BOS – Supply air valve
Use advice for data set The studied system boundary was cradle-to-gate with options, modules C1-C4, module D and A4- A5. Studied system covers the following steps of life cycle according to EN 15804:
Technical purpose of product or process The Halton BOS supply air valve is ideal for residential usage. Beautiful in design and best functionality also with low airflow rates. BOS is made of cold rolled and stainless steel, polymers and paint. This EPD represents two BOS product variations: BOS-100 and BOS-125. The mass of 1 unit of BOS-100 product is 0,95 kg, and BOS-125 is 0,93 kg. The GWP-total A1-A3 results between the two product variations differ by less than 2 %, with BOS-100 exhibiting higher GWP-total A1-A3 results. Therefore, BOS-100 is selected based on a conservative approach
General comment on data set Allocation rules used are made according to the ISO14044:2006. Allocation is avoided when possible and when necessary, allocation is made based on physical shares and also avoiding double calculations. Allocation is required if the production process produces more than one product and the flows of materials, energy and waste cannot be separately measured for the studied product. Allocation used in generic data sources follow the requirements of the EN 15804 -standard. It should be noticed that the allocation method ‘allocation, cut-off by classification’ has been used for Ecoinvent 3.10.1 data, which complies with EN 15804. Avoiding allocation could not be avoided for following inputs as the information was only measured on factory process level. • Electricity: only measured on factory level. • Packaging materials: only measured on factory level. The inputs were allocated to studied product based on production volume (mass in kilograms). According to EN 15804, flows leaving the system at the end-of-waste boundary of the product stage (A1-A3) are allocated as co-products. According to EN 15804, process that has a very low contribution to the overall revenue may be neglected in co-product allocation. Steel and aluminium scrap collected from the cutting process is sent for recycling. This process has a low contribution to the overall revenue and may be neglected in co-product allocation. Contributions to the overall revenue of the order of 1 % are considered very low, therefore the co-product allocation is not required and not carried out. Other materials did not carry any benefits towards Halton’s production. Hence, no other co-product allocations were made. This study follows the cut-off criteria stated in RTS PCR and EN 15804 -standard. This study does not exclude any modules or processes which represent more than 1 % of the emissions of studied life cycle stage. The study does not exclude any hazardous materials or substances. Excluded processes and the criteria for exclusion are given in the following table. Machines and facilities (capital goods) required for and during production are excluded, as is transportation of employees.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
