- Abstract (Swedish)
- Byggindustrin är idag en stor källa till CO2-utsläpp. För att minska bygg- och anläggningssektorns klimatpåverkan, som idag genererar 21 procent av Sveriges utsläpp av växthusgaser, krävs en omställning mot en mer cirkulär ekonomi. Innerväggar utgör en betydande del av den färdiga byggnadens klimatavtryck. Materialval och typ av innerväggssystem kan påverka och reducera detta. Kontorsbyggnader är storskaliga byggnader med stor andel lätta icke bärande innerväggar. Att byta ut dessa innerväggar mot mer cirkulära alternativ hade gett en påtaglig minskning av branschens utsläpp.
Det var därför relevant att undersöka hur innerväggarna i en kontorsbyggnad kunde förbättras genom att använda mer hållbara och klimatsmarta material och lösningar....

Innerväggar utgör en betydande del av den färdiga byggnadens klimatavtryck. Materialval och typ av innerväggssystem kan påverka och reducera detta. Kontorsbyggnader är storskaliga byggnader med stor andel lätta icke bärande innerväggar. Att byta ut dessa innerväggar mot mer cirkulära alternativ hade gett en påtaglig minskning av branschens utsläpp.
Det var därför relevant att undersöka hur innerväggarna i en kontorsbyggnad kunde förbättras genom att använda mer hållbara och klimatsmarta material och lösningar. Exempel på sådana kan vara lågvärdigt biobaserade material eller material som ingår i ett biobaserat cirkulärt kretslopp. Detta examensarbete utgjorde det första steget i Vinnovaprojektet ”Utvärdering och förkvalificering av innerväggssystem baserat på lågvärdiga biobaserade material” i samarbete med NCC.
Arbetet utfördes som en litteraturstudie och inleddes med en definition av begreppet cirkulär ekonomi och en kartläggning av relevanta funktionskrav för en kontorsinnervägg. Utifrån kraven sammanställdes ett kontrollprogram. Kontrollprogrammet bestod av en tabell med gradering av hur väl de enskilda materialen uppfyllde kraven. Detta åskådliggjordes med hjälp av färger. En inventering av dagens innerväggssystem redovisades vidare och nya alternativa material undersöktes. Detta ledde fram till att en hållbar och klimatsmart kontorsinnervägg togs fram bestående av cirkulära material.
Resultatet gav tre förslag på hållbara innerväggssystem anpassade för kontorsbyggnader. Förslagen utvärderades med hjälp av kontrollprogrammet och diskussion fördes kring för- och nackdelar med de olika alternativen. Valen gjordes med hänsyn till hur väl de enskilda materialen samt materialen i samverkan uppfyllde, eller har potential att uppfylla, funktionskraven.
Slutsatsen som kunde dras var att de tre varianterna av innerväggar som togs fram kunde bidra till och ingå i den cirkulära ekonomin eftersom de tillverkades av hållbart material. Det fanns goda möjligheter att redan idag implementera väggarna som togs fram i detta arbete, Typvägg 1 och 2, som bestod av material med låg klimatpåverkan. Detta såg inte heller ut att påverka väggens förmåga att uppfylla funktionskraven. Många av materialen som användes i de tre typinnerväggarna förbättrade även komforten inne i kontoren då de är värmetröga, har goda fuktegenskaper och är lågemitterande. (Less) - Abstract
- The construction industry today is a major source of CO2-emissions. In order to reduce the climate emissions of the building and construction sector, which today is 21 percent of Sweden's climate emissions, a transition towards a more circular economy is required. Interior walls make up a significant part of the finished building's climate impact. Material selection and type of interior wall system can affect and reduce this climate footprint. Office buildings are large- scale buildings with a large proportion of light, non-load-bearing interior walls. Replacing these inner walls with more circular alternatives would have resulted in a significant reduction in the industry's climate emissions.

Office buildings are large- scale buildings with a large proportion of light, non-load-bearing interior walls. Replacing these inner walls with more circular alternatives would have resulted in a significant reduction in the industry's climate emissions.
It was therefore relevant to investigate how the interior walls of an office building could be improved by using more sustainable materials and solutions. Examples of such can be low-value bio-based materials or materials that are part of a bio-based circular cycle. This thesis was the first step in the Vinnova project “Utvärdering och förkvalificering av innerväggssystem baserat på lågvärdiga biobaserade material” (translation: evaluation and pre-qualification of interior wall systems based on low-value bio-based materials) in collaboration with NCC.
This report was carried out as a literature study and began with a definition of the concept of circular economy and a mapping of relevant functional requirements for an office interior wall. Based on the requirements, a control- program was compiled. The control-program consisted of a table, grading how well the individual materials met the requirements. This was illustrated using colors. An inventory of today's interior wall systems was further presented and new alternative materials were investigated. This led to the stage of composing a sustainable office interior wall consisting of circular materials.
The result gave three proposals for sustainable interior wall systems adapted for office buildings. The proposals were evaluated with the help of the control- program and a discussion was held about the pros and cons of the various alternatives. The choices were made regarding to how well the individual materials and the materials in combination met, or have the potential to meet, the functional requirements.
The conclusion that could be drawn was that the three variants of interior walls that were developed could contribute to and be part of the circular economy because they were made from sustainable materials. There were good opportunities to already implement the walls, Typvägg 1 and 2, which consisted of materials with a low climate impact. This also did not appear to affect the wall's ability to meet the functional requirements. Many of the materials used in the three types interior walls also improved the comfort inside the offices as they are heat resistant, have good moisture properties and are low-emitting. (Less)
