Or when there are houses on both sides and walls on the other side, the open space in the middle is generally small and mainly used for lighting and ventilation of the house. Light wells are added at the front and rear ends of the house, the intersection of the house and the wall, and the atrium for lighting.
Extended data:
Natural lighting A satisfactory house has very important lighting conditions. A well-lit house can save energy, make people feel comfortable and facilitate the layout of various functions in the house. Otherwise, living in the dark for a long time and relying on artificial lighting will be very unfavorable to people's physical and mental health.
Lighting can be divided into direct lighting and indirect lighting. Direct lighting refers to directly opening the lighting window. Indirect lighting refers to the closed corridor (usually the veranda), the hall and kitchen with direct lighting. Some kitchens, halls and bathrooms use small patios for lighting, and the lighting effect is like indirect lighting.
There are three ways to arrange the top of the lighting well: if it is used in the basement, it will be covered with glass, so it can only light and give up the ventilation function.
Drainage should be carried out at the bottom of the light well. If it is a light well without a top cover, drainage must be arranged to avoid blockage caused by poor drainage in heavy rain. As can be seen at the villa site, under normal circumstances, there is drainage at both ends of the lighting well.
