Abstract

This study designed a workflow for analyzing the annual stack ventilation potential in low-rise atrium buildings. The workflow consists of three steps. The first is to use building performance simulation (BPS) tools to generate a raw ventilation schedule and to build a temperature database of concerned zones and surfaces. The second is to calculate the air flow rate under different boundary conditions obtained from the last step by using computational fluid dynamics (CFD) tools. The third is to repeat step one to refine the ventilation schedule, based on which the daily stack ventilation potential could be determined. The workflow is recommended to be realized by combining Honeybee (EnergyPlus) and Butterfly (OpenFOAM) that are embedded in Rhino_Grasshopper. A case study using a two-story atrium building in Nanjing was conducted. The results show that April has the most high-potential days, which can provide a reference for the guidance of atrium use.
