WELL PERFORMANCE VERIFICATION

Leading with performance





WELL is the premier framework for certifying and creating spaces that advance health and well-being around the world. Performance Verification helps ensure that evidence-based health and well-being strategies have been implemented and are performing as planned.


You can't improve what you don't measure.

Types of Performance Verification

  • Onsite testing

    Performance testing and analysis of onsite environmental conditions

  • Documentation review

    Confirmation that all design, operational and policy documentation meet expectations

Why Performance Verification Matters
