“…The technical aspects, benefits and costs of reuse of materials and building components, through design for disassembly/deconstruction, have been widely studied in the available literature [92][93][94][95]. If designed properly, many of the elements used in a typical building could be in good enough condition, at the end of the service life of the building, to be reused for similar or other applications [78,91,96].…”

Estimation and Minimization of Embodied Carbon of Buildings: A Review

Building and construction is responsible for up to 30% of annual global greenhouse gas (GHG) emissions, commonly reported in carbon equivalent unit. Carbon emissions are incurred in all stages of a building's life cycle and are generally categorised into operating carbon and embodied carbon, each making varying contributions to the life cycle carbon depending on the building's characteristics. With recent advances in reducing the operating carbon of buildings, the available literature indicates a clear shift in attention towards investigating strategies to minimize embodied carbon. However, minimizing the embodied carbon of buildings is challenging and requires evaluating the effects of embodied carbon reduction strategies on the emissions incurred in different life cycle phases, as well as the operating carbon of the building. In this paper, the available literature on strategies for reducing the embodied carbon of buildings, as well as methods for estimating the embodied carbon of buildings, is reviewed and the strengths and weaknesses of each method are highlighted.

“…As a result, a large amount of DW are generated causing the waste of resources and serious environmental pollution. The other method is deconstruction (also named selective demolition) which stands for the careful dismantling of building elements so as to make as much recovery of construction materials, promoting reuse and recycling as much as possible (Rios, 2015;. Furthermore, materials reuse and recycle have provided an option to reduce the total amount of waste landfilled, save natural sources, prolong the life cycle of particular types of materials.…”

Waste materials generated from building demolition have become a great challenge to sustainable urban development due to its consumption of the limited landfill spaces, water pollution, energy consumption and harmful gas emissions. Proper management of demolition waste (DW) is a complex process and requires systematic thinking and analysis. Many methods have been proposed to study the environmental impact assessment of demolition waste management (DWM). However, it is found that the currently available studies pay little attention from the perspective of complex adaptive system (CAS) to consider the attitude and interaction of the heterogeneous stakeholders as well as the importance of green DWM which has a great influence on the effectiveness of DW management. The aim of this research is to simulate and explore how the change of attitude and the dynamic interaction among heterogeneous stakeholders can influence the environmental performance of DWM. To achieve this aim, a model for evaluating the environmental impact of DWM was developed by using an agent-based modeling (ABM) approach. The main factors considered in the model are the ratio of green deconstruction (i.e., building deconstruction) managers vs. conventional demolition (i.e. building destruction) managers, the ratio of green design managers (i.e. design for deconstruction) vs. conventional design managers, and the interaction behavior of heterogeneous stakeholders following the herd theory. In the model, the environmental impact assessment was quantified into four categories i.e. land resources, water resources, air resource and energy resources. The proposed model is demonstrated by using the data drawn from the Chinese construction industry. The results reveal that if the deconstruction method and the deconstruction oriented design are widely adopted by architects and engineers, the negative environmental impacts generated by DW can be reduced by at least 50%. Furthermore, the results provide valuable information for government departments to make decisions on how to improve environmental performance of DWM.

“…Quantities and proportions of waste vary greatly between countries, however in the European Union, construction and demolition waste accounts for approximately 34% of total solid waste (Van Ewijk & Stegemann, 2016). The USA generates 160 million tons of construction and demolition waste annually; representing approximately one third of the nation's total solid waste stream (Rios, Chong, & Grau, 2015). Research in the USA shows that typical construction demolition waste is 40-50% concrete, 20-30% timber, with the remainder being primarily bricks, plaster wall sheeting, metals and plastics (Srour, Chong & Zhang, 2012).…”

The construction and demolition industry accounts for approximately one third of all material waste in the industrialised nations of the world. This material and energy waste can however be reduced through increased levels of material and component reuse. A strategy of design for disassembly has been well implemented in product design and manufacture, but the construction industry has failed to adopt such approaches, largely due to the more bespoke nature of architectural projects. This paper explores the technological options for material and component disassembly in buildings. The research projects utilises inductive reasoning to conduct a number of architectural case studies, observing the reoccurring patterns of design that have facilitated material disassembly, then proposes a model or taxonomy of recycling and reuse strategies. The case studies reveal a hierarchy of recycling potentials, each facilitated by different strategies of design for disassembly. This hierarchical taxonomy of recycling can be used to guide design decisions at the early stages of architectural projects; thus increasing the potential for material and component recovery, and reduce negative environmental impact at the future stage of building obsolescence. The paper concludes with design principles, linked to the taxonomy of reuse and recycling.
