  • Environmental product declarations entering the building sector: critical reflections based on 5 to 10 years experience in different European countries
    The International Journal of Life Cycle Assessment, 2015
    Co-Authors: Alexander Passer, Bastian Wittstock, Dieter Lathauwer, Carolin Spirinckx, Johannes Wall, F Gschosser, Sébastien Lasvaux, Karen Allacker, Daniel Kellenberger, Holger Wallbaum
    Abstract:

    PurposeGrowing awareness of the environmental performance of Construction Products and buildings brings about the need for a suitable method to assess their environmental performance. Life cycle assessment (LCA) has become a widely recognised and accepted method to assess the burdens and impacts throughout the life cycle. This LCA-based information may be in the form of environmental product declarations (EPD) or product environmental footprints (PEF), based on reliable and verifiable information. All of these use LCA to quantify and report several environmental impact categories and may also provide additional information. To better understand on the one hand existing EPD programmes (EN 15804) for each country and on the other the recent developments in terms of EU reference document (e.g. PEF), the authors decided to write this review paper based on the outcomes of the EPD workshop that was held prior to SB13 Graz conference.MethodsThis paper presents the state of the art in LCA and an overview of the EPD programmes in five European countries (Austria, Belgium, France, Germany, Switzerland) based on the workshop in the first part and a comprehensive description and comparison of the PEF method and EN 15804 in the second part. In the last part, a general conclusion will wrap up the findings and results will provide a further outlook on future activities.Results and discussionThe high number of EPD programmes underlines the fact that there is obviously a demand for assessments of the environmental performance of Construction materials. In the comparison between and experiences of the different countries, it can be seen that more similarities than differences exist. A comparison between PEF and EPD shows differences, e.g. LCIA impact categories and recycling methodology.ConclusionsIndependent of raising awareness of the Construction material environmental performance, the existence of so many environmental claims calls for clarification and harmonisation. Additionally, Construction materials being assessed in the voluntary approaches have to follow the harmonised approach following the principles of the European Construction Products Regulation (regulated) not to foster barriers of trade. The authors therefore highly appreciate the most recent activities of the sustainability of Construction works (CEN/TC 350 committee http://portailgroupe.afnor.fr/public_espacenormalisation/CENTC350/index.html ) currently working on these issues at the EU level. Finally, the LCA community is further encouraged to increase the background life cycle inventory data and life cycle inventory modelling as well as the meaningfulness of certain environmental impact categories, such as toxicity, land use, biodiversity and resource usage.

  • Sustainable Potential of Textile-Reinforced Concrete
    Journal of Materials in Civil Engineering, 2015
    Co-Authors: Natalie Williams Portal, Holger Wallbaum, Karin Lundgren, Katarina Malaga
    Abstract:

    The building Construction industry is in need of sustainable materials and solutions. A novel building material, such as textile-reinforced concrete (TRC), could be used to meet this demand. TRC is a combination of fine-grained concrete and multi-axial textile fabrics, which has been fundamentally researched over the past decade. TRC-based research has explored various facets of this composite material, such as its structural functionality, production, applicability and design. One key aspect that is still missing, however, is a comprehensive review of the sustainable potential of this material in terms of its input-output and durability which suitably answers to requirement no.7 of EU’s Construction Products Regulation. This article provides qualitative and quantitative evaluation of the sustainable potential and prospective development of TRC particularly reinforced by alkali-resistant (AR) glass, carbon or basalt fibers. Based on the outcome of this evaluation, carbon textile fibers were observed to hold the optimal potential mechanical behavior; additionally, it was revealed through the conducted Life Cycle Assessment (LCA), that basalt had the least cumulative energy demand while carbon had the least environmental impact.
