The International Symposium on Life Cycle Assessment and Construction was co-organized at La Cité Nantes Events Center in Nantes, France, on 10-12 July 2012, by IFSTTAR (the French Institute for Transports, Development and Networks, formerly LCPC) and CSTB (the French Scientific and Technical Center for Buildings), under the scientific auspices of 3 international organizations: RILEM (the International Union of Laboratories and Experts in construction Materials, systems and structures), ISIE (the International Society for Industrial Ecology), and SETAC (Society of Environmental Toxicology And Chemistry).
It was also encouraged by EcoSD (the French network of researchers and industrials in eco-design), and LiRGeC (the Nantes regional network of researchers in civil engineering).

The symposium benefited from the institutional partnerships of the French Ministry for Ecology, Sustainable Development and Energy, the Pays de la Loire Region, and Nantes Métropole. The symposium was also sponsored by Bouygues construction, Lafarge, Cycleco, Cimbéton and Pwc.

Three keynote lecturers were invited: Pr Jeroen Guinée (University of Leiden, The Netherlands), Pr Arpad Horvath (University of Berkeley, USA) and Pr Niklaus Kohler (Karlsruhe Institute of Technology, Germany).

The scientific program of the two first days included 41 presentations in the following session topics:


Scientific presentations from the first 2 days were issued at 69% from academics, at 22% from private companies (industriels, professional organizations, consulting) and at 8% from institutionals (ministries, local authorities).


A poster session was also organized with 20 posters.

The third day of the symposium was dedicated to exchanges between researchers and practitioners through invited presentations and round tables.

165 participants from 27 different countries have attended the symposium: Australia, Austria, Belgium, Brazil, Cameroon, Canada, Croatia, Czech Republic, Denmark, Finland, France, Germany, Hungary, India, Ireland, Italy, Israel, Luxemburg, Malaysia, The Netherlands, Nigeria, Portugal, Spain, Sweden, Switzerland, United Kingdom and USA.

Participants were issued at 38% from academics, at 49% from private companies (industriels, professional organizations, consulting) and at 10% from institutionals (ministries, local authorities).

The best article award was delivered by the scientific committee and sponsored by Bouygues construction to Mrs Sarah E. Horvath and Zsuzsa Szalay from the Department of Building Constructions, Faculty of Architecture in Budapest University, for their article entitled Decision-making case study for retrofit of high-rise concrete buildings based on life cycle assessment scenarios.

The proceedings of the symposium will be freely available on the RILEM website in October.

The presentations of the scientific sessions and those of the exchanges between researchers and practitioners are available on the symposium website.

The numerous and enthusiastic returns from the participants and keynote lecturers encourage thinking about a second edition in a few years. The organising committee would be happy to help for a future organization. Please contact Anne Ventura.
