30ee9dbd-89ab-4859-b4c1-4d952aba0be3 DWD Sky Light and DWD Sky Vent products The data selected for LCA originate from ITB-LCI questionnaires (1 manufacturing plants) completed by producer and verified via data audit. No data collected is older than five years and no generic datasets used are older than ten years. The representativeness, completeness, reliability, and consistency is judged as good. The background data for the processes come from the following resources database Ecoinvent v.3.9 (energy carriers, polycarbonate, plastics, steels, waste treatment, incineration, and packaging) and specific EPDs (aluminium). The background data for energy is national based on KOBiZE/GUS reports (Polish electricity mix and combustion factors for fuels). Specific (LCI) data quality analysis was a part of the input data verification. Where no background data was available, data gaps were complemented by literature research. The allocation rules used for this EPD are based on general ITB’s document PCR A (EN 15804+A2). The total average product mass recipe per unit was used for the calculations based on input materials mass divided by the number of specific DWD products. The input substances ranges are average values and the composition of specific products complying with the EPD can deviate from these concentration levels in individual cases. 99.8% materials submitted for the formulations and production data were taken into consideration. In the assessment, all available data from production have been considered, i.e. all raw materials/elements used as per formulation process, utilized thermal energy for heating, and electric power consumption. Thus, material and energy flows contributing less than 1 % of mass or energy have been considered. It can be assumed that the total sum of neglected processes does not exceed 1 % of energy use and mass per modules. Machines and facilities required during production are neglected. The production of etiquettes was not considered. Electromechanical elements such as levellers were not taken into account in the calculations. 1 2023 2028 2023-05-26 The main purpose of Sky Light product (EN 14963) is to illuminate large areas with natural light, most often used for halls of various purposes (warehouses, industrial, fair), sports and entertainment buildings, shopping malls. In buildings with a smaller cubic capacity, such as outbuildings, workshops, car washes, public utility buildings, roof skylights also properly fulfill their lighting function. The supporting structure of the roof skylights is made of system profiles made of natural aluminum with a shape that ensures drainage of water. At the customer's request, aluminum profiles can be painted in any color according to the RAL palette. Rooflights are filled with multi-chamber polycarbonate panels available in various colors and thicknesses 10 - 25 mm), with specific heat transfer coefficients (starting from 1.3 W/(m2K). In the standard offer, the supporting structure of the skylight is a base made of galvanized steel sheet with a thickness of 1.5 - 3.0 mm, which should be raised above the roof slope to a height of approx. 15 ÷ 20 cm. DWD offers light strips up to 6 m wide, the length is unlimited due to the panel construction. The task of the Sky Vent products (EN 12101-2) is to remove smoke, heat and fire gases in the event of a fire. Sky Vent smoke vents help to protect human life and property by: removing smoke from escape routes, which will make it easier to leave the building in the event of a fire protection of structural elements and equipment, as well as minimization of damage caused by smoke and hot fire gases facilitating firefighting operations In addition to the smoke exhaust function, during normal use, smoke vents can be used as roof skylights, ventilation hatches or roof hatches. Sky Vent products are also made of steel, aluminum and polycarbonate (with a thickness of 10 to 25mm). Technical data of the products can be found in the manufacturer's catalog from the website. EPD NPCR Part A: Construction products and services. Ver. 1.0. March 2021 average dataset ecoinvent database (all versions) Type of the EPD is: cradle to gate - with options. The following life cycle stages were considered. Production stage including: A1 – Raw material extraction and processing, A2 – Transport to the manufacturer and A3 – Manufacturing, A4- Transport to Site, A5- Installation, End-of-life stage: C1- Deconstruction, C2 – Transport to waste processing, C3 – Waste processing, C4 – Disposal (landfill). This includes provision of all materials, products and energy, packaging processing and its transport, as well as waste processing up to the end-of waste state or disposal of final residues. EPD includes D module- declaration of all benefits and loads beyond product system. Energy and water consumption, emissions as well as information on generated wastes were inventoried and were included. It can be assumed that the total sum of omitted processes does not exceed 5% of all impact categories. In accordance with EN 15804+A2, machines and facilities (capital goods) required for the production as well as transportation of employees were not included in LCA. 456/2023 Ph.D. Eng.
