Renewable energy sources and technologies in commercial buildings: Understanding the Nigerian experience

Purpose: The purpose of this paper is to explore the perceptions and experiences of building practitioners in the adoption of renewable energy (RE) in commercial buildings in Nigeria. Design/methodology/approach: A qualitative methodology was used guided by the principles of the Grounded Theory Method (GTM). Data were collected using in-depth semi-structured interviews with a purposive sample of five industry practitioners. Findings: Five distinct factors emerged, namely, being compliant, change in mindset, normalising, being autonomous and identity. The research revealed the significance of contextual (cultural) peculiarities and the role identity plays in informing RE adoption. The findings substantiate the significance of RE adoption in the future practice of building practitioners and in ensuring environmental stability within the Sub-Saharan Africa (SSA) context. Research limitations/implications: The study focuses on commercial office buildings and attempts to provide contextual grounding to inform theory generation as part of a wider study. Originality/value: This research contributes methodologically and empirically by providing grounded insight into the adoption of RE in commercial buildings. Thereby, enabling a much greater understanding of the issues associated with enhanced promotion and adoption by professionals and stakeholders, which can inform policy interventions. Furthermore, it will benefit further research within the SSA context and provide valuable lessons associated with adopting GTM in construction research.
