Modeling of indoor-outdoor air-exchange in a multi-unit residential building

The paper presents the first stage of a research project aiming to model the impact of air leakage on pressure regimes, resultant air movement and energy use in high-rise residential buildings. Simplified simulations for small sections of the building for which experimental data are available are carried out. The objective is to develop and validate a model and to extract important information for the whole building transient simulation (second stage of the research). The most important parameters to be considered when simulating air leakage in a high-rise residential building are identified and preliminary results for the air leakage and related energy consumption are presented.
