LEED certification

Origin and objective of the certification

LEED certification is an international standard and evaluation system developed by the U.S. Green Building Council in the late 1990s to encourage the development of buildings based on sustainable and highly efficient criteria. LEED® is a flexible system that can be applied to any type of building, both in the tertiary and residential areas.

In addition, the certification is applicable to buildings and their shells as well as to independent spaces within them.

LEED certification groups the criteria into 5 main areas.

Fields of action


in construction materials and resources.

Materials and resources

employees who are environmentally friendly.

Energy efficiency

since the construction, counting also with the least atmospheric impact, this is the value that scores more, looking for the saving, beneficial for both the environment and for those who use the building.

Efficiency and use of water

both during construction and when the building is in use for the purpose it was originally planned (reuse of water and prevention of leaks).

Indoor environment quality

that allows the optimal habitability of it, without having to resort to more energy than necessary to heat or cool it.

Innovation in the design process,

giving prominence to all eco-efficient resources.
