Data structures for electronic product catalogues for building services - Part 1: Concepts, architecture and model (ISO 16757-1:2015)

The primary purpose of ISO 16757 is the provision of data structures for electronic product catalogues to transmit building services product data automatically into models of building services software applications. This includes a meta model for the specification of product classes and their properties and a meta model for the product data which is exchanged in product catalogues. Product data has to follow the specifications for their product groups.
ISO 16757-1:2015 specifies
the underlying concepts,
a generic model specifying the available modelling elements and their relationships, and
a framework for the specification of the Content Parts by describing the elements which are to be provided by these Parts.

Introduction

These Content Parts of this International Standard will define standardised properties for the product

groups and the composition of the technical data model. Furthermore, they determine the specific

programming function-interfaces to layout, calculate, and simulate the products.

There is a growing need for information about building services systems during the planning and design

of buildings. The designers in building services have to execute detailed calculations and simulations

to ensure saving of energy and to satisfy hygienic and comfort criteria in heating, ventilation, air

conditioning, and sanitary plants. They have to provide better and better documentation to verify

the compliance with these requirements. The resulting designs have to describe the complete plants

without internal interference or intersection with the building.

These requirements can only be achieved with modern engineering applications like CAD- and CAE-systems,

calculation programs, BIM tools, and management software. The software systems need exact data of the

used plant components. Each component contributes to the performance data of the whole building.

There are many manufacturers, who provide products to certain sectors of building services (such as

heating, ventilation, air conditioning, sanitary). Others provide only certain product groups (radiators,

heaters, air condition equipment, air pipes, valves, devices).

Classical catalogues provide product data in tables and show the design algorithms in diagrams and

design rules. In addition to the technical properties required for functional design and calculation (e.g.

in the form of curve diagrams), such catalogues also contain the geometry data needed for dimensional

design and construction (e.g. in the form of dimensional drawings with port details) and the descriptive

objects serving for visualization (such as photos, video sequences, or acoustical sequences).

Additionally, nearly all big manufacturers provide their own software (mostly for free) as electronic

catalogues to select, to design, and to calculate their products.

Unfortunately, none of these software solutions meets all the requirements of the planner. Needless

to say, that each program contains only the product range of its manufacturer. So it is not possible to

perform a continuous planning of the plant with products of different manufacturers.

Thus, it is desirable to provide engineering applications which are independent from the manufacturers.

The next problem is that data files from different manufacturers — if available at all — are organized in

different data formats, structures, and terminologies.

Independent CAD-systems and calculation software need to get data and algorithms in a uniform way.

Only if product data and algorithms are automatically available, the calculation and simulation of a

complete HVAC plant is possible.

Software providers cannot afford to provide all data from all product manufacturers in the format

required by their system. Also, product manufacturers cannot provide current information about their

products in the formats of all potential software systems. Thus, we have a typical situation where

standardization is required to improve the exchange of information between business partners.

Within single product groups (e.g. radiators), national initiatives to standardize exchange formats have

already been conducted. But there is a lack of unification of existing formats across all product groups.

Required is a uniform, internationally standardised definition for product catalogue data interchange.

Such a definition eliminates the need to manage different data formats and to use different software

systems to deal with products of different manufacturers, and this leads to a significant reduction of costs

for manufacturers and users. Integrating this data into BIM-systems (Building Information Modelling)

allows data interchange between IT systems. In addition, to the benefit for planning, there will be an

amount of advantages for other software solutions, e.g. facility management and life cycle management.

This International Standard offers for the first time an interface which allows the uniform handling of data

about technical, commercial, maintenance, service, as well as geometry, images, video, and text information.

INTERNATIONAL STANDARD ISO 16757-1:2015(E)
Data structures for electronic product catalogues for
building services —
Part 1:
Concepts, architecture and model
1 Scope

The primary purpose of this International Standard is the provision of data structures for electronic

product catalogues to transmit building services product data automatically into models of building

services software applications. This includes a meta model for the specification of product classes

and their properties and a meta model for the product data which is exchanged in product catalogues.

Product data has to follow the specifications for their product groups.
The standard series is split into two areas:

— Basic concepts like conceptual models, languages, geometry representations, and XML schemas for data

exchange are provided in the Conceptual Parts of the standard series (Parts with a one digit number).

— Using these resources, the Content Parts of this International Standard define for various product

groups of building services concrete models for the description and the exchange of products.

