Green building (GB) encompasses a holistic range of environmentally, socially, and economically conscious features addressing sustainability within building design, including energy efficiency, technological innovations, and materials recycling. Within the realm of housing, these integral green attributes synergistically contribute to the creation of living spaces that are not only environmentally friendly but also energy-efficient, health-enhancing, and comfortable. This comprehensive study investigates the paramount aspect of green building through the perspectives of both the general public and experts, assessing their acceptance and support for green building practices in Nigeria, a strategic choice due to its pivotal role within the Green Building Council in Africa, representing one of seven nations. Employing Factor Analysis and the Relative Importance Index, our rigorous analysis scrutinizes residential developments to pinpoint the most influential green building attribute. Our extensive questionnaire, distributed within the bustling metropolis of Kano, Nigeria, selected for its substantial population size in northern Nigeria and its status as the country's second most populous state, unveils a compelling revelation: social attributes wield the most profound influence over the successful implementation of green building practices, emphasizing their central role in sustainable development initiatives.
