Environmental life cycle assessment of wood-based building materials and building product. Oekobilanzen von Baustoffen und Bauprodukten aus Holz; Zusammenfassung erster Erkenntnisse

Abstract

This report presents a summary of the main studies on the topic carried out at EMPA wood department in the last 4 years.In its first part, the concept of an environmental life cycle analysis (LCA), whose purpose is to quantify the known environmental impacts of a product by means of a systematic input/output analysis, is described. Such evaluation must include all phases of a product's life cycle, from the extraction of resources to the final disposal. Raw material and energy supply are input values, whereas main products, by-products, and emissions to the environment are outputs. It is essential for a meaningful data collection as well as for the final interpretation of the results to define exact system boundaries and explain the models used for data aggregation which are, therefore, described in detail. The report's second part summarizes the results of an environmental assessment of wood as a raw material and construction component, and of some important wood-based products. First, some product-independent ecological values of wood are shown, which today cannot be quantified sufficiently in LCA (e.g. relations between forest management and multi-functional values of forests, sustainable reproduction of wood, careful and benign harvesting practices, CO[sub 2] cycling with wood, and  More>>

The report's second part summarizes the results of an environmental assessment of wood as a raw material and construction component, and of some important wood-based products. First, some product-independent ecological values of wood are shown, which today cannot be quantified sufficiently in LCA (e.g. relations between forest management and multi-functional values of forests, sustainable reproduction of wood, careful and benign harvesting practices, CO[sub 2] cycling with wood, and the complete utilization of the resource for industrial productions). Although all these basic characteristics contribute to the out-standing ecologic value of wood, an environmental analysis has to concentrate on material- and product-related aspects. In our study, this is realized by assessing energy consumption and air pollution. In a case study the data compiled are used to compare a timber frame wall with several wall types of different materials, but with identical heat transmission and acoustic performance: as expected, the timber frame wall shows very good ratings.
