Abstract
The global prominence of the circular economy model is a notable sustainability trend. Within this model, the design stage plays a critical role as the foundation. The adoption of circular design strategies (CDS) has been gaining appreciable traction in the architecture, engineering, and construction industry in Europe and Asia. However, limited adoption has greeted these strategies in Sub-Saharan Africa, specifically, in the Nigerian built environment. This is due to the dearth of empirical studies on CDS adoption and implementation, especially at the building design firms’ level. Hence, this study evaluated the adoption of CDS by firms towards identifying pathways for their increased uptake in Nigeria. Providing empirical knowledge on the adoption of CDS can contribute towards reducing material extraction and consumption, and the global economy circularity index. Roger’s Diffusion of Innovation theory was used deployed as the study's conceptual framework. A pragmatic philosophical paradigm was adopted for the study. Convergent parallel mixed research method was deployed and concurrent triangulation approach facilitated the integration of results. Quantitative data were collected through a questionnaire survey from 216 firms which were analysed by applying descriptive and inferential statistical methods using Statistical Product and Service Solutions version 21. An interview guide and observation protocol were employed in collecting qualitative data from ten firms involved in the design of certified sustainable buildings (CSBs) and nine CSBs, respectively. The qualitative data were manually analysed through a content analysis involving In-vivo coding and themes’ identification. The findings indicated that the disposition of firms towards CDS adoption is dependent on improving value and expertise, effective stakeholder management, collaboration, policy, and the tendency for economic capacity. The firms exhibit a moderate level of CDS awareness. However, they have only adopted certain strategies related to slowing and narrowing resource loops to a high extent. The adoption of strategies related to closing-resource loop is very low. The study further revealed the factors that influence CDS adoption by firms to include awareness, benefits, firm’s disposition, barriers, firm’s profile, and communication channels. Internet-driven peer networking channels were found to be the most effective means of diffusing CDS knowledge. Finally, CSBs in the study area have adopted certain CDS associated with designing out waste and slowing-resource loops, while the CSBs are still deficient in adopting CDS associated with closing-resource loop. Firms need to look inwards into the alignment of their visions, culture, and process in ensuring they conform with new market demand and embrace changes where appropriate, especially, in environmental sustainability consciousness in their design processes. Additionally, the roles, responsibilities, and support of the government, academia, and the industry were identified in contributing towards achieving the set agenda. The findings indicated that the adoption of CDS in building developments directly contributes to the sustainable development goal 12 – responsible consumption and production. This study contributed to knowledge by identifying the key characteristics that dispose firms towards CDS adoption. Furthermore, the firms and CSBs have least adopted closing-resource loop strategies in design. Similarly, recommendations to practice, academia, and policies were suggested to enhance resource optimisation in the NBE through the uptake of the strategies by firms. Further studies can investigate appropriate circular business models and circular project management approaches applicable in Nigeria.
