General

Environmental product performance can

be determined by environmental assessment tools e.g. LCA

– Provide indications on improvement – Hard to realise when product is already implemented on the market – Product designers should optimise products in design stages DfE

Process and Product Model

Product description

– Process model LCA = life cycle processes – Product model CAD = product construction & assembly

Influenced by product properties and

processes of life cycle

Connect models for environmentally

ptimising products by designers

– Description of products main approach for linking

Data exchange formats

LCA data documentation format

regulated in ISO/TS 14048

– Process data

No common LCA data exchange format CAD data exchange format STEP

– Standard for the Exchange of Product Model Data (ISO 10303) – Product data description

Requirements for data exchange

Consistent data structuring Possibility to convert data formats to a

general exchange format

Possible ways for data exchange:

– XML (Extensible Markup Language) – Spreadsheets – Interface

Data exchange possibilities between

CAD and LCA software tools

Product model developed in CAD Data transfer to LCA manually

– Calculation of material masses – Selection of life cycle processes from database – Research for processes not derivable from product model

Data necessary to exchange

– Volumes of components, materials, product structure

Processes given in database

– Indications needed when different life cycle processes are possible – Database should be enlarged

Summary

CAD Product models can be transferred to

LCA

– Converted to process models – Exchangeable data formats necessary – Data to be exchanged needs to be specified – Life cycle database needs to be enlarged – LCA results initiate environmental improvements – Increase awareness of LCA data needs among product designers
