Residential Design Standards" to be implemented in June Multi-storey housing shall be installed with elevators

　　Multi-story residential buildings must be set up elevators, high-rise residential must be set up refuge floors, indoor air quality of fully furnished rooms are clearly defined and included as mandatory provisions, moderate relaxation of restrictions on the orientation and spacing of commercial housing, new residential energy saving, electricity saving, water saving must meet the standards ...... much-anticipated Shanghai Engineering Construction Code "Residential Design Standards" has been revised by the Shanghai Urban and Rural Construction and Management Committee and will be officially implemented from June 1, 2014. The new version of the standard in the summary of the original standard since the implementation of lessons learned based on a comprehensive revision, optimization and improvement.

　　More than 100 meters high rise to set up an evacuation floor

　　Based on the lessons learned from residential fires, the new residential design standards also clarify that high-rise residential buildings over 100 meters in height should be set up with an evacuation floor (area) for people to evacuate and take refuge in the event of a fire; the evacuation floor should not be set up with residential rooms, and ventilation conditions should be particularly good. The net area of the evacuation floor is calculated at 3 people per square meter, which is higher than the national standard of 5 people per square meter. "The reason for this is to consider the human mood when encountering a disaster is prone to irritability, in the possible conditions of appropriate relaxation of the area, conducive to creating a more spacious and comfortable environment to calm the mood of the evacuees, conducive to rescue." Chen Huanning, a professor at the Shanghai Institute of Architectural Design, said.

　　Fire lanes in residential areas

　　The new standard also requires fire lanes, firefighting landing surfaces and firefighting landing sites to be set up in residential areas of low-rise, multi-storey and mid-rise residences. "Through the analysis of residential fire cases in recent years, once the fire in the residential area, it is vital for fire engines to enter the residential area in time to put out the fire, therefore, this amendment further clarifies the requirements for setting up fire lanes, and the design of lane width and turning radius are clearly defined." Chen Huaning said.

　　Residential design will try east-west

　　The new version of the standard also moderately relaxed the residential orientation and spacing and other restrictions, the previous residential design requirements for the basic north-south, the future east-west can also try. Experts explained that, taking into account that Shanghai is an international mega-city, land resources are very scarce, in order to more reasonable use of land resources, give full play to the city space effect, the revision moderately relaxed the direction and spacing of commercial residential restrictions, so that the general plan design of various types of residential layout in a variety of forms, and at the same time in line with the relevant provisions of urban planning management in Shanghai.

　　No less than two elevators for high-rise residential buildings

　　In order to meet the convenience of the elderly to go up and down the stairs, the new standard specifically provides that multi-storey and above residences should be set up elevators. For a long time, the country requires more than 6 floors or 16 meters above the residential must be set up elevators, but with the development of China's economy and China's society into the aging stage, aging at home has become a common phenomenon, the new standards revised in Shanghai in the country's first clear provisions of 4-6 floors of multi-story residential should also be set up elevators, and as mandatory provisions. This is the first time in Shanghai on the design requirements of new multi-story residential buildings should be set up elevator provisions. This not only facilitates the elderly and the disabled to travel without obstacles, but also solves the increase of multi-storey residential buildings without elevators from the source, and reduces the pressure for the city to implement a large number of multi-storey residential projects with elevators. Provisions also require twelve floors and above the high-rise residential, the number of elevators set not less than two, one of the elevator should be able to accommodate a stretcher.

　　Specify the indoor pollutant limits

　　In addition to more reasonable requirements for noise and energy saving, the amendment also adds "indoor air quality of fully furnished rooms" and specifies the limits of indoor air pollutants according to national and Shanghai standards, and is clearly mandatory.

　　The new design standard also attaches importance to energy saving, electricity saving and water saving design from various aspects. In terms of energy saving, it is clearly stipulated that new residential buildings must implement the city's energy-saving standards to achieve energy savings of more than 60 percent. In terms of electricity saving, it is clearly stipulated that each household should be set up in separate meters, and according to the size of the household area, each household should control the electricity consumption; in the building, elevator room and public walkways and other parts must use energy-saving lamps and lanterns. In terms of water conservation, the maximum daily water consumption per person is clearly stipulated.
