楼市重磅！“好房子”标准，公布！

Core Viewpoint - The newly released national standard "Residential Project Specification" aims to ensure safety, comfort, sustainability, and intelligence in residential construction, effective from May 1, 2023 [1][2]. Group 1: Construction Requirements - Residential projects must adhere to principles of economic rationality, safety, human-centered design, green low-carbon practices, and technological empowerment [2]. - The specification mandates that residential buildings meet accessibility design principles and performance requirements for ventilation, daylighting, sound insulation, waterproofing, moisture-proofing, thermal insulation, and heat preservation [2]. - New residential buildings must have a minimum floor height of 3.00m, with specific room height requirements for bedrooms, living rooms, kitchens, and bathrooms [2]. Group 2: Public Space and Facilities - For residential buildings with four or more stories, at least one elevator must be provided per unit; for buildings with twelve or more stories, at least two elevators are required [2]. - The specification also requires that public mobile communication signals cover public spaces and elevator cabins [2]. Group 3: Indoor Environment - The standard enhances sound insulation performance between units and sets noise limits for structural noise and drainage noise affecting living spaces [3]. - Basic performance requirements for winter insulation, summer heat insulation, and building ventilation are also outlined [4]. Group 4: Overall Impact - The new specification is a mandatory engineering construction standard aimed at safeguarding basic housing conditions and living environments for residents [4]. - Compared to previous standards from 2005 and 2011, the new specification emphasizes a systematic approach to residential projects, addressing height, density, aging requirements, noise control, and thermal environment improvements, which are significant for the long-term high-quality development of residential construction [4].
