As urbanization is speeding all over the world, buildings have responsible for 20% to 40% of global energy consumption and more than 30% of global greenhouse gas emission. With energy efficient designs, buildings can potentially reduce their energy consumption up to 50%, thus climate change improvement can be realized. Recently, several green building rating systems developed as assessment tools to assess the sustainable level of buildings. In many green building rating systems, energy and indoor environmental quality are the top two categories that contributed into the credit points. Those green building rating tools encourages energy efficient designs through optimized thermal performance, incorporating natural ventilation and energy efficient technologies. Natural ventilation is crucial for conserving the energy, reducing carbon emission, and improving the comfort level of the indoor air quality and the built environment. To optimize the natural ventilation and air-conditioning design in the early stage of building design, simulation is the only way. Computational Fluid Dynamic is increasingly being used as a tool for the analysis of outdoor and indoor air flow and thermal conditions. For natural ventilation and thermal simulation combines modeling layout, design variable and also setting conditions, running simulation accounts for lots of time.
The goal of this research is to provide the raw data for building designer, researcher and also calculate the approximate equation to predict others data with the highest accurate as much as possible. This research uses different building layouts, opening ratios, shading coefficients, materials as the design variable to run simulation.
