1.1 Background of Study
Sustainability in Architecture is a concept that is gaining a wide momentum. Several researchers define sustainability in Architecture in several ways. According to Ghani (2012), sustainable architecture involves a combination of aesthetic, environmental, social, political and moral values. It refers to the ability of a society, ecosystem or any such ongoing system, to continue functioning into the indefinite future (without being forced into decline through exhaustion of key resources. While Sassi (2006), sees it as a development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It involves addressing a wide spectrum of issues, sometimes, seemingly, conflicting ones. Acquiring a basic knowledge of these issues is the first step towards establishing or clarifying personal values and moving towards a more sustainable future (Sassi, 2006).
Benefits such as energy, water and operational cost savings, improved air quality, and increased productivity are drawing more attention to sustainable buildings (Nadel, 2006).The principles of sustainable design (economy of resources, life cycle design, and humane design) can provide a broad awareness of the environmental impact, both local and global, of architectural consumption (Kim,1998).
Shopping malls or shopping centres are 20th-century adaptation of the historical market place, with accommodation made for automobiles. A shopping centre is a collection of independent retail stores, services, and a parking area conceived, constructed, and maintained by a management firm as a unit. Shopping centres may also contain restaurants, banks, theatres, professional offices, service stations, and other establishments (Rouse, 1962).
