abb7dabe-e522-42e9-a120-3ad56b8a4433Traditional aluminum curtain wall (A1-A3) [Kawneer Co. Inc.]Cradle-to-gate production of traditional aluminum curtain wall systemssingle route, at plant1.5m x 1.6m; frame-to-glazing ration of 21.9% to 78.1% by massSystemsConstructionThis dataset for traditional aluminum curtain walls, produced by Kawneer, come from four U.S. plants: Bloomsburg, PA; Cranberry, PA; Springdale, AR; Visalia, CA; and a Candian plant in Lethbridge, AB.0Primary data were collected from four facilities in the U.S. and one in Canada with seasonal variations accounted for by collecting 12 months-worth of data. US-specific background data were used whenever possible.The manufacturing process and end product is essentially the same in all manufacturing sites. Float glass is insulated, laminated, or tempered and added to the finished assembly. At this time data does not include
granularity to differentiate between insulate, laminated and tempered glass. As such, all glass is treated the same.
Glass is only processed at the Cranberry facility. The remaining facilities produce and sell only the aluminum frames.
For these facilities, the glass produced at the Cranberry facility was used as a proxy for the window glazing.
No significant assumptions have been made beyond the aforementioned. All of the raw materials and energy inputs
have been modeled using processes and flows that closely follow actual production raw materials and processes. All
of the material and energy flows have been accounted.Curtain walls acts as outer layers to keep out water and hold glass, and can also offer thermal protection, blast mitigation, hurricane resistance, and day lighting.kawneer - traditional curtain wall.pngLCI resultAttributionalnoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentAllocation - massDirect land use change: GHG emissions from direct LUC allocated to good/service for 20 years after the LUC occurs.
Carbon storage and delayed emissions: credits associated with temporary (carbon) storage or delayed emissions are not considered in the calculation of the Global Warming Potential impacts for the default impact categories.
Emissions off-setting: not included
Fossil and biogenic carbon emissions and removals: removals and emissions are modelled as follows: All GHG emissions from fossil fuels (including peat and limestone) are modelled consistently with the ILCD list of elementary flows. In the case that the emissions refer to the molecules CO2 and CH4, they are modelled as ‘carbon dioxide (fossil)’ and ‘methane (fossil)’. Biogenic uptake and emissions are modelled separately. For land use change, all carbon emissions and uptakes are inventoried separately for each of the elementary flows. Soil carbon accumulation (uptake) via improved agricultural management is excluded from the model.NoneAs 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.NoneAll relevant background data such as energy and auxiliary material are taken from the GaBi Databases, keeping consistency.NoneFor details please see the document "GaBi Databases Modelling Principles"NoneEnvironmental Product Declaration - Traditional curtain wall95.02014NoneThe data set represents a cradle to gate inventory. It can be used to characterise the supply chain situation of the respective commodity in a representative manner. Combination with individual unit processes using this commodity enables the generation of user-specific (product) LCAs.All relevant flows quantifiedThe LCI method applied is in compliance with ISO 14040 and 14044. The documentation includes all relevant information in view of the data quality and scope of the application of the respective LCI result / data set. The dataset represents the state-of-the-art in view of the referenced functional unit.Sphera Solutions GmbHOverall quality according to different validation schemes
GaBi = 1,3 interpreted into "very good overall quality" in the GaBi quality validation scheme
The EPD has been verified by an indipendent reviewer, who was organized by the IBU.IBUSphera Solutions GmbHThis EPD dataset represents the specific product, producer and phase of the life cycle incated in the name of the data set. Basically, an evaluation of EPD data is only possible if all the data sets to be compared were created according to EN 15804 and the building context, respectively the product-specific characteristics of performance, are taken into account.Sphera Solutions GmbH2022-03-01T00:00:00.000ILCD format 1.1Sphera Solutions GmbH2022-03-01T00:00:00.00000.00.001Data set finalised; entirely publishedSphera Solutions GmbHtrueOtherThe EPD owner has agreed to add LCI information corresponding to the EPD to the GaBi databases.
