Energy conservation and improving efficiency remain top issues facing construction projects today. Studies on energy-efficient technologies are scarce in construction sector, and this area needs to be focused. Energy-efficient technologies have been proved important tools to manage cost and improve project efficiency. Despite the fact that energy-efficient technologies have been embraced by developed countries, its adoption and usage are still at an infancy state in developing countries due to different obstacles. Due to energy shortage and crises, promotional strategies need to be established to facilitate the integration of energy-efficient technologies in construction projects of developing countries. Therefore, the current study empirically aims to analyze promotional strategies for energy-efficient technologies adoption in developing countries by considering the Pakistani context. Initially, major promotional strategies were extracted from earlier studies and then filtered through the fuzzy Delphi method. Later, a structure analysis was performed to prioritize essential strategies by utilizing mixed methodology of interpretive structural modeling and ‘Matriced’ Impacts Croise´s Multiplication Applique´e a UN Classement’. The results found that ‘Government tax incentives and energy-efficient technologies-related financial schemes’, ‘organizing international conferences and workshops to support energy-efficient technologies adoptions’, ‘learning from energy policies of developed countries’, ‘government regulations and standards’ are the most important promotion strategies and could expedite energy-efficient technologies adoption in construction projects of Pakistan. Theoretically, this study contributes to construction sector literature by enlisting major promotional and practically, this study could be useful for Governments and policymakers to integrate these strategies into long-term planning to promote energy-efficient technologies in construction projects.
