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. Scope covers new/existing buildings across types like offices, residential, hospitality. Key approach: evidence-based Preconditions (mandatory) and Optimizations (points-based) across 10 concepts.
Key Components
- 10 core concepts: Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, Community (+ Innovation).
- 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.
ISO 27701 Details
What It Is
ISO/IEC 27701 is the international standard providing requirements and guidance for establishing, implementing, maintaining, and improving a Privacy Information Management System (PIMS). It focuses on managing personally identifiable information (PII) lifecycle for controllers and processors, using a risk-based PDCA (Plan-Do-Check-Act) methodology aligned with ISO/IEC 27001:2022.
Key Components
- Clauses 4–10 extend management system requirements for privacy.
- Annex A (controllers) and Annex B (processors) specify privacy controls.
- Mappings to GDPR (Annex D) and other standards.
- Certification via accredited bodies, often integrated with ISO 27001 audits.
Why Organizations Use It
- Demonstrates accountability for global privacy laws like GDPR, CCPA.
- Mitigates regulatory fines, breach risks, vendor exclusions.
- Builds trust, enables procurement differentiation, reduces compliance costs.
Implementation Overview
- Phased: discover/scope, design/plan, implement/operate, validate/improve.
- Involves PII inventory, DPIAs, DSR processes, training.
- Suits all sizes/industries handling PII; voluntary certification with 3-year cycle.
