The clamor for sustainable development and reduction of greenhouse gases led to the green concept which, in recent times, has gained significant momentum. To encourage the widespread development of green buildings, an understanding of the awareness, benefits, and hindrances for their adoption is necessary. This is relevant now that concerns over climate change have led to an increasing global demand for sustainability within the built environment. While the discourse is still rather muted in Nigeria, this study will contribute to the ongoing effort to raise public awareness regarding green building development and the potential benefits by evaluating the opinion of professionals regarding the subject matter. Structured questionnaires were distributed among five different professions in the built environment and information sourced includes the level/mode of awareness, benefits and bottleneck, and support for its development. The survey results showed that 43.48% of the professionals advocated for the development of green construction in Nigeria. The benefits and bottlenecks were ranked according to their perceived importance. The study recommends public enlightenment on green education, enforcement of mandatory training, formulation and implementation of policies directed towards green building acceptability. This will help promote and protect the built environment, and reduce health hazards posed by conventional development.

The introduction of intelligent devices in buildings has brought about tremendous changes into the construction industry. The use of automation is also gradually gaining interest from the stakeholders involved in the built environment. This paper presents the perception of property stakeholders (property valuers/real estate developers and service users) regarding the acceptability of smart buildings as a future built environment in Nigeria, using Benin City a case study. A total of 159 structured questionnaires were administered with 108 retrieved and valid for analysis. The information sourced from the respondents includes smart building awareness, the support for, drivers to, and limitations of its implementation, the willingness to develop smart buildings, and the willingness to pay proportionate rent to occupy smart properties. The findings showed that the poll of respondents for the property valuers and the real estate developers, as well as the service users, claimed to be aware of the concept, and they also support its development in the country. The drivers and limitations were ranked based on their perceived level of significance. This study recommends the promotion of awareness to accelerate its acceptance and implementation. This will help propagate the process of creating a smart city in developing nations such as Nigeria and prepare property valuers professionally for its management.
