WELL
Certification for occupant health in buildings
EN 1090
EU standard for execution of steel and aluminium structures.
Quick Verdict
WELL certifies buildings for occupant health via performance verification globally, while EN 1090 mandates CE marking for structural steel/aluminium in EU via Factory Production Control. Companies adopt WELL for ESG/wellness differentiation; EN 1090 for legal market access.

WELL Details
What It Is
The 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. Its evidence-based approach emphasizes measurable outcomes across environmental quality, operations, and policies.
Key Components
- **10 core conceptsAir, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, Community (plus Innovation).
- 24 Preconditions (mandatory pass/fail) and 102 Optimizations (point-earning).
- Built on public health research; certification tiers via points (Bronze 40, Silver 50, Gold 60, Platinum 80) with concept minimums.
- Requires third-party documentation review and on-site performance verification.
Why Organizations Use It
- Enhances occupant health, productivity, and ESG reporting.
- Differentiates assets with verified people metrics; boosts rents, retention.
- Mitigates risks like poor IEQ; complements LEED for holistic sustainability.
- Builds stakeholder trust through rigorous, transparent verification.
Implementation Overview
- Phased: gap analysis, scorecard, design/operations integration, verification, recertification (3 years).
- Applies to new/existing buildings, all sizes/industries.
- Cross-functional teams; continuous monitoring optional.
EN 1090 Details
What It Is
EN 1090 is a harmonized European standard family (EN 1090-1, -2, -3) under the Construction Products Regulation (CPR). It governs conformity assessment and technical execution of structural steel and aluminium components/kits for construction works. Primary purpose: ensure safe fabrication, assembly, and market placement via CE marking. Key approach: risk-based scaling through Execution Classes (EXC1-EXC4).
Key Components
- **EN 1090-1Conformity assessment, Factory Production Control (FPC) certification, Declaration of Performance (DoP).
- **EN 1090-2/-3Technical rules for steel/aluminium (materials, welding, tolerances, corrosion protection, NDT).
- Core principles: traceability, welding per ISO 3834, inspection regimes.
- Compliance model: Notified Body certification with ongoing surveillance.
Why Organizations Use It
- Mandatory for EU/EEA market access (CE marking required).
- Mitigates liability, reduces rework via disciplined processes.
- Builds trust, enables high-risk projects (e.g., bridges, stadiums).
- Strategic edge: certified capability for tenders.
Implementation Overview
Phased: gap analysis, FPC build, personnel training (welding coordinator), ITT/ITC, NB audits. Applies to fabricators; 3-12 months typical. Requires certification for EXC-rated production.
