All over the world, populations are ageing. People live longer and are generally in better health, free from disabilities and impairments, than previous generations. In the member states of the Organisation for Economic Co-operation and Development, the population share of older adults is expected to rise to 25.1% in 2050. Cities in particular have large numbers of older inhabitants, and understanding the relationship between population ageing, urban change, in conjunction with the need to develop supportive urban communities and housing is a major challenge. Buffel et al. described the history of the effort by the World Health Organization (WHO) to engage and assist cities and communities in becoming more ‘age-friendly’, through the Global Age-Friendly Cities Guide and a companion ‘Checklist of Essential Features of Age-Friendly Cities’. An age-friendly city or community optimizes opportunities for health, participation and security in order to enhance the quality of life of residents as they age. Housing, as well as outdoor spaces and buildings are two of the eight domains of age-friendly cities and communities. The WHO age-friendly cities and communities model provides guidance and direction for policy and practice, relating to the design of services and the urban environment and is intended to provoke new lines of thought. One of such lines of thought is the explicit consideration of technology, both for use by older people directly, and to control the indoor and built environment, as technology has become an integral aspect of our daily lives and is all around us. In the context of the built environment, we see the everyday emergence of technology and associated information communication technologies such as virtual assistants, which can positively impact on the age-friendly home ecosystem. Such home ecosystems that incorporate these types of technologies can offer additional support within that specific environment including medication and calendar reminders, make telephone calls, play music and manage to-do lists. Within each domain of the WHO model, there are numerous points associated to technology and other key features. The features and issues can also be the basis for technology use and implementation within a smart age-friendly ecosystem framework, from modifications within housing developments to effective communication and information sharing. Housing that is suitable for older people is ideally barrier-free and may include a large number of home modifications that are available to adapt dwellings. Easy-access and single-level dwellings are needed to house the growing group of older people, who may be at a higher risk of reduced mobility and who are more prone to falls. This does not mean that all homes for older people, especially for the ‘younger’ cohorts, should be full of unnecessary and unwanted modifications which can contribute to stigma. Homes need to be designed for flexibility, so that they can be adjusted when the need arises, for instance, during rehabilitation after a fall incident. Ultimately, the agendas of the age-friendly cities and communities’ movement, and the smart cities communities may go hand in hand. A smart city or town is an urban area that utilises and deploys various electronic Internet of Things (IoT) devices and sensors, which have the ability to collect data and utilise the data in an attempt to provide efficient and smarter resources to residents and communities. A myriad of data can be collected from the public and private transport, to

老龄化社区、支持性住房和有利的建筑环境

在世界各地，人口都在老龄化。与前几代人相比，人们的寿命更长，总体健康状况更好，没有残疾和损伤。在经济合作与发展组织成员国，预计到 2050 年老年人口比例将上升至 25.1%。尤其是城市拥有大量老年居民，了解人口老龄化、城市变化以及发展支持性城市社区和住房的需要是一项重大挑战。布菲尔等人。描述了世界卫生组织 (WHO) 通过《全球老年友好城市指南》和随附的“老年友好型城市基本特征清单”参与和协助城市和社区变得更加“老年友好型”的努力的历史城市”。老年友好型城市或社区可以优化健康、参与和安全的机会，以提高居民随着年龄增长的生活质量。住房以及户外空间和建筑物是老年友好城市和社区的八个领域中的两个。世卫组织关爱老人城市和社区模式为与服务设计和城市环境相关的政策和实践提供指导和方向，旨在激发新的思路。其中一种思路是明确考虑技术，既可以直接供老年人使用，也可以控制室内和建筑环境，因为技术已成为我们日常生活中不可或缺的一部分，并且无处不在。在建筑环境的背景下，我们看到技术和相关信息通信技术（例如虚拟助手）的日常出现，它们可以对老年人友好的家庭生态系统产生积极影响。结合这些类型技术的家庭生态系统可以在特定环境中提供额外支持，包括药物和日历提醒、拨打电话、播放音乐和管理待办事项列表。在 WHO 模型的每个领域中，都有许多与技术和其他关键特征相关的要点。这些特征和问题也可以成为智能老年友好生态系统框架内技术使用和实施的基础，从住房开发中的改造到有效的沟通和信息共享。适合老年人的住房最好是无障碍的，并且可能包括大量可用于改造住房的房屋改造。需要方便的单层住宅来容纳越来越多的老年人，他们可能面临更高的行动不便风险和更容易跌倒的风险。这并不意味着所有老年人的房屋，尤其是“年轻”群体，都应该充满不必要和不需要的改造，这可能会导致耻辱。房屋的设计需要具有灵活性，以便在需要时进行调整，例如在跌倒事故后的康复期间。最终，老年友好城市和社区运动的议程与智慧城市社区可能齐头并进。智慧城市或城镇是利用和部署各种电子物联网 (IoT) 设备和传感器的城市区域，这些设备和传感器具有收集数据和利用数据的能力，试图为居民和社区提供更高效、更智能的资源。可以从公共和私人交通工具中收集大量数据，以
