Methodology Sydney's central business district (CBD) is chosen as a case study (33°52′5″S 151°12′44″E, 58 meters above sea level). The figure 6 depicts the urban region that is considered in the analysis.

The simulations discussed in the following section are the result of the different proposals for the mitigation strategies for Sydney CBD area. The goal of the project is to minimize the impact of UHI with incorporating solar power generation in Central Business District of Sydney during extended heat periods. Due to global warming such summerly heat waves are expected to occur more often and be longer lasting in the future (Jacob et al., 2008). The study focused on the selected area in Sydney City, that is known for its relatively warm climate. ENVI-met has been utilized and evaluated to see how different urban design alternatives affect the outdoors' thermal environment. With a common grid resolution ranging from 0.5 to 10 meters, it's a three-dimensional non-hydrostatic local meteorological system used to simulate weather parameters in urban environments. There is a complete radiation budget considered by the model (i.e., reflected and diffused solar radiation, direct radiation, and long-wave radiation). It uses flow behavior and thermodynamics to simulate how meteorological variables change during the day. Vegetation, Buildings, surface properties, soils, and meteorological contour conditions all play a role in the ENVI-met model's
