Abstract This study evaluates the impact of advanced energy-efficient technologies on sustainability in the Nigerian construction sector, with an emphasis on their influence on energy consumption, cost reduction, environmental benefits, and social impacts. Employing a quantitative research approach, data were collected through structured questionnaires distributed among 150 construction professionals across Nigeria, achieving an 82% response rate. The analysis included descriptive statistics, ANOVA, and regression analysis to assess the perceptions and impacts of energy-efficient technologies based on different professional roles within the construction industry. Findings indicated that energy-efficient technologies substantially reduce energy consumption and operational costs, with most respondents reporting significant savings. Environmental impacts were also positively noted, with substantial reductions in carbon emissions aligning with global sustainability objectives. However, the study identified a less pronounced recognition of the social benefits of these technologies, suggesting a potential area for increased advocacy and education. Significant differences in perceptions across job roles highlighted the need for role-specific educational programs to harmonize understanding and implementation practices. Advanced energy-efficient technologies are crucial for enhancing sustainability in the Nigerian construction sector. The study underscores the need for comprehensive educational and policy initiatives to fully leverage these technologies for economic, environmental, and social benefits
