The traditional efforts of mitigation of air pollution in the urban context are costlier and time intensive and may not always in getting the fruitful results. The built-up environment has been observed to affect the air pollution levels of the city. The effect however is not very straightforward since the built-up form consist of varied forms such as buildings, residential cover, natural morphology, vegetation cover and each exhibit further variating effects on the air quality. This study aims at understanding these relations of built environment with the air quality and derive suitable solutions for the study area of Delhi, India. This would be done by applying the two methodologies: literature review of the studies involving different indicators such as urban form matrix, vegetation, air ventilation and correlation; and air dispersion model simulation using ADMS Urban. Results from matrix of the literature review indicate various built environment aspects significantly alter the air quality and hence urban planner should accommodate it into the planning. Results from air dispersion model suggests that the rate of air pollution dispersion is vastly dependent on the air ventilation which in tern significantly related to the built-up type of the city space. Both the results indicate that it is very critical for the policy maker and planners of Delhi city to consider built-up options which tend to mitigate the effects of air pollution.
Key words: Air Pollution, Dispersion, Ventilation, Urban-structure, Urban-planning, buildings, vegetation, Land use, Simulation, ADMS Urban.
