Abstract
Dette speciale undersøger, hvordan boligkøbere kan motiveres til at energirenovere, set gennem en praksisteoretisk tilgang. Baggrunden er Danmarks mål om at blive uafhængig af fossile brændsler i 2050 og den store energibesparelsesmulighed i den eksisterende boligmasse, især huse opført før 1980. Med udgangspunkt i et litteraturreview, semistrukturerede interviews med centrale aktører og en workshop med to ejendomsmæglere, to energirådgivere og tre husejere kortlægges de praksisser, der præger bolighandel og renoveringsbeslutninger. Analysen identificerer professionelle aktører, der kan fungere som fortalere for energirenovering, samt væsentlige drivkræfter og barrierer for boligkøberes motivation. En hovedkonklusion er, at der ikke findes en generisk løsning: Boligkøberes vilje til at investere afhænger af, at renoveringsudbyttet passer til deres præferencer, og af de konkrete, materielle forhold i den enkelte bolig—begge dele varierer betydeligt. Da eksisterende virkemidler som energimærket ofte opleves som begrænsede i deres effekt, foreslår specialet at digitalisere og individualisere energimærket for at koble anbefalinger og incitamenter tættere til den enkelte køber og bolig.
This thesis examines how to motivate house buyers to undertake energy renovations using a Practice Theory approach. The study is framed by Denmark’s 2050 fossil-fuel independence goal and the large savings potential in the existing housing stock, especially homes built before 1980. Drawing on a literature review, semi-structured interviews with key actors, and a workshop with two realtors, two energy advisors and three homeowners, the authors map the practices that shape home sales and renovation decisions. The analysis identifies professional actors who can act as proponents of energy renovation, as well as key drivers and barriers affecting buyers’ motivation. A central finding is that there is no one-size-fits-all solution: buyers’ willingness to invest depends on outcomes aligning with their preferences and on the material conditions of the specific house—both of which vary widely. As existing instruments such as the Energy Performance Certificate often have limited effect, the thesis recommends digitalizing and personalizing the certificate to better tailor recommendations and incentives to individual buyers and homes.
