Leed

LEADERSHIP IN ENERGY AND ENVIRONMENTAL DESIGN

Leed, acronym for Leadership in Energy and Environmental Design, is an evaluation of the energy and environmental performance of the buildings aiming to the promotion and spread of the so called “green” buildings that are characterized by high standard of energetic and environmental sustainability. The Leed system was born in America in 1933, promoted by the US Green Building Council (Usgbc), a non-profit organization of more than 11 thousand members. Being part of the LEED scheme allows to obtain a certification of the buildings that have achieved the required levels of energy and environmental performance and in compliance with specific eco-friendly requirements.

The building undergoing certification must meet all the mandatory requirements, while the credits are awarded based on the level reached by the requirements considered, assessed according to established criteria.

The Leed structure includes seven areas:

  • site sustainability

    MAX. 26 CREDITS

    The building and its surroundings: limiting the impact of construction activities, controlling the flow of rainwater, using constructive techniques that respect the balance of the ecosystem, reducing the "heat island" effect, reducing light pollution, etc.

  • water management

    MAX. 10 CREDITS

    Use, management and disposal of water: reduce drinking water consumption, reduce the volume of sewage discharges, reuse rainwater.

  • energy and atmosphere

    MAX. 35 CREDITS

    Improvement and control of energy performances, use of energy from renewable or alternative sources.

  • material and resources

    MAX. 14 CREDITS

    Selection of materials: increasing the use of sustainable materials, reducing waste for disposal (during construction and demolition), reducing the environmental impact due to transportation.

  • internal quality

    MAX. 15 CREDITS

    Quality of the internal environment: healthiness, safety, comfort, energy consumption, ventilation, natural lighting, control of pollutants in the air.

  • design innovation

    MAX. 6 CREDITS

    Innovating techniques and sustainability in construction.

  • regional priorities

    MAX. 4 CREDITS

    Increase awareness upon the characteristics of the environmental areas of the location where the works are carried out.

The system is based on the assignment of points for each of the requirements characterizing the sustainability of the building, from the sum of those credits derives the level of certification obtained:
