How to calculate the public building area?

How to calculate the number of people using public buildings?

There is no definite proportion between the building area and the bathroom area, and it is also determined according to the number of people in the building.

JGJ67-2006 Code for Design of Office Buildings

Article 3.3.5 Toilets

A, toilet farthest working point should not be greater than 50 m .. Fourth, the number of sanitary ware shall meet the following requirements:

1? The men's toilet is equipped with a urinal for every 40 people and a urinal for every 30 people (urinal is equivalent to a urinal for every 0.60m length);

2? One toilet for every 20 people in the women's toilet;

3? There is a washbasin for every 40 people.

Note: ① If there are more than three toilets in each bathroom, one of them should be equipped with a sitting toilet.

(2) The floor with large conference room should increase the bathroom space accordingly.

(3) Special toilets can only be equipped with a sitting toilet, a washbasin and a mirror.

The office building can be converted according to the calculation of about 10 square meter per person.

Men's toilets in the station (crowded places): 100 for 25 people below 1 squatting position, 1 squatting position for every 50 people above/00. The number of urinals is the same as that of squatting posture.

Women's Toilet: People below 100 have 1~2 squatting positions according to 15, and people above 100 have 1 squatting positions for every 30 people.

The waiting room can consider 2 to 5 people per person.

Other architectural design codes can also be inferred. For example, the library is designed according to the architectural design code of the library.

Knowing the building area, how to calculate the indoor square?

Knowing only the building area, it is impossible to calculate the accurate indoor area, because we don't know how to distribute it and how many walls there are.

Calculation method of indoor space: length * width * height = room space.

Calculation method of indoor area: length * width = room area.

Example:

The house is 12m long, 4m wide and 3m high.

Room space: 12*4*3= 144 cubic meters.

Room area: 12*4=48 square meters.

After the renovation of the new house, there is indoor air pollution, including formaldehyde and other gases harmful to the human body. It is recommended to open the window for 2-4 weeks, and put some flowers indoors, such as chlorophytum, Cynanchum multiflorum, ivy, aloe, agave, hibiscus, chrysanthemum, radish, begonia, Commelina, etc. Chlorophytum can absorb more than 80% of indoor harmful gases, and its ability to absorb formaldehyde is super strong.

How to calculate the construction area of public space?

Calculate the total area according to the peripheral size of the external wall.

How to share the public building area?

The first floor residential area can be divided into pool area+interior construction area+balcony area.

Indoor construction area S 1,

This balcony covers an area of S2-the whole area.

The floor share area S3,

Construction area of each household = S 1+S2/2- interior construction area+half of balcony area.

Allocation coefficient = construction area of each household/total construction area of each household on this floor-this ratio is the allocation coefficient of each household.

Household allocation area = allocation area * household allocation coefficient

Xing Tao building area = s 1+S3- Xing Tao building area+shared building area. That is, the current area is limited to 90 square meters.

(The area line of the public * * * part can be included in the inner wall and the outer wall line, and the area of the public * * * part connected with the outdoor space can be included in the outer wall line; The space and area in the set are calculated to the center line of the wall)

How to calculate the required toilet mask 5 points according to the public building area?

There are rules. There is no definite proportion between the building area and the bathroom area, and it is also determined according to the number of people in the building.

How to calculate the housing area?

Generally, it is calculated by the area of real estate license.

The carpet area of your own house (that is, the place where carpets and floor tiles can be pasted), plus the area occupied by building components such as columns and walls, plus the public * * * area shared by each household such as corridors, elevators and equipment floors, is the construction area. Moreover, according to different huxing, the calculation of balcony area is different, and some houses have only half the area. And the usable area is almost the carpet area (that is, the area where you can generate energy yourself).

The building area on the property certificate may be slightly different from that on the purchase contract, but it will not be too big, which is normal. When you get the property right certificate, you can look at the page where the surveying and mapping results are posted. There is a pool coefficient, common banlou 1.33 and tall tower 1.44. This pool coefficient is the ratio of the building area and the usable area (note that this usable area is not the usable area of the suite mentioned in your question, but the carpet area plus the area occupied by the building components) that falls on the real estate license.

How to calculate the building area and actual use area of the house?

The construction area and actual use area of the house are measured by professional companies and teams.

Here is the concept of a pool.

The apportionable public building area in the Code for Property Survey, that is, the pool area, is: pool.

1. Lobby, foyer, corridor, aisle, elevator (building) hall, stairwell, elevator shaft, elevator machine room, garbage chute, pipe shaft, water pump room, fire escape, transformer (distribution) room, guard room on duty, etc. , as well as public * * * rooms and property management rooms serving the whole building, have the following functions.

2. The partition walls and external walls (including gables) between each set and the public building space are half of the projected area of the wall surface on the water surface.

The public building space that should not be included is:

1. Warehouse, motor vehicle garage, non-motor vehicle garage, driveway, etc. As the basement of civil air defense engineering and independent use space with independent use function;

2. Houses sold by self-operated and self-used units;

3. The guard room and management (including property management) room serve multiple houses.

* * * The assessed construction area is the construction area of the whole building, after deducting the sum of all sets of construction areas of the whole building, the construction area after the basement, carport, shared garage, management room and civil air defense works.

Fold and edit the calculation of pool area in this paragraph.

Calculation of pool area

Pool area calculation construction area = interior construction area+pool area

Pool area = pool coefficient × interior construction area

Allocation coefficient = total allocation area/(interior construction area × total number of units)

Interior construction area = interior usable area+wall area

Factors affecting pool area

1. One staircase, one household, two households and three households in the same building are all different. Classic property market is different from plate property market.

As you said, the bigger the house, the more indoor area, and the smaller the house, the less.

