Investigating Critical Barriers of Green Building Technologies (GBTs) Adoption in the Sri Lankan Construction Industry

Abstract

This research investigates the critical barriers to the adoption of Green Building Technologies (GBTs) in the Sri Lankan construction industry. Despite the global shift towards sustainable construction practices, Sri Lanka has been slow to embrace GBTs due to various challenges. Through a comprehensive literature review and a survey of 50 industry professionals, this study identifies 14 significant barriers, including high initial costs, economic uncertainties, and lack of supportive government policies. The findings highlight the predominance of economic and political barriers, emphasizing the need for targeted strategies such as financial incentives, policy reforms, and capacity-building initiatives. The study concludes that overcoming these barriers is essential for advancing sustainable construction practices in Sri Lanka and promoting long-term environmental sustainability.
