Social housing improvement factors for upgrading processes

A large social housing (SH) stock exists around the world, and many developments need upgrading for various reasons. Upgrading demands careful planning and execution with specific improvement interventions that require clear, socially conscious, and technological as well as environmental objectives. In mandatory processes, top-down government improvement initiatives are mandated by directives, while users in non-mandatory processes instigate a bottom-up upgrading. In this context, people improve their living conditions and undertake self-built reforms, often at high costs due to a lack of planning and technical support. This study investigated upgrading interventions and improvement factors for SH. We discuss upgrading with a literature review to understand the operational improvements with user quality of life in mind. Results identify improvement interventions on topics of Energy and Resource Efficiency; Housing Quality and Comfort; Building Systems and Infrastructure; Health, Psychological and Social Wellbeing; Green and Open Spaces; Functional Design and Accessibility; Mobility and Services; Waste and Water Management. The study classified interventions by their complexity of execution. Frameworks for both mandatory and non-mandatory upgrading processes were created, and the impacts of SH upgrades are outlined. The contributions support decision-making roadmaps for upgrading processes to improve SH.

全球范围内存在大量社会住房（Social Housing, SH）存量，诸多已建成的社会住房项目因各类缘由亟需提质改造。此类改造工作需开展严谨的规划与实施，搭配针对性的改善举措，且需明确兼顾社会关怀、技术与环境层面的目标。在强制改造流程中，政府自上而下的改善举措由政策指令强制推行；而在非强制流程中，则由住户自下而上发起改造工作。在此类场景下，住户为改善居住条件开展自主改造，但因缺乏规划与技术支持，往往需承担高昂的改造成本。本研究针对社会住房的提质改造举措及其影响因素展开调研。本研究通过文献综述探讨社会住房提质改造工作，以期明晰以提升住户生活质量为导向的实操性优化方案。研究结果明确了八大类改善举措，涵盖能源与资源效率、住房品质与居住舒适度、建筑系统与基础设施、健康、心理与社会福祉、绿色开放空间、功能设计与无障碍通行、出行配套与公共服务，以及废弃物与水资源管理等主题。本研究依据改造实施的复杂程度对上述举措进行分类，分别构建了强制与非强制两类改造流程的实施框架，并梳理了社会住房提质改造所产生的各类影响。本研究的成果可为社会住房提质改造的决策路径提供支撑，助力社会住房品质提升。
