Abstract
Dette speciale tager udgangspunkt i klimakrisen og den centrale rolle, som byggeriet spiller for at reducere drivhusgasudledninger. Renovering er afgørende for at nedbringe driftsrelaterede emissioner, men kan samtidig øge de forudgående materialerelaterede emissioner (indlejret CO2). Specialet undersøger derfor, hvordan en cirkulær renoveringstilgang, som kombinerer energieffektivitet med genbrug og genanvendelse af materialer, kan blive adopteret i den danske byggebranche. Med en litteraturgennemgang af akademiske og grå kilder om cirkulær økonomi og indlejret CO2, et analytisk afsæt i omstillingsteori (lock-in og strategisk nicherstyring), kvalitative interviews med brancheprofessionelle og eksplorative casestudier af to europæiske demonstrationsprojekter (RenovActive i Belgien og Slovakiet) belyser specialet både barrierer og muligheder. Analysen identificerer teknologiske, organisatoriske, industrielle, samfundsmæssige og institutionelle barrierer for cirkulære tilgange og renovering, og peger på, at politisk handling og demonstrationsprojekter har potentiale til at flytte renoveringsdagsordenen i en mere cirkulær retning. Specialet skitserer skridt mod implementering i Danmark og fremhæver læring, netværk og gennemsigtighed om materialer som vigtige drivere; det anerkender samtidig begrænsninger ved case- og interviewudvælgelsen.
This thesis addresses the climate emergency and the critical role of the built environment in reducing greenhouse gas emissions. While renovation is key to cutting operational emissions, it can increase upfront, materials-related emissions (embodied carbon). The study therefore explores how a circular renovation approach—combining energy efficiency with the reuse and recycling of materials—can be adopted in the Danish construction sector. It draws on a review of academic and grey literature on circular economy and embodied carbon, an analytical framework from sustainability transitions (lock-in and Strategic Niche Management), qualitative interviews with industry professionals, and exploratory case studies of two European demonstration projects (RenovActive in Belgium and Slovakia). The analysis identifies technological, organizational, industrial, societal, and institutional barriers to circular approaches and renovation, and finds that governmental action and demonstration projects can steer the renovation agenda toward circularity. The thesis outlines steps toward implementation in Denmark and highlights learning, networks, and material transparency as important enablers, while acknowledging limitations related to case selection and interview sampling.
