Ökobilanz-Basisdaten für Bauprodukte aus Holz

The sustainability assessment of buildings has been increasingly gaining importance in recent years. This is reflected in the development of comprehensive building certification schemes and standards in this field, the assessment of which is based on the provision of environmental information about the building materials used. At the same time, the construction sector is by far the largest market for wood products. Due to the variety of products and the frequent small and medium-sized enterprise (SME) character, especially within the sawmill industry, the provision of necessary environmental data presents a challenge for the woodworking industry. Therefore, comprehensive life cycle assessment (LCA) datasets were generated within the framework of this research, for building products made from wood, which meet the latest standard requirements for use in the field of sustainable construction. In close cooperation with organizations and companies in the German woodworking industry, the life cycle inventory data for 19 solid wood and engineered wood product categories were recorded and their life cycle impact was assessed according to DIN EN ISO 14040. The datasets - verified by an independent critical review, meet the methodological and qualitative requirements of EN 15804:2012 and can be used in environmental product declarations for wood products by the participating companies and associations. Relevant documents could already be generated in collaboration with the wood working industry during the duration of the project. The generated datasets represent the mean values of the participating companies, weighted according to their production quantities, and can be made available in the required formats in public databases for sustainable construction in Germany. This report also fulfils the necessary demand for a transparent and comprehensive documentation of such records and serves as a background report for the verification of the applied methodology.
