Research trends and design strategies for bamboo architecture: A bibliometric and systematic review

With respect to carbon neutrality, bamboo-based materials have attracted extensive attention in architectural design. However, the existing reviews typically focus on materials and structural components, and do not reach the level of architectural design. The aim of this review is to provide reasonable recommendations in response to these limitations with the following specific objectives: (1) identifying the research trends in bamboo architecture via a systematic review process and providing a mapping of the knowledge domains in this area; (2) summarizing the design strategies regarding bamboo architecture through a literature review, expert interviews, and field investigations using a meta-analysis method; and (3) identifying existing research directions and gaps for the recommendation of the future directions for bamboo architecture design. Through systematic synthesis and data visualization, this review contributes to the area of bamboo architecture design in terms of both scientific research trends and practical design strategies. More importantly, this work reviews not only articles but also typical case studies via expert interviews and field investigations. Finally, future directions for bamboo architecture design, including sustainability, cost, and comfort, are provided to achieve the research goals.
