Abstract:
This study explores the possibility of urban water body induced city cooling in the Sri Lankan context, with special reference to the Beira Lake, Colombo. The research method utilises the computer simulation tool ENVI-met to explore o The effectiveness of an urban water body in influencing the microclimate. o A water body in comparison to an urban green space of similar magnitude. o Microclimatic and thermal comfort changes within selected sites of specific orientations, encompassing existing and simulated morphology. o The effect of, and on the wind pattern around the lake in a holistic design scenario. The simulated results and analysis were limited to the peak time of the day of 14.00hrs of a single day in March. Conclusions show that contrary to established thinking the Beira Lake has a negative effect on the thermal comfort, yet will facilitate better wind and evaporative cooling potential in the immediate surroundings.
