Mitt examensarbete, Regelverk, Konstfack 2024, kandidatprogrammet Inredningsarkitektur och möbeldesign, syftar till att utveckla och formge möbler av använda träreglar från byggindustrin. Idag görs återbruksdesign ofta i begränsat antal och som unika objekt på grund av den begränsade tillgången på material. Dessa möbler har ofta en experimentell och “skräpig” estetik som inte tilltalar en bred konsumentgrupp. Samtidigt står byggbranschen för en stor del av samhällets avfall, och mängder träreglar demonteras vid rivningsarbeten och bränns upp för energiutvinning, vilket strider mot EUs direktiv. Jag såg en möjlighet att ta tillvara på träregeln och presentera en ny typ av återbruksdesign som inte kompromissar med form, samtidigt som inte ett enda träd behöver fällas.  I mitt arbete har jag utvecklat befintliga metoder för hur det billiga materialet kan förädlas. Jag har undersökt hur regeln kan bearbetas för att få fram olika estetiska kvaliteter och hur dessa kan presenteras i möbler. Många av mina resultat har framkommit efter upprepade tester i skala 1:1, och mycket av arbetet har tagit plats i Konstfacks träverkstad.  Designförslagen jag presenterar är en serie möbler där jag visar olika metoder för hur jag bearbetat träregeln. Jag har producerat fyra olika typer av matstolar, ett matbord, en fåtölj och en soffa. I projektet Regelverk vill jag visa att det går att förena estetiska och funktionella krav med återbrukade material.

This study compares two wood materials, cross-laminated timber (CLT) and traditional wood studs, for small house construction. The aim of this degree project is to assess their specific properties and differences in terms of sustainability and safety. The method for the study employs semi-structured interviews, development of wall elements using Revit and an extensive literature review to arrive at conclusions. CLT is examined as an innovative construction material known for its high strength and stability, while wood studs are analyzed for their energy efficiency and compliance with modern building standards. The findings are supported by previous research comparing different wood construction methods. Through a comprehensive analysis, this study provides valuable insights into the advantages and disadvantages of CLT and traditional wood studs for small house construction. The results from this work were that CLT used more material and had more waste than traditional wood. The interviews indicated differences and challenges related to fire risks associated with adhesive use in cross-laminated timber. Both PUR adhesive and MUF adhesive have their advantages and disadvantages, so it is important to follow the safety protocols and increase industry knowledge for improving fire safety in cross-laminated timber. The conclusion of the study was that cross-laminated timber is affected by the adhesive when considering the reuse of wall elements and fire challenges. It also requires more material, making traditional timber studs a better choice.

To save energy it’s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more moisture to dry. More moisture in combination with higher relative humidity may pose a higher risk of microbial growth. The purpose of this study was to investigate what is a reasonable moisture content in wood studs in four different well-insulated exterior walls. It has also been investigated how moisture rearrangements effect the exterior walls. The software Wufi2D, which does moisture-simulations, was used to collect data. The results have been analyzed in Wufi Bio which showed that the moisture content should be somewhere between 12.5 to 18.5%, depending on how the wall is built. The conclusions are that windbreaks vapor resistivity is essential for what is a reasonable built in moisture content in the wood studs. Depending on the materials that are used, it´s important to consider how much moisture the wall construction contains.
