The building sector is a major contributor to global resource consumption and waste generation. The circular economy (CE) concept offers a promising alternative to the traditional linear economy by promoting the reuse, remanufacture, repair, and recycling of materials and products. However, the adoption of CE in the building sector faces several barriers. This paper presents a systematic literature review utilising the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach, focusing on the barriers and enablers influencing the adoption of the CE concept in the building sector. Drawing from an analysis of numerous papers published between 2008 and 2023, we identified a high number of barriers and enablers that delay the integration of CE. The barriers were categorised into six categories: awareness, technical, economic and market, implementation, support/promotion, and social. The paper also discusses the interdependence of the identified barriers, using a co-occurrence matrix. The study findings indicate lack of CE regulations, fragment supply chain, and high upfront investment cost as major barriers to the implementation of CE in the building sector. Based on the study results, stringent governance and legislation, financial incentives, and the development of technology and innovation for circular building tools are critical factors for the successful implementation of CE principles. The results of this study provide a comprehensive overview of the feasibility to CE adoption in the building sector, which could also help to develop strategies to accelerate the transition to an integrated CE.

The building industry is one of the largest consumers of materials resources and significant contributors to global waste. Applying core principles of circular economy (CE) could significantly help the environment by reducing waste and decreasing the life cycle cost of buildings. Several strategies to implement the concept of CE in buildings include design for deconstruction, adaptability, and flexibility. However, implementing these design strategies could face constraints. In this study, we identified 22 barriers related to the adoption of CE in buildings, as reported in the literature. We discussed the role of Building Information Modeling (BIM) in overcoming those barriers. This paper demonstrates how BIM can facilitate the implementation of CE principles while providing critical insights into the life cycle costs of circular buildings. We identified 14 ways to use BIM to foster the implementation of a circular economy approach. To achieve these objectives, we have undertaken a thorough review of recent publications that explore CE design strategies, Life Cycle Costing in the circular construction of buildings, and BIM developments in the building industry. This literature review is based on 88 articles covering BIM’s role in enhancing the management of a building’s end-of-life while reducing the life cycle cost in the circular construction of buildings.

The adoption of circular economy (CE) holds significant potential to mitigate the challenges posed by the conventional linear economic model. The building sector in Saudi Arabia continues experiencing rapid growth, often marked by a consistent annual rise in the number of projects. The incorporation of CE principles into this expansion presents opportunities to optimize resource utilization, minimize waste generation, and enhance overall environmental sustainability. This study explores the current levels of awareness, perception, and implementation of CE principles among local building sector stakeholders and assesses the potential for CE expansion in the region. Additionally, it seeks to rank the identified barriers and enablers while exploring the interconnected relationships between such barriers. A literature review was conducted to explore the CE barriers and enablers. This was followed by an online survey which was conducted amongst 139 respondents from diverse stakeholder groups. A relative importance index (RII) was employed to rank the barriers and enablers, and the findings were subjected to statistical analysis using the Statistical Package for Social Sciences (SPSS). The outcomes of this study highlight a significant lack of awareness regarding CE principles among stakeholders, with a very low implementation rate. To break this inertia and encourage the adoption of CE practices, this study suggests the need for CE- supportive policy and legislation, and the provision of financial incentives.

The concept of circular economy (CE) has emerged as an effective strategy for addressing resource depletion, waste generation, and environmental challenges, offering a promising path towards a more sustainable future. In the building sector, adopting CE principles can significantly mitigate environmental impacts, minimize lifecycle costs, and promote sustainability throughout a building’s lifecycle. Using a mixed-method approach via a pre-interview questionnaire and semi-structured interviews with 10 sustainability experts, this study analyses the significance of 15 CE strategies in building construction projects, assessing their importance and ranking their potential for adoption. Furthermore, this study evaluates the feasibility of applying CE principles to different building types, including storage, industrial, commercial, residential, business, and healthcare facilities. The role of lifecycle stages including initiation and planning, design, procurement, construction, operation and maintenance, and end of life is examined to identify phases with the highest potential for successfully embracing CE principles. The role of stakeholders in driving change is also analyzed. The outcomes of this study reveal that the most feasible strategies include the use of renewable energy, design for durability and longevity, prefabrication, and offsite construction. The study findings indicate that storage, industrial, and business (office) buildings are the most feasible for CE application, while the initiation and planning and design stages are identified as critical phases for embracing CE adoption. Owners and designers emerge as the stakeholders with the greatest influence on CE implementation. The results of this study provide a comprehensive overview of the feasibility of CE adoption in the building sector. These findings offer valuable insights that can inform the development of targeted strategies to support the effective adoption of CE principles.

The construction industry continues to play a significant role in the economic development of most nations in the world. However, the construction sector still follows the ‘linear’ ‘take–make–dispose’ industrial model that, having benefited development, plays a major factor in the depletion of resources, environmental deterioration, and the generation of waste and pollution. In this regard, the adoption of a circular economy (CE) presents a compelling opportunity to address the challenges derived from the traditional linear economic model. This study attempts to scrutinise the critical success factors (CSFs) for implementing a CE via a mixed-method approach that combines both focus groups and an online survey. The adopted approach ensures a comprehensive identification and prioritisation of CSFs for implementing CE principles in building construction projects. The focus groups consisted of 20 key stakeholders drawn from prominent construction firms which included clients, consultants, contractors and designers. The outcomes from these focused groups led to the dentification of 43 CSFs, later categorised across different dimensions. Subsequently, an online survey was conducted to establish a priority list of the identified CSFs, using responses from 82 stakeholders to rate their level of importance. The top five significant CSFs include ensuring the use of standardised and warranted secondary materials, maintaining cost equivalence between a CE and linear approach, maintenance and operation cost minimisation, assessment of life cycle cost (LCC), and the enforcement of robust government regulations and policies that prioritise a CE. The Relative Importance Index (RII) was used to rank the identified CSFs following results obtained using the Statistical Package for Social Sciences (SPSS 27) and Excel for Microsoft 365. The findings of this study can inform the creation of decision support systems that could progress a CE across the construction project life cycle.

Several challenges are associated with implementing Circular Economy (CE) in buildings. These include legal, technical, social, behavioural, and economic barriers. As a result of these challenges, Building Information Modeling (BIM) has emerged as a tool to address them, supporting the development of digital models for sustainable end-of-life and offering material passports for efficient recovery of materials. This paper aims to review recent publications on the topic to explore strategies, material selection criteria and the role of circular components at various stages of building construction. This literature review is based on a review of 50 articles that contributes to the understanding of how BIM can enhance Life Cycle Costing (LCC) in the circular construction of buildings. This review identifies the barriers to implementing CE in buildings by examining recent publications in CE and highlights BIM potential to address these challenges. In this paper, the role of BIM is discussed in relation to sustainable design, material recovery, and components selection for buildings in circular construction. In addition, the review examines whether BIM can be used in circular construction to reduce LCC and promote sustainability. In constructing buildings in circular construction, BIM can be instrumental in enabling decision-makers to conduct comprehensive economic studies, leading to more holistic decision-making.
