Project Types


The features of the WELL Building Standard™ (WELL) can be applied across many real estate sectors, however the WELL Building Standard version 1.0 is applicable specifically to commercial and institutional buildings. Furthermore, not all WELL features apply to all buildings, depending on the stage of construction. WELL v1 is therefore further organized into project types, which take into account the specific set of considerations that are unique to a particular building type or phase of construction.

For WELL v1, there are three project types outlined below. If you’re interested in tracking the progress of a specific project type towards WELL Certification™, download the project checklist.

Entire buildings present opportunities for implementation of the greatest number of WELL features. This project type applies to new and existing buildings and addresses the full scope of project design and construction as well as aspects of building operations. It is relevant for office buildings where a minimum of 90% of the total floor area is occupied by the building owner and is operated by the same management (i.e., up to 10% of the building may be occupied by a different tenant or operated by different management). For example, a large office building may rent out the ground floor for retail or restaurant purposes; in these cases, the non-office area would not be subject to requirements of the WELL Building Standard or used in area calculations.
