Figure 2. Change in DA of building with and without surrounding buildings in Lallubhai Compound (a), Natwar Parekh Compound (b) and PMG colony (c). Single building model – a computational model where a building was isolated in space from all other artefacts, so that light and air are accessible from all floors and all sides of the building. Urban model – a computation model where the building to be studied was considered to be surrounded by identical buildings on all sides as exists in the real scenario, according to the actual layout of the colony
Figure 3. Volume rendering of air velocity within a typical room in Lallubhai Compound (a), Natwar Parekh Compound (b) and PMG colony (c). The color scheme should be read as follows: Red describes higher air velocity values and blues depicts velocities zero or near zero
Figure 4. Air velocity profile of some representative tenements in Natwar Parekh Compound. Note: X-axis indicates building numbers and house numbers, e.g. 1A denotes ‘A’ wing of building number 1, whereas, 306 denotes 6th house on 3rd floor in that building
Figure 5. Income-wise distribution of tuberculosis patients
Figure 6. Time lapse between shifting to the colonies and occurrence of TB in the household in the three colonies. The X-axis shows difference between the time (in years) the patient caught the infection and the time he/she shifted to the colony, i.e. X = Year of TB infection – Year of Shifting to the colony. Positive values indicate that the person was infected after shifting into the colony, whereas negative values indicate that the person was infected before shifting into the colony. The zero value means that the year of shifting to the colony and year of infection with TB coincided for those particular patients. Note: These are taken from the self-reports of the patients from their own memory
