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 concept-based approach organizes requirements into mandatory Preconditions and optional point-earning Optimizations.
Key Components
- **10 core conceptsAir, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, Community (plus Innovation).
- 24 Preconditions and 102 Optimizations totaling up to 110 points.
- Built on public health research; certification tiers (Bronze 40, Silver 50, Gold 60, Platinum 80 points) with concept minimums.
- Requires on-site performance verification and documentation review.
Why Organizations Use It
Drives occupant health, productivity, and ESG reporting; complements LEED for people-centric outcomes. Reduces risks like poor IEQ; boosts rents, retention, reputation.
Implementation Overview
Phased: gap analysis, scorecard, design integration, verification, operations. Applies to new/existing buildings, all sizes/industries globally. Involves cross-functional teams, third-party testing, 3-year recertification.
CSA Details
What It Is
CSA Group standards, such as CSA Z1000 (Occupational Health and Safety Management) and CSA Z1002 (Hazard Identification and Risk Assessment), are consensus-based National Standards of Canada. They provide management system frameworks for OHS, using a Plan-Do-Check-Act (PDCA) approach aligned with ISO 45001, focusing on systematic risk control across industries.
Key Components
- Leadership and policy commitment
- **Planninghazard identification (biological, chemical, ergonomic, physical, psychosocial, safety), risk assessment, objectives
- **Implementationtraining, operational controls, emergency preparedness
- **Checkingmonitoring, audits, incident investigation
- Management review for improvement No fixed controls; emphasizes hierarchy of controls and worker participation.
Why Organizations Use It
Meets legal duties via incorporation-by-reference, demonstrates due diligence, reduces incidents/liability. Builds safety culture, operational efficiency, stakeholder trust.
Implementation Overview
Phased: gap analysis, policy development, training, audits. Suits all sizes/industries, esp. high-risk (manufacturing, construction). Certification through SCC-accredited bodies optional but common.
Key Differences
| Aspect | WELL | CSA |
|---|---|---|
| Scope | Occupant health across 10 concepts (Air, Water, etc.) | OHS management, hazard ID, risk assessment/control |
| Industry | Buildings, real estate globally (offices, residential) | All industries, Canada-focused worker safety |
| Nature | Voluntary performance-based certification | Consensus standards, often mandatory via regulation |
| Testing | On-site performance verification, continuous monitoring | Internal audits, third-party certification optional |
| Penalties | Loss of certification, no legal fines | Fines/prosecution if regulation-referenced |
