Theme B: Creating a livable, healthy and environmentally viable cities2.3 In Tune with the Wind Environmental InitiativesIn achieving the objectives to optimize estate planning, disposition/orientation ofblocks and building permeability, we apply computer fluid dynamics (CFD)analysis to study the wind flow pattern and magnitude at low, mid, high zones ofthe high rise domestic towers for different enhancement measures in site planningand building design options, external circulation and open spaces, and impact onas-built surroundings. By comparing the micro-climate study results of variousgreen initiatives, the most optimal planning and design option is worked out onboth qualitative and quantitative basis in a scientific approach –Figure 4:Environmental Performance with and without Wind Corridora)Effectiveness of “Wind Corridor” design, in quantitative terms, for enhancingsite permeability for prevailing wind is identified by comparing simulation resultsof ‘Before’ and ‘After’ implementation of the development. The increase in airvelocity with wind corridor under the prevailing East wind condition ranges from18 to 250%.485
