A Generative System to support architectural and urban design

The work presents a system able to generate three-dimensional models of buildings, directly within a 3D geobrowser as Google EarthTM. For this purpose we have developed the prototype of a parametric application that allows the designer to handle the architectural shape by using the main constraints belong to urban regulations. The system integrates two different research topics: modelling in geo-referenced environment and modelling constraints. Compared to the related works (Building Modeling within georeferenced environment), our application is the first Generative Design System based on the urban regulation. It is a Decision Support System (DDS), useful at the early stage of city planning as well as at the stage of architectural design. Some case studies are presented in order to test the Generative Design System: the design of residential buildings in an Italian city.
