Simulation case study of stack pressure impact on thermal load in high-rise buildings

The reference building models in the EnergyPlus tool do not consider stack effect. This is an issue for small and low-rise buildings. However, this significant evaluating heating cooling load of high-rise study evaluates quantifies effect energy simulation, EnergyPlus. commercial model set was used as a simulation test bed. vertical multi-stories shaft zones were added inside core zone existing model. Then, airflow network so internal including horizontal directions through well perimeter configured. calibrated against actual pressure distribution between all floors buildings from literature. calibration conducted manually by changing discharge coefficient openings thermal zones. proposed compared to which does quantification with relative mismatch analyzed environment temperature difference indoor outdoor, wind speed. Moreover, impact air mixing infiltration on quantified. result reveals significance calculating load.