The only public facilities are stairs, which are different from elevators. The more public facilities and corridors, the bigger the swimming pool.

4. Building scale The higher the height of stairs, the larger the pool.

Share ratio of ordinary houses: multi-storey 8%- 15% small high-rise 10%-20% high-rise 15%-30%.

Fold and edit how to form the pool area of this paragraph.

The so-called shared area, that is, shared construction area, refers to the public construction area that each set (unit) of commercial housing should share according to law. In the actual process of buying a house, most buyers are accustomed to buying a house according to the construction area, while ignoring the concern about the pool area.

So what part is the pool area made up of? The reporter learned that at present, there is no law to limit the pool area in China, only the administrative regulations of the Ministry of Construction and the principled provisions made by local department documents. At present, this policy is mainly implemented according to the national standard of People's Republic of China (PRC), Code for Property Survey, which came into effect on August 1 2000.

According to the Code for Property Survey, the shared public building area is 1. Lobby, public hall, corridor, aisle, elevator hall, stairwell, elevator shaft, elevator machine room, garbage chute, pipe shaft, water pump room, fire escape, power supply and distribution room, and the guard on duty serve the whole building.

Public building spaces that should not be included include warehouses, motor vehicle garages, non-motor vehicle garages, driveways, etc. As the basement of civil air defense project, it has independent use space with independent use function. Houses sold by self-occupied units serve multiple houses and serve management (including property management).

How is the construction area of shops calculated?

General 10%-20%. In fact, my shop pool accounts for 40%.

1, about "area"

"Building area" includes shared area and paid-in building area. That is, the construction area includes the living area, wall column area, staircase and walkway area and other common areas of the house.

"Actual construction area" is commonly known as "usable area". It is the balance of "building area" after deducting the apportioned area.

The area that the owner can directly use is called "usable area", commonly known as "floor tile area". It is a concept of content space after deducting the space occupied by columns, walls and other buildings on the basis of practical area.

2. The pool area is chaotic.

The shared area on the first floor mainly includes stairs, elevators, aisles and lobby on the first floor. Some real estate pools also include water rooms, electricity rooms, security kiosks and other supporting facilities.

At the same nominal price, the latter is much higher than the former. At present, there is no accurate legal norm to deal with the pool area, so buyers should not be underestimated.

How to calculate the building area of the office building?

The construction area includes the usable area of the house, the area of wall columns, the area of stairs and walkways, and other common areas. The usable area of the office building refers to the sum of the net area of each floor of the office building directly used by residents. Calculating the usable floor area of an office building can directly reflect the usage of the office building, but the usable floor area is generally not used to calculate the price in office sales. There are some special regulations when calculating the usable area: the indoor stairs of duplex office buildings are included in the usable area according to the total area of natural floors; Chimneys, ventilation pipes and pipe wells that are not included in the structural area are included in the use area; Interior wall decoration thickness is included in the usable area. Office rent is calculated according to the usable area. The public area of an office building refers to the sum of the areas occupied by public corridors, stairs, elevators and water tanks. In the office building, it is convenient for residents to go in and out, normal communication and guarantee life. The construction area calculated by developers when selling commercial housing has the problem of sharing public area. The living area of an office building refers to the sum of the net living area of rooms directly used by residents on all floors of the office building. The so-called net area is the horizontal area (that is, the structural area) occupied by building components such as walls and columns. Area index generally used to measure living standards. The shared public building area of office buildings and commercial houses is mainly composed of two parts: 1. Construction area of elevator shaft, stairwell, garbage chute, power distribution room, equipment room, public hall, aisle, etc. Functionally serving the whole building, managing the construction area of the building; 2. The distance between each unit and the horizontal projection area of public building space and external walls (including gables) is 50%. The completed area of office building refers to the sum of the completed building area. Housing construction should be completed according to the design requirements and accepted. Auxiliary area of office building refers to the net indoor area of each floor of office building that is not directly used for home life. Including aisles, kitchens, bathrooms, bathrooms, living rooms, storage rooms, etc. Office building * * * Housing construction area refers to the construction area shared by or used by all property owners. * * * The ratio of the self-owned building area of the whole building to the sum of the building areas of all suites in the whole building is the sharing coefficient of the self-owned building area of * * *. The public building area allocation coefficient divides the public building area of the whole building by the sum of the building areas of the suites in the whole building to get the public building area allocation coefficient of the building. That is, the allocation coefficient of public building area = sum of public building area/interior building area. Sales area Sales area refers to the commercial housing sold in units or units, and its sales area is the sum of the interior or interior area purchased by property buyers (hereinafter referred to as interior area) and the apportioned interior area. Utilization rate, utilization rate is the ratio of indoor building area to office area, which is greater than utilization rate. That is, utility rate = interior construction area/interior construction area+shared interior construction area. Room rate (for example) refers to the ratio of the building area in the suite to the building area of the suite (unit). Interior construction area = interior usable area+interior wall area+balcony construction area. Building area of apartment (unit) = interior building area+shared public building area. The interior construction area of the house is115m2, and the sharing rate is 12%. What is the housing acquisition rate? The plot ratio of about 88% (for example) is the ratio of the total construction area to the construction land area. For example, on the land of 654.38 million square meters, the total construction area is 4,000 square meters, and its plot ratio is 0.4. The higher the plot ratio, the greater the building area and the lower the unit land cost. At the same time, it also means that the per capita green area decreases and the quality of living environment declines. 1. From the home point of view, the lower the floor area ratio, the better and more comfortable the living environment. 2. From an economic point of view, the higher the plot ratio, the greater the land utilization rate, the higher the land price, and the higher the income of cities and land users.
