LEED focuses on green construction and the ecological design of a building, but the certification does not have a qualification after the project is completed. Tenants in a LEED-certified building may be consuming more energy or water than tenants in other buildings, despite design efforts to reduce use. A building built taking into account ecological standards can then receive green building certification. A space can be green if it isn't certified, but the certification of green buildings has tangible benefits.
One of the most commonly used green building rating systems for certification is LEED. LEED stands for Leadership in Energy and Environmental Design. It is an internationally recognized green building rating system that verifies that construction uses environmentally sustainable strategies. LEED is a holistic system that does not simply focus on one element of a building, such as energy, water or health, but rather analyzes the big picture taking into account all the critical elements that work together to create the best possible building.
LEED is for all types of buildings and all phases of construction, including new construction, interior conditioning, operations and maintenance, the core and the housing. Green building practices continue to develop and are becoming more popular as concerns about sustainability increase.
