The studies investigate the field of evidence-based design used in architectural design practice and propose a method using 2D/3D CAD applications to: 1) enhance integration of evidence-based design knowledge in architectural design phases with a focus on lighting and interior design and 2) assess fulfilment of evidence-based design criterion regarding light distribution and location in relation to patient safety in architectural health care design proposals. The study uses 2D/3D CAD modelling software Rhinoceros 3D with plug-in Grasshopper to create parametric tool prototypes to exemplify the operations and functions of the design method. To evaluate the prototype potentials, surveys with architectural and healthcare design companies are conducted. Evaluation is done by the administration of questionnaires being part of the development of the tools. The results show that architects, designers and healthcare design advisors recon the tool prototypes as a meaningful and valuable approach for 1) integrating and using evidence-based information; and 2) optimizing design processes and health care facility performances. Further study focuses on parametric information relations in Building Information Modelling projects. Keywords: hospital lighting design, evidence-based design, patient safety, architectural design, building information modelling, parametric design, observation and questionnaires, prototypes.
