SIMULATION OF MICROCLIMATE FOR JURONG LAKE DISTRICT

Abstract

With the increasing population in Singapore due presence of more foreign talents and investors, it will be necessary for new developments to be constructed to meet the needs of people. High living cost is an issue and 36.7% of electricity bills consumptions were found to be related to air-conditioning in 2012. In order to tackle these two issues, it is essential for the next Central Business District, Jurong Lake District to have proper planning. STEVE tool and ENVI-met will be used to simulate different variations and analysis will be done to understand the impact of Urban Heat Island on Jurong Lake District. Studies have shown that roads contribute to Urban Heat Island while increasing greenery and improving air flow are the solutions. Simulation results have shown that there are positive and negative impacts for different variations under different conditions. The increase in greenery and wind speed helps in reducing the temperature in the area for both commercial and residential areas in this study. Roads have a negative impact in general. However, the change in building heights differs for two different situations whereby wind condition and shading plays an important role in affecting the temperatures. The two main elements that help to reduce hotspots are by introducing greenery and better airflow in the area by increasing the spacing between buildings. This study based on Jurong Lake District has limited information and software capabilities.
