Core Viewpoint - The new "Residential Project Standards" issued by the Ministry of Housing and Urban-Rural Development aims to ensure safety, comfort, sustainability, and intelligence in residential construction, effective from May 1 this year [1][2]. Summary by Sections Basic Requirements - The new standards emphasize safety, durability, human-centered design, health, and comfort, as well as green and low-carbon principles [2]. - Residential projects must adhere to barrier-free design principles and meet various performance requirements such as ventilation, lighting, sound insulation, waterproofing, moisture-proofing, thermal insulation, and heat preservation [2]. Building Space - New residential buildings must have a minimum floor height of 3 meters, with living spaces like bedrooms and living rooms having a net height of at least 2.6 meters, and kitchens and bathrooms at least 2.2 meters [2]. - Minimum usable areas are specified: bedrooms must be at least 5 square meters, combined living and bedroom spaces at least 9 square meters, and the short side width of bedrooms must not be less than 1.80 meters [2]. Public Space - For residential buildings with four or more floors, each unit must have at least one elevator; for buildings with twelve or more floors, at least two elevators are required [2]. - The standards also mandate that public mobile communication signals must cover public spaces and elevator cabins [2]. Indoor Environment - The new standards enhance sound insulation performance between units and set noise limits for structural noise and drainage noise in living areas [3]. Performance Requirements - Basic performance requirements for residential buildings include winter insulation, summer heat insulation, and ventilation [4]. - The new standards are considered mandatory engineering construction regulations aimed at ensuring basic housing conditions and living environments for residents [4]. Comparison with Previous Standards - Compared to the 2005 and 2011 standards, the new regulations take a more holistic approach to residential projects, focusing on increasing floor heights, controlling density, refining elderly-friendly requirements, strengthening noise restrictions, and improving thermal environment standards [4].
