General comment The data selected for LCA analysis originates from ITB-LCI questionnaires completed by DC-System Insulation A/S using the inventory data, ITB database, Ecoinvent database v. 3.10. 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 sufficient for calculations. Data for Danish electricity was supported by Ecoinvent database v. 3.10. Specific EPDs were used for PU/PIR foam and cement-bonded particle boards. Environmental characteristics that were not included in these EPDs sent by the manufacturer were taken from the Ecoinvent.
The allocation rules used for this EPD are based on general ITB PCR A, v. 1.6. Production of the DC-Thermopanel Wall is a line process conducted in the factory of DC-System Insulation A/S, located in Aars (Denmark). Allocation was done on product mass basis. All impacts from raw materials extraction and processing are allocated in module A1 of the LCA. Impacts from the DC-System Insulation A/S production were inventoried on the annual production volume expressed in m2. Water and energy consumption, associated emissions and generated wastes are allocated to module A3. Energy supply was inventoried for whole production process. Packaging materials were taken into consideration.
Minimum 99,0 % input materials and energy consumption (electricity, fuel oil) were inventoried in a processing plant and were included in the calculation. In the assessment, all significant parameters from gathered production data are considered, i.e. all material used per formulation, utilized thermal energy, and electric power consumption, direct production waste and available emission measurements. Tires consumption for transport was not considered. Substances with a percentage share of less than 0.1 % of total mass were excluded from the calculations. The packaging products (wooden pallets) are included. 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.
