WELL Details
What It Is
WELL Building Standard v2 is a performance-based certification framework administered by the International WELL Building Institute (IWBI). It focuses on designing, operating, and verifying buildings to advance human health and well-being through evidence-based strategies. Its people-first approach emphasizes measurable occupant outcomes via 10 core concepts like Air, Water, and Mind, using mandatory Preconditions and optional Optimizations.
Key Components
- 10 concepts: Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, Community (+ Innovation).
- 24 Preconditions (pass/fail) and 102 Optimizations (points-based).
- Built on public health and building science research.
- Certification model: Bronze (40 points), Silver (50), Gold (60), Platinum (80), with concept minimums at higher tiers.
Why Organizations Use It
Drives productivity, tenant retention, ESG reporting, and higher rents. Mitigates health risks, complements LEED for holistic sustainability. Builds stakeholder trust via verified performance.
Implementation Overview
Multi-phase: gap analysis, scorecard development, documentation, on-site verification, recertification every 3 years. Applies to new/existing buildings, all sizes/industries; requires third-party testing.
