A systematic literature review of architecture-related dew and fog harvesting

Abstract

Dew and fog harvesting had been the topic of numerous studies since the 2000s to address the global water crisis brought on by climate change, as an alternative and sustainable solution. Though this topic has many connections to architectural science, it is nonetheless alien to academics and practitioners with architectural backgrounds. What research focuses had been done? What research methodologies were employed? What implications and limitations were discovered? This study addresses these questions by conducting a systematic literature review. This study discovered that the effectiveness and efficiency of planar shape-based fog nets and dew condensers continued to dominate the research focus. Although several studies have begun to consider the forms of three-dimensional and biomimicry. One study also started researching the application of this technology to urban settings apart from rural areas affected by water scarcity. The most employed methodology in this research was design testing and review. Some models, prototypes, and developments are implicated as best practices, although the limitations of these studies lay in the physical local context, material selection, methodologies, scalability, water quality, and water quantity. The results of this review provide direction for further research in Indonesia to consider the use of harvesting combination systems in three dimensions form with passive systems and low tech. Moreover, this discovery also opens opportunities for the use of vernacular or traditional architecture and local natural materials that have not been discussed by previous studies.
