title A Comparative Investigation into a Process-Based Approach to Lighting Studies Using Physical and Computer Generated Models in Design Studio
source CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 107-121
summary This pilot research attempts to investigate differences in process between lighting study using physical model and computational simulation. A Physical modelling team, a computational modelling team, and a monitoring and tracking team were formed to process and monitor the research by a defined workflow of the design process. Using a time schedule technique, the procedures of each of the two methods were tracked. The research reveals that the research team favoured physical modelling for its ease of use and computational simulation for its flexibly. And that the users of physical models were more aware of the need for technical knowledge whilst the users of simulation software are more contended with the virtual results without evaluating them critically. In addition, the experiment also shows that the feedback mechanism of the physical modelling process is instant, continues and intuitive, whereas that of the computational process is discrete. Preliminary results not only confirm the long established view that the computational process lacks the tactile quality required for architectural understanding; worst still, it gives inexperienced users an illusion of knowledge and claims of understanding. Due to limitations of time, the research captures only the feasibility stage of the design process, further works involving a more comprehensive design program should be conducted.
