This document describes how product catalogue data for building services products is exchanged by means of ISO 16739-1 (Industry Foundation Classes, IFC) and EN 17549-2 from manufacturers to designers of building services systems. This document specifies how the product catalogue structures and content are set up using the definitions stored in a data dictionary. In scope of this document are: — processes for the provision and exchange of product catalogues; — rules for the geometrical representation of products; — representation of products, product classes, ports, in/outlets, components and accessories by using IFC; — representation of properties in IFC and the use of IFC constraints for the representation of product variants; — representation of parametric geometry and the generation of IFC geometries for selected variants; — calculation of article number. The resulting product catalogue can be used by designers to select the desired products and integrate them into their model of the building services system. The expected audience of this document are software providers for the built environment sector and professionals working in the sector who create product catalogues or use product catalogues by means of software tools. Not in scope of this document is the representation of properties in data dictionaries. The use of data dictionaries is described in ISO 16757-4.
Abstract
Overview
ISO 16757-5:2025 - Data structures for electronic product catalogues for building services - Part 5: Product catalogue exchange format - defines a standardized exchange format for manufacturer product catalogues used in building services. It specifies how product catalogue data is packaged and exchanged using IFC (ISO 16739-1) and EN 17549-2, driven by definitions stored in data dictionaries. The standard focuses on the format and structure of catalogue data to enable reliable transfer from manufacturers to designers and software tools in the built environment.
Key topics and technical requirements
- IFC-based product representation: Mapping of products, product classes, components, accessories, ports and in/outlets into IFC structures and metadata.
- Geometry rules: Guidance for symbolic and shape geometry, parametric geometry definitions, and generation of IFC geometries for selected product variants.
- Properties and constraints: Representation of properties in IFC, use of IFC constraints to express product variants and dynamic property behavior (note: data dictionary property definitions are covered in ISO 16757-4).
- Processes for provision and exchange: Defined workflows for creating, providing and integrating product catalogues into technical system models.
- Ports, in/outlets and spaces: Standardized representation to support connectivity, routing and spatial coordination in BIM models.
- Part number calculation: Rules for deriving article numbers within catalogue structures.
- Supporting artifacts: Metadata, JavaScript (ECMAScript) functions, and informative annexes with file examples and procedures to aid implementation.
Applications and practical value
- Enables BIM-compatible product selection and direct integration of manufacturer products into building services models for HVAC, plumbing, fire protection, electrical and other MEP systems.
- Improves interoperability between manufacturer catalogues and design software (CAD/BIM/analysis tools) using IFC as the exchange backbone.
- Supports parametric product variants so designers can generate accurate geometry for coordination, clash detection, modeling and simulation.
- Facilitates automation in procurement and specification workflows through consistent part-number calculation and catalogue metadata.
- Useful for facility managers and simulation engineers who need accurate product data for operation, maintenance and performance analysis.
Who should use it
- Software vendors (BIM/MEP/catalogue management tools) implementing IFC import/export and catalogue handling.
- Manufacturers producing digital product catalogues for building services products.
- Designers, MEP engineers and BIM coordinators who integrate manufacturer data into technical system models.
