What is the formula for calculating the area of the building fa ade?

The area of the building exterior wall is calculated as:

Method 1: Calculate the extent of the floor area.

1. Single-storey buildings are calculated as one floor regardless of their height, and their construction area is calculated according to the outer horizontal area above the foot of the outer wall of the building. If a single-storey building has some floors, the gross floor area should also be calculated.

2. If the construction area of a single-storey building with high and low spans needs to be calculated separately, when the high span is a side span, the construction area shall be calculated according to the horizontal length between the outer surfaces of the gables at both ends above the leg multiplied by the horizontal width of the outer wall surface above the leg to the outer edge line of the middle column of the high span; When the high span is a middle span, its construction area is calculated by multiplying the horizontal length between the outer surfaces of the gables at the two ends above the leg by the horizontal width of the outer edge of the middle column.

3. The construction area of a multi-storey building shall be calculated according to the sum of the floor area of each floor, and the ground floor shall be above the outer wall of the building.

Method 2 is multiplied by multiple after the wall area (length and width) is calculated, method 3 is calculated when calculating the wall area, doors and windows and heating covers, etc., method 4 is calculated by multiple of the ground area.

Method 5 is a few years ago when the Beijing home decoration wall was popular to paste wallpaper, the construction party in order to facilitate the calculation of the method, in fact, the calculation is not the wall area, has rarely been used by the decoration company.

Exterior wall area = (length of building + width of building) * height of building - area of door and window openings + area of side of door and window openings.

I don't know what you're used for.

But when we paint the exterior walls.

Commonly used front and rear wall area (total length of the house * height of the house * 2) - total area of windows * (1 2) + gable (wall without windows) area. Compute.

The fluctuation range of floor height and body shape coefficient of residential buildings is very small, the floor height is generally meters, and the system coefficient is generally about about . Under normal circumstances, the building with a high floor height is generally a small house, and the shape coefficient will be relatively large, and the residential unit with a high floor height is large, and the shape coefficient is small if the building is relatively regular, so the value of the building floor height multiplied by the body shape coefficient is generally around the right.

Applying the derived formula, we get:

The roof area of a residential building is equivalent to the standard floor area, and the standard floor area of a general residential building is about 250 400 per unit, and for the construction area, the more floors there are, the more negligible the value of the roof area. For the above formula, the roof area can be ignored and the coefficient can be taken to the lower limit, so that the following is obtained:

That is, the area of the exterior wall of a residential building is approximately equal to 90% of the floor area. Of course, it is possible for the building façade area to be 80 100% of the floor area due to architectural differences, and in general, the building façade area is close to the floor area.

Estimation of the area of the exterior wall of an office building.

The fluctuation of floor height and body shape coefficient in office buildings is slightly larger than that of residential buildings, and there is no correlation between the two, so the value range of floor height multiplied by body shape coefficient is also larger. Under normal circumstances, the floor height of office buildings is generally meters, and the system coefficient is generally about one. Therefore, the value of the building floor height multiplied by the shape coefficient is generally around the limit.

The roof area of office buildings is also relatively large, generally accounting for 5% to 10% of the floor area, of course, the higher the building height, the more negligible the value of the roof area.

Typical floor area, shape factor, roof area reference model.

Based on the above analysis and applying the derived formula, the following is obtained:

That is, the area of the exterior wall of the office building is about 30% 70% of the construction area. From the height range of 30 200 meters, the higher the building height, the more regular and square the body shape, the lower the coefficient, and the common office buildings within 100 meters can take the left and right coefficients.

Calculation of the exterior wall area of the building: 1. If the exterior wall bricks are all exterior walls, the approximate ratio to the construction area is: the construction area multiplied by the exterior wall with a less complex structure is usually multiplied by the construction area.

3. The exterior wall is usually multiplied by the floor area. 4. Exterior wall plastering (or facing bricks) is usually the construction area multiplied by about that. 5. If the exterior wall tiles are all exterior walls, the approximate proportion to the construction area is:

The floor area is multiplied by (, is a small high-rise without a light well.

Exterior wall design: 1. Exterior wall energy saving: 1. As the largest envelope surface of the building, the exterior wall has great potential in the building energy-saving design.

2. For example, in the design of the passive solar room, the exterior wall is designed as a heat collector (or heat dissipator), combined with the utilization of solar energy, and the air replacement layer is set on the outer and outer walls to achieve the comprehensive thermal insulation and thermal insulation and energy-saving effects of the wall. 3. In order to implement the national energy-saving policy and improve the situation of high heating energy consumption and poor thermal efficiency of residential buildings in severe cold and cold areas, energy consumption must be saved through building design and construction measures. As an envelope structure, the energy-saving design of the wall is of great significance to the low energy consumption of the whole building, and the state has also introduced a series of technical measures related to wall energy conservation to standardize this field.

