The choice of building orientation should meet the requirements of more sunshine in winter and avoiding too much radiation in summer. According to the geographical location of China, buildings facing south and their adjacent orientations can meet this requirement. However, due to the limitation of terrain or considering the overall planning and layout of the community, many houses are often located in the east-west direction, which makes some rooms in the building have the problem of west sunshine.
Lighting in the living room is very important. Dongyang light room can have enough lighting, but it's not too hot. Xiyang light room not only makes the living room more sunny and hotter, but also is not conducive to lighting.
Extended data
1. Every house facing the sun in the west is not ventilated and the wind does not enter the house in summer. In winter, the northwest wind blows, and even if the windows are closed, the wind will get into the house.
2. The intense sun exposure in summer will make the temperature of the room facing west rise a lot, and the huge heat released by the sun through the glass of the sun room will lead to the huge energy consumption of air conditioning operation and increase the electricity bill.
In a sunny house in summer afternoon, the walls will absorb heat, and at night, the heat will be emitted, which will evaporate a lot of oxygen in the house, leading to low mental state.
