For example, it is clear in the exposure draft that "the height of the floor shall not be less than 3.00 meters; The indoor clear height of the bedroom and living room should not be less than 2.50 meters. " Compared with the current code, the height and clear height standards are increased by 20 cm and 10 cm respectively. The higher the storey height, the larger the living space. At present, the height of some old residential areas is slightly lower, which affects people's living experience. Many property buyers have had this experience when buying second-hand houses. Paying attention to the improvement of storey height standards in the draft for comments can effectively improve the living comfort of residents. Industry experts told reporters that through investigation, it was found that the average height of a considerable number of high-rise residential floors in the city has actually reached 3 meters. The revision of this standard is actually a concentrated reflection and summary of the current practice. However, a higher storey height may increase the cost of real estate development enterprises. If the story is slightly lower, high-rise residential buildings with more stories may have 1 story or more for sale. "Residential Project Specification" has mandatory characteristics, once implemented, all market participants must abide by it.
There are also some requirements related to living comfort. For example, in daily life, many people are troubled because the floor is not soundproof, which leads to many neighborhood disputes. If the floor is thicker, the sound insulation effect may be better. In the draft for comments, it is clear that "the thickness of reinforced concrete floor of new residential buildings should not be less than 100 mm". Another example is, "the use area of the bedroom should not be less than 5 square meters; When there is no living room in a residential apartment, the use area of the bedroom should not be less than 9 square meters; The use area of the kitchen should not be less than 3.5 square meters; The use area of toilets with centralized toilets, bathtubs and washbasins should not be less than 2.5 square meters. " Not only the area of related space has specific numerical provisions, but also the lighting that people pay attention to has clear requirements. The exposure draft is clear that "each house should have at least one living space to get winter sunshine"; "The bedroom, living room and kitchen of every house should have direct lighting".
The regulations on elevators have also attracted much attention. In the draft for comments, it is clear that "the entrance floor is a residential building with two or more floors, and each set should be equipped with at least 1 elevator", which indicates that elevators may become the standard of urban housing in the future. It is generally analyzed in the industry that elevators, as the standard of residential buildings, echo the aging trend of the current society. At the same time, the exposure draft also stipulates that "for residential buildings with four or more floors, or the height of floors above the outdoor design ground exceeds 9 meters, each unit should at least be equipped with 1 elevator that can accommodate stretchers". In recent years, because the elevator is too narrow and stretchers are difficult to enter, there are often news that residents are facing difficulties in emergency rescue. The requirements of the exposure draft for elevators are more precise. By improving technical standards, it is conducive to effectively protecting the lives, health and safety of the broad masses of people.
While clearly regulating the interior of the house, the requirements of the draft for comments on the living environment around the community are also very clear. For example, with the increase of electric vehicles, there is a greater demand for charging piles. The exposure draft clearly stated that "charging facilities for new energy vehicles should be configured or installation conditions should be reserved". Green space not only beautifies the environment, but also becomes a good place for urban residents' leisure sports. The exposure draft is also clear about the setting of green space. Including "concentrated green space should be set up in residential blocks"; The width of concentrated green space should not be less than 8 meters ".In concentrated green space, the area of green space outside the sunshine shadow line of standard buildings should not be less than 1/3, and places for elderly children's activities should be set up".
Wang, a senior engineer of China Institute of Building Research Co., Ltd. said: "The exposure draft is the bottom line requirement, and there are many places that are appropriately improved than the current standards, which is conducive to serving the people's better life and enhancing their sense of acquisition and happiness." Future housing projects aim at applicability, economy, green and beauty. I believe that with the further improvement and promotion of relevant standards, living life will be more convenient, comfortable and warm.
