Factors influencing adoption of green buildings in Tanzania: a qualitative case study

Abstract

PurposeGreen buildings have proven to be essential contributors to the sustainability of buildings in the construction industry. However, in developing economies, the rate of green building adoption is slow. Moreover, the factors linked to a relatively slow adoption rarely feature in the literature. This study seeks to bridge the gap by first exploring factors influencing the adoption of green buildings. Second, analysing strategies and preferences determining the adoption of green building principles and lastly, exploring case-based opportunities for their adoption in Tanzania.Design/methodology/approachSemi-structured interviews were conducted to collect qualitative data from twelve key informants. The qualitative data were analysed using content analysis.FindingsThe findings indicate that the most influential factors in green building adoption are related to key organizational decisions. Moreover, social and environmental factors are more related to green building adoption than economic factors. In addition, energy and water efficiency are the most commonly adopted sustainability features, while certified materials, recycling and reusing are rarely implemented.Practical implicationsSince green building adoption is still in its infancy, this study informs policymakers, professional bodies, developers, and researchers of the empirically supported factors for green building adoption. The conclusions can be amplified within the sustainability movement.Originality/valueThis study provides an in-depth understanding of the precursors of green building adoption, which is increasingly becoming a paradigm shift in the construction sector. The study is the first to present an in-depth analysis of the real-life factors influencing the adoption of green buildings in Tanzania.
