Residential window opening method: Sanyang Kaitai and no worries

Daylighting refers to the situation in which the house receives sunlight. It is best to use solar energy to directly illuminate, or it is the bright refracted light, so windows become more and more important. In apartment-style houses, windows have become the main air outlet, so most of them are double-seaters.

Window size

According to the three functions of windows, namely sunlight, ventilation and long-distance viewing, the windows are required to be opened as large as possible. The general standard is: the ratio of the area of ​​the window to the area of ​​the home floor is 1:8 or 1:7. The size of the window is also related to the depth of the home: the depth of a room with windows on one side for daylighting should not be greater than 2 times the height of the window; for a room with windows on both sides for daylighting, the depth should not be greater than 4 times the height of the window. The general rule is two windows for rooms below 15 square meters and three windows for rooms above 15 square meters.

Everything grows by the sun. The ancients attached great importance to the sunshine in the house. There is such a contrasting saying: "How do you know that people are blessed? Sanyang Kaitai is directly hitting", "How do you know that people can live long? Welcome to the sky and the sun is free of sorrow"; "How do you know that people are poor and poor? Poor? The land of North Yin is a cold door."

The sunlight that directly enters the room not only makes the human body healthy and functional, but also makes people comfortable and invigorating, and improves labor efficiency. It also has a certain sterilization and anti-rickets effect, so it is necessary to open the window frequently. A layer of clean window glass can transmit ultraviolet rays, but 60% to 65% of the ultraviolet rays are reflected and absorbed by the glass. Unclean glass with dust can reduce the incidence of light by 40%, so always keep the window glass clean so that there is enough sunlight even when the window is closed.

Nowadays, the daylighting function of most residential windows will be better, but the ventilation function is sometimes discounted. The position of opening windows cannot form effective convection and circulation in the room. Therefore, the position and size of the opening of the window must take into account the three major aspects of ventilation, lighting, and energy saving.

Height of window

The height of the window (mainly the upper edge) must be higher than the door.

The windows should be opened as high as possible. Because of the high opening of the window, the light can be evened, which is conducive to the generation of soft uniform light. If the window is too low, the light will concentrate on a certain part, which is not conducive to light diffusion.

Orientation of the window

East window, Kyrgyzstan. The morning sun can directly shine in.

Southeast window, Kyrgyzstan. The morning sun can directly shine in.

South window, Kyrgyzstan. There is a cool breeze in the summer and sunlight in the winter, forming an indoor microclimate that is warm in winter and cool in summer.

Southwest window, flat. The sun is slanting to the west, the ultraviolet rays are weakened, and the bactericidal power is also weakened, and it is a bit westward. It is the location where corruption occurs. In ancient times, it was called the "liguimen". It is better to open the window in the unopened area, and don't open it too much.

West window, flat. Xi Zhao. The windows should not be opened too wide, and it is best to hang curtains in summer.

Northwest window, flat. Because the northwest is the stem position, the supreme position, it is best not to open the window. If it is necessary to open the window for daylighting and ventilation, open the window higher and smaller.

North window, flat. In summer, the south window is the air inlet for gentle breeze, and the north window is the air outlet, forming north-south convection; in winter, the north window becomes the entrance of cold air, so it is better to use closed windows that are easy to open and close.

Northeast window, fierce. The northeast back sun, with moisture, is the location where corruption occurs. In ancient times, it was called the "monster of the watch". If you have to open the window in this position, you should open it on the Yin's part, try to open it as small as possible, and preferably a closed window.

Harmony home formula

It’s good to see the distant view from the window,

Blessed are Xiangyang people.

There is a cool breeze blowing in the summer,

Worry-free in winter and sun.
