EFFECT OF TECHNOLOGICAL INNOVATION AND BUILDING DESIGN CONSIDERATION ON SUSTAINABLE URBANISM IN SELECTED REAL ESTATES, LAGOS STATE NIGERIA

Abstract

Creating cities that are economically, environmentally and socially sustainable will be one of the biggest tasks of this century in the face of current fast urbanization, environmental degradation and natural resource depletion. In a bid to arrest this situation, technological innovations in the building construction industry that can help preserve the ecosystem through efficient energy, water and waste management has been taunted as way out. Based on this assertion, this study seeks to assess the role of technological innovation and building design consideration on sustainable urbanism in Selected Real Estates, Lagos State, Nigeria. The study adopts a survey research technique which involves the use of well-structured questionnaire to elicit information from the respondents. Simple random sampling technique was used to distribute 220 copies of questionnaire among the respondents who are residence of three selected real estates namely, County Estate (Agege), Unity Estate (Ikorodu) and Arowojobe Estate (Victoria Island) selected across the three senatorial districts in Lagos State Nigeria. 183 copies of questionnaire were eventually analysed with SmartPLS3.0 and SPSS version 25 coding data after cleaning. The mean scores on the level of adoption of sustainable building design reveal that indoor environmental quality (3.95), water conservation (3.32) and optimization of site potential (3.16) were unanimously agreed by the respondents to be among the most considered by building designers in ensuring sustenance and exploitation of natural resources. Furthermore, descriptive statistics also shows that high initial cost of building a sustainable home (4.57), Reluctance to leave conventional buildings adapted to for sustainable building (3.78) and level of income (3.77) are the key factors affecting the adoption of sustainable building design in the study area. A statistically insignificant P-values of 0.216 and 0.91 95% significance level for energy conservation and site optimization potential respectively indicates that energy conservation and optimization of site potential aspects in building design considerations have not been critically looked into by designers in ensuring a healthy built environment for man and the ecosystem. However collaborative design approach has the highest contribution with beta value 岫�岻 of 0.307 with P-value 0.02. Findings also reveal that technological innovation no mediation between the endogenous and exogenous variables. First hypothesis result shows that there is significant difference between sustainable building design and sustainable urbanism at P-value (0.000), less than 0.05. Result of second hypothesis as it that there is no significant difference between role of technological innovation adoption on the sustainable building design and sustainable urbanism in the study area. Hence the study concluded that technological innovation in building design and construction has not been exploited thereby giving rise to natural depletion and environmental degradation in the study area event. The study therefore recommends that sustainable building practices should be considered by building control agency as a criterion to acquire building construction permit. v
