General comment BB31 is a wall mounted bench, which is delivered unassembled. Boards are available in clear lacquered birch, beech, oak or pine and with a frame in black powder-coated steel. The benches are available in lengths between 600 mm and 2000 mm, with an increase in steps of 100 mm. The EPD declares an average product of one piece of bench, which is one meter long.

All data that is specific to the product and process was provided by the manufacturer for the operating year 2024 and is therefore up-to-date. The manufacturer and their production are located in Karlstad, Sweden.
Background data was taken from the Ecoinvent 3.9.1 database. The database is regularly checked and thus complies with the requirements of ISO 14040/44 (background data not older than 10 years). The background data meets the requirements of EN 15804.
The general rule was followed that specific data from specific production processes or average data derived from specific processes must be given priority when calculating an EPD or Life Cycle Assessment. Data for processes that the manufacturer cannot influence or choose, were backed up with generic data.
The scenarios included are currently in use and are representative for one of the most likely scenario alternatives. According to the criteria of the "UN Environmental Global Guidance on LCA database development" mentioned in EN 15804+A2, the data quality for all three representativeness categories (geographical, technical and time) can be described as good.
The calculations have been performed in accordance with the “polluter pays” and “modularity” principles, as defined in EN 15804+A2.
The following estimates and assumptions have been made for this EPD:
The racks are available in lengths between 600 mm and 2000 mm, with an increase in steps of 100 mm. The mass of materials was calculated by dividing all used materials by all sold bench lengths in 2024.
The energy per declared unit refers to the average amount of energy used for their total production in 2024. Energy use due to cutting and phasing is minimal during the production of the bench BB31. The customer assembles the wooden boards on the metal consoles by themself.
