\ud \ud Green building (GB) has been viewed as an effective means to implement environmental, economic, and social sustainability in the construction industry. For the adoption of GB technologies (GBTs) to continue to succeed and gain popularity, a better understanding of the key issues influencing its progress is crucial. While numerous studies have examined the issues influencing green innovations adoption in general, few have specifically done so in the context of GBTs. This study aims to investigate the underpinnings of GBTs adoption in the following areas: (1) the critical barriers inhibiting the adoption of GBTs, (2) major drivers for adopting GBTs, and (3) important strategies to promote GBTs adoption. To achieve these objectives, a questionnaire survey was carried out with 33 GB experts from the United States. Ranking analysis was used to identify the significant issues associated with GBTs adoption. Resistance to change, a lack of knowledge and awareness, and higher cost have been the most critical barriers. The major drivers for adopting GBTs are greater energy- and water-efficiency, and company image and reputation. The analysis results also indicate that the most important strategies to promote the adoption of GBTs are financial and further market-based incentives, availability of better information on cost and benefits of GBTs, and green labelling and information dissemination. The findings provide a valuable reference for industry practitioners and researchers to deepen their understanding of the major issues that influence GB decision-making, and for policy makers aiming at promoting the adoption of GBTs in the construction industry to develop suitable policies and incentives. This study contributes to expanding the body of knowledge about the influences that hinder and those that foster GBTs implementation.\ud \ud Keywords\ud \ud Green building technologies; Barriers; Drivers; Promotion strategies; United State

As a response to mitigate various negative environmental effects of the construction industry, recent years have witnessed a growing interest in green building technologies (GBTs) adoption and development. Consequently, many studies have been conducted on the forces driving the GBTs adoption in different countries. However, there have been few studies identifying the driving forces (DFs) for GBTs adoption in developing countries such as Ghana. This study aims to identify the major DFs for GBTs adoption within the developing country of Ghana. To achieve the objective, 21 DFs were identified from a comprehensive literature review. Through a questionnaire survey with 43 professionals with green building experience, the results first indicated that “setting a standard for future design and construction”, “greater energy efficiency”, “improved occupants' health and well-being”, “non-renewable resources conservation”, and “reduced whole lifecycle costs” were the top five forces driving the GBTs adoption. Further comparative analysis showed that the topmost rank of “setting a standard for future design and construction” is unique for GBTs adoption in only the developing country of Ghana, not in the developed country of the US. Additionally, factor analysis revealed that the underlying forces for the 16 significant DFs were environment-related, company-related, economy and health-related, cost and energy-related, and industry-related forces. This study improves understanding of the major DFs for GBTs adoption, providing a valuable reference for practitioners and policy makers to promote the wider adoption of GBTs. Future study will investigate the interrelationships between the significant DFs and their impacts on the GBTs adoption process. Future work is also required to employ a larger sample and investigate in greater detail the differences between the GBTs adoption DFs in Ghana and many other specific countries.Department of Building and Real Estat
