Abstract: The introductory section of the paper starts off by discussing the concept of sustainability and the current building ratings systems applicable in varied attempts to classify buildings and their various aspects of sustainable building operations to qualify to be labelled as green buildings. A sustainable building maximises operational efficiency while minimizing environmental impact. It goes on to explain the various fundamental measures that are critical to incorporate in sustainable real estate development including the Leadership in Energy and Environmental Design (LEED) launched in March 2000. The critical features of a sustainable building are taken to include the following; low operational energy,low carbon emission,use of renewable resources,little or preferably no waste,low maintenance,high durability and the use of appropriate technology.
