【 摘 要 】

The rapid enhancement of computers' power and the boom of open-source software development have offered a broad range of possible applications in architectural design. Grasshopper is a visual programming language developed for the 3D CAD modeling program, Rhinoceros. Utilizing Grasshopper's free software extensions, it is possible, among other things to evaluate the environmental performance of architecture in the early conceptual stage. This paper introduces a novel approach to architectural designing presented in a case study in the extreme environment of Reykjavik's airport. The shape of the airport building formed within this case study can be parametrically changed, and the performance of the various shape modifications in the wind can be tested. Using Ladybug and Swift for Grasshopper, the wind situation at the airport is analyzed, and the aerodynamic shape of the proposed airport building is evaluated in the prevailing easterly winds. The proposed bio-climatic architectural design approach incorporates the surrounding micro-climatic conditions, wind in particular, as a driving factor already in the phase of first design ideas. The parametrically developed airport is formed with regard to the pedestrian wind comfort, as well as airport traffic safety.
