- Title
Multifamily Buildings: Controlling Stack Effect-Driven Airflows.
- Authors

- Abstract
The article discusses the use of the compartmentalization principle to control stack effect-driven airflows in high rise buildings. Stack effect-driven airflows consist of smoke control and fire safety and affect the quality of air and comfort in tall buildings. Stack effect-driven interior airflows can be controlled by detaching the units from each other and corridors, shafts, elevators and stairwalls. Elevators should be located in vestibules and lobbies and unit doors must be weather-stripped. Ventilation is offered to each individual apartment unit across exterior walls under the principle of compartmentalization. Distribution of heating, cooling and hot water should also be done on the basis of compartmentalization principle. There is low maintenance cost of distributed heating, cooling and domestic hot water components as compared to centralized system of heating, cooling and hot water. The ANSI/ASHRAE Standard 62.2, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings, should also be applied to apartments and condominiums irrespective of height.
