History (1/2) : History (1/2) 1990 : EU Environmental labelling for insulation products First LCA done by Saint-Gobain for 12 European products 1994 : LCA for building materials French producers of building materials (AIMCC) create a working group 1996 : French HQE association Created to promote the High environmental Quality of buildings Back to content


History (2/2) : History (2/2) 2001 : AFNOR standard XP P 01 010-1 To harmonize requirements from architects and other building’s stakeholders Environmental and health data sheets for building materials 2003 : AFNOR standard XP P 01 020 Environmental and sanitary characteristics of buildings 2003 : first complete Environmental & Health data sheets Back to content


AFNOR experimental standards : AFNOR experimental standards Environmental quality of construction products (XP 01 010) Information concerning the environmental characteristics of construction products Part 1: Methodology and model of data declaration (April 2001) Part 2: Framework for exploiting the environmental characteristics for application to a given construction work (May 2002) Environmental and sanitary characteristics of buildings (draft – September 2003?) Back to content


AFNOR XP 01 010, Part 1 : AFNOR XP 01 010, Part 1 To provide objective information and to be used to assess the impacts of construction products. Covers all stages of life cycle. The data shall be qualified and explained have to be representative, shall go with by an indication of accuracy and, in any case, the source had to be provided. Defines the functional unit Defines the mass cut-off rule for inputs Proposes rules for modification of scenarios Back to content


AFNOR XP 01 010, Part 2 : AFNOR XP 01 010, Part 2 To characterize the contribution of products to environmental impacts of a given construction work. Indicates what information shall be retrieved from first part of standard. Main impacts are quantified Contribution of the product to health risk management, Resistance to biocides, thermal shocks, organoleptic properties, fitness for contact with drinking water Contribution of the product to comfort Back to content


How LCA have been done by Saint-Gobain Isover? : How LCA have been done by Saint-Gobain Isover? In collaboration with Ecobilan SA (PriceWaterHouseCooper) At the same time as other French producers Belonging to the French association of Glass fibers and rock wool producers : FILMM Data sources Isover LCA, 1993 Ecobilan SA databases Saint-Gobain Isover plants Suppliers Tools TEAM software from Ecobilan SA DEAM software from Ecobilan SA Specific software to generate table which can be directly used in the E&H data sheets Back to content


Functional unit : Functional unit Quantity of product and, if necessary, complementary products and distribution packing contained in FU on basis of Typical Life Duration of 50 years. 100 m2 of glass fiber roll which main function is thermal insulation (roof insulation): 220 kg of glass fiber 6.4 kg of Kraft paper 6.5 kg of asphalt 2.0 kg of polypropylene veil 0.5 kg of hot melt glue Packaging 5 kg of polyethylene These values can not be used as such.

Hypothesis (1/2) : Hypothesis (1/2) Final product transportation 223 km by truck (22.4 t), returning empty at 96% Waste on building site None End of life To landfill Electricity French model for production European model for all other stages of the LCA Input and output 99.8% have been taken into account Back to content


Hypothesis (2/2) : Hypothesis (2/2) Energy savings during use (done by TRIBU Energie) Back to content

What next? : What next? E&H data sheets are or will be soon available for the main building materials For the main Isover products, by the end of 2003 They will be certified by external auditor Comparison between products must be done very carefully Hypothesis are not always the same Functional units have to be the same!
