ALUR KERJA BARU SIMULASI PERFORMA BANGUNAN DALAM PROSES DESAIN PARAMETRIK

This paper describes the new workflow relationship between the 3D CAD Modeler (Rhino/Grasshopper) and lighting simulation (Radiance/Daysim). A very effective design workflow in Rhino presented directly by exporting geometry, material properties, and sensor grids into Radiance/Daysim format to calculate a set of performance indicators including solar radiation maps and daylight distribution factors in a year. The simulation results are automatically sent back to the Rhino using color mapping. By using Grasshopper, the main design parameters such as window size and description of materials can be changed gradually and the simulation results can be combined into a building performance simulation in the form of parametric transformation animation. The Workflow has been specifically developed for the architectural design process by providing all the interactive feedback that is very useful for a designer from the schematic design phase until the design development stage.
