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 c...

Madurai, a temple city in Tamilnadu, India has experienced rapid urbanisation that has been resulting in an UHI since 1990. This present study examines changes in LST as an indicator of UHI by analysing the changes in land use land cover (LULC) and normalised difference vegetation index (NDVI). The analysis of these parameters indicates that higher LST is experienced in built up areas whereas lower LST is experienced in areas where green cover is more. This study further investigates the efficiency of various green cover types (trees and turfs) and optimum green plot ratio to mitigate air temperature by using Envi-met simulation software for the particular context. The findings of this study and further explorations on green spaces can be applied theoretically for improving urban planning and for mitigating the UHI effects.

The objective was to capture the complexity and character of naturally grown fishing settlements through simple rules and incorporate them in the process of design. A design tool was developed for this purpose. This design tool used a generative evolutionary design technique, which is based on multidisciplinary methods. Facets of designing addressed in this research are: • allocation of each design element’s space and geometry, • defining the rules, constraints and relationships governing the elements of design, • the purposeful search for better alternative solutions, • quantitative evaluation of the solution based on spatial, comfort, complexity criterions to ensure the needed complexity, usability in the solutions. Generative design methods such as geometric optimisation, shape grammars and genetic algorithms have been combined for achieving the above purp...

It attempts to harness and integrate some of the qualities of organic design process into computer-aided design, capture the complexities of an organic solution and apply it to the housing design decisions. The two complementary fields of Shape Grammar and Generative Evolutionary Design have been converged for this purpose. Shape Grammar is used to extract the style and aspects of organically evolved fisherman?s housing settlement. Generative Evolutionary Design which uses genetic algorithms as a search mechanism is used to explore alternatives and to evaluate the generated design for its functional and usability values and identify the fitter solutions.
Many settlements like the fishermen?s habitat have organically developed and embody the complex r... more Many settlements like the fishermen?s habitat have organically developed and embody the complex relation between land characteristics, functional activities and social aspirations. However, the recent rehabilitation and planning projects, constrained by technical and inscriptional rigidities, have become relatively fixed, formal and monotonous. This research attempts to harness and integrate some of the qualities of organic design process into computer aided design. The two complementary fields of Shape Grammar and Genetic algorithm have been converged for this purpose.
