0b5ba5a8-1cca-495d-a32f-ddfb676c4aaaNon-reinforced ethylene propylene diene monome roofing membrane,45 mils (A5)- Carlisleindustry mixproduction mix (at plant)single ply roofing membrane thickness = 45 milsSystemsConstructionThis data set contains the results for the module A5 according to EN 15804. It includes the installation into the building during the construction of the building, including both the provision of all materials, products and energy as well as the complete treatment of waste or residual waste at the building stage. This information module also contains effects and aspects that are associated with losses at the building stage (e.g. waste treatment and disposal of waste and material losses as well as the transport thereof).
A comparison with other products is only allowed by a similar application in the building. In principle, a comparison or evaluation of EPD data is only possible if all the datasets are created to be compared to EN 15804 and the product-specific features are considered.231The dataset represents US specific situation, focusing on the main technologies and the legislative boundary conditionsForeground system:
The system boundaries comprise installation phase of the lifecycle of a single ply non-reinforced ethylene propylene diene monomer (EPDM) roofing memebrane of 45 mils nominal thickness, in the year 2014. The installation process involves installing the roofing membrane using a solvent-based low-VOC adhesive (open input in this process). This dataset is modelled according to the European Standard EN 15804 modules. The dataset represents installation in the US and also includes disposal of the steel pail and membrane waste produced from the installation process.
Background system:
Electricity: Electricity is modelled according to the individual country-specific situations. The country-specific modelling is achieved on multiple levels. Firstly, individual energy carrier specific power plants and plants for renewable energy sources are modelled according to the current national electricity grid mix. Modelling the electricity consumption mix includes transmission / distribution losses and the own use by energy producers (own consumption of power plants and "other" own consumption e.g. due to pumped storage hydro power etc.), as well as imported electricity. Secondly, the national emission and efficiency standards of the power plants are modelled as well as the share of electricity plants and combined heat and power plants (CHP). Thirdly, the country-specific energy carrier supply (share of imports and / or domestic supply) including the country-specific energy carrier properties (e.g. element and energy content) are accounted for. Fourthly, the exploration, mining/production, processing and transport processes of the energy carrier supply chains are modelled according to the specific situation of each electricity producing country. The different production and processing techniques (emissions and efficiencies) in the different energy producing countries are considered, e.g. different crude oil production technologies or different flaring rates at the oil platforms.
Thermal energy, process steam: The thermal energy and process steam supply is modelled according to the individual country-specific situation with regard to emission standards and considered energy carriers. The thermal energy and process steam are produced at heat plants. Efficiencies for thermal energy production are by definition 100% in relation to the corresponding energy carrier input. For process steam the efficiency ranges from 85%, 90% to 95%. The energy carriers used for the generation of thermal energy and process steam are modelled according to the specific import situation (see electricity above).
Transports: All relevant and known transport processes are included. Ocean-going and inland ship transport as well as rail, truck and pipeline transport of bulk commodities are considered.
Energy carriers: The energy carriers are modelled according to the specific supply situation (see electricity above).
Refinery products: Diesel fuel, gasoline, technical gases, fuel oils, lubricants and residues such as bitumen are modelled with a parameterised country-specific refinery model. The refinery model represents the current national standard in refining techniques (e.g. emission level, internal energy consumption, etc.) as well as the individual country-specific product output spectrum, which can be quite different from country to country. The supply of crude oil is modelled, again, according to the country-specific situation with the respective properties of the resources.Thermal energy from natural gasThermal energy from LPGTap water from groundwaterElectricity grid mix (East)Electricity grid mix (West)Natural gas mixLiquefied Petroleum Gas (LPG) (70% propane; 30% butane)Electricity grid mix (Texas)EPDM is an extremely durable synthetic rubber single-ply roofing membrane used worldwide in low-slope buildings (roof slope < 2:12). It is classified as a thermoset material and is available in both black and white. The most common low slope roof consists of a metal deck, then a layer of insulation; cover board (optional) and then the roof membrane.The roof membrane is glued directly to the insulation below.LCI resultAttributionalNoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentAllocation - massForeground system: Mass allocation was applied to report primary data.
Background system: For the combined heat and power production, allocation by exergetic content is applied. For the electricity generation and by-products, e.g. gypsum, allocation by market value is applied due to no common physical properties. Within the refinery allocation by net calorific value and mass is used. For the combined crude oil, natural gas and natural gas liquids production allocation by net calorific value is applied.

Average values are the ones used in the inventory. Primary data was collected by data questionnaires sent to each participating company. The GaBi ts software system was used for generating the model of the production and as the source of background LCA information. The average environmental burdens of the national power grid mix in the production countries are used in the model. In case of an independent steam or energy supply at the production site, additional data were collected and modeled in GaBi.NoneData was collected and treated to ensure the resulting inventory is representative of the SPRI industry avergae TPO (45 mils) memebrane production.
