LEED stands for Leadership in Energy and Environmental Design and is among the leading green building certification programs. Developed under the guidance of U.S Green Building Council (USGBC), it lays out a framework for green development — rating system for design, construction, operation and maintenance of green (eco-friendly) buildings.

The main agenda behind LEED certification is to demonstrate their energy efficient and environmentally suitable management of elements within construction — design credits and construction credits.
