The temperature of urban air is gradually rising in cities across the globe. This can be mainly ascribed to a number of factors, including reduced green spaces, high building densities that result in low wind velocity, and modifications to surface coating materials. The absorption of solar radiation on dark surfaces and human activity induced warming are caused in part by these variables. The issue is further made worse by the growing need for air conditioning, which increases warmth and releases carbon dioxide. This report's main objective is to do Computational Fluid Dynamics (CFD) simulation studies to investigate an industrial estate's airflow patterns. Finding viable ways to improve airflow and overall performance—which will ultimately result in increased energy efficiency is the goal. To investigate the flow behaviors' within the designated industrial estate, eight CFD simulations were run. Among the eight studies are: 1. Reference Model (East Wind) 2. Reference Model (West Wind) 3. Model 1 – Reference Model with façade guiding vent (East Wind) 4. Model 1 – Reference Model with façade guiding vent (West Wind) 5. Model 2 – Reference Model with bisected buildings (East Wind) 6. Model 2 – Reference Model with bisected buildings (West Wind) 7. Model 3 – Reference Model with bisected buildings & façade guiding vent (East Wind) 8. Model 3 – Reference Model with bisected buildings & façade guiding vent (West Wind) The reference model for studies 1 and 2 was duplicated using Bedok Industrial Park E Blocks 3011–3014. The façade guiding vents for studies 3 and 4 were positioned at the edge of the buildings based on the reference model. For studies 5 and 6, the reference model was bisected at Block 3012 & 3013 to ensure wind can pass through. For studies 7 and 8, additional façade guiding vent was added on to the edge of the building to enhance the flow of the air through the building.