The basic concepts which are provided by the standard series include the following:

— resources for the specification of selection properties and a selection property tree guiding the

selection process to identify the appropriate product variant from a parametric electronic catalogue;

— resources for the specification of dependent properties and their computational functions to

compute their values in dependency from installation parameters;

— resources for the specification of composition relationships between products which can be used to

model structures like bill of materials or accessory relationships;

— resources for a parametric constructed solid geometry (CSG) based geometry representation containing

specific CSG elements geometrical elements which are typical for building services products.

This part of ISO 16757 specifies
— the underlying concepts,

— a generic model specifying the available modelling elements and their relationships, and

— a framework for the specification of the Content Parts by describing the elements which are to be

provided by these Parts.
Not in scope of this part of ISO 16757 are the following:
— a detailed description of the used geometrical primitives;
NOTE Geometry is described in ISO 16757-2.

— a specification of the script language used to exchange algorithms for computing the values of

dependent and computable properties;
NOTE The script language is described in ISO 16757-3.

SIST EN ISO 16757-1:2019
ISO 16757-1:2015(E)

— a specification of the XML Schema specifying the data structures for the catalogue exchange;

NOTE The XML schema is described in ISO 16757-5.
— a description of the relationships to standards of the area of buildingSMART;

NOTE The relationships to standards of the area of buildingSMART is described in ISO 16757-4.

— definition of models for specific product groups.

NOTE 1 Definitions of models for specific product areas are described in ISO 16757-10 et. seq., the Content

Parts of ISO 16757.
NOTE 2 All parts are still under development.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
accessory

product of the same or of different product groups, which can be attached to a product

Note 1 to entry: An accessory is not a different type of product, it plays an ancillary role to another product.

2.2
accessory hierarchy
representation of the dependencies between products and accessories
2.3
article number

manufacturer’s reference number, GTIN, or other identifier identifying the product or constituents of a

product
2.4
building information modelling
BIM

construction of a model that contains the information about a building for all phases of the building life cycle

Note 1 to entry: In many cases, the abbreviation BIM is also used for the result of the building information

modelling, namely the building information model.
2.5
building services

utilities and installations supplied and distributed within a building such as electricity, gas, heating,

water, and communications
[SOURCE: ISO 16484-2]
2.6
building services system
BSS
technical system that provides building services in a building
[SOURCE: ISO 16484-2]
2.7
BSS property
technical property that describes an aspect of the current state of a BSS

Note 1 to entry: A BSS property cannot get a value in a catalogue because the states of the building services

system are not known and will vary according to the specific system and its various system states.

SIST EN ISO 16757-1:2019
ISO 16757-1:2015(E)

EXAMPLE In the example given in 2.10, ‘media volume flow’ and ‘media density’ are BSS properties.

2.8
catalogue metadata
data in the catalogue which contains data about the catalogue itself

EXAMPLE Catalogue metadata include standard numbers, data for version management, the manufacturer’s

name, and global location number, as well as file check details.
2.9
descriptive object
object giving descriptive and/or visual information about the product
EXAMPLE Descriptive objects are pictures, descriptions, videos, etc.
2.10
dynamic property

technical property, that reflects the product’s behaviour under the operating conditions of the building

services system in which the product is installed

EXAMPLE The dynamic property ‘pressure loss of a pipe elbow’ is dependent of the ‘media volume flow’

and the ‘media density’. In a catalogue, the manufacturer of a pipe elbow has to provide a means to allow the

determination of the actual ‘pressure loss’ for various values of ‘media volume flow’ and ‘media density’

Note 1 to entry: A dynamic property does not get a value from a product catalogue because the value of a dynamic

property is dependent on the state of the building services system into which the product will be integrated.

Therefore, the value may vary according to the state. The catalogue normally contains some means which allow

the product user to determine the value of that property in a given state of the building services system.

3 Requirements and fundamentals

The strategic interest of this International Standard is the provision of product data for design,

calculation, and simulation of Building Services systems within engineering application models. This

means it is necessary to exchange machine-readable product data from manufacturers to engineering

applications and to building information models in an automatic way.
Basically, the products are described by three elements (see Figure 1):
— property values;
— representation objects (like geometry);
— descriptive objects (like text documents, pictures, etc.).

In addition, products can be supplemented by a number of accessories which can be optionally selected

in addition to the product itself. Which and ho
