Optimization of Heat Gain in Vertical Housing Design for Middle Low Economy, Cengkareng-Jakarta Barat

Abstract

This paper discusses the optimization of heat gain in vertical housing design for the middle-low economy, using rhino, grasshopper, and ladybug simulation. This study aims to explore a vertical housing design that minimizes heat gain, optimizes view, and increases wind speed. The methodology of this research is quantitative, through an experimental method, namely by making a geometry model according to field conditions in the math model (rhinoceros simulation), then simulating solar radiation gain (heat gain) through grasshopper & ladybug simulation. The research step: (1) to analyze microclimate and site context, (2) to make model design simulation-based on Kampong structure (horizontal housing), ( 3) to analyze the radiation gain in the simulation model. (4) to recommend geometric shapes for the most optimal vertical housing gain of solar radiation (heat gain). The results show that from the simulation of 3 models based on the kampong structure's geometry, the most optimal form is the shape that minimizes the orientation of East and West. Modular geometry is the L-shaped shape of the kampong structure module and each floor is laid out on each floor in the opposite direction, thus casting a shadow on each floor. The final form result also provides optimal views and increased wind speed that can dissipate heat.
