This is a legacy version of the WELL Building Standard. Please check the latest version here.

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.

This project type is relevant for office projects only occupying a portion of the space in a building, or those that occupy an entire existing building not undergoing major renovation. In Core and Shell buildings that are WELL Certified™, some WELL features may already apply towards New and Existing Interiors certification, making certification easier. WELL Certification for tenants is also possible in buildings that have not first achieved Core and Shell certification.
