontal projection area of ​​the structure.
4. In the basement, mezzanine, basement, and independently built bike houses and garages, where the floor height is more than 2.20m (2.20m), the horizontal projection area of ​​the structure is calculated.
5, as the exterior wall of the house, such as glass curtain wall, calculated according to the horizontal projection area of ​​its periphery. Not as an exterior wall only for decoration, calculated according to the horizontal horizontal projection area of ​​the structure.
6. If there is a joint with expansion joints, if it is connected with the interior, the expansion joints shall be used to calculate the building area.
7. The outdoor stairs with roofs are calculated according to the horizontal projection area of ​​each floor.
8, pick the floor, closed balcony and gallery, according to the structure of the external horizontal projection area calculation.
9. For the pick-up layer in double-storey buildings, regardless of the height of the floor, the floor area is calculated by one floor. Stairwells are not identified as pick empty layers.
Second, do not calculate the scope of the building area
1. Install terraces, terraces, etc. formed by enclosing structures such as railings around the roof of a house, and do not calculate the floor area.
2. Expansion joints in the house that are not connected to the room do not calculate the building area.
3. The floor area of ​​houses with a net height below 2.00m (excluding 2.00m) in the pseudo-floor, pavilion (dark) building and bevel structure does not calculate the building area.
4, pick the floor, pick gallery, pick the bottom of the balcony projection part does not calculate the building area.
Summary: The relevant information on how to calculate the construction area is introduced here for everyone. I hope the efforts of Xiao Bian can help you. If there is anything that you do not understand, you can leave a message to Xiao Bian in the bottom, oh, we will do it as soon as possible. You answered that this website will provide you with more complete, more detailed and updated information information.

Railroad construction wooden sleeper characteristics
Wooden sleepers ,also called Pinus Sylvestris Wooden Tie,Rail Wood Ties,Rail Hardwood Sleepers,Rail Hardwood Ties, has good elasticity, light weight, easy fabrication, and other significant characteristics of insulation performance is good. Fasteners with wood blocking connection simple, laying and maintenance, transportation is convenient, wooden sleeper and have bigger friction coefficient between gravel ballast. Wooden sleeper toughening corrosion, can absorb more than other sleeper train weight and less prone to fracture. But its drawback is that use fixed number of year is shorter, consumption of large amount of wood. Wooden sleeper easy to corrupt, the reason from insect pests, the influence of the environment and climate, and the spike on the wood blocking hole by using long relaxation, wooden sleeper most commonly so only decades of life. To effectively extend the service life, sleepers generally must be used after filling the anti-corrosion. The sleepers, now use are embalmed, to prevent pests and to extend the use fixed number of year.
