Abstract
With a growing priority on resolving environmental issues and managing resources more effectively in line with Sustainable Development Goal 12, this research aims to assess solutions to minimize resource consumption in the Ghanaian construction sector. In the Ghanaian cities of Accra and Kumasi, questionnaires were utilized to solicit responses from construction stakeholders. Mean score ranking was used to rank these techniques. A reliability analysis using Cronbach's alpha coefficient found a high level of internal consistency. A high level of agreement was found after testing using Kendall's concordance. A one-sample t-test was also employed to examine the relative importance of the variables. Properties should be built to be disassembled; sections of existing building structures should be reused; prefabricated components should be utilized for on-site assembly; demolition components should be re-used or recycled, and existing buildings should be renovated to prevent destruction. This research is valuable because it adds to a checklist of measures for minimizing the effect of resource consumption in the Ghanaian construction sector, as well as to the achievement of the SDG goal. Project managers, architects, engineers, subcontractors, and other key stakeholders are encouraged to use innovative approaches to decrease resource consumption.
