In the current urban system, characterised by a one-directional flow of resources from the rural environment to the cities, the construction sector plays a critical role in supporting the transition from a linear to a circular economy. In this framework, temporary pop-up environments act as an innovative and sustainable type of living system. These are structures conceived as temporary from the outset, based on characteristics like flexible light-weight technologies, fast and easy assembly operations, temporary occupation of the ground and adaptability to different uses, needs and target groups. Great importance is placed on construction reversibility and environmental sustainability. In the framework of the interdisciplinary research project 'Urban Pop-Up Housing Environments and Their Potential as Local Innovation Systems', six scenarios of application for temporary pop-up environments for the city of Vienna have been developed, taking into consideration technical, urban and social aspects, on the basis of local uses and climatic conditions. In order to explore drivers and barriers of the scenarios regarding the transferability of the concepts, online questionnaire sessions were conducted with an international audience. The feedback obtained by the participants allowed an analysis of the applicability of the concepts to other urban environments under comparable conditions at the international level. The paper presents the results obtained from the questionnaire sessions, allowing insight on the international perception of temporary pop-up environments and, specifically, strengths and weaknesses of the scenarios, as well as their possible applicability in the local contexts of the respondents. It was observed that while the perceptions of what requirements temporary housing must fulfil in order to be sustainable are quite uniform among the experts, the identified barriers for implementation within the different international contexts differed greatly. The designs of these temporary housing scenarios, which rely heavily on local resources and systems, are strongly interwoven with the fabric and conditions of the city they were conceptualised for. While this serves to promote the sustainability of these solutions, it poses a particular challenge for the international transferability, requiring heavy adaptation for other contexts.
在当前以资源从农村环境单向流向城市为特征的城市体系中，建筑行业在支持从线性经济向循环经济的转型中发挥着关键作用。在此框架下，临时弹出式环境作为一种创新且可持续的生活系统类型。这些结构从一开始就被设想为临时性的，基于诸如灵活的轻质技术、快速简便的组装操作、对地面的临时占用以及对不同用途、需求和目标群体的适应性等特征。高度重视建筑的可逆性和环境可持续性。在跨学科研究项目“城市弹出式住房环境及其作为地方创新系统的潜力”框架内，考虑到技术、城市和社会方面，并基于当地用途和气候条件，为维也纳市开发了六种临时弹出式环境的应用场景。为了探究这些场景在概念可转移性方面的驱动因素和障碍，针对国际受众开展了在线问卷调查。参与者提供的反馈使得能够分析这些概念在国际层面类似条件下对其他城市环境的适用性。本文呈现了问卷调查的结果，让人了解国际上对临时弹出式环境的看法，特别是各场景的优缺点，以及它们在受访者当地背景下的可能适用性。据观察，虽然专家们对于临时住房要实现可持续性必须满足哪些要求的看法相当一致，但在不同国际背景下确定的实施障碍却有很大差异。这些临时住房场景的设计严重依赖当地资源和系统，与它们所针对的城市的结构和条件紧密交织。虽然这有助于促进这些解决方案的可持续性，但对国际可转移性构成了特殊挑战，需要针对其他背景进行大量调整。
