A structural equation model of stakeholder roles in the implementation of green construction strategies in the Indian construction industry

Abstract

The construction industry is one of the leading contributors to greenhouse gas emissions into the atmosphere. Hence, the construction industry needs to start implementing green construction practices. However, various barriers are faced by the stakeholders of the industry which are restricting the shift to green construction. The 12 most frequently mentioned factors in the literature were used to prepare a questionnaire instrument. Responses were received from various stakeholders of the industry on the importance of the mentioned barriers on a five-point Likert scale. A structural equation model was developed attributing the 12 barriers to the 4 responsible stakeholders like Government& Statutory bodies, the Construction industry, Researchers & Academia, Consumers & clients through detailed observation, and experts’ opinions. A confirmatory factor analysis was performed on the model using the SPSS AMOS package, to validate the goodness of fit of the developed model. ‘Limited professionals with proficiency in green building techniques and strategies’, ‘Lack of awareness of the need for green construction’ and ‘Financial & economic feasibility issues’ were found to be the three most influential factors. The survey data was proved reliable through Bartlett’s test of sphericity, Kaiser-Meyer-Olkin test and other goodness of fit tests.
