The design of high-rise residential buildings is especially challenging because of the buoyancy driven stack effect in ventilation ducts and vertical shafts such as stairwells, elevators, and garbage chutes. The primary goal of this study is to help architectural designers and engineers to advance the design methodology for pressure and infiltration control and apply it in high-rise residential buildings. Such “intelligent” buildings save energy and provide a good indoor environment, including high indoor air quality. This study is based on computer modeling and use of analytical and empirical design tools. CONTAM, a multizone modeling tool, was used for detailed airflow, pressure and pollutant distribution and for systematic analyses of different engineering solutions to reduce infiltration in highrise residential buildings. The computational analyses concentrated on 1) envelope air tightness, 2) stack effect control and 3) fire smoke management in stairways and major building corridors. The results of the multizone modeling of the 40-story building indicate that building pressurization effectively controls the air infiltration. “Pumping” air into the corridors at each floor provides a positively pressurized core in all building sections and floors. This positively pressurized core (corridors around the elevator) prevents the flow of odors and other pollutants between apartments on the same floor. Based on these results, we propose that building commissioning engineers develop a procedure to correct building pressurization after the construction phase.
