This study explores managerial requirements for optimizing energy-efficient buildings (EEBs) in Nigeria, focusing on policy effectiveness, awareness, and adoption barriers. Quantitative research approach was adopted through online questionnaires, which yielded 154 responses which were analyzed with descriptive analysis. The respondents are industrial professionals like architects, building technologists, engineers, estate surveyors, consultants, construction Managers. Our findings indicate that while new and updated policies demonstrate continuous improvement in the energy efficiency sector, implementation varies across different climatic zones. Key barriers to EEB adoption include limited access to financing, sustainability promotion, and occupant well-being concerns. Conversely, impactful awareness, research and development, and public-private partnerships are identified as crucial promoters of EEBs. This study provides insights into the Nigerian energy efficiency sector, highlighting areas for policy refinement and strategic intervention. The research contributes to developing effective managerial strategies for promoting EEBs in Nigeria and similar contexts.
