“…One potential reuse driver is the scarcity of landfilling sites, which helps the environment by avoiding the dumping of reusable waste into landfills ( Chau et al, 2012 ; Chinda and Ammarapala, 2016 ). According to the literature, reuse can decrease the use of virgin materials and water consumption ( Aye et al, 2012 ; Densley Tingley et al, 2012 ; Sára et al, 2001 ; Tingley et al, 2017 ; Yeung et al, 2017 ). As mentioned in the introduction, because of the considerable advantages of reuse, components reuse can improve the environmental footprint of buildings worldwide.…”

“…As mentioned in the introduction, because of the considerable advantages of reuse, components reuse can improve the environmental footprint of buildings worldwide. By reusing building components, embodied energy and carbon of construction can be decreased ( Brütting et al, 2019 ; Klang et al, 2003 ; Tingley et al, 2017 ; Yeung et al, 2017 (among others)). Brütting et al (2019) show that a structure made with reused steel sections have considerably lower embodied energy and CO 2 emissions.…”

“…Environmental barriers. Although component reuse is identi-fied as a sustainable end-of-life treatment of the superstructure of a building (Brütting et al, 2019;Klang et al, 2003;Tingley et al, 2017;Yeung et al, 2017), there are concerns regarding the adverse effects of this practise due to the increased GHG emis-sions related to deconstruction activities and the transportation of recovered elements (Brambilla et al, 2019;Nußholz et al, 2019). Brambilla et al (2019) performed a study to evaluate the envi-ronmental impacts of various steel-concrete composite floor systems.…”

Widespread reuse of building components can promote the circularity of materials in the building sector. However, the reuse of building components is not yet a mainstream practise. Although there have been several studies on the factors affecting the reuse of building components, there is no single study that has tried to harmonize the circumstances affecting this intervention. Through a systematic literature review targeting peer-reviewed journal articles, this study intends to identify and stratify factors affecting the reuse of components of the superstructure of a building and eventually delineate correlations between these factors. Factors identified throughout this study are classified into six major categories and 23 sub-categories. Then the inter-dependencies between the barriers are studied by developing the correlation indices between the sub-categories. Results indicate that addressing the economic, social and regulatory barriers should be prioritized. Although the impact of barriers under perception, risk, compliance and market subcategories are very pronounced, the highest inter-dependency among the sub-categories is found between perception and risk. It suggests that the perception of the stakeholders about building components reuse is affected by the potential risks associated with this intervention.

An important share of building environmental impacts is embodied in load-bearing structures because of their large material mass and energy-intensive fabrication process. To reduce substantially material consumption and waste caused by the construction industry, structures can be designed and built with reused elements. Structural element reuse involves: element sourcing and deconstruction, reconditioning and transport. As these processes also generate environmental impacts, reuse might not always be preferred over new construction. This paper presents a method to design reticular structures with minimal environmental impact made from reused and new elements. The formulation given in this paper is based on a combination of Life Cycle Assessment (LCA) and discrete structural optimization. The LCA carried out in this work accounts for impacts generated from sourcing reclaimed elements to the assembly of the structure. Structural optimization is subject to stress constraints on element capacity and deflection limits for serviceability. Typical loading scenarios are considered. The method is applied to the design of three single-span steel trusses of different topology subject to 100 simulated stocks of reusable elements that have varying cross-sections and lengths. Benchmarks against minimum-weight solutions made solely from recycled steel show that this method produces structures with up to 56% lower environmental impact. Depending on stock availability, the lowest environmental impact is achieved through a combination of reused and new elements.
