Appendix D: Feature Types and Verification Methods

Parts of the WELL Building Standard fall into one of three categories with respect to the interventions necessary for their completion – design elements, protocols or performance standards. Design standards require that a specific technology or design strategy be used. Protocols are also prescriptive, but for building or company policies or schedules. Performance-based standards mandate environmental conditions and therefore are affected by both building design and operation. They are also technology- and practice-neutral, allowing flexibility in how a project meets acceptable quantified thresholds.

The following table also displays the type of documentation relevant (if any) for each Part of a Feature. Project teams should consult this table to understand what document needs to be submitted to demonstrate that the Part has been satisfied, or if no action is necessary because an assessor will check the Part on-site during the Performance Verification.
