Abstract: Wind driven ventilation in buildings is an effective way of diluting the indoor air for maintaining thermal comfort and acceptable indoor air quality. Visualization of wind induced flow patterns in a building with a water table apparatus is a relatively easier method producing instantaneous results. This work focusses on quantifying the flow patterns obtained from the water table experiments in terms of ventilation metrics like percentage of dead spots, absolute ventilation efficiency, and air changes per hour. These metrics will aid in making design decisions in terms of appropriately orienting the building, sizing, and placing of openings in the building.
