LCA: Calculation rules3.1 Declared UnitThe declared unit is 1 piece of a manually operated VELUX flatroof window CXP with a base unit made of a PVC curb with anintegrated glazing unit with 1.20 m x 1.20 m = 1.44 m2.Declared unitNameValueUnitDeclared unit1pieceArea1.44m2Weight88,1kg 3.2 System boundaryType of EPD: Cradle to gate with options, with modules C1 –C4, and module D (A1-A3, C1-C3, D and additional modulesThe production of VELUX flat roof windows (modules A1-A3)includes raw material extraction, energy generation, wastetreatment and all transports up to the factory gate. Inaccordance with COUNCIL REGULATION (EU) No 333/2011,secondary metals are modeled as part of the product systemfrom the moment they are available as unmixed scrap.Waste or secondary fuels are not used for production.Module A4 is not declared due to large variances in transportdistances between the production site and the construction site,where the product is installed.Module A5: The products are delivered to the construction siteready to be installed. Manual installation is assumed; electricityconsumption related to electric drilling machines, screw drivers,etc. is considered to be negligible. The combustible packagingmaterial (plastics, wood, etc.) is assumed to be thermallytreated in a municipal waste incineration plant with an efficiencyR1 < 0.6 (according to the ecoinvent dataset used); therecovered energy is declared as exported energy. Metals andcardboard are recycled; it is assumed that these fractions reachthe end-of-waste state after having been sorted andtransported (as a conservative choice) to a recycler. Nopackaging waste is landfilled.Environmental Product Declaration - VELUX A/S - VELUX flat roof window CXP3

Modules B1 to B7 are not relevant for the product underconsideration or no significant environmental impacts occur.Module C1 includes manual dismantling, with no significantenvironmental impact.Module C2 comprises the transport of the dismantled VELUXflat roof window to a sorting plant and then to a wasteincineration plant for the thermally treated plastic fraction.Modules C3/C4: given the complexity of the inventoriedproducts, a mixed end-of-life scenario is modelled, allowing thedifferent materials to follow their most likely path.As a rule of thumb, metals are recycled and plastics areincinerated (also due to the very limited data availability ofplastics recycling and its benefits); coated and uncoated flatglass is assumed to be recycled whereas laminated glass isassumed to be landfilled due to very limited recycling potential.Metals and flat glass recycled; it is assumed that these fractionsreach the end-of-waste state after having been sorted andtransported to a recycler; laminated glass is landfilled. Thecombustible material (plastics, etc.) is assumed to be thermallytreated in a municipal waste incineration plant.Module D includes the benefits and burdens associated withrecycling metals beyond the system boundary, resulting fromthe treatment of recycled materials from the point of end-of-waste to the point of substitution (as loads) and substitution ofprimary resources (as benefits).It also includes the benefits and burdens associated withenergy recovery from plastic waste in a municipal wasteincineration plant, as modeled in Module C3.In Module D, only net flows of metals leaving the productsystem are considered.3.3 Estimates and assumptionsNo further assumptions and estimates relevant to the result hadto be made beyond the points made in this chapter 3 and inchapter 4.3.4 Cut-off criteriaNo data available from the company survey was neglected.These include, among other things, material use, energydemand (heat, electricity), packaging materials of raw materials(insofar as they are generated as waste) and productpackaging, consumables in production, waste treatment andthe transport of all inputs and outputs.With this approach, mass and energy flows below 1 % werealso accounted for. No processes were neglected that wouldhave been known to the project managers and would havecontributed significantly to the indicators of the impactassessment.3.5 Background dataEcoinvent 3.8 (2021) is used as the background database.3.6 Data qualityThe foreground data are based on extensive and detailed datacollection at the production site. The foreground data could befully linked with corresponding data records from thebackground database ecoinvent 3.8.The background data was updated in 2021. Thus, the quality ofthe foreground and background data can be rated as verygood.3.7 Period under reviewThe LCA data represents the production conditions for the year2021.3.8 Geographic RepresentativenessLand or region, in which the declared product system ismanufactured, used or handled at the end of the product´slifespan: Europe3.9 AllocationNo co-products are generated during the production of theVELUX products. Sorted production scrap of the differentmetals, notably aluminium, is considered a secondary materialwith no economic value (so no burdens allocated) andconsidered in the quantification of net flows leaving the productsystem. This approach is chosen to ensure a coherentquantification of net flows entering module D.No processes were modelled as part of the foreground modelthat would have required an allocation of multi-input processes.Background datasets on municipal waste incineration plantswere taken from ecoinvent without any modification.Allocation of reuse, recycling and recovery was avoided by thecut-off approach in the foreground model in line with DIN EN15804.3.10 ComparabilityBasically, a comparison or an evaluation of EPD data is onlypossible if all the data sets to be compared were createdaccording to EN 15804 and the building context, respectivelythe product-specific characteristics of performance, are takeninto account. 4.

