Nordic Dome (Akrylovenlys) - 2 to 5 layer vaulted-pyramid

Environmental Impact

Product Details

Description

A versatile, cost-effective acrylic dome rooflight for industrial, office, and other public buildings, available in vaulted or pyramid profiles and installed at 0 to 25° pitch. Set in an aluminium frame with a built-in drip edge, it offers 2 to 5 layer acrylic glazing with a polycarbonate outer skin (5-layer only in vaulted), along with strong daylight transmission and, at higher layer counts, added sound insulation. Available as fixed, comfort-ventilated, or configured for smoke exhaust and fire ventilation per DS/EN12101-2, with dual-purpose (Re50) certification allowing daily comfort ventilation alongside fire safety use. This EPD represents acrylic dome rooflights with 2 to 5 layer glazing . Results for all variations are reported using the most conservative variant (Nordic Dome (Akrylovenlys) - 5 layer - vaulted) as the reference. This EPD represents only the Rooflight. See separate EPD for Upstands.

Comparison of the environmental performance of products usingEPD information shall be based on the product’s use and impacts at the building level, and therefore EPDs may not be used for comparability purposes whennot considering the whole building life cycle. EPD comparability is only possible when all stages of a life cycle have been considered. However, variations anddeviations are possible. Example of variations: Different LCA software and background LCI datasets may lead to differences results for upstream ordownstream of the life cycle stages declared.

Product Flow DiagramSoftware And DatabaseLCA Software:SimaPro v. 10.2LCI Foreground Database(s):Ecoinvent v. 3.9.1Cut-off by ClassificationLCI Background Database(s):Ecoinvent v. 3.9.1Cut-off by ClassificationA foreground LCI database is the database used to model the primary, site-specific data collected for this EPD. A background LCI database is the databaseused to model generic or non-specific data.Data QualityPrecision & CompletenessPrecision: Inventory data were directly measured, calculated, or conservatively estimated from primary sources using consistent units and QA checks.Background processes from ecoinvent v3 were adopted with their documented uncertainty/precision metadata where available, preserving atransparent record of data quality.Nordic Dome (Akrylovenlys) - 2 to 5 layer vaulted-pyramidVELUXPage 6 / 27

Completeness: The product system's mass balance and inventory completeness were thoroughly checked. Some exclusions were made in line with thePCR requirements, such as personnel impacts, R&D activities, business travel, and point-of-sale infrastructure. However, no data were intentionallyomitted.Consistency and ReproducibilityConsistency: Primary data for all modules were consistently gathered aiming at the highest level of detail possible. Background processes weremodeled mainly with the ecoinvent database. The same allocation rules, cut-off criteria, and impact assessment methods were applied throughout,ensuring methodological coherence and consistent data quality across the entire LCA model.Reproducibility: This study ensures reproducibility by providing comprehensive disclosure of input–output data, dataset choices, and modelingapproaches. A knowledgeable third party should be able to approximate the results using the same data and modeling methods.RepresentativenessTemporal: Primary data were collected for a 12-month period representing the 2025 calendar year to ensure the representativeness of post-consumercontent. Secondary data from the ecoinvent v3 database are typically representative of recent years.Geographical: Primary data represent VELUX's production facilities. Where applicable, differences in electric grid mix were considered usingappropriate secondary data. The use of country-specific data ensures high geographical representativeness, and proxy data were only used whencountry-specific data were unavailable.Technological: Both primary and secondary data were tailored to the specific technologies studied, ensuring high technological representativeness.Life Cycle Module DescriptionModules A1–A3: The LCA model covers the manufacture of raw materials and components for VELUX products (A1) which are then transported to VELUXfacilities by truck (A2). The manufacturing stage (A3) begins with receipt of these materials, which are bent, cut, welded, and assembled into finished flapsand skylight systems. When required, additional parts like DSL grids and electronic components for home-automation systems are custom-cut andassembled to order.Modules A4–A5: Once manufacture is completed, products are shipped to distribution centers and then to the end user by truck (A4). For installation (A5), a3% material installation loss was assumed. This module includes disposal of that waste and of the product packaging.Modules C1–C4 and D: At end of life (C1–C4), the product is assumed to be collected, and each waste stream (e.g., aluminum, glass, PVC) is handledseparately—landfilled, recycled, or incinerated with energy recovery. Loads and benefits beyond the system boundary are considered in Module D (e.g.,displacement of virgin materials and electricity).LCA DiscussionAllocation ProcedureAllocation of co-products was avoided, to the extent possible, based on the guidance given in ISO 14044:2006, 4.3, and in EN 15804+A2:2019. Energy useat the facility level was allocated by the amount of product produced. The manufacturing process does not consume water or generate wastewater or airemissions, other than those from fuel combustion. Solid waste was estimated using packaging masses and material losses and allocated following thepolluter pays principle.Cut-off ProcedureThe system boundary was defined based on relevance to the goal of the study. For the raw material (A1) and process related inputs (A3), all availableenergy and material flow data have been included in the model.Nordic Dome (Akrylovenlys) - 2 to 5 layer vaulted-pyramidVELUXPage 7 / 27

These materials are then transported tomanufacturing facilities in the EU where they are stored, processed, and combined to produce finished products. Notably, the product stage (stage 1) has thehighest impact contribution, mainly attributed to the environmental impacts associated with raw material manufacturing.Nordic Dome (Akrylovenlys) - 2 to 5 layer vaulted-pyramidVELUXPage 25 / 27

Given that the raw materials used in product manufacturing have a significant impact, exploration of opportunities to substitute these materials withalternatives that have a lower environmental impact. Additionally, consideration should be given to collaborating with suppliers who employ sustainablemanufacturing techniques or integrate more renewable energy into their production processes. Such initiatives can lead to more environmentally friendlyproducts and further enhance the sustainability of the products in this analysis.0%20%40%60%80%100%GWP-TotalEF 3.1GWP-BiogenicEF 3.1GWP-FossilEF 3.1GWP-LulucEF 3.1ODPEF 3.1APEF 3.1EP-FreshwaterEF 3.1EP-MarineEF 3.1EP-TerrestrialEF 3.1POCPEF 3.1ADP-Minerals&MetalsEF 3.1ADP-FossilEF 3.1WDPEF 3.1Production (A1 - A3)Construction (A4 - A5)End of Life (C1 - C4)Additional Environmental InformationNoneFurther InformationTechnical characteristicsNameValueUnitResistance to upward loadNPDNDResistance to downward loadNPDNDReaction to fire, upstand acc.
