2. 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.
3. 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.
At present, the conventional way to solve the problem of "west trunk" is to use curtains with sunshade curtains. This method can prevent the sun's heat from entering to a certain extent, but its disadvantages are also obvious. There is no natural light in the room at all, and people feel depressed in the room.
