Complex design strategies using building information models

Abstract

The choice of a chord and its execution should be regarded as a must and not left to arbitrary wish or superficial speculation. (Johannes Itten, 1961) The paper describes a modular concept for the IT-support of planning practice using BIM (Building Information Modelling) and a parameterized building model. The platform used is the modularized software concept for architectural planning in existing built contexts (prototype software FREAK). The current progress in the development of a reasoned support of planning tasks is described in this paper in more detail. The system consists of a series of software prototypes which are linked to the BIM, utilize the specific data within and demonstrate the value of a consist- ent and extendable CAD-model. The “Colored Architecture” software prototype is one such design-support mod- ule of the software platform and enables the designer to experiment with the pa- rameters colour, light and materials in architectural space. This module supports experimentation, assessment and realization of colours and materials in the archi- tectural design process on a new quality. For instance, the integration of “live ra- diosity” light simulation allows a qualified and interactive assessment and evalu- ation of colours and materials in near-real lighting conditions. The paper further elaborates on software prototypes, modules and concepts in- cluding building surveying and the design of self-supporting domed structures.
