What is LEED?

Leadership in Energy and Environmental Design (LEED) is an American building environmental rating system. Recognized in 132 countries, it is the most well-known sustainable building certification system in the world, with the most certified buildings to its credit. It is based on the holistic impact of a building, from impacts on human health to impacts on the environment..

What types of certification are possible?

LEED is applicable to new construction, renovations, existing structures, as well as specific parts of the building such as the envelope and structure or interior design. The LEED rating system can also be used to assess the performance of a neighborhood or community.

Among these systems, LEED offers several guides and scoring grids specific to the activities and functionalities of building types. There are also specific systems suitable for hotels, hospitals, residential projects, offices, schools, logistics centers, data centers and retail. For these types of buildings, LEED has developed specific guides applied to their functional needs. For example, a school or hospital-type building must imperatively conduct an environmental audit of the site and the Integrative Design Process credit will become a prerequisite for the development of a new project in the medical sector. LEED will also reward certain types of projects based on specific criteria that aim to maximize the performance of a building according to its use. This is notably the case for medical establishments, which are awarded additional points for the choice of materials and medical furniture with non-toxic content in order to further protect the health of the patients who occupy the LEED building.

If you are on a project that does not belong to one of these specific types of buildings, then the general certification system may be applied (New Construction and Major Renovation).

Which system should I choose if I have several buildings ? Can we certify several buildings on the same site at once?
