Factors driving consumer adoption of smart and green building materials: the role of civil engineers and architects

Abstract

This study aims to investigate the role of civil engineers and architects in driving consumer adoption of smart and green building materials in Bengaluru, India. A mixed-method approach is employed, including quantitative surveys of 350 consumers and qualitative interviews with 30 civil engineers and architects. The data are analyzed using descriptive, Confirmatory Factor Analysis (CFA), Structural Equation Modeling (SEM), and thematic analysis. Income acts as a moderating variable influencing the consumers in adoption. Civil engineers and architects use innovative marketing strategies, public education campaigns, and consumer involvement in decision-making. However, various barriers such as initial costs, limited availability, lack of expertise, and complex regulations prevent widespread adoption. The qualitative analysis highlighted the environmental benefit as the most relevant factor, increasing awareness and providing education as the most powerful strategy. Conversely, the lack of a uniform rating system and certification system is the most critical challenge affecting the adoption of these materials from a consumer behaviour perspective. Therefore, the study recommended incentivising green building materials, promote knowledge via professional development, and expedite regulatory procedures to encourage widespread use. The study uses civil engineers and architects as consumer acceptability influencers to help policymakers create a smart and green building material consumption roadmap.
