IMPER ITALIA belongs to the Green Building Council of Italy (GBC Italy), an association whose aims are to promote the spread of a culture of sustainable building, raise awareness among the public and institutions of the impact that design and construction methods have on the quality of life, and provide clear guidelines for design professionals, builders and developers.
GBC Italy is in charge of applying and developing the LEED (Leadership in Energy and Environmental Design) rating system in Italy. This system is based on sustainable building parameters developed in the United States and now applied in 41 countries around the world to encourage "green" construction practices.
The LEED certification program applied in over 100 countries worldwide was developed by the U.S. Green Building Council (USGBC), a not-for-profit association that promotes and sustains a whole-building approach to sustainability, providing recognition performance in key areas of human and environmental health.
The USGBC’s LEED standards have been adapted for Italy by the GBC Italy, which has created a local version indicating requirements for constructing buildings that are environmentally sustainable from both the energy standpoint and as regards the consumption of all the environmental resources involved in the construction process.
The non-profit US Green Building Council organization that sets and promotes LEED standards was established in 1993 and now has over twenty thousand members. In addition to its “technical” role, the USGBC’s mission is to inform, raise awareness and orient the public towards ecologically sustainable construction. GBC Italy, thanks to a structure which is very similar to its US counterpart and its excellent relationships with the latter, carries out the same functions on the national level through its 300-plus associates. LEED is a voluntary, consensus-based rating system for designing, constructing and managing high performance sustainable buildings that is enjoying increasing international popularity. It can be applied to any type of construction and promotes a whole-building approach to design.
LEED is a flexible, wide-ranging program with different versions for new constructions (Building Design & Construction – Schools – Core & Shell), existing buildings (EBOM, Existing Buildings) and individual houses (LEED for Homes), while maintaining a consistent approach for all types.
