    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 across indoor environments and organizational policies. Its people-first approach uses preconditions for minimum requirements and optimizations for points.

    Key Components

    • **10 core conceptsAir, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, Community (plus Innovation).
    • 24 Preconditions (mandatory) and 102 Optimizations (point-earning).
    • Built on public health research; certification via Bronze (40 pts), Silver (50), Gold (60), Platinum (80) with concept minimums.
    • Requires on-site performance verification and documentation review.

    Why Organizations Use It

    Enhances occupant health, productivity, and ESG reporting; reduces absenteeism and boosts rents/values. Voluntary but differentiates in leasing/HR; manages IEQ risks complementing LEED.

    Implementation Overview

    Phased: enrollment, scorecard, documentation, third-party review/testing, certification (new/existing buildings). Cross-functional teams; 12-18 months typical; recertify every 3 years with monitoring.
