As such, the geographical coverage for this study is based on United States system boundaries for all processes and products. Whenever US background data were not readily available, European data or global data were used as proxies.The main material input into the YKK AP manufacturing process is aluminum ingot. The ingot is first alloyed to the desired grade and cast into billets. Subsequently, the billets are extruded into profiles using steel dies that are manufactured on-site. The extruded profiles may then be anodized or painted. Optional thermal treatment, whereby a system is thermally broken, leads into the product’s fabrication and assembly. In a last step, the complete assemblies are packed for shipment.Window wall systems are commonly used in ribbon window configurations or punched openigns. THe framing system spans from slab-to-slabe and can be installed formt he building's interior for logistics and installation. Window wall systems can also employ floor slab edge covers that enable the system to mimic the look of a cuertain wall system at a reduced cost.epd_ykk america.pngPartly terminated systemAttributionalnoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentAllocation - massAs required by EN 15804, in case of insufficient input data or data gaps for a unit process, the cut-off criteria were 1% of renewable and non-renewable primary energy usage and 1% of the total mass input of that unit process. The total of
neglected input flows per module was a maximum of 5% of energy usage and mass.
In practice, all inputs and outputs, for which data are available, have been included in the calculation. Data gaps have been filled by conservative assumptions with average or generic data. Capital items for the production processes
(machines, buildings, etc.) were not taken into consideration.Environmental Product Declaration - Aluminum Window Wall Systems95.02014No statementSphera Solutions GmbHSphera Solutions GmbH2021-02-01T00:00:00.000ILCD format 1.1Sphera Solutions GmbHNo official approval by producer or operator2021-02-01T00:00:00.00000.00.001Data set finalised; entirely publishedGaBi databasesSphera Solutions GmbHtrueOtherThe EPD owner has agreed to add LCI information corresponding to the EPD to the GaBi databases.
