4 EPD Urbanscape® Green Roof System Product information Product name: Urbanscape® Green Roof System Product description: The Urbanscape® Green Roof System is an innovative, lightweight, low-thickness, extensive greening system with a high-water retention capacity. It consists of a mix of three layers. Starting at the top, a layer of Urbanscape® Sedum vegetation in the form of pre-cultivated rolls comprising up to 12 different sedum species. The sebaceous sedum plants are adept at storing water in their leaves and are therefore extremely suitable for varying weather conditions. The mix of different species provides a diverse leaves and flowers dense cover throughout the year. Next, an Urbanscape® Green Roll growing media of needle-punched, binder-free rock mineral wool that provides both good rooting of the sedum mat and excellent water retention. The Green Roll can be of different thicknesses but the most common is the 40 mm thickness which has been selected for this life cycle assessment calculation. Finally, a drainage layer Urbanscape® Drainmat which guarantees high water discharge capacity. The drainage layer is a three-dimensional, light and flexible composite matting made up of a drainage core of looped polypropylene filaments, which gives it a high drainage capacity, provided on both sides with a nonwoven filter fabric. Urbanscape® Drainmat is a high-performance CE-marked drainage system made of 100 % recyclable polypropylene. If needed, depending on the roof quality, an additional root barrier membrane can be added underneath the system (but this is not part of this study). This kind of green roof is defined as instant green roof as vegetation is covering at least 95% of substrate media directly at installation. Application: The Urbanscape® Green Roof System is an innovative, lightweight, low-thickness, extensive vegetation system with a high-water retention capacity. It can be installed on terraces and inaccessible roofs with a slope of 20% or less on residential, non-residential, and industrial buildings in urban areas. It is suitable for all types of load-bearing elements -
5 EPD Urbanscape® Green Roof System concrete, steel, wood - in new construction as well as in renovation. Production process: The Urbanscape® Green Roof System is made of three different layers. The sedum-blanket is composed up to 12 different species of sedums and it boasts at least 95 % coverage upon delivery. The Sedum-mix blanket is cultivated in the Netherlands in open fields to allow further extensive use on the roofs. The growing media is made of binder-free rock mineral wool manufactured by Knauf Insulation in Škofja Loka (Slovenia). Main raw materials used in the production of mineral wool are diabase (a rock that is similar to volcanic rock basalt), dolomite and briquettes (briquettes made mainly of recycled mineral wool reintroduced in the melting process). For these first two layers, specific manufacturing data was used. The drainage system, made of 100% recyclable polypropylene, is manufactured in Italy. The production of the layer was approximated as an injection moulding process. Technical data: The Urbanscape® Green Roof System meets several technical requirements. The most important ones are summarized in the table here below. Name Value Unit Water storage capacity 37 Vol. -% System sound absorption (/EN ISO 10140-1 // EN ISO 10140-2) 57 dB System height 100 mm System weight saturated 57.55 kg/m² System weight unsaturated (dry) 20.55 kg/m² Retenton (System maximum water retention capacity) 37 l/m² pH value of the growing media (CaCl2) 7.5 Fire resistance class for growing media (EN 13501-1) A1 Salt content of the growing media (KCl) 0.03 g/l LCA information Functional unit / declared unit The declared unit is 1 m² of Urbanscape® Green Roof System including the 3 components sedum-blanket, Green roll and drainage layer. Potential root barrier, protection layer or waterproof membrane are not considered into this specific EPD as those additional layers depends on the existing roof quality. However, the quality of the roof should be most of the time sufficient to avoir adding any additional layers to the 3 proposed components of the Urbanscape® system. Geographical scope: The RMW layer of the product is manufactured in Škofja Loka (Slovenia) with the related country energy mix for electricity. The Sedum layer is supplied from the Netherlands and the drainage layer in Italy. Regarding the market area, the product is mainly marketed in Europe, therefore the use phase and end of life scenario are modelled as European. Energy: Regional electricity mix and gas inputs were used in modelling raw material production, taking datasets from Slovenia and Italy, both with reference year 2017 (the latest available in GaBi database). 0.365 kg of CO2 eq. is released for 1 kWh of Electricity consumption from Slovenia and 0.452 kg of CO2 eq. for Italy. Reference service life: The Reference Service Life (RSL) or durability of Urbanscape® Green Roof can be with proper maintenance as long as the lifetime of the roof on which it is installed. The scenario selected in this EPD is 50 years. Time representativeness & Information on Specific Data: All primary and secondary data is modelled to be specific to the technologies or combinations of technologies under consideration. When technology-specific data is not available, proxy data is used. The technological representativeness is good. All primary data is collected for the year 2020. All secondary data comes from the GaBi 2021
6 EPD Urbanscape® Green Roof System databases and is representative of the years 2015-2020. As the study aimed to compare the product systems for the reference year 2020/2021, the temporal representativeness is good. Database(s) and LCA software used: The LCA model, the data aggregation and environmental impacts are calculated with the software GaBi 10. Background databases are GaBi datasets with last update 2021. The impact models used are those indicated in EN 15804:2012+A2:2019. System diagram: The diagram illustrates the life cycle stages of construction products in general. The system boundaries starts with the raw materials for the production of the three layers of the Urbanscape® System. These are manufactured separately before being assembled. It must be noted that for A1-A3 stage, the Urbanscape® Sedum vegetation (production of the seeds is outside of the system boundaries) and the Urbanscape® Green Roll growing media (binder-free rock mineral wool) are modelled with specific data. The drainage layer Urbanscape® Drainmat production was approximated as an injection moulding process. Description of system boundaries: The system boundary of the EPD follows the modularity approach defined by the EN 15804:2012+A2:2019. 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. 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 900 km Type of fuel and vehicle consumption or type of vehicle used for transport. Truck Euro 6 (34 – 40 t / 27 t payload). 140 L for 100 km. Truck capacity utilization (including 30% of empty returns) 61 % of the weight capacity Loss of materials in construction site 2% Packaging Wooden pallet 40% recycled, 60% incinerated Packaging Plastic sheet 40% recycled, 60% incinerated 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 For the B1 use stage, carbon sequestration is included in this study. The CO2 sequestered by the sedums during their 50 years life will be released by composting the materials at the end of their life.
