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].

住房城乡建设部3月3 1日发布国家标准《住宅项目规范》。规范将于今年5月1日起施行，要求 住宅项目建设应以安全、舒适、绿色、智慧为目标，遵循"经济合理、安全耐久，以人为本、 健康舒适，因地制宜、绿色低碳，科技赋能、智慧便利"的原则。 规范规定了新建住宅建筑层高不低于3米，4层及以上住宅设置电梯；提高了墙体和楼板隔声 性能；提高了户门、卫生间门的通行净宽；提高了阳台等临空处栏杆高度；要求公共移动通信 信号覆盖到公共空间和电梯轿厢内；要求空调室外机安装在专用平台；规定了不同气候区供 暖、空调设施设置要求等。 下一步，围绕好的材料、好的建造、好的服务，相信还会有更多的标准出台，就让我们拭目以 待。 三个关键词，带你看懂"好房子"新标准 第一个：电梯。 新标准将现行要求规定的7层起设置电梯，提升为4层起就要设置电梯，每个住宅单元应至少 设置1台电梯。 第二个：适老化。 新标准针对老龄化社会，对于如何满足适老的需求有很多设计： 第三个：噪声。 新的标准，结合大家长期以来比较关注的噪声扰民的问题，对噪声限值、隔声限值做出了要 求。简单来说，就是： 满足老年人需求。 便于出行和搬运重物。 有利于医疗救护。 避免后期再面临加 ...
