The WELL certification, differently from the previous ones described, places at the centre of the evaluation the psycho-physical conditions of those who occupy an internal area. The protocol is also managed in this case by the American USGBC, the same that deals with the issue of LEED certification.
The objective of the certification is to be able to manage and live in an optimal way the time spent inside closed environments, as they can be in the office or in industries. However, the certification is applicable to all types of buildings, including residential buildings.
