PurposeDespite the global shift toward smart building features and technologies, the level of awareness among stakeholders in Nigeria’s construction sector remains unclear, limiting engagement with these innovations. This study examines the awareness of smart building features and technologies, providing insights to address knowledge gaps and improve understanding within the sector.Design/methodology/approachThis study adopted the quantitative research approach, using a questionnaire survey to obtain data from construction stakeholders that were purposively selected in Lagos State and Abuja, Nigeria. The collected data were analyzed using various statistical tools such as frequencies, percentiles, mean item scores, standard deviation and the Mann–Whitney U test.FindingsFrom the result of the analysis, the study concluded that the most cognizant smart building features and technology were security doors, escalators and lifts, solar panels and energy-saving equipment, fire alarms, heating, ventilation, air and conditioning.Practical implicationsThis study provides insights into the awareness of smart building features and technologies among Nigerian construction stakeholders, bridging theory and practice. It informs policy development, enhances professional knowledge and promotes educational initiatives. Its findings support sustainable construction efforts, potentially improving societal attitudes and quality of life.Originality/valueThis study uniquely explores the level of awareness of smart building features and technologies among clients and professionals in Nigeria’s construction sector. Identifying existing knowledge gaps provides critical insights that can guide efforts to enhance understanding and foster deeper engagement with these innovations.
