The concept of sustainability has been defined variously by many writers. However, the definition given by the World Commission on Environment and Development (WCED) has been received with greater enthusiasm – “Sustainability represents forms of progress that meet the needs of the present without compromising the ability of future generations to meet their needs”. This definition meets most of the requirements of modern writers whose definitional demands might be very difficult to satisfy. The need to re-conceptualize the material environment so that the rate at which resources are consumed at present would be less than the rate at which replacement takes place is all the more important now. The process of production and the process of consumption in the economy of a country are determined by the amount of innovation and the aggregation of the five basic sustainability principles as enunciated by Buckminster Fuller (Dresner, 2002, p.37). They are the material domain, the economic domain, the domain of life, the social domain and the spiritual domain. According to Fulter, the material domain is the pivotal principle essential for regulating the movement of materials and energy that support the very essence of life. The economic domain serves as a principal mechanism to manage wealth. The domain of life provides the underlying essence for apt conduct in the biosphere. The social domain lays the foundation for societal interrelations. Finally, the spiritual domain serves as the basis for the necessary orientation in attitudes thus facilitating the formation of a universal code of moral principles by which the individual abides and acts.
Thus in addition to the whole systemic process of principles for sustainability and its communication to the community, the project management aspect of sustainability critically looks at the designing, regulation and strategic transformational phases of it to achieve what’s known as the environmental compatibility. Sustainability evaluation involves metrics or such quantifiable parameters to portray significant values inherent in the process though qualitative assessments can be of equal significance.
