General comment
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.

Technical purpose
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.
