When building a private house, there are many difficulties that often have to be solved even before the start of construction work. First you need to draw up a detailed plan for the future structure, indicating the exact dimensions of the walls of the house, rooms, sizes and location of windows and doors. After that, using this data, you can calculate the area of \u200b\u200bthe house along the walls. This is necessary to draw up a passport for the house and other regulatory documents when registering a building.
What is a living space
Before you calculate the area of the house on the walls, you need to clarify a few nuances. First, you need to know the definition of a residential building. Secondly, it is necessary to define what is meant by living quarters.
So, according to the law, a residential building is a separate building in which one family lives. It includes residential and other premises designed for comfortable living. All heated premises are considered residential. Unheated spaces such as balconies are not habitable.
When calculating the area of a residential building, the areas of all residential (living rooms, bedrooms, offices, and so on) and auxiliary (kitchen, toilet, bathroom, bathroom, boiler room, and so on) premises are taken into account.
How to calculate the area of the walls of a house
It is often necessary to know the area of the walls. This can be useful when drawing up a house plan, buying wall material (bricks, blocks, and so on), insulation, materials for interior and exterior wall decoration. Calculating the area of the walls of the house is very simple. To do this, you need to measure each of the walls and calculate their area, and then add the resulting values.
Let's consider a simple example of calculating the area of one room. Let it be rectangular. One wall will have a length of 6 meters, and the second - 5 meters, the height of the ceilings - 2.5 meters. Since the room is rectangular, it will have two pairs of identical walls. Therefore, we only need to calculate the areas of the two adjacent walls. We get the area of the first wall - 6 x 2.5=15 square meters, and the area of the second - 12.5 square meters. Since there are two identical walls, the area of the walls of the room is 2 x 15 + 2 x 12, 5=55 square meters.
Using these values, you can calculate the volume of the room. This is necessary when calculating ventilation and heating systems. The volume is calculated as follows: 5 x 6 x 2.5=75 cubic meters.
If you need to find out how much wall material you need to buy, then you need to subtract the area of \u200b\u200bdoors and windows from the area of \u200b\u200bthe walls. Let's assume room 5x 6 meters need to buy wallpaper. It has two windows of 1.5 sq. m and a door - 2 sq. m. Thus, for pasting the walls you need 55 - (1, 5 + 1, 5 + 2) u003d 50 square meters. meters of wallpaper.
Internal wall calculation
Since the area of a residential building is the sum of all areas of residential premises, it is necessary to calculate them without taking into account windows and doors. It should be noted that the area under the stairs up to a height of 160 cm is not taken into account. Also not included in the total area of the area of the parts of attic rooms with a ceiling height of less than 160 cm (if the angle of inclination of the ceiling is less than 45 °) and up to 190 cm (if the angle of inclination is more than 45 °). For the rest of the attic rooms, it is customary to apply a coefficient of 0.7. That is, the resulting area of \u200b\u200bthe room is multiplied by 0.7.
Now let's take a closer look at how the area of the house is calculated along the walls inside. The area of a rectangular room is the product of its width and length. With the area of \u200b\u200bthe walls of the room, which has the shape of a parallelepiped, we have already burst.
Let's move on to more complex forms. Calculate the area of the walls of the attic room. To do this, you must also calculate the area of \u200b\u200beach wall and add the resulting values. For simplicity, let's take the attic of a house with a symmetrical gable triangular roof. The areas of the walls along the slopes are calculated according to the norms of the height of the ceiling, as mentioned above. The areas of triangular walls are calculated as follows: the length of the wall along the floor is multiplied by the height of the room (in the ridge) and divided by two. Consider an example: the length of the walls along the ridge along the floor is 10 meters,the length along the slope is 5 meters, the width of the triangular walls is 8 meters, and the height along the ridge is 3 meters. Thus, the area of all walls is 124 square meters.
Calculation on external walls
If the calculation of the area of the house on the walls is done from the outside, then it is carried out as follows. The total area of the house is calculated. The area of \u200b\u200bthe walls is subtracted from it, and without taking into account door and window openings. Here all walls are taken into account - both load-bearing and partition walls. Parts of the premises (under the stairs or roof slope) and the area of non-residential premises are subtracted from the remaining area.
