Light and lighting — Building information modelling properties for lighting — Lighting systems
This technical specification identifies and clarifies lighting properties for digital building design and maintenance. This document provides all the needed properties to design and to describe lighting systems. These properties are intended to be used for mapping between data providers and requesters. The mapping of the identifiers enables the exchange of luminaire and sensing device data within different databases. The unambiguous mapping and description of properties improves the data quality, reduces misinterpretations and the processing time in digital environments. Therefore, the properties listed in this document establish the essential description of lighting systems in BIM systems and databases. The listed properties in this document are used to structure the product data sheet which is complemented with real product information.
Lumière et éclairage — Propriétés de modélisation des informations de la construction pour l'éclairage — Systèmes d'éclairage
La présente spécification technique identifie et clarifie les propriétés de l’éclairage pour la conception et la maintenance numériques des bâtiments. Le présent document fournit toutes les propriétés nécessaires à la conception et à la description des systèmes d’éclairage. Ces propriétés sont destinées à être utilisées pour la mise en correspondance entre les fournisseurs et demandeurs de données. La mise en correspondance des identifiants permet l’échange de données concernant les luminaires et les capteurs entre différentes bases de données. La mise en correspondance et la description des propriétés, lorsqu’elles sont dépourvues d’ambiguïtés, améliorent la qualité des données, réduisent les erreurs d’interprétation et raccourcissent le temps de traitement dans les environnements numériques. Par conséquent, les propriétés énumérées dans le présent document établissent la description essentielle des systèmes d’éclairage dans les systèmes et bases de données BIM. Les propriétés énumérées dans le présent document servent à structurer la fiche technique du produit en la complétant d’informations réelles sur les produits.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
Building information modelling (BIM) is a concurrent process that gives engineering and construction
professionals the tools to more efficiently plan, construct, and manage buildings and infrastructure.
Within standardisation committees much work is being performed to define the fundamental principles
of BIM that will allow this to happen in an effective and consistent manner.
For lighting applications, it is essential that this work is monitored and where required input is made to
ensure that the requirements for lighting applications are considered.

TECHNICAL SPECIFICATION ISO/TS 7127:2023(E)
Light and lighting — Building information modelling
properties for lighting — Lighting systems
1 Scope
This technical specification identifies and clarifies lighting properties for digital building design and
maintenance.
This document provides all the needed properties to design and to describe lighting systems. These
properties are intended to be used for mapping between data providers and requesters. The mapping
of the identifiers enables the exchange of luminaire and sensing device data within different databases.
The unambiguous mapping and description of properties improves the data quality, reduces
misinterpretations and the processing time in digital environments. Therefore, the properties listed
in this document establish the essential description of lighting systems in BIM systems and databases.
The listed properties in this document are used to structure the product data sheet which is
complemented with real product information.

characteristics of any construction works.

4 Principal structure
4.1 General
A lighting system (for example a luminaire or a sensing device) is described by specific properties,
providing the possibility to communicate about it in an application or specification.
The properties for lighting systems have been organized in tables listed in Clause 5 according to
different disciplines. This sub-division is indicative only and not to be taken as exclusive:
— Mechanical properties – ID 01 (Table 1);
— Electrical properties – ID 02 (Table 2);
— Emergency lighting properties – ID 03 (Table 3);
— Photometric properties – ID 04 (Table 4);
— Sensing device properties – ID 05 (Table 5);
— Mounting & Accessory properties – ID 06 (Table 6);
— Marketing properties – ID 07 (Table 7);
— Operations & Maintenance properties – ID 08 (Table 8);
— Environmental properties – ID 09 (Table 9).
4.2 Detailed description of set of attributes
4.2.1 General
The structure of the attributes is according to ISO 23386:2020 and enhanced by the property ID.
The properties have no mandatory or optional aspect. All properties are equal in importance and
hierarchy. The use case and the application provide a structure and are mandatory to the properties.
4.2.2 GUID
In ISO 23386:2020, PA001 named “Globally unique identifier”.
Identifier given to a product that guarantees its uniqueness throughout its entire life (defined in
ISO 6707-2:2017, 3.2.46).
This attribute identifies the property unambiguously. A Globally Unique identifier GUID is generated
using an algorithm. This machine-readable code will allow matching across databases, lists and data
template.
In ISO 16739-1 (IFC) and ISO 12006-3 the compressed version of GUID is used. It can be uncompressed
to the standard GUID with open tools.
4.2.3 ID
This attribute identifies the property unambiguously. It is human-readable and corresponds to the
GUID.
Note The ID always starts with the table number from 4.1 followed by a dash and an individual serial
number with four digits.
4.2.4 Name
In ISO 23386:2020, PA016 named “Names in language en-EN”.
The name of the property.
4.2.5 Description
In ISO 23386:2020, PA018 named “Descriptions in language en-EN”.
This attribute is used to provide a plain language description of the property.
For some descriptions the name is enough. To avoid the repeating of the name, just “identical with
name.” is entered.
4.2.6 Symbol
In ISO 23386:2020, PA022 named “Symbols of the property in a given property group”.
Symbols for quantities are given in the ISO 80000 and IEC 80000 series. The symbols for quantities are
written in italics. A given symbol can indicate different quantities. (ISO 80000-1:2022).
4.2.7 Format, Unit
In ISO 23386:2020, PA037 named “Digital format”.
Precision is the maximum number of significant digits that can be represented in a format, or the
number of digits that a result is rounded to [ISO/IEC 60559:2020].
In ISO 23386:2020, PA033 named “Units”.
Concept type representing a scale that enables a value to be measured. Properties that do not have a
unit are to be designated as not applicable (n.a.).
4.2.8 Value set
In ISO 23386:2020, PA039 named “List of possible values in language en-EN”.
