Determinant Criteria for Green Procurement Implementation Strategies (GPIS) in Building Retrofitting Works in Sarawak

Green procurement plays a crucial role in fostering sustainability in the construction industry by addressing the lifecycle impacts of goods and services. In Sarawak, where lies the architectural landscape includes numerous heritage structures, building retrofitting works aligns with the Sarawak Post COVID-19 Development Strategy (PCDS) 2030, emphasizing sustainable development through circular economy and cultural preservation. However, the implementation of green procurement in retrofitting works faces challenges due to inadequate guidelines, a fragmented supply chain, and a short-term focus that overlooks long-term benefits. To address these issues, this study has adopted a bibliographic review technique utilizing various literature compiled from leading databases including Scopus, Web of Science and Google Scholar. It aims to identify the criteria as implementation strategies in adopting green procurement for retrofitting projects in Sarawak. The findings indicated that there are ten (10) strategies (independent variables) that can be considered in implementing green procurement for building retrofitting works (dependent variables). The criteria are identified as Carbon Footprint Analysis (CF), Green Purchasing (GP), Lifecycle Considerations (LC), Reduced Operational Costs (RO) and Stakeholder Capability (SC). The discussion summarized its relevance to the building retrofitting context with a final construct of conceptual framework relating both IVs and DVs. The findings suggest that stakeholders, policymakers, and practitioners need to recognize these main factors to achieve better sustainability and efficiency in building retrofitting works.
