General comment The data selected for LCA originate from ITB-LCI questionnaires completed by producer. 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 background data for the processes come from the following resources: database Ecoinvent v.3.11 and KOBIZE (Polish electricity mix and combustion factors for fuels). KOBIZE data is supplemented with Ecoinvent data on the national electricity mix impact where no specific indicator data is provided. 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. Production of the ETICS is a line process (as presented in Figure 2) conducted in the two manufacturing plant located in Kuznica Kiedrzynska or Wanaty near Czestochowa. Input and output data from the production is inventoried and allocated to the production on the mass basis. The declaration covers all ETICS products manufactured in the plant. Their production resources and processing stages are basicly similar, so it is possible to average the production by product weight.
Minimum 99.0% input materials and 100% energy consumption (electricity, gas, LPG, other) were inventoried in a processing plant and were included in the calculation. 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 usage and mass per modules A or D. Machines and facilities required during production are neglected.
