Establishing initial hypothetical pls-sem for the challenges of converting existing office buildings to green buildings in Sri Lanka

Abstract

Sri Lanka is progressively moving towards sustainability concepts to achieve a circular economy and sustainable development goals. The challenges to converting existing offices to green buildings in Sri Lanka assed in 50 low-rise office buildings in Colombo through 150 decision-makers. There were 25 challenges identified initially from a systematic literature review, and the challenges were further reduced to four main components in the PCA to reduce complexity. The initial hypothetical PLS-SEM model was established to identify the main challenges and the others that fall under it. The four main challenges can be categorised into; Industry and Technology Environment (ITE), Corporate issues (CI), Government Interventions (GI), and Stakeholder Awareness (SA).
