Introduction

Building Information Modellinginformation 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/DTS 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.

4 Principal structure
4.1 General

A lighting system (for example a luminaire or a sensing device) consists out of properties which describes

it and make it possible to communicate about it in 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);

ISO/DTS 7127:2023(E)
— 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 named “Globally unique identifier” (PA001).

Identifier given to a product that guarantees its uniqueness throughout its entire life. (defined in

ISO 6707-2:2017, 3.2.46).
[SOURCE: 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 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

globally unique identifier.

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 named “Names in language en-EN” (PA016).
The name of the property.
4.2.5 Description
In ISO 23386:2020 named “Descriptions in language en-EN” (PA018).
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 named “Symbols of the property in a given property group” (PA022).

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 80000-1:2009].

4.2.7 Format, Unit
In ISO 23386:2020 named “Digital format” (PA037).
© ISO 2023 – All rights reserved 3
---------------------- Page: 9 ----------------------
ISO/DTS 7127:2023(E)

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 named “Units” (PA033).

Concept type representing a scale that enables a value to be measured. Properties that do not have a unit

are be designated as not applicable (n.a.).
4.2.8 Value set
In ISO 23386:2020 named “List of possible values in language en-EN” (PA039).

Collection of acceptable values for a property. Values outside the value set are not permitted. Multiple

values may be possible for some properties.
4.2.9 Examples
In ISO 23386:2020 named “Examples in language en-EN” (PA019).
Samples for a value of the specific property.
4.3 Further IT-related attributes

Where potential attributes are not specified in 4.2, they may be defined separately within a data-

dictionary. These attributes can be found in ISO 23386:2020:

— Definitions in language en-EN (PA017): A description of the attribute in order to define it

unambiguously;

— Method of measurement (PA029): Evaluation of construction products to ensure their suitability

according to requirements in harmonised technical specifications;

— Name of the defining values (PA034): In a table of values, this attribute provides the name of the

column headers;

— Data type (PA030): Format for expressing the value of the property. This can be understood as the

storage type from a software perspective. (ISO/IEC 11404 subclause :2007, 8.1) Examples: String,

Float, Integer;
— Status (PA002): Status of the property during its life cycle. Example: Active;

— Date of creation (PA003): Date of validation of the property creation request. All dates in

accordance with ISO 8601. Format=YYYY-MM-DDThh:mm:ssTZD. Example: 2014-04-30T10:39:53Z;

— Date of activation (PA004): Date after when the property can be used;
— Date of last change (PA005): Date of validation of the last change request;
— Date of revision (PA006);
— Date of version (PA007);

— Date of deactivation (PA008): Date when property becomes obsolete. The property is maintained

in the dictionary;
— Version number (PA009): Enables tracking of major changes;
4 © ISO 2023 – All rights reserved
---------------------- Page: 10 ----------------------
ISO/DTS 7127:2023(E)

— Revision number (PA010): Enables tracking of minor changes. If the version number changes, the

revision number starts again at 1. Examples: new translation, changes of typos;

— List of replaced properties (PA011): Identifier of the replaced property (or properties). List of

GUIDs;

— List of replacing properties (PA012): Identifier of the replacing property (or properties). List of

GUIDs;

— Deprecation explainationexplanation (PA013): Reason of deprecation. Deprecated may indicate

the property will be removed in the future. This explaination has toexplanation shall be written in

international English (EN).

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/DTS 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.

4 Principal structure
4.1 General

A lighting system (for example a luminaire or a sensing device) consists out of properties which

describes it and make it possible to communicate about it in 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.

ISO/DTS 7127:2023(E)
4.2.2 GUID
In ISO 23386:2020 named “Globally unique identifier” (PA001).

Identifier given to a product that guarantees its uniqueness throughout its entire life (defined in

ISO 6707­2:2017, 3.2.46).

This attribute identifies the property unambiguously. A Globally Unique identifier GUID is generated

using an algorithm. This machine­readable code will allow matching across databases, lists and data

template.

In IFC and ISO 12006­3 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

globally unique identifier.

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 named “Names in language en-EN” (PA016).
The name of the property.
4.2.5 Description
In ISO 23386:2020 named “Descriptions in language en-EN” (PA018).
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 named “Symbols of the property in a given property group” (PA022).

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 80000-1:2009].

4.2.7 Format, Unit
In ISO 23386:2020 named “Digital format” (PA037).

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 named “Units” (PA033).

Concept type representing a scale that enables a value to be measured. Properties that do not have a

unit are be designated as not applicable (n.a.).
4.2.8 Value set
In ISO 23386:2020 named “List of possible values in language en-EN” (PA039).
© ISO 2023 – All rights reserved
---------------------- Page: 8 ----------------------
ISO/DTS 7127:2023(E)

Collection of acceptable values for a property. Values outside the value set are not permitted. Multiple

values may be possible for some properties.
4.2.9 Examples
In ISO 23386:2020 named “Examples in language en-EN” (PA019).
Samples for a value of the specific property.
4.3 Further IT-related attributes

Where potential attributes are not specified in 4.2, they may be defined separately within a data

dictionary. These attributes can be found in ISO 23386:2020:

— Definitions in language en-EN (PA017): A description of the attribute in order to define it

unambiguously;

— Method of measurement (PA029): Evaluation of construction products to ensure their suitability

according to requirements in harmonised technical specifications;

— Name of the defining values (PA034): In a table of values, this attribute provides the name of the

column headers;

— Data type (PA030): Format for expressing the value of the property. This can be understood as

the storage type from a software perspective. (ISO/IEC 11404:2007, 8.1) Examples: String, Float,

Integer;
— Status (PA002): Status of the property during its life cycle. Example: Active;

— Date of creation (PA003): Date of validation of the property creation request. All dates in

accordance with ISO 8601. Format=YYYY -MM -DDThh: mm: ssTZD. Example: 2014-04-30T10:39:53Z;

— Date of activation (PA004): Date after when the property can be used;
— Date of last change (PA005): Date of validation of the last change request;
— Date of revision (PA006);
— Date of version (PA007);

— Date of deactivation (PA008): Date when property becomes obsolete. The property is maintained

in the dictionary;
— Version number (PA009): Enables tracking of major changes;

— Revision number (PA010): Enables tracking of minor changes. If the version number changes, the

revision number starts again at 1. Examples: new translation, changes of typos;

— List of replaced properties (PA011): Identifier of the replaced property (or properties). List of

GUIDs;

— List of replacing properties (PA012): Identifier of the replacing property (or properties). List of

GUIDs;

— Deprecation explanation (PA013): Reason of deprecation. Deprecated may indicate the property

will be removed in the future. This explanation shall be written in international English (EN).
