The Well Building Standard is the world’s first evidence-based system designed for measuring, certifying, and monitoring building features that impact health and well-being.

The WELL Building Standardᵀᴹ version 2 (WELL v2ᵀᴹ) is a vehicle for buildings and organizations to deliver more thoughtful and intentional spaces that enhance human health and well-being.
