LEED® is a voluntary certification program that can be applied to any type of building (both commercial and residential) and covers the entire life cycle of the building itself, from design to construction.
LEED promotes a sustainability-oriented approach, recognizing the performance of buildings in key sectors, such as energy and water savings, the reduction of CO2 emissions, the improvement of the ecological quality of the interiors, the materials and resources used, the project and the site selection.
Developed by U.S. Green Building Council (USGBC), the system is based on the attribution of “credits” for each requirement.
