Parametric (Geo)Design for Test Planning

Abstract

The revised Swiss Spatial Planning Act (RPG 2016) pursues the goal of inward settlement development to slow down urban sprawl and better protect arable land. This needs to be addressed in planning processes, as quality-oriented and sustainable internal densification is required. The Geodesign Framework by Steinitz is suitable for supporting such planning processes with public participation, where models and visualizations help to convey the complex systemic interrelationships to stakeholders. This paper presents a process model based on Geodesign that integrates GIS and Parametric Design, so that effects on internal densification caused by changes to building regulations can be quantified and communicated. In addition to an overview of the process model, selected results from its tests and verification are presented. The results suggest that the model approximates real interrelations well and is a suitable basis for further work.
