The research questions reads: “How to increase the adoption of sustainable renovations in listed cultural heritage buildings by providing insight into the decision-making process of owner-occupiers?” The research method first includes a theoretical study about the factors that influence the rate of adoption. Second, semi-structured interviews were held chronologically with 7 professionals, 9 LCHB owners and 7 professionals. And lastly, a workshop about the barriers of sustainable renovation in LCHBs attended by 25 Dutch professionals. The first round of interviews with 7 professionals and the interviews with 9 LCHB owners led to the creation of a sustainable renovation decision-making process for owners. And the interviews with 9 LCHB owners, the second round of interviews with 6 professionals and the workshop results led to the drivers, barriers, opportunities and recommendations
Furthermore, LCHB owners were asked questions about their sustainable renovation personality, the answers hereof resulted into two very different persona types. These persona types are also based on the characteristics of owners and the barriers they encountered. A recommendation is to take these personas into account when forming a strategies to increase sustainable renovations.
The other recommendations are to: add a building technology professional to the cultural heritage committee, make municipalities communicate more with LCHB owners, make municipalities use infra-red cameras to take some thermal images of before and after a sustainable renovation as inspiration for other LCHB owners, make LCHB owners use infra-red cameras to check if everything is installed properly, subsidize local community-organized information gatherings for LCHB owners, subsidize owners that can realize the sustainable renovation themselves (DIY) but face a lack of money as their main barrier and, lastly, emphasize making LCHBs beautiful and future proof.
