The Integrated Effects of Urban Form and Trees on the Microclimate: A Case Study

I. Chandramathy, Jinu Louishidha Kitchley


The Integrated Effects of Urban Form and Trees on the Microclimate: A Case Study Urban greening and urban planning strategies play pivotal roles in creating cooler urban environments. This research is aimed at the optimization of urban planning strategies to achieve cooler micro climate. It investigates the integrated effect of street geometry (with respect to aspect ratio), street orientation, and type of urban canyons (linear wall to wall construction and detached buildings) along with the presence of vegetation, in the microclimate of Madurai, Tamilnadu, India. The parametric study employs three dimensional, holistic, microclimate model with field measurements to identify the effects of the above said conditions on the microclimate. Parameters such as Potential Temperature and Universal Thermal Comfort Index are recorded as criteria for evaluating human comfort and microclimate cooling. The results of the study have proven that there is a direct relationship between the type of canopy and the height of the plants with the intensity of cooling.
