Purpose: This study aimed to investigate optimization of mechanical pressurization using HVAC system to reduce airflow outflow of elevator doors and infiltration through envelopes due to stack effect in high-rise buildings in winter Method: For this study, air leakage rate into office room through elevator door and building envelope in a high-rise office building were calculated through simulations in several pressurized and de-pressurized conditions. With a network simulation model(CONTAM 3.1), the effect of pressurization/de-pressurization positions was evaluated. As results of simulations, the pressurization method with differential pressurized air volume from the top floor to the final pressurized floor was concluded as the best solution to reduce the pressure difference across the elevator doors. Result: As a result of applying the differential pressurization method for each floor, the amount of inflow of indoor air flow through the elevator door before and after pressurization was reduced by 77% and the amount of infiltration through the skin by 92% under the design outdoor air condition in winter. However, it was found that the amount of additional outdoor air introduced through the air conditioner increased by 39% compared to the previous one, resulting in an increase in the cost of air conditioning heating energy.
