    • 24 Preconditions, 102+ Optimizations; total ~110 max points.
    • Built on public health/building science research.
    • Certification model: tiers (Bronze 40pts, Silver 50pts, Gold 60pts, Platinum 80pts) with concept minimums; requires documentation review + on-site testing.

    Why Organizations Use It

    Drives occupant productivity, retention, ESG reporting; complements LEED. Mitigates health risks, boosts rents/values (e.g., 7.7% higher rents). Builds stakeholder trust via verified outcomes; voluntary but tenant-demanded.

    Implementation Overview

    Phased: gap analysis, scorecard, design/ops integration, verification (testing by agents), recert every 3yrs. Applies universally; cross-functional teams key. Costs include fees (~$0.16/sqft review), testing; suits all sizes via Core/Residential paths.
