Circular In, Circular Out: Applying Circular Design in a Pop-Up Public Building in Lund

Background and Aim: Circular design, emphasizing sustainability and resource efficiency across a building's lifecycle,has become increasingly critical in addressing global environmental challenges. This paper examines the implementationof circular principles in a temporary kindergarten as a public building project in Lund, Sweden. The aim is to demonstratehow these principles can be integrated from conceptualization through to end-of-life considerations, highlighting theirpotential impact on environmental sustainability.Methods and Data: The project's approach involved research into circular design methodologies and sustainable buildingpractices. Methods included design-for-disassembly and design-for-circularity strategies to enhance material reuse andminimize waste generation. Data collection encompassed regulatory compliance, material sourcing, and stakeholderengagement processes.Findings: Innovative solutions in designing light weight and affordable temporary modular construction techniques andusing parametric modelling and lifecycle impact as a tool to ensure low carbon circular design. The findings contributeto a deeper understanding of practical applications of circular design in urban development contexts. The studyhighlighted the importance of holistic design approaches that prioritize environmental responsibility.Theoretical/Practical/Societal Implications: Theoretical implications highlight the transformative potential ofintegrating circular principles into architectural practices, fostering sustainable urban development. Practically, this studydemonstrates the feasibility of adopting circular design strategies within existing regulatory frameworks, promotingenvironmental stewardship and community well-being. Societally, the study advances discourse on sustainablearchitecture by showcasing Lund, Sweden, as a model for implementing comprehensive circular design strategies inpublic infrastructure projects.
