ISO 50001 Details
What It Is
ISO 50001:2018 is an international certification standard for Energy Management Systems (EnMS). It provides a systematic framework to improve energy performance, including efficiency, use, and consumption, applicable to all organization types and sectors. Built on the Plan-Do-Check-Act (PDCA) cycle and Annex SL High-Level Structure, it emphasizes risk-based planning and continual improvement.
Key Components
- Clauses 4-10 cover context, leadership, planning (energy review, SEUs, EnPIs, EnBs), support, operation, evaluation, improvement.
- Requires documented energy policy, data collection plans, operational controls, procurement criteria.
- Core principles: leadership accountability, measurable performance via normalized indicators.
- Optional third-party certification per ISO 50003.
Why Organizations Use It
- Drives cost savings (4-20% energy reduction), resilience, GHG reductions.
- Meets regulatory expectations (e.g., EU directives), enhances ESG reporting.
- Manages energy risks, integrates with ISO 9001/14001.
- Builds stakeholder trust via auditable improvements.
Implementation Overview
- Phased: gap analysis, energy review, controls deployment, audits.
- Suited for all sizes/sectors; 6-12 months typical.
- Involves metering, training, management reviews; certification optional via accredited bodies.
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 execution and conformity assessment of structural steel and aluminium components/kits for construction works. Primary purpose: ensure safe fabrication, assembly, and CE marking via risk-based 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 (welding, tolerances, corrosion protection, NDT).
- Core: ISO 3834 welding alignment, material traceability, inspection regimes. AVCP systems with Notified Body oversight.
Why Organizations Use It
Mandatory for EU market access; reduces liability, rework. Drives capability in welding/traceability; enhances competitiveness, trust via CE marking.
Implementation Overview
Phased: gap analysis, FPC build, personnel quals, NB certification, surveillance. Targets fabricators; 6-12 months typical; audits ongoing.
