5 EPD Smartfacade LCA information Functional unit / declared unit: The declared unit is 1 m2 of Glass Mineral Wool faced Smartfacade with a thickness of 100 mm. The declared lambda is 0.032 W/mK at 10°C. The density used for the calculation of this specific LCA is 38 kg/m³. Reference service life: The RSL or durability of Smartfacade is as long as the lifetime of the building equipment in which it is used (at least 50 years). Time representativeness: Plants production data for the complete year 2019. Database(s) and LCA software used: The LCA model, the data aggregation and environmental impacts are calculated with the software GaBi 10.0 and its Service Pack 40 databases. System diagram: Description of system boundaries: The system boundary of the EPD follows the modularity approach defined by the /EN 15804+A1/. The type of EPD is cradle-to-grave. List and explanation of the modules declared in the EPD. The product stage (A1-A3) includes: - A1 - raw material extraction and processing, processing of secondary material input (e.g. recycling processes), - A2 - transport to the manufacturer and - A3 - manufacturing. This includes provision of all materials, products and energy, packaging processing and its transport, as well as waste processing up to the end-of-waste state or disposal of final residues during the product stage. The LCA results are given in an aggregated form for the product stage, meaning that the modules A1, A2 and A3 are considered as a unique module A1-A3. Product Parameters Value Declared Density 38 kg/m³ Glass mineral wool weigth (without facing weight) 3.8 kg Surface 1 m² Thickness 100 mm Volume 0.1 m3 Facing 0.125 kg Packaging Plastic sheet 0.083 kg Packaging Wooden pallet 0.21 kg The construction process stage includes: - A4 - transport to the construction site and - A5 - installation into the building. The transport to the building site (A4) and installation (A5) included in this LCA use the following parameters: Parameter Value Average transport distance (truck) 600 km Type of fuel and vehicle consumption or type of vehicle used for transport. Truck Euro 6 (28 – 32 t / 22 t) Fuel Consumption 33 L/ 100 km. Truck capacity utilization (including 30% of empty returns) 24 % of the weight capacity Average transport distance (boat) 17700 km Type of fuel and type of vehicle used for transport (boat) Container ship (5000 to 200000 dwt payload capacity) Loss of materials in construction site 2% Packaging Wooden pallet 40% recycled, 60% incinerated Packaging Plastic sheet 40% recycled, 60% incinerated
6 EPD Smartfacade The treatment of the packaging waste after the installation of the product (A5) has been considered. The Use stage (B1-B7) includes: - B1: Use - B2: Maintenance - B3: Repair - B4: Replacement - B5: Refurbishment - B6: Operational Energy Use - B7: Operational Water Use Once installation is complete, no actions or technical operations are required during the use stages until the end of life. Therefore, the mineral wool has no impacts (excluding potential energy savings) on this stage. The end-of-life stage includes: - C1 - de-construction, demolition, - C2 - transport to waste processing, - C3 - waste processing for reuse, recovery and/or recycling and - C4 - disposal. This includes provision of all transports, materials, products and related energy and water use. The common manual dismantling impact of insulation is considered as very small and can be neglected in C1. Although Glass Mineral Wool products from Knauf Insulation are partly recycled at their end-of-life, an established collection system does not yet exist. Therefore, the assumption chosen in this study, 100% landfill (C4) after the use phase, is the most conservative approach. Parameter Value Disposal type (mineral wool) 100% landfill Average transport distance waste (C2) 50 km Type of fuel and vehicle consumption or type of vehicle used for transport. Truck-trailer, Euro 3, 34 - 40t gross weight / 27t payload capacity/ 40 L for 100 km. (if 100 % utilization). Truck capacity utilization 50 % of the weight capacity Module D includes reuse, recovery and/or recycling potentials. According to /EN 15804+A1/, any declared benefits and loads from net flows leaving the product system not allocated as co-products and having passed the end-of waste state shall be included in module D. Benefits considered in module D originate from packaging recycling or incineration. Content Declaration The product does not contain substances on the "Candidate List of Substances of Very High Concern for Authorisation" under the REACH regulation (if above 0.1% of the mass). Recycled material The mineral wool waste that is originating from the manufacturing process in the cutting lines is recycled internally and reinjected into the mineral wool production mattress. For 2019 year, cullet external waste is considered into this specific LCA for each plant considered. Recycled content for this product was calculated at 61 % in 2019 according to the cullet market availability. Additional information: All raw materials for the manufacturing of the declared product, the required energy, water consumption and the resulting emissions are considered into the LCA. Consecutively, the recipe components with a share even less than 1% are included. All neglected processes contribute less than 5% to the total mass or less than 5% to the total energy consumption. For information, the impact of the Glass Mineral Wool plant construction or machines is not taken into account in the life cycle assessment. Allocation criteria with by-products (mineral wool for ceiling tiles) are based on cost. Knauf Insulation adopts a “worst case” approach into its EPDs.

12 EPD Smartfacade LCA interpretation ENVIRONMENTAL IMPACTS All impact categories except the ADPE and the ODP are dominated by the manufacturing. This is mainly due to the consumption of energy (electricity and natural gas) during the production of glass mineral wool. The Global Warming Potential (GWP) is clearly dominated by the production, mostly due to energy consumption (electricity and natural gas). The high cullet content is helping to reduce the energy use in the melting furnace. The Ozone layer Depletion Potential (ODP) seems highly influenced by the installation step, mostly due to plastics packaging incineration scenario resulting in emissions of halogenated compounds. The Acidification Potential (AP) is also dominated by the production due to the process’s emissions and the electricity consumption. Most of impact is by emissions of sulphur dioxide, ammonia and nitrogen oxides. The Eutrophication Potential (EP) is significantly influenced by the manufacturing due to emissions from curing oven, furnace and other unit processes. The glucose for the binder production also has an impact because of crops fertilizers use. The Photochemical Ozone Creation Potential (POCP) is dominated by the production due to emissions in the curing oven and in other unit processes but also energy consumption. The Abiotic Depletion Potential Element (ADPe) is dominated by the raw materials production. The Abiotic Depletion Potential Fossil (ADPf) is dominated by natural gas use and the electricity consumption for the production. The packaging and the binder have also a non-negligible impact. The installation stage has a “positive” contribution due to the energy recovery from incineration of a percentage of plastic packaging and the avoidance production of new plastic production thanks to a percentage of recycling plastic packaging. RESOURCES USE Total Use of Non-Renewable Primary Energy Resources (PENRT) is dominated by the manufacturing of glass mineral wool products (especially due to the energy consumption) and with the little influence of raw materials and packaging. Total Use of Renewable Primary Energy Resources (PERT) is dominated by the binder (bio-based), the production, (electricity mix) and the packaging (wooden pallets). For the Use of Secondary Material (SM), there is a lot of external cullet used into the batch process (recycled glass from windows and bottles) up to 80% depending on plants
