summary |
With the democratization of information and communication technologies, simulation techniques that used to be computationally expensive and time-consuming are becoming feasible instruments for the analysis of architectural design. Simulation is an indispensable ingredient of the descriptive design approach, which provides the designer with precise and accurate projections of the performance and behavior of a design. The paper describes the application of a particular class of simulation techniques, computational fluid dynamics (CFD), to the analysis and evaluation of indoor climate. Using two different CFD systems as representatives of the class, we describe: relevant computational possibilities and limitations of CFD simulation; the accessibility of CFD simulation for architects, especially concerning the handling of simulation variables; the compatibility of CFD representations of built space with similar representations in standard CAD and modeling systems, including possibilities for feedback; The relations between geometric representation and accuracy / precision in CFD simulation. We propose that CFD simulation can become an operational instrument for the designer, provided that CFD simulation does not become a trial and error game trying to master computational techniques. A promising solution to this problem is the use of case based reasoning. A case base of analyzed, evaluated and verified buildings provides a flexible source of information (guidance and examples) for both the CFD simulation and the designer. |
