The life cycle assessment (LCA) at building level is a widely used methodology to assess important environmental impacts (e. g. global warming, ozone depletion, photochemical ozone creation, acidification, or eutrophication potential) of the building over its life cycle. The basic material data for such LCA at building level are given in EPDs. In many European member states national EPD programme operators in conformity to EN ISO 14025 were developed, producing EPDs in conformity to EN 15804. In detail, the Product Category Rules (PCRs) differ from one programme to the other, as for some aspects EN 15804 rather gives a frame, which is interpreted and implemented in EPD programmes in different ways.
Until now programme operators run their own databases with EPDs mainly in form of product lists supplemented by PDF documents. However using EPD data in LCA at building level calls for EPD data provided in databases, which is why initiatives for databases are launched in many member states. The independent development of these databases brings the risk of a great variety of data formats and thus the danger of incompatibility of data.
Hence, InData was founded as a network aiming at the initiation of an international LCA data network structure for construction products based on EPD information. This includes a common standard for the data format, and hence, a high compatibility and transparency of data.
A number of MS decided on a voluntary basis to start this initiative of harmonization. The group consists of:
- EPD programme operators
- Data set providers
- Data base providers
- Data set format developers
- Building assessment operators
NOTE: dataset providers offer a set of LCA data (generic, representative, average, product specific data) while data base providers offer a front end, where datasets (own or others) are provided.
