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

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.
