Laminated log wall structure
Use advice for data set This EPD covers the following modules: A1 (raw material supply), A2 (transport) A3 (manufacture), A4 (transport to the site) and A5 (construction process), as well as a scenario for End-of-Life and supplementary information beyond life cycle module D).
Technical purpose of product or process This EPD represents the production and assembly of the laminated log wall structures produced by members of Finnish Log House Industry Association. The structure contains laminated (glued) logs, connected with wooden dowels and metal fitting parts, sealing strips and insulation between the logs. Transportation and machine usage needed for assembly at the construction site are included. A laminated log is made of kiln dried dimensioned lumber of pine (Pinus sylvestris L.) or spruce (Picea abies L.) and glued together from two or more pieces, with either a vertical, horizontal or cross seams.
General comment on data set Modules A1 is based on inventory of RTS EPD 124_21 over its modules A1 to A3. All the raw material transportation in A2 is inventoried. In module A3, all used materials, energy, packages and transportation until the end-of-waste state have been included. In module A4, transportation distance to the customer is with partially empty return. All inventories are based on ERP data from the mills. Possible unit processes of direct flows do not exceed 1% cut-off in amount or expected impacts. In module A5, only machine work needed for assembly of the wall structure is inventoried, no other construction resources are included. Necessary fitting materials and sealings included in A5. A scenario for the module B is not presented in this EPD. In a scenario for the module C it is assumed that the de-constructed structure will be directed partly for reuse in module D, incinerated for energy and treated as waste. Metal parts are transported to recycling but considered recycled without burden. Module D considers the net benefits of using laminated logs in energy recovery and reusing material in a new building.

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.
