Overview
ISO/TR 5911:2023 - "Light and lighting – Commissioning of lighting systems in buildings – Explanation and justification of ISO/TS 21274" - is a technical report that explains and justifies the requirements in ISO/TS 21274. Its purpose is to support correct understanding, national implementation and practical application of commissioning procedures for building lighting systems. The document clarifies background rationale, provides detailed examples and expands on roles, activities and documentation needed to deliver lighting systems that meet design intent.
Key topics and technical requirements
- Scope and purpose: Guidance to interpret and implement ISO/TS 21274 for commissioning lighting systems in buildings.
- Commissioning benefits & need: Addresses complexity introduced by LED technology, digital controls, IoT integration and human‑centric lighting, and the role of commissioning to secure quality and design intent.
- Commissioning content: Explanations of typical commissioning tasks including:
- Installation checks (equipment type, placement, aiming for sensors/luminaires)
- Operation checks (local and remote controls, simulated sensor inputs, control logic verification)
- Performance tests (system behaviour under designed operating conditions)
- Calibration and configuration (problem analysis, parameter tuning)
- Methods & selection: Classification and selection criteria for commissioning methods appropriate to system complexity and project requirements.
- Roles & responsibilities: Guidance for owners/tenants, design teams, contractors/subcontractors, and the commissioning team.
- Phased activities: Pre‑commissioning, installation, field commissioning and post‑occupancy stages.
- Documentation requirements: Clarifies deliverables required by ISO/TS 21274 such as the commissioning plan, commissioning specification, inspection/calibration reports, issues log, training plan and final commissioning report.
- Normative references: ISO/TS 21274, ISO 52000‑1 and CIE S 017.
Practical applications and users
ISO/TR 5911:2023 is practical for professionals involved in the lifecycle of lighting systems:
- Facility owners and tenants specifying performance and acceptance criteria
- Architects and lighting designers aligning design intent with commissioning requirements
- Electrical contractors, integrators and suppliers executing installation, controls and configuration
- Commissioning agents and building engineers running tests, calibration and handover processes
- Facility managers and operators receiving training and documentation at handover
Use cases include projects with LED controls, integrative lighting, energy‑performance objectives, and buildings that require verified lighting performance for comfort, safety or health.
