The WELL Building Standard assesses and rates the performance of buildings in delivering spaces that enhance human health and wellbeing. Thereby, the tool aims to support buildings and organizations in delivering more thoughtful and intentional spaces by setting performance standards for design interventions, operational protocols and policies and a commitment to fostering a culture of health and wellness. The tool rates buildings’ performance using individualized, point-based scorecards depending on the use and occupational structure of the building (owner-occupied or rented).

Tool Outcome

Projects pursuing WELL Certification can earn points based on performance outcomes for various policy, design and operational strategies. Assessment is based on individualized scorecards and can lead to certification (Bronze – Silver – Gold – Platinum).

– Air
