In the spacious dwellings, the occupants are surrounded by their personal aura. When a dwelling is too large, it takes too much energy to maintain this aura, which can adversely affect the body of the occupants. A high-quality building layout requires proper use of space without wasting it. For example, although the Forbidden City has 9,999.5 rooms, the emperor's bedroom space is relatively small, and the bed curtain further compresses the sleeping space, which helps to save the owner's energy and keep him energetic.
Scientific research has shown that in order to ensure that indoor air is fresh and clean, furniture should be arranged reasonably, and sufficient space for activities and rest should be reserved to avoid overcrowding, so as to reduce the spread of diseases. Everyone should have adequate living space.
Usually, the living space occupies 60%~70% of the whole residential floor area, and this proportion is determined according to factors such as the standard air volume of the person. For example, an adult needs a volume of 10 cubic meters of air to breathe under static conditions, and will also emit 0.35~0.42 cubic meters of carbon dioxide every day. When you are doing physical activity or exercise, the amount of carbon dioxide exhaled increases accordingly. Taking into account hygienic standards, the concentration of indoor carbon dioxide should be controlled to less than 1% of the amount of indoor air entering the room per hour. According to these standards, the standard air volume for a person is about 33 cubic meters, and after deducting the space occupied by furniture, the standard air volume is generally 30 cubic meters per hour for adults and half for children.
Starting from the standard air volume of people, the volume of per capita living space should be 20~25 cubic meters (if all are adults, it is recommended to be 25~30 cubic meters). Considering factors such as hygiene and architecture, the per capita living area is 9 square meters, of which the bedroom occupies 6 cubic meters and the day activity room occupies 3 cubic meters. Therefore, the Code for the Design of Residential Buildings clearly states that the area of the bedroom should not be less than 12 square meters (17 square meters for the large room of a specially designed residence, 9 square meters for the middle room, and 6 square meters for the small room).
On the other hand, an excessively large residential area can cause housewives to be overburdened when it comes to cleaning. Studies have shown that it takes time to recover after cleaning, and an area of more than 60~100 square meters may over-fatigue housewives, thus increasing the risk of disease.
In addition, there may be vacant rooms in oversized dwellings, which are often underlit, poorly ventilated, and lack "popularity" that tend to become damp, dim, and accumulate dust, which accelerates the growth of bacteria. This kind of long-term uninhabited room will give people a cold and uncomfortable feeling when opened, especially in rooms decorated with modern materials, because harmful gases are difficult to dissipate, the pollution of the home environment is more serious, and it poses a threat to human health.
From a psychological point of view, too much space can be unstable for the occupants. Especially in modern multi-storey and high-rise residences, the floor height is generally not high, and too large spaces are more likely to produce a sense of oppression.
"The Yellow Emperor's House Sutra" clearly pointed out that "the house has five voids, and the house is less than one void." "Therefore, the residential area must be moderate. Especially for modern city homes and multi-storey houses in small towns, due to the limitation of floor height, if the living room (or with a dining room) is too large and the ceiling is low, it is more likely to cause a sense of oppression. In some homes, living rooms with dining rooms tend to have too large aspect and aspect ratios, which can cause echo problems and can give the illusion of being perceived.
Residential construction standards mainly include area standards and functional standards. Area serves function, and countries are striving to pursue better residential functions under the appropriate area. In recent years, there has been no significant expansion of the floor area of new residential buildings in developed countries. In contrast, the residential area of the mainland has a tendency to increase, and the 150~200 square meter units account for a large share. It's a misleading impression on consumers that it's the large, ultra-luxurious homes that are attractive. However, it is clear from the above analysis that people can feel small and uncomfortable in an oversized dwelling. According to a comprehensive analysis of various aspects, for a large number of families of 3 in the mainland, the residential area of 70~90 square meters can already meet the basic needs of daily life
