The adoption of green building practices in construction projects in Qatar: a preliminary study

It is widely known that carbon dioxide emissions and climate change are among the most critical global challenges. These issues were worsened partly by the continuous adoption of traditional non-green behaviors and practices in the construction sector. As both environmental and health-related practices continue to worsen, practitioners, researchers and government think tanks are taking a major shift to promote green building practices (GBP). The purpose of this paper is to examine and investigate the effects of several environment-related variables such as sustainable government support, environmental concern and green engagement in the adoption of GBP.

The model of the study was developed based on the integration of the theory of planned behavior (TPB), value-belief-norm and cognition-affective behavior (CAB). The instrument used to capture these constructs was adapted from existing validated instruments. The data were collected from Qatar-based consultant and contractor engineers. Of the 877 questionnaires distributed, 378 were completed which yields a response rate of 43 percent. The collected data were analyzed by employing the PLS-SEM approach. First, the measurement model was examined to confirm the validity and reliability of the measures. Next, the structural model was analyzed to test the hypotheses of the study.

The results of the study showed that environment-related variables such as green engagement, sustainable government support and environmental concern have strong effects on GBP along with other TPB variables, namely, subjective norms and attitudes.

Although the objectives of the study were achieved, there are still some limitations. First, this study yields a deemed suitable response rate. Second, since this research focused solely on the view of the contractors and consultants of the country’s engineering sector, it may have narrowed down the real scenario.

Besides the government providing awareness campaigns on the importance of GBP in reducing pollution, the government may also set some regulations to be followed by construction companies to reduce the negative impacts on the environment and regulations that could motivate the decision makers to increase the green construction projects and practices. In addition, the engineers still need some supports from green building authorities and government to motivate them toward GBP. Some incentives that could be offered by the government are financial allowances, funding and reduced governmental fees.

This study has a great theoretical value since it extended the TPB by incorporating some important environment-related variables to explain the adoption of GBP. In addition, from the practical perspective, this study provides useful insights for the practitioners and policy makers who are concerned about designing and planning environment-friendly strategies in the sector of construction.
