Overview
CEN ISO/TS 7127:2024 (ISO/TS 7127:2023 adopted by CEN) specifies building information modelling (BIM) properties for lighting systems. It defines a standardized set of attributes to describe luminaires, sensing devices and lighting systems so that product data can be exchanged unambiguously between manufacturers, BIM platforms, databases and facility-management tools. The technical specification organizes properties into discipline-based tables and prescribes machine- and human-readable identifiers (GUID, ID) to enable reliable mapping between data providers and requesters.
Key Topics
- Scope and purpose: Establishes essential properties for the design, description and maintenance of lighting systems in digital environments.
- Property structure: Attributes follow ISO 23386 methodology and include GUID, ID, Name, Description, Symbol, Format/Unit, Value set, and Examples.
- Property categories: Properties are grouped into tables for:
- Mechanical (ID 01)
- Electrical (ID 02)
- Emergency lighting (ID 03)
- Photometric (ID 04)
- Sensing devices (ID 05)
- Mounting & accessory (ID 06)
- Marketing (ID 07)
- Operations & maintenance (ID 08)
- Environmental (ID 09)
- Data mapping and interoperability: Emphasizes identifier mapping to support exchange of luminaire data and sensor information across different databases and BIM systems.
- Quality and processing: Aims to improve data quality, reduce misinterpretations and accelerate automated processing in digital building design and maintenance workflows.
Applications
- Integrating manufacturer product data into BIM models and product data sheets.
- Exchanging photometric and electrical data between lighting design software, BIM platforms (IFC-based tools) and asset-management systems.
- Specifying lighting systems in digital tendering, procurement and facility-management processes.
- Enabling consistent environmental and maintenance information for lifecycle planning and sustainability reporting.
Who uses this standard
- Lighting designers and engineers for accurate modelling and simulation.
- BIM managers and digital twin teams to standardize lighting metadata.
- Manufacturers and product data managers to publish interoperable luminaire data.
- Software developers and database providers implementing lighting BIM properties.
- Facilities and maintenance managers using standardized data for operations.

This specification is essential for anyone implementing lighting BIM standards, exchanging luminaire data, or building interoperable lighting datasets for digital building design and maintenance.
