Why a person builds rectangular houses more often than others?

If you look closely, you can see that in nature most often there are spherical forms. They have rain drops, many berries and fruits, eggs, molecules, atoms, planets themselves … animal holes and anthills also have roundness in their foundation. Man as well as known, many inventions copy from nature. Why, in this case, he began to build buildings rectangular?

In fact, the first dwellings had oval forms. In some regions, they have been preserved now: for example, Yurts in Turkic and Mongolian nomads, tents – in eastern nomadic peoples. These dwellings have two common features. First, almost all of them are portable. Secondly, characteristic of deserted terrain – for example, where the wind does not have obstacles. And in such areas, it is especially important that the aerodynamics of spherical houses allows the winds to go about them without obstacles.

When people began to build rectangular houses, it’s not known exactly. One thing is clear: it happened when they switched to a settled lifestyle. But the reasons for this was somewhat.

The first is saving space. Rectangular houses easier to exercise and divide on the rooms. Consequently, they give the maximum area and economic benefits.

The second reason, oddly enough, is associated with air flows. From the point of view of aerodynamics of parallelepiped, that is, rectangles in the amount belong to poorly streamlined objects. When the air masses are squeezed by the building, areas can be created in which the air flow is spinning.

Why a person builds rectangular houses more often than others

But there is one trick. When streamling the house-parallelepiped, the wind leaves the corners, and on the side walls and the housing weakens. The flow of a flowing bowl house, on the contrary, accelerates on the walls. It turns out that inside such a dwelling is warm, but people who are on the street, after him, have to be disadvantaged due to the strong wind.

From here it becomes important, at home what form are located next door. Standing close to each other high-rise houses-parallelepipeds create these canyons in which the wind speed increases twice, which sometimes leads to sad consequences. An example of this is the catastrophe of 1965 at the British CHP in Ferrbridge. Hurricanes in these places are often, and CHP cooling towers were designed for severe gusts. However, three eight towers still collapsed, and the remaining five were partially destroyed. All because with ahead of the standing towers, the vortices were broken, which were broken by the towers below the flow, resulting in fluctuations, resulting in destruction.

The problem is that, looking at the layout of one building, it is difficult to predict how airflow incoming airflows will behave. For example, the height can redirect the wind so that the playground will constantly blow up, and in the parking, on the contrary, silence will stand. Therefore, it is necessary to blow the layout of the entire microdistrict in advance. True, in the existing construction norms of the mandatory requirement to do it. Here in some areas and hurricane vortices arise nowhere.
