A Simulation-based Research on Passive District

This paper is aiming to propose a new design concept named passive district which assists designer to improve district energy efficiency and reduce energy demand by smart urban design without mechanical dynamics method. Furthermore, specific simulation-based experiment is implemented to demonstrate the research methodology on correlation between urban form and energy performance, in which the workflow is summarized as follows: definition of constants and variables, modeling, simulation, data sorting and decision making. This urban modeling integrates the morphological factors together including grid size, floor area ratio, cover ratio, passive zone ratio, surface to volume ratio and so on and compares the energy impact respectively. Particularly a method of multi-disciplinary design optimization (MDO) is applied to analyze how multiple factors affect energy use comprehensively and support scientific decision making. Finally, as conclusion the application potential of passive district is discussed.
