ISO 22057:2022

Overview

ISO 22057:2022 - Sustainability in buildings and civil engineering works - defines data templates to make Environmental Product Declarations (EPDs) and generic Life Cycle Assessment (LCA) data machine‑interpretable for use in Building Information Modelling (BIM). The standard specifies principles and requirements for structuring EPD and generic LCA information so it can be integrated into information‑driven design, construction, operation and end‑of‑life processes. It enables consistent exchange of environmental and technical product data in BIM but does not itself perform the environmental assessment at the construction works level.

Key technical topics and requirements

• Data templates and data sheets: Defines how to create standardized, machine‑readable data templates and resulting data sheets to represent EPD content.
• Alignment with ISO 23386 / ISO 23387: Requires use of these standards for data template creation and management of metadata and semantics.
• EPD content structure: Specifies groups and properties for EPD general information, methodological framework, scenarios (A, B, C modules and Module D), environmental indicators, and additional environmental information.
• Generic LCA data: Provides structure for including generic LCA datasets when specific EPDs are not available.
• Terminology and GUIDs: Emphasises terminology alignment, use of globally unique identifiers (GUIDs), and data dictionaries to ensure interoperability.
• Interoperability & mapping: Includes informative annexes and UML diagrams to relate EPD/LCA concepts to other data sources (e.g., ILCD, OpenEPD, INIES) and guidance for smart CE marking.

Practical applications

• Integrating EPDs into BIM workflows for lifecycle impact considerations during design and procurement.
• Enabling automated extraction and aggregation of product environmental data for embodied carbon and LCA tools connected to BIM.
• Supporting manufacturers and EPD programme operators to publish EPDs in a machine‑readable format that BIM tools can consume.
• Allowing project teams to use generic LCA data where product‑specific EPDs are absent, improving completeness of environmental models.

Who should use ISO 22057:2022

• Architects, engineers and BIM managers implementing environmental assessment within BIM.
• LCA practitioners and sustainability consultants assembling product datasets.
• Product manufacturers and EPD programme operators preparing machine‑readable EPDs.
• Software vendors building BIM, LCA and digital procurement tools.
• Owners, clients and policy makers seeking interoperable product environmental data.

Related standards

• ISO 23386, ISO 23387 (data templates and dictionaries)
• ISO 21930 and EN 15804 (EPD and PCR background)
• ISO 14040 / ISO 14044 (LCA methodology)
• ISO 19650 (BIM information management)

Using ISO 22057:2022 helps bridge EPD/LCA data and BIM through standardized, interoperable data templates - improving accuracy, automation and traceability in environmental assessment workflows.