7 EPD Urbanscape® Green Roof System For the maintenance stage (B2), fertilisation in the first year is recommended and included in this study. Thereafter, the green roof can be fertilised in subsequent years if required. In this study, fertilisation every 5 years is considered, reflecting actual practice. Stages B3 (repair), B4 (replacement) and B5 (renovation) the Urbanscape® product has no impact as the system is considered to be self-maintaining. The green roof system lives very well on its own, but to maintain an installation, one annual visit to remove weeds is recommended: there is always some colonisation of native plants by air. This is not a bad thing as it provides additional biodiversity; however, some plants can be too invasive and must be removed to ensure the resilience of the installation. This maintenance is done manually. If maintenance is carried out correctly, there is no reason to replace the plant cover. Sedum has a strong ability to recolonise empty spaces if they exist. If necessary, plants can be taken from landscaped areas and redistributed where they are lacking; they take root very easily. A sedum fragment will naturally re-root to become an independent plant. The stage of use (B6-B7) relating to the operation of the building has no impact on the Urbanscape® product. For B7, operational use of water, for very specific weather conditions, it may be useful to provide water punctually. These specific case studies are not analysed in this study. 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 green roof is considered as very small and can be neglected in C1. At the end-of-life, it is assumed that the sedum-blanket and the Green roll are composted (100%), the drainage layer in polypropylene is recycled (20 %) and incinerated (80 %). Module D includes reuse, recovery and/or recycling potentials. According to EN 15804:2012+A2:2019 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 the incineration and recycling of packaging materials as well as the recycling and incineration of the drainage layer. Additional information: All raw materials for the manufacturing of the layer of rock mineral wool 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 Rock Mineral Wool plant construction or machines, are not taken into account in the life cycle assessment. Materials for fixation and installation are not included into this LCA scope. Regarding installation this EPD only includes the environmental impact related to the product itself like material losses and packaging end of life. This may lead to the need of additional construction products or materials for which the impact is not included in this EPD and which shall be taken into account at building level. Knauf Insulation adopts a “worst case” approach into its EPDs.

13 EPD Urbanscape® Green Roof System LCA interpretation ENVIRONMENTAL IMPACTS The production of the mineral wool is the main contributor to the environmental impacts, mainly due to the energy consumption during production (e.g., electricity…). The sedum-blanket made of renewable materials and the drainage layer have smaller impacts. The Global Warming Potential (GWP) impact main contributor is the production of mineral wool using coke which has a high CO2 emission factor. The sedum layer is a major contributor the GWP impacts, during the production of the sedum and the use phase (50 years), the plants will sequester up to 61.5kg of CO2. This CO2 will then be released at the end of life through the composting of the layer. The incineration of the packaging (wooden pallet and plastic foils) at installation and the end of life of the polypropylene drainage layer has an impact in modules A5 and C2. The benefits from the energy generated via the incineration of a proportion of the packaging and the drainage layer is accounted in the module D. The Ozone layer Depletion Potential (ODP) results are mostly impacted by the plastic sheets (packaging) incineration. The Acidification Potential (AP) is also dominated by the manufacturing of rock mineral wool due to the emissions related to the processes and the energy consumption. The Eutrophication Potential (EP) is significantly influenced by the manufacturing of rock mineral wool due to emissions from cupola furnace, curing oven and other unit processes. The Photochemical Ozone Creation Potential (POCP) is particularly dominated by the manufacturing of rock mineral wool (emissions in the cupola furnace and other unit processes). The Abiotic Depletion Potential Minerals&metals (ADPmm) main impacts are coming from the production of the mineral wool (>50% of total impacts are due to the use of cement in briquettes for recycled materials) The Abiotic Depletion Potential Fossil (ADPf) is dominated by the use of the energy mix (electricity and other sources). There are also originating from the production of the drainmat which is made of polypropylene. USE OF ENERGY RESOURCES The primary energy demand from non-renewable resources is dominated by the production of the green roll made of mineral wool (especially due to the energy consumption). The renewable energy demand is also dominated by the production, mostly due to electricity consumption, and packaging.
