Abstract
Dette projekt undersøger, hvordan en arkitektvirksomhed praktisk anvender evidensbaseret design (designbeslutninger baseret på forskning og data). Målet var at udvikle en metode i Rhinoceros 3D med Grasshopper, der både integrerer evidensbaseret viden i de tidlige skitsefaser og hjælper med at vurdere, om designforslag opfylder fastsatte kriterier med fokus på patientsikkerhed. Studiet kombinerede kvalitative og kvantitative tilgange: interviews med arkitekter og sundhedspersonale, scenariemodeller udviklet i samarbejde med arkitekter, samt parametrisk 2D/3D CAD-modellering (modeller styret af justerbare parametre) til at skabe metode- og værktøjsprototyper. Prototyperne blev evalueret gennem kognitiv gennemgang (en struktureret evaluering af, hvordan et værktøj bruges) og spørgeskemaer. Der blev gennemført to undersøgelser med i alt 9 individuelle respondenter; 18 spørgeskemaer blev udsendt, hvoraf 10 besvarelser indgik i analysen. Resultaterne viser, at et softwarebaseret designværktøj har væsentlige potentialer. Arkitekterne vurderede prototyperne som et brugbart og værdifuldt bud på at 1) integrere og anvende evidensbaseret information og 2) optimere designprocesser og sundhedsfaciliteters umiddelbare effekt. Videre udvikling bør fokusere på informationsstrukturering som fundament for parametrisk design samt på at tilpasse prototyperne til implementering i Building Information Modelling (BIM), dvs. digitale bygningsmodeller.
This project examines how an architecture firm puts evidence-based design (design decisions guided by research and data) into practice. The goal was to develop a method in Rhinoceros 3D with the Grasshopper plugin that both brings evidence-based knowledge into the early sketch phases and helps assess whether design proposals meet defined criteria with a focus on patient safety. The study combined qualitative and quantitative approaches: interviews with architects and healthcare staff, scenario models co-created with architects, and parametric 2D/3D CAD modeling (models driven by adjustable parameters) to build method and tool prototypes. The prototypes were evaluated through cognitive walkthroughs (a structured review of how a tool is used) and questionnaires. Two studies were conducted with 9 individual participants; 18 questionnaires were distributed, and 10 completed responses were analyzed. Findings show that a software-based design tool has significant potential. Architects viewed the prototypes as a useful and valuable way to 1) integrate and use evidence-based information and 2) optimize design processes and the immediate effects of healthcare facilities. Further development should focus on information structuring as a foundation for parametric design and on adapting the prototypes for implementation in Building Information Modeling (BIM), i.e., digital building models.
