Air flow distribution in a mechanically ventilated high rise residential building.

Air flow measurements and simulations were made on a 13-story apartment building to characterize the ventilation rates for the individual apartments. Parametric runs were performed for specific conditions, e.g., height, orientation, outside temperature and wind speed. Our analysis of the air flow simulations suggest that the ventilation to the individual units varies considerably.

Wind around tall buildings

Tall buildings can deflect high-level wind down towards the ground, producing unpleasant and sometimes dangerous winds in adjoining pedestrian areas. Architects, planners and developers must aim to provide safe and comfortable conditions in open-air pedestrian areas; they should, therefore, understand how the wind flows around buildings and how to control it by good design.
