The aim of this study was to employ Green Architecture as a panacea to the environmental effects of Architectural development in Nigeria. There are a lot of environmental effects posed by the built environment, this may have arose as a result of Architectural development channeled towards a radical development of an artificial environment. Architectural development will be catastrophic without setting a balance between the natural environment and built or artificial environment. As much as Architectural d3evelopment is essential to foster progress so also due consideration must be given to the Adaptation and Sustenance of the built environment. Green Architecture which was carved out from post-modernism fulfills best practices in environment development. This is true because Green Architecture is the most tangible reflection of a profound change in ecological patterns that has occurred over the last one hundred years, but the most common problem in Architectural development are the environmental effects engulfed in its adaptability and sustainability, most especially in the tropical regions like Nigeria considering the inadequacy of Electricity, therefore, the promotion of adaptability and sustainability in Architectural practice is of great importance which is the central aim of this study. The researcher’s primary source or method of data collection was based on Analytic studies using descriptive method of data analysis to evaluate the draw backs of existing Architectural practice. Studies has shown that most of these practice failed to anchor its developmental strives to adaptability and sustainability most especially in developing countries due to so many deficiencies. The Natural elements of the environment has not been fully harnessed in maintaining ecological balance in the environment. To accomplish this development, Architectural development must benefit from an integrated design approach that focuses on meeting a list of objectives through a tropical design that offers owners and users an increased working satisfaction and productivity, improved health, greater flexibility, enhanced energy and environmental performance at little or no cost.
