Innovative Approaches To Sustainable Building Practices In Nigeria: Advancing Green Construction Through Local Materials And Technological Integration: A Case Study Of Abuja Municipal Area Council (Amac)
1. Introduction to Sustainable Building
Sustainable Building has become a central concept in modern construction due to increasing environmental concerns, rapid urbanization, and the urgent need for affordable housing. The construction industry is one of the largest consumers of natural resources and a major contributor to pollution and greenhouse gas emissions. Traditional construction practices rely heavily on energy-intensive materials such as concrete, steel, and fired bricks, which significantly impact the environment.
In response to these challenges, Sustainable Building promotes environmentally responsible practices that reduce resource consumption, minimize waste, and enhance the overall efficiency of buildings. It integrates environmental protection, economic feasibility, and social well-being into the design, construction, and operation of buildings.
2. Concept and Definition of Sustainable Building
