Use advice for data set | This EPD is based on a cradle-to-grave LCA and covers all the life cycle modules A1-A3, A4-A5, B1-B7, C1-C4, and D, in which 100 weight-% of the product has been accounted in accordance with EN 15804+A2 and ITB PCR A (cradle to grave). Energy and water consumption, emissions as well as information on generated wastes were inventoried and were included in the calculation. 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. The boundaries of the system are shown in Figure 2. |
Technical purpose of product or process | The concept behind building integrated photovoltaics is to adapt PV modules to various building applications, primarily as alternatives to traditional construction materials used for building roofs, facades , fronts, curtain wall louvres, skylights, balustrades and specific window joinery panes. The essential component of product is the system of glass-to-glass modules. Bonding two glass panes with plastic films produces safety glass, a product that is popular in civil engineering and architecture, where its applications span partitions, balustrades, canopies, etc. All module types are available in various forms, depending on the vision of the architects (to adapt to the installation method and building form).

General comment on data set | The data selected for LCA originate from ITB-LCI questionnaires completed by ML System. No specific data collected is older than five years and no generic datasets used are older than ten years. The representativeness, completeness, reliability, and consistency are judged as good. The database, ecoinvent 3.9 is utilized for the background system. As a result, both upstream- and downstream activities are based on average supply mixes for the specific country or region depending on the given dataset and KOBiZE data is used (Polish electricity mix and combustion factors for fuels). Specific (LCI) data quality analysis was a part of the input data verification. The time related quality of the data used is valid (5 years). The allocation rules used for this EPD are based on general ITB’s document PCR A. In the modules A1-A3, material losses in the assembly of the products in the factory are defined on the averaged specific values for the site. Input and output data from the production is inventoried and allocated to the products on the mass basis. The declaration covers a wide range of products (averaged). Their production resources and processing stages are basically similar, so it is possible to average the production by product volume. All data obtained from the survey at the solar glass supplier and module manufacturer were taken into consideration, all available data from production have been considered, i.e. all raw materials/elements used as per assembly process, utilized thermal energy, 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 5 % of energy usage and mass per module A, B, C or D. Machines and facilities required during production are neglected. The production of etiquettes, tape and glue was also not considered. |
