jailcd2020137: Optimizing Site Plan Configuration towards Its Minimum Radiation

Abstract

The impact of global warming results in increased building temperatures caused by solar radiation. High demand for building performance efficiencies requires a platform that can integrate design analysis with building performance. Parametric design can be effectively simulating building performance in complex morphology in the initial phase of architectural design. EnergyPlus Weather (.epw) is possible to compare microclimate radiation with different characteristics from different climates. The analysis links the architectural model with the optimization of solar radiation acquisition. This research aims to simulate parametrically three different cities of Indonesia to investigate the design result towards its minimum radiation. The approach used in this research is Generative Algorithms. The method means to iterate the configuration of a 5-story building in the site plan by using Grasshopper tandem with Rhinoceros as 3D modeling as well as Honeybee and Ladybug as parametric simulations engine. The simulation uses the hottest day for analysis recipes. Optimization takes place along with changes in the orientation of the building and radiation income in the site plan. Parametric analysis-based design can be used by practitioners to streamline the site analysis process in taking and determining the configuration and orientation of buildings in an integrated manner.