They aremaintained by cleaning waterat the discretion of thebuilding occupants.-Module B1The products are assumed to have no direct emissions duringthe use phase. The indicator values of Module B1 are thus 0.For biogenic carbon storage, see table above.Module B2For manually operated flat roof windows, no impacts related tomaintenance are inventoried in module B2. Annual cleaningwith water (e.g., using 1 l/m2 of tap water per annual cleaning)is neglected.Module B6Manually operated flat roof windows do not consumeoperational energy.Module C1Manual de-installation is assumed, electricity consumptionrelated to electric screw drivers, etc. is considered to benegligible. Thus, no environmental impacts are declared inmodule C1.Module C2Given the complexity of the inventoried products, a mixed end-of-life scenario is modelled, allowing the different materials tofollow their most likely path.It should also be noted that the deconstruction and wastetreatment scenario can vary a lot, depending on the actualsituation. Thus, a generic end-of-life scenario is assumed.As a rule of thumb, metals are recycled, plastics are incinerated(also due to the very limited availability on plastics recyclingand its benefits); coated and uncoated flat glass is assumed tobe recycled whereas laminated glass is assumed to belandfilled due to very limited recycling potential.The combustible material (mainly plastics) is assumed to betransported 50 km with a lorry 16-32 metric tons, EURO6 to anincineration plant.Metals and flat glass recycled; it is assumed that these fractionsreach the end-of-waste state after having been sorted andtransported to a recycler over 150 km with a lorry 16-32 metrictons, EURO6.Laminated glass is landfilled, including a transport of 30 km witha lorry 16-32 metric tons, EURO6.Module C3A consumption of 0.03 kWh/kg of electricity for shredding andsorting and 0.437 MJ/kg of diesel fuel for internal logistics aretaken into account to disassemble the product. The recoveredmaterial leaves the product system as 'materials for recycling'.The net amounts of the metals leaving the product system areconsidered as 'use of secondary material' in Module D.Module C4As stated above, it is assumed that 100 % of the plastic partsand the wooden parts are treated in a waste incineration plantwith an efficiency R1 < 0.6 (according to the ecoinvent datasetused); 25.57 % of the lower heating value of the plastic partsare recovered as heat and 13.0 % as electricity. Recoveredenergy is reported as 'exported energy' and considered inModule D.Some of the material, notably laminated flat glass is assumedto be landfilled.Module DModule D contains the benefits and loads beyond the systemboundary related to the recycling of metals, which result fromthe treatment of recycled materials from the point of end-of-waste status to the point of substitution (as loads) and thesubstitution of primary resources (as benefits).Furthermore, it includes the benefits of raw material substitutionof the recycling of flat glass, with the exception of laminatedglass, which cannot be used for the production of glass again.Recovered flat glass is assumed to have reached the end-of-waste state as sorted glass cullet; glass cullet is assumed toreplace virgin raw material for glass production – impacts onthe energy required to remelt recycled glass as compared tovirgin glass production are neglected due to a lack of data.It also includes the benefits and loads related to the energyrecovery from plastic wastes in a MWIP as modelled inModules A3, A5 and C3.Due to a lack of data for plastics from de-construction activities,the substitution potential of recycled plastics is not taken intoaccount.Only net flows leaving the product system are considered inmodule D.Environmental Product Declaration - VELUX A/S - VELUX flat roof window CXP5

LCA: InterpretationFigure 1 illustrates the relative contributions of the differentmodules along the life cycle of the declared products.Figure1: Relative environmental impacts of the different lifecycle stages for the manually operated flat roof windowCXPThe largest part of environmental impacts – between 70 % andrather 100 % - is caused during production (modules A1-A3) ofthe flat roof window. No operational energy is used as the flatroof window cannot be opened.Benefits and burdens beyond the system boundary (module D)are in the order of 0 % to 40% of the impacts over the productlife cycle (modules A1-C4). [1] The use of renewable primaryenergy is mainly caused by the share of renewable energy inthe electricity mix, thus the production stage is the main driverof this impact category; also for the use of non-renewableprimary energy, the production phase is the most impacting lifecycle stage.Material use of primary energy is negligible and related toplastic parts of the product and packaging material.

material use of primary energy is transferred to its energy usewhen the materials containing primary energy are incineratedwith energy recovery.Non-hazardous waste as the quantitatively most relevant wasteflows is mainly caused during the production of the glass andduring disposal of the product; hazardous and radio-activewastes are mainly caused by the European electricity mix.[1] Benefits resulting from the recycling of plastics as well asfrom the recycling of the electronic parts are disregarded due tothe lack of data on the recycling processes and related to thedetailed composition of the electronic parts.7.
