First, the national unified building area calculation rules (national commissions in 1982 enacted regulatory documents) as its main calculation rules are as follows: the scope of the calculated area
1. single buildings regardless of how great are a tier computing, and its building area is feet by exterior Le more peripheral levels area calculation. Single-storey buildings such as those with part of the floor, a building area should also be calculated.
2. level with cross-storey, need to calculate area respectively, when the high cross-boundary cross, its building area is feet above ends by Le Gables on the external surface of the horizontal length between multiplied by more than wall surface-foot-high cross-column horizontal width outside line; when cross-high cross as its building area is feet above ends by Le Gables on the external surface of the horizontal length of the column outside the line multiplied by the horizontal width calculation.
3. the multi-storey buildings of the area by all levels of the sum of the area, its underlying the exterior Le foot above the perimeter level area; on the second floor and second floor above the level of the exterior surface area calculation.
4. basement, semi basement, underground workshops, warehouses, shops, underground headquarters, and the entrance of the building area at the upper estuary wall (not including the lighting well, moisture-proof coating and protection walls) peripheral level area calculation.
5. the Foundation do with deep underground and overhead layer, layer high above, aerial 2.2m layer perimeter level area of half the calculation area.
6. sloping architecture using lifting toe overhead layers, and layer high over 2.2m, according to the wall perimeter level area of building area.
7. through the building of the channel, building hallway, Hall irrespective of its height, the calculation by a layer of building area. Hallway, Hall corridors parts according to its horizontal projection area of building area.
8. library of books on the Bookshelf tier computing area.
9. the elevator shaft, extracts of wells, well-rubbish road, pipes, etc. are calculated according to the natural layer buildings construction area.
10. stage lighting control room press surface horizontal envelope area multiplied by the number of actual layer construction area. Building technology layers, layer high above the, should calculate 2.2m construction area.
11. There is a column by column foreign standard awning space area, independent of the level of terminals by top cover one half of the projection area calculation area.
12. There is a column in the carport, goods shed platform level as per column in the external area calculation area; single-row columns, independent columns shed, booths, platform, and so on-top of horizontal projection area of half the calculation area.
13. highlight the roof with the stairway enclosure, water tanks, elevator room as per envelope surface area calculation area level.
14. a prominent wall door bucket level according to the wall surface area calculation area.
15. enclosed balcony, pick Gallery, the horizontal projection area of building area. Au patio, balcony press its horizontal projection area of half the calculation area.
16. building the top cover and outside the wall of the corridor, eaves outside the line of the column level area of building area.
17. railway corridor, eaves according to its projection area of half of the calculation area.
18. the two buildings there top aerial corridor, the press gallery of projected area calculation area. Do not cover overhead Gallery according to its projection area of half the calculation area.
19. outdoor stairs as the main channel and for evacuation by each layer horizontal projection area calculation area; the building has stairs outdoor stairs at their level in the projected area of half the calculation area.
20. across other buildings, structures of elevated storey, according to its horizontal projection area of building area, multi-tier drivers multi-tier computing.