2. Exterior wall sound insulation: 1. In order to ensure a good working and living environment indoors. The exterior wall must have sufficient sound insulation capacity to avoid sound absorption interference to the indoor environment.

2. Therefore, in the structural design of the wall, different materials and technical means should be used to make the buildings of different properties meet the requirements of building sound insulation standards. The sound insulation of the exterior wall mainly refers to the isolation of gas sound transmission and solid sound transmission. 3. The exterior wall is mainly to isolate the noise directly transmitted by the air.

Generally, the following measures are taken: strengthen the filling treatment of wall joints; increase the thickness of the wall and the compactness of the wall; and sandwich walls with air interlayers or porous materials, and the use of vertical greening to reduce noise.

Questions. There are light wells on the exterior walls, and there are multiple lines on each floor, all according to the actual area, and the roof has a large frame.

Regardless of area. Search for yourself on the Internet, the 2005 version of the area calculation rules.

Exterior wall area = (length of building + width of building) * height of building - area of door and window openings + area of side of door and window openings.

Defined by the judgment method, if A-B is a wall, if the A-B wall line can cut the relevant envelope structure, it is the internal wall, and vice versa, it is the external wall.

The formula for calculating the floor area is length x width x number of floors. The construction area refers to the horizontal plane area of the building, the sum of the area of each floor of the building calculated in units of one square meter, and the construction area includes the usable area, auxiliary area and structural area.

When there is a local floor in the building, for the second floor and above of the partial floor, the enclosure structure should be calculated according to the horizontal area of the periphery of the enclosure structure, and the horizontal area of the structural floor without the enclosure structure should be calculated according to the horizontal area of the structural bottom plate, and the structure floor height is m and above, the full area should be calculated, and the structure floor height is below m, the area of 1 2 should be calculated.

Single-storey buildings, regardless of height, are calculated as one floor, and the construction area is calculated according to the outer horizontal area above the foot of the external wall of the building.

1. If the exterior wall tiles are all exterior walls, the approximate ratio to the construction area is: the construction area multiplied.

2. Exterior walls with less complex structures are usually multiplied by the floor area.

3. The exterior wall is usually multiplied by the floor area.

4. Exterior wall plastering (or facing bricks) is usually the construction area multiplied by about that.

5. If the exterior wall bricks are all exterior walls, the approximate ratio to the construction area is: the construction area multiplied by (, which is a small high-rise without a lighting well.

The floor area is calculated according to the contour line of the exterior wall.

The construction area is also known as the construction area, which refers to the sum of the plane area of each floor measured by the outer horizontal plane above the foot of the external wall of the residential building.

Tooth decay can understand how to calculate the drawings, the individual calculation is different, but also according to the complexity of the exterior wall lines, generally simple is to calculate a large area in the deduction of air conditioning holes and door and window openings.

Generally, the exterior wall area is good, the exterior wall area and construction area should be 1:1, if the exterior wall area is poor, there are many door and window openings, and the exterior wall area is compared to the construction area, :1, but it is the actual area, length x width x height, and then deduct the area of the door and window openings.

1. The area of exterior wall decoration plastering, calculated according to the vertical projection area, should be deducted from the door and window openings, empty circles, waist lines, eaves, door and window covers, sunshades and the area occupied by the above holes, without deducting the area of the inner holes, the side wall attached to the wall column should be calculated, and incorporated into the corresponding wall plastering engineering quantity.

The area of door and window openings and side walls of the holes has been comprehensively considered in the project and is not calculated separately. If there is a thermal insulation layer on the outside of the outer wall, the vertical projection area of the outer edge of the thermal insulation layer shall be calculated in square meters.

2. The cement blackboard is calculated according to the outer area of the frame, and the blackboard frame and chalk groove plastering have been taken into account in the project and are not calculated.

In fact, there are generally two ways to calculate the area of the coating industry:

1. Calculate according to the facts, that is, the actual receipt, how much is calculated, subject to field measurement, and according to the implementation of the engineering quantity calculation rules, do not deduct the hole area below the square meter and do not increase the corner area of the window to achieve balance, this method is suitable for relatively standardized large and medium-sized formal engineering accounting;

2. Budget estimation method, wall and top area to the estimated budget coefficient as the reference value, the general coefficient in the line is 3 times, that is, according to the actual use of the area multiplied by 3 to obtain the total number (ignoring the increase and deduction of the area, more than 3 meters of floor height appropriate increase coefficient points), as you said 5 meters multiplied by 4 meters = 20 actual use of square meters and then multiplied by 3 (budget estimate coefficient) = 60 square meters of wall, the total area of the roof, this calculation method is the fastest, but also the result of comprehensive acquisition, more suitable for the civil informal valuation!
