Dette projekt undersøger, hvordan eksisterende bygninger i Lemvig kan gøres mere robuste, så de kan modstå og leve med vand. Udgangspunktet er en casebaseret problemformulering om, hvilke klimatilpasningstiltag på bygningsniveau der kan reducere effekterne af fremtidige oversvømmelser. Metodisk kombineres litteraturstudie med en vurdering af fare, eksponering og sårbarhed, herunder kortlægning af oversvømmelsestyper og -dybder via historiske hændelser og fremskrivninger (bl.a. stormflodsscenarier, intens nedbør og grundvand). Et teoretisk rammeværk for bygningsmæssig klimatilpasning anvendes til at operationalisere designkriterier og vurdere tiltagenes transformabilitet og adaptivitet. På den baggrund foreslås en portefølje af praktiske løsninger på ejendomsniveau: højdeforøgelse af gulvniveau, tør- og vådforsikring (flood proofing), samt reduktion af regnafstrømning gennem regnbede, grønne tage og permeable belægninger. Projektet munder ud i et forslag til, hvordan kombinationer af disse tiltag kan styrke robustheden af eksisterende bygninger i Lemvig og understøtte en strategi for at leve med vand, samtidig med at mulige samfundsmæssige merværdier (co-benefits) fremhæves. Konklusionen suppleres af en drøftelse af begrænsninger og anbefalinger for næste skridt.

This project examines how existing buildings in Lemvig can be made more resilient to withstand and live with water. It starts from a case-based research question about which building-scale climate adaptation measures can reduce the impacts of future flooding. The methodology combines a literature review with a hazard, exposure, and vulnerability assessment, including mapping flood types and depths using historical events and projections (e.g., storm surge scenarios, intense precipitation, and groundwater). A theoretical framework for building-scale climate resilience is used to operationalize design criteria and assess the transformability and adaptability of proposed measures. Based on this, the study proposes a portfolio of practical property-level solutions: elevating floor levels, dry- and wet-floodproofing, and reducing runoff through rain gardens, green roofs, and permeable pavements. The project outlines how combinations of these measures can strengthen the robustness of existing buildings in Lemvig and support a strategy for living with water, while highlighting potential co-benefits. The conclusion is accompanied by a discussion of limitations and recommendations for next steps.
