The EPD is an average EPD for the products: • AML150 • AML300 • AMP500 H, AMP500V, AML500 H, and AML500 V • AMP800 H, AMP800V, AML800 H, and AML800 V • AMP900 H and AMP900 V • AMP1000 • AMP1200 H and AMP1200 V It has not been possible to group the datasets within +/- 10% of the average. Therefore, the EPD is based on a ‘reference worst case product’ within the aforementioned product range. For the AM150, AM300, and AM1000 the results are based on the versions AML150, AML300, and AMP1000. The DVUs are covered by harmonised technical specification EN 1886:2008 and EN 13141-7:2010. Additionally, the DVUs comply with following EU directives: DIRECTIVE 2006/42/EC, DIRECTIVE 2014/30/EC, DIRECTIVE 2009/125/EC, and DIRECTIVE 2011/65/EU. Further technical information can be obtained by contacting the manufacturer or on the manufacturer’s website: • https://airmaster.dk/produkter/vaeghaengteventilationsanlaeg • https://airmaster.dk/produkter/ventilationsanlaeggulvstaaende For the specific available options and models of the DVUs contact Airmaster A/S. Foreground system: The products are produced without using any GO’s. The energy process is modelled using ‘electricity, medium voltage, residual mix’ for Denmark from EcoInvent. Background system: Most of the upstream processes have electricity included modelled using the grid mix. For some specific processes where it has been possible to define the specific electricity mix, these were modelled using the country-specific residual mix. Downstream processes are modelled using electricity grid mix for RER. The product stage comprises the acquisition of all raw materials, products and energy, transport to the production site, packaging and waste processing up to the ”end-of-waste” state or final disposal. The LCA results are declared in aggregated form for the product stage, which means, that the sub-modules A1, A2 and A3 are declared as one module A1-A3. Steel: The DVUs have a steel cabinet which account for the majority of the weight. The scrap content in the steel varies from 17.4-18.2%. The cabinet sheets are bended, welded, and surface treated at the suppliers before arriving at Airmaster. A process has been included in module A1 to account for these processes. Additionally, small fixing parts is included in the steel. Aluminium: The aluminium is modelled as primary aluminium. Plastic: There are several types of plastic components in the DVUs which are modelled using representative datasets on the plastic types. A process is included to account for the moulding and shaping of the plastic components. Electronic: As the DVUs are an electronic ventilation unit, several electronic components are present in the unit. These are modelled based on information from suppliers. Insulation: The DVUs are insulated using PE foam, PU foam and bonded foam. Bonded foam is a secondary material and thus included without any impacts. However, impacts associated with shredding and adhesive to mould bonded foam is included. Generally, the components of the DVUs are premanufactured and assembled manually at the production sites in Aars (DK). Airmaster has three different production sites in Aars where the DUVs are assembled. Energy from these sites has been allocated based on man-hours for the assembly of the units. Construction process stage (A4-A5) includes: Module A4 includes the impacts associated with the transport of the finished product. The finished product is distributed to different markets in EU. The utilization capacity of the truck (including empty return) is 47.8%. Additionally, transportation with ship is also included. The utilization capacity is 70%. A weighted average distance has been calculated based on the market distribution. The installation of the DVUs is done manually. Therefore, the energy needed for this process is only associated with an electric screwdriver. Additionally, screws are needed for installation. These two processes are excluded due to the negligible impacts. Module A5 includes the end-of-life treatment of the packaging. Here, cardboard, LDPE foil and EPS are assumed recycled. AM150, AM300, and AM 1200 are distributed on EUR wooden pallets. Due to the durability of EUR-wooden pallets it is assumed that the pallets are reused 25 times. Thus, 1/25 of the EUR pallet is attributed to these ventilation units. For AM500, AM800, AM 900, and AM1000 customised pallets are used. These are one time use due to customised dimensions and therefore the whole pallet is modelled. Wooden pallets are assumed incinerated after use. Use stage (B1-B7) includes: B1 + B3-B5 + B7: As this is an electronic component, all the b-modules must be declared. B1: During the use, no emissions to the environment are expected during the reference service life. B3-B5: No repair, replacement, or refurbishment due to damage is expected within the reference service life of 25 years (module B3-B5). B7: There is no operational water use to operate the DUVs, therefore no environmental impacts are included in module B7. B2: To maintain the performance of the DVUs and ensure a continuous supply of fresh, ventilated air continuously throughout their lifetime, it is necessary to replace ventilation filters. Airmaster recommends replacing both the supply and exhaust filters annually to maintain optimal DVU performance. The production of new filters is accounted for in B2 according to EN 15804 + A2. Additionally, the waste treatment of used filters is considered in B2. It is important to note that B2 is modelled for one year to align with the B modules and does not represent the estimated reference service life of 25 years. B6: The Ecodesign Directive (COMMISSION REGULATION (EU) No 1253/2014 of 7 July 2014 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to Ecodesign requirements for ventilation units) is used to determine the reference capacity and thus the energy use of the ventilation units. The Ecodesign requirements determine that the reference flow rate as 70% of the maximum flow rate. The annual operating hours are set to 8760 hours as a conservative approach which is in accordance with the default value that is used in the Ecodesign directive to calculate the SEC (specific energy consumption). For this EPD the reference scenario is based on the use of the filters ePM10 50%/ ePM10 50% with a 30 dB(A). The RER electricity mix has been applied to model the usage of energy for the DVUs, as the geographical scope is European. B6 is modelled for 1 year and does therefore not represent the estimated reference service life of 25 years. According to the Danish Building Regulation, B6 from EPDs is not used in the LCA modelling of buildings. Therefore, one year has been included to indicate an average electricity use for the given scenario. End of Life (C1-C4) includes: No impacts from dismantling have been included in module C1 as this is done manually. Module C2 includes the impacts associated with the transport of the waste from the dismantling to the waste handling. The product is placed on different European markets, average distances to waste handling for countries have been included to account for the different distances. Module C3 contains the impacts of waste handling. The waste scenario is derived from EN 50693:2019 Product Category Rules for the life cycle assessments of electronic and electrical products and systems. Due to uncertainties surrounding the disposal of electronic and electrical equipment (EEE) and variations in waste management practices across different European countries, the waste handling of these units is based on EN 50693:2019. The waste scenario is a default scenario, and the values will vary depending on the specific EEE product. Energy for shredding the DVUs are included. Module C4 covers the impacts of landfilling. Following waste treatment rates (recycling, incineration, and landfilling) are included in the waste treatment. Re-use, recovery and recycling potential (D) include: In module D potential benefits from recovery and recycling of materials in the product are calculated. The materials are either used as secondary materials in a new product system, thus substituting virgin materials, or incinerated with energy recovery. To avoid double counting, the amount of scrap in the steel and bonded foam is not credited in module D.

Decentralised ventilation unit for rooms. The function of the DVUs is to provide fresh air by circulating air through supply and exhaust filters which removes dust and particles and lowers the CO2 levels in the indoor climate. The DVUs allow being installed on the wall and ceiling. The units are applicable for larger rooms with a higher activity of people such as classrooms, offices, and meeting rooms etc. The unit has an automatically adjustable supply that adjusts the diffusion of air in the room.
