The “green” status is established by different green rating mechanisms, among
which the LEED certification is the most popular system that is internationally
recognized and widely used globally. The United States Green Building Council
(USGBC) introduced LEED which stands for “Leadership in Energy and Environmental
Design”. According to USGBC to receive LEED certification for a building it must
achieve a prescribed set of requirements. The building will be evaluated and awarded
its status certification which functions to explain the project’s achievements of green
concepts through the life cycle.
