Resource-driven design; exploring an informed design process in the reuse of structural concrete elements

Abstract

This master’s thesis explores the integration of reused structural concrete elements within contemporary architectural practice, focusing on enhancing resource efficiency and reducing the construction industry’s environmental impact. Acknowledging the significant contribution of the Architecture, Engineering, and Construction (AEC) industry to global carbon dioxide emissions, with concrete production as an essential factor, this research seeks sustainable alternatives to traditional methods. Specifically, it addresses the potential for reusing entire concrete elements to mitigate environmental impacts. The study examines the challenges and opportunities of reusing structural concrete elements through a literature review and collaboration with industry stakeholders. It introduces the development of a digital tool, specifically a plugin for Grasshopper in Rhino, designed to streamline the integration of reused elements into architectural designs. This tool hopes to transform the design process by prioritising resource efficiency and incorporating relevant data. The thesis focuses on the practical application of hollow-core slabs and load-bearing concrete wall elements, investigating their reuse potential. The results are structured into three main parts: an explanation of the Grasshopper tool and its functionalities, the evaluation of data management within the design process, and the implementation of the tool in a local plan in Bergsjön. This involved the creation of load-bearing modules that underpinned the implementations, leading to the development of three architectural projects: a townhouse, a small apartment building, and a larger apartment complex. Through its findings, the thesis aims to establish a design process that effectively integrates the reuse of structural concrete components. The study underscores the importance of digital tools in enhancing the feasibility of reusing concrete elements and advocates for increased industry standardisation to overcome current technical and regulatory challenges
