- Abstract (Swedish)
- Klimatförändringarna är en av de största samhällsutmaningarna i vår tid och det ställs därför högre av på dagens byggande och materialval. Cirka en femtedel av Sveriges utsläpp kommer från byggbranschen där materialtillverkning och produktionsutsläpp inkluderas. För att minska klimatpåverkan kan strategiska materialval göras för att sänka koldioxidutsläppen. Många gånger görs detta genom att titta på stommaterial och utbytbarheten av dessa, men det finns även andra materialval som är minst lika viktiga; värmeisolering. I driftskedet av en byggnad är värmeisolering en avgörande faktor om en byggnads energiprestanda.

Cirka en femtedel av Sveriges utsläpp kommer från byggbranschen där materialtillverkning och produktionsutsläpp inkluderas. För att minska klimatpåverkan kan strategiska materialval göras för att sänka koldioxidutsläppen. Många gånger görs detta genom att titta på stommaterial och utbytbarheten av dessa, men det finns även andra materialval som är minst lika viktiga; värmeisolering. I driftskedet av en byggnad är värmeisolering en avgörande faktor om en byggnads energiprestanda.
Idag finns det olika typer av värmeisoleringsmaterial, biobaserade och konventionella alternativ. Forskning visar att biobaserade isoleringsmaterial har en lägre klimatpåverkan än konventionella, men ändå väljs de konventionella materialen i högre utsträckning vid nyproduktion.
Det sker en avvägning mellan materialegenskaper hos biobaserade respektive konventionella isoleringsmaterial, skapar ett behov av att identifiera de barriärer och drivkrafter som styr materialvalet i praktiken. Det saknas en samlad förståelse för hur dessa avvägningar görs och vilka faktorer som är avgörande, vilket är vad denna studie syftar till att undersöka.
För att kunna kartlägga dessa drivkrafter och barriärer används fem olika metoder: litteraturstudie, intervjustudie, fallstudie, dokumentgranskning och tematisk analys. Dessa är till för att identifiera de olika isoleringsmaterialens egenskaper, förstå hur de används och upplevs praktiskt och hur projekt har påverkats av dessa materialval.
Det finns en vilja och teknik till att börja implementera dessa i en bredare utsträckning men att det finns faktorer som skapar barriäreffekter. Dessa faktorer handlar om ekonomi, kunskapsbrister, tekniska osäkerheter och regulatoriska krav. Samtidigt visade resultatet att det finns drivande faktorer till implementering vilket är minskad miljöpåverkan, hållbarhetsmål och förekomst av referensobjekt där dessa biobaserade material har använts.
Sammanfattningsvis fattas beslutet om värmeisolering på ekonomiska och organisatoriska grunder, snarare än tekniska. Implementeringen kan öka av dessa biobaserade material om det finns tydliga hållbarhetsmål, engagerade aktörer, referensobjekt, tydliga standarder samt fortsatt forskning kring långtidsprestanda och att klimatnyttan värderas högre i byggprojekt.

- Climate change is one of the biggest societal challenges of our times, which is why high standards are set on today’s building construction and material choices. Around one fifth of the total carbon emissions from Sweden comes from the construction industry where material manufacturing and production are included. Through strategic material choices, could the carbon emissions be reduced. This is often made with body material in buildings where they look at the interchangeability of them but there are other materials that could recuse carbon emissions as well; heat insulation. In the operational phase of a building is heat insulation, one of the most important factors for the building´s energy performance.

Today there are different kinds of heat insulation, biobased insulation and conventional insulation.

The tradeoff between the material properties of biobased and conventional insulation, which creates a need to map the barriers and drivers what’s the reason is to choose one of the materials. There is missing a collected understanding of how these materials are balanced to make a choice, which is what this study intends to do.
To map these drivers and barriers are five methods used: an literature study, an interview study, a case study, document scanning and a thematic analysis. These methods are used to identify material properties of the insulation materials, understand how they are used and are experienced and examine how projects are affected by them.
The result shows that there are both will and technical possibilities to implant these biobased insulation materials but there are factors that make these barriers. These factors are mainly economics, lack of knowledge, technical uncertainties and regulatory requirements. But the result also showed that there are also factors that are driving these implementations, which are reduced environmental impact, sustainability goals and that there are reference objects with these biobased materials.
To sum up, decision about heat insulation is grounded more on economical and organizational rather than technical. The implementation of biobased insulation could increase if there are clear sustainability goals committed by actors, reference objects, clear standards and continued research of long term performance and thar climate benefits are valued more highly in construction objects.
