On March 31st, the national standard "Residential Project Code" (hereinafter referred to as the "Code") was released. With the goals of safety, comfort, greenness and intelligence, it stipulates the construction, use and maintenance of residential projects in terms of scale, layout, function, performance and key technical measures.

The norms set out the bottom-line requirements for residential projects. It is learned that the regulations will come into effect on May 1st this year. What are the notable contents among them? What upgrades will it bring to the living experience of the common people? The reporter conducted an interview.

Focus point ① : The floor height of newly built residential buildings should not be less than 3 meters

The floor height is the vertical distance between two adjacent floors above and below. According to the standards, the floor height of newly built residential buildings is raised to "no less than 3 meters". Zeng Yu, the chief architect of the Architectural Design Institute of China Academy of Building Research Co., LTD., introduced that the standard has raised the floor height by 20 centimeters, which can provide better natural lighting and ventilation indoors, offer residents a better spatial experience, provide conditions for diverse decoration, and enhance functional flexibility.

Focus Point ② : Elevators are installed in residential buildings with four floors or more

The regulations require that elevators be installed in residential buildings with four floors or more.

Zeng Yu said that China has entered a moderately aging society, and it is rather difficult for the elderly to go up and down stairs. Installing elevators starting from the fourth floor can meet the needs of the elderly and also facilitate residents' daily travel and the transportation of heavy objects.

At present, a large number of multi-storey residential buildings have the demand for installing elevators, but due to various constraints, it is very difficult to implement. "Stipulating that new residential buildings should have elevators starting from the fourth floor can basically cover the vast majority of residential buildings and avoid the problem of installing elevators in the future." " Zeng Yu introduced.

Not only that, the regulations also require that the public mobile communication signals of residential buildings can cover public Spaces and elevator cabins. In case of emergencies, timely external contact can be made to enhance the sense of security of residents.

Focus ③ : Enhance the sound insulation performance of walls and floor slabs

According to the research, there are relatively many complaints caused by noise. This specification has enhanced the air sound insulation performance between the rooms on both sides of the partition walls and partition floor slabs of the bedrooms and living rooms, as well as the impact sound insulation performance of the partition floor slabs. In addition, noise limit requirements have been set for structural noise transmitted from building equipment to bedrooms and living rooms, as well as noise from bathroom drainage.

Yan Guojun, director of the Sound Environment Research Center of China Academy of Building Research Co., LTD., introduced that the standards have raised the requirements for the sound environment indicators of residential buildings, which can effectively reduce noise interference.

Focus ④ : The system puts forward requirements for barrier-free and elderly-friendly construction

This specification puts forward a series of requirements for barrier-free and elderly-friendly construction. For instance, it is required that handrails should be installed beside the toilet bowls and showers in the bathroom or that installation conditions be reserved. Each residential unit is required to have at least one barrier-free public entrance and exit. Raise the clear width requirements for household doors and bathroom doors to facilitate the entry and exit of elderly people or those in wheelchairs. Put forward requirements such as the size of the elevator car and the height of the emergency call button.

Point ⑤ : Each residence has rooms that meet the sunlight standards

The quality of the indoor thermal environment is related to the perception of "cold and warmth", and it is a key performance indicator for ensuring human health and comfort and enhancing the satisfaction of living. The standards put forward basic performance requirements for residential buildings from three aspects: winter insulation, summer heat insulation and building ventilation.

In areas with hot summers and cold winters, summers are hot and winters are cold and damp. From the perspective of livability, certain measures need to be taken to ensure the indoor thermal environment. Wang Qingqin, a professor-level senior engineer from China Academy of Building Research Co., LTD., introduced that this regulation takes into account the winter heating needs of the people in hot summer and cold winter regions, such as the Yangtze River Basin, and stipulates that residential buildings in hot summer and cold winter regions should be equipped with heating and air conditioning facilities or reserve installation positions.

Sunlight exposure is of great significance to people's physical and mental health. This regulation requires that each residential unit have rooms that meet the sunlight standards. Experts say that this also requires that the standard design of residential projects not only control the building spacing well, but also optimize the floor plan design and take into account the reasonable layout of indoor space.

The regulations also make relevant provisions for potential hazards such as injuries caused by falling objects from heights. For instance, they require that railings have measures to prevent climbing and falling objects, and that canopies be installed at the entrances and exits of units. The standards also require that the outdoor units of air conditioners be installed on dedicated platforms.

In terms of electrical aspects, the regulations stipulate the setting requirements and quantity of power sockets for each residential unit. Besides specifying the setting of power sockets for fixed household appliances such as washing machines, refrigerators, and range hoods, the number of power sockets in the kitchen has also been increased to enhance the convenience of use.

The new standards, based on the practical experience of residential project construction in China in recent years and after an assessment of the implementation of current residential standards, and through extensive solicitation of opinions and thorough argumentation, propose that adhering to the principles of "economic rationality, safety and durability, people-oriented, health and comfort, adaptation to local conditions, green and low-carbon, technology empowerment, and smart convenience" will provide more powerful support for the high-quality development of urban residential buildings. A responsible person from a relevant department of the Ministry of Housing and Urban-Rural Development said.
