| Use advice for data set | Scope: In this association EPD, a specific product configuration of external Venetian blinds is declared. This external Venetian blinds system is produced by manufacturers that are members of IVRSA. Data are based on production during 2020 – 2022 in Central Europe. Data have been provided by 5 companies that produce ready-to-install sun protection systems (Alulux GmbH, Beck+Heun GmbH, REFLEXA-WERKE Albrecht GmbH, HELLA Sonnenschutztechnik GmbH and WAREMA Renkhoff SE). Additional data have been provided by companies producing specific parts and pre-fabricated products (Somfy GmbH and VEKA AG). The configuration of the external Venetian blinds components is based on the overall bestselling/ most relevant product. System boundary: Declaration type with respect to life cycle stages covered according to clause 5.2 of EN 15804+A2: cradle to gate (A1-A3) with options A4, A5, module B6, modules C1–C4, and module D. Modules A1 to A3: These modules consider the manufacturing of all system components including the provision of all raw materials, semi-finished products and energy, as well as waste processing up to the end-of-waste state or disposal of production waste that occur during manufacturing. The impact of packaging materials is included. Module A4: This module considers 100 km transport to the construction site (Truck transport, diesel, EURO 6) The transport distance can be modified project specific if required by linear scaling of the LCA results of module A4. Module A5: This module considers treatment of packaging material in the installation phase by energy recovery. Thermal treatment in municipal waste incineration (MWI) plants, assuming an R1 value of >0,6. Installation efforts are not declared as installation is assumed to be done manually. Module B6: Calculation of the scenarios according to the PCR Part B: 20,000 cycles for Venetian blinds, whereby a cycle comprises one-time tilting and turning. Module C1: It is assumed, that the deinstallation of the product is done manually. No environmental impacts are therefore assigned to module C1. Module C2: This module considers 50 km transport to the site of waste treatment/ disposal (Truck transport, diesel, EURO 6). Module C3: The end-of-life scenario considers the recycling of metals, which reach the end-of-waste status after de-installation. It is assumed that materials with a calorific value do not reach the end-of-waste status before an incineration process. Thermal treatment of materials in MWI plants, assuming an R1 value of >0,6. Collection rate is set to 100%. Module C4: Regarding disposal an European scenario for average landfill emissions is declared in module C4 for inert materials without a calorific value (e.g. glass fibre). Module D: Module D includes benefits from recycling and incineration of occurring production waste in module A3 and the incineration of packaging materials in module A5 along with benefits from recyclable materials that occur at the end-of-life and benefits related to the incineration processes in module C3. For the thermal and electrical energy generated in modules A3, A5 and C3 due to the thermal treatment of production, packaging and product waste, avoided burdens have been calculated by the inversion of electricity grid mix and thermal energy from natural gas, using European datasets. Period under review The period under review for the collection of production data and resulting averages refers to 2020-2022. | ||

| General comment on data set | External Venetian blinds are external sunblind products. The blind consists of horizontal slats. The slats are mounted laterally in guide rails or guided by ropes and can be aligned by the user, depending on the position of the sun. The external Venetian blind is stowed in a box system when folded. The product can be operated manually or by power. Thermal protection can be achieved in summer by using external Venetian blinds. With this system, the absorption heat resulting from the solar radiation is already dissipated externally in front of the window components to be shaded. The ingress of undesired solar heat in the building interior can be minimised. The respective blinds can achieve almost complete darkening depending on the slat shape. The setting options allow a balance to be established between transparency, daylight utilisation and shading, depending on the position of the sun. This reduces the overheating of buildings and minimises the cooling energy required and the energy used for artificial lighting. | ||

| Technology description including background system | Sun protection systems are an assembly of several components. Process steps can include cutting, bending, stamping, drilling, foaming, coating, plastic injection moulding, plastic extrusion, assembling. 1 m² of the declared external venetian blind consists of the following materials in terms of percentage: Aluminium: 72% Steel: 16% PVC: 3% Metals (Others): 2% PA: 2% Others: 5% Technical data: The applicable data are based on the declaration of performance in accordance with the CPR and the harmonised standards based on the machinery directive. Performance values of the product according to the declaration of performance (CPR) with regard to its essential features in accordance with EN 13659:2004+A1:2008. Declared unit: The declared unit is 1 m of sun protection system according to the PCR. The representative size of the sun protection system refers to a standard window size according to EN 14351-1 with a surface of 1.82 m and a width-height ratio of 1.23 m by 1.48 m. For the calculation of the LCA, processes and masses were scaled accordingly from the representative size to the declared unit. | ||
